[CMake] CPack and executable permissions on linux

[Kristian]

Hey guys,

I am creating a RPM package with CMake. Here is a small example of how it
looks:



cmake_minimum_required(VERSION 3.5)

set(BOOST_LIB "${CMAKE_CURRENT_SOURCE_DIR}/boost")

file(GLOB_RECURSE BOOST_LIBRARIES ${BOOST_LIB}/*)

install(FILES ${CMAKE_CURRENT_SOURCE_DIR}/usr/bin/executable DESTINATION
bin)
install(FILES ${BOOST_LIBRARIES} DESTINATION lib)

set(CPACK_GENERATOR "RPM")
set(CPACK_PACKAGE_VERSION 6.5)
set(CPACK_PACKAGE_NAME "executable-proj")
# set(CPACK_RPM_PACKAGE_NAME "executable-proj")
set(CPACK_RPM_PACKAGE_SUMMARY "Simple executable project")
set(CPACK_RPM_PACKAGE_ARCHITECTURE x86_64)
set(CPACK_PACKAGE_VENDOR "Some Vendor Limited")
set(CPACK_RPM_PACKAGE_MAINTAINER "Some Vendor Limited")
set(CPACK_RPM_PACKAGE_AUTOREQ "NO")
set(CPACK_PACKAGE_EXECUTABLES "executable")

INCLUDE(CPack)

==

Before running this cmake script, I am setting executable permissions on
the build machine, where the package is created.

Then, I create a docker image, where this RPM is downloaded and installed.
But when I want to start the executable within a docker container, then I
am getting the message "permission denied".
When I look at the permissions of my installed package, then I see, I only
have read permissions.

So the question is: What can I do for getting executable permissions for
this executable? Is this a CMake/CPack problem?

Re: [CMake] CPack and executable permissions on linux

[Kristian]

Thanks for all answers. I had to read the documentation before asking :-D

I changed the line for the executable from
> install(FILES ...
into
> install(PROGRAMS ...

That worked and as far as i can see is sufficient for my requirements.

Re: [CMake] execute_process, cmd /c and vcvarsall

[Kristian]

After some tries I found maybe a solution for you. In my small example, I
had these lines, which are working:


> set(HELLO1 "C:/Program Files (x86)/Microsoft Visual Studio
14.0/VC/vcvarsall.bat")
> execute_process(COMMAND ${HELLO1} && msbuild /help WORKING_DIRECTORY
"${CMAKE_CURRENT_SOURCE_DIR}")

So for you, it would look like this (I am not very sure about it):

==


execute_process( COMMAND $ENV{VS${VS_IDE_VERSION}
0COMNTOOLS}../../VC/vcvarsall.bat x86_amd64 &&  ${CUDA_NVCC_EXECUTABLE}
${OpenCV_SOURCE_DIR}/cmake/checks/OpenCVDetectCudaArch.cu --run

 WORKING_DIRECTORY
"${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeTmp/"

 RESULT_VARIABLE _nvcc_res OUTPUT_VARIABLE _nvcc_out

 OUTPUT_STRIP_TRAILING_WHITESPACE)

==

Anyhow, when I tried several types of your presentation, I got always some
errors. I do not know, if this is a bug or not, but I will write them down
here. Maybe some of the others could write something about it.


*** First try ***

> set(HELLO1 "C:/Program Files (x86)/Microsoft Visual Studio
14.0/VC/vcvarsall.bat")
> execute_process(COMMAND cmd /c "call ${HELLO1}" WORKING_DIRECTORY
"${CMAKE_CURRENT_SOURCE_DIR}" RESULT_VARIABLE _nvcc_res OUTPUT_VARIABLE
_nvcc_out)
> message("${_nvcc_out}")

When I call these lines on a windows machine, I am getting the error

> 'C:/Program' is not recognized as an internal or external command,
operable program or batch file.

*** Second try ***

When I change the execute_process to this

> execute_process(COMMAND cmd /c "call \"${HELLO1}\"" WORKING_DIRECTORY
"${CMAKE_CURRENT_SOURCE_DIR}" RESULT_VARIABLE _nvcc_res OUTPUT_VARIABLE
_nvcc_out)

then I am getting this error

> '\"C:/Program Files (x86)/Microsoft Visual Studio
14.0/VC/vcvarsall.bat\"' is not recognized as an internal or external
command, operable program or batch file.

So now, CMake / Batch recognizes the right path, but somehow there are the
characters \".

*** Third try ***

I changed the definition of the variable HELLO1 into (because of some hints
here
https://superuser.com/questions/279008/how-do-i-escape-spaces-in-command-line-in-windows-without-using-quotation-marks
)

> set(HELLO1 "C:/Program^ Files^ (x86)/Microsoft^ Visual^ Studio^
14.0/VC/vcvarsall.bat")

But here, I am also getting the error

> 'C:/Program' is not recognized as an internal or external command,
operable program or batch file.

Even, when I double the carets ^^, then the same error occurs

Without of some more information, I could not give you a hint, where the

Re: [CMake] CPack change file extension

[Kristian]

Hey,

you're working on Windows, right?

I think you can do that if you create an additional target and call that
target. So let's say, you have this 'hello.cpp', and you generate with
CMake a solution. This is an example of a CMakeLists.txt

> cmake_minimum_required(VERSION 3.4)
> project(cpack_zip_test)

> set(SOURCES hello.cpp)

> add_executable(${PROJECT_NAME} ${SOURCES})

> set(CPACK_GENERATOR "ZIP")
> set(CPACK_PACKAGE_EXECUTABLE ${PROJECT_NAME})
> set(CPACK_PACKAGE_FILE_NAME ${PROJECT_NAME}-package)

> add_custom_target(rename_zip
> COMMAND rename ${CPACK_PACKAGE_FILE_NAME}.zip
${CPACK_PACKAGE_FILE_NAME}.docx
> WORKING_DIRECTORY ${CMAKE_SOURCE_DIR})

> include(CPack)

When I call now something like this on the command line (Visual Studio 12
2013)

> devenv cpack_zip_test.sln /Rebuild Debug /project PACKAGE.vcxproj

and afterwards some like this

> devenv cpack_zip_test.sln /Rebuild Debug /project rename_zip.vcxproj

then this is some way of renaming your zip into a docx file. But I do not
know, if there is a more automatic way to do this. I tried it with an
additional parameter in the 'add_custom_target'-command (see at the DEPENDS
part):

> add_custom_target(rename_zip
> COMMAND rename ${CPACK_PACKAGE_FILE_NAME}.zip
${CPACK_PACKAGE_FILE_NAME}.docx
> DEPENDS PACKAGE
> WORKING_DIRECTORY ${CMAKE_SOURCE_DIR})

But when I call 'devenv cpack_zip_test.sln /Rebuild Debug /project
rename_zip.vcxproj', I would assume, that first the PACKAGE target is
called, and afterwards the 'rename_zip' target is called. But that's not
the case. Maybe some other person can tell me, if this is a bug or this is
intention...

[CMake] CPack - Transaction error

[Kristian]

Hi,

I want to generate a RPM package. My CMakeLists.txt looks loke this:

##

cmake_minimum_required(VERSION 3.5)

set(INSTALL_DIR ${CMAKE_INSTALL_PREFIX}/ssp/)

install(DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}/ssp-suite/" DESTINATION
${INSTALL_DIR})
install(PROGRAMS "${CMAKE_CURRENT_SOURCE_DIR}/ssp_script" DESTINATION bin)

set(CPACK_RPM_PACKAGE_REQUIRES "java-1.8.0-openjdk >= 1.8.0")

# ...

INCLUDE(CPack)



The idea is to install needed files for the software under /opt/ssp.
Now I generate a package with command

> cmake -DCMAKE_INSTALL_PREFIX=/opt -V --debug .

When I want to install that in a docker container, I get the error message



Transaction check error:
  file /opt from install of ssp-suite-7.1-1.x86_64 conflicts with file
from package filesystem-3.2-21.el7.x86_64

Error Summary



What is the problem?

[CMake] RPM package and relocation

[Kristian]

Hi,

I am creating an RPM package, which on a standard installation should
install the file into /opt/ssp-suite directory. But I want to give the
user the opportunity, to install the package into another directory.

I am doing this with these lines:

> set(INSTALL_DIR ${CMAKE_INSTALL_PREFIX}/ssp-suite)
> install(DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}/ssp/" DESTINATION 
> ${INSTALL_DIR})

and by running cmake with

> cmake -DCMAKE_INSTALL_PREFIX=/opt -V --debug .

But I also need to execute a post script, which runs after installation. I added

> set(CPACK_RPM_POST_INSTALL_SCRIPT_FILE 
> "${CMAKE_CURRENT_SOURCE_DIR}/postinstall")

to my CMakeLists.txt and in that script, I am using the RPM variable
$RPM_INSTALL_PREFIX. But during installation, I get this error message

> chmod: cannot access '/usr/usr/bin/startssp': No such file or directory
> warning: %post(ssp-suite-7.1-1.x86_64) scriptlet failed, exit status 1
> Non-fatal POSTIN scriptlet failure in rpm package ssp-suite-7.1-1.x86_64

Can someone give me some hints, how to change / add lines to
CMakeListst.txt and my postinstall script, so that script can be fully
relocatable?

[CMake] Create user and group with CPack

[Kristian]

Hi,

I create a RPM package with CPack. When installing this package on a
target system, it should create an additional user and group.

My current solution is a postinstall script, wich runs at the end of
the installation. There, I added commands to create a user and a group
(groupadd, useradd). But somehow, they aren't created when installing
this RPM package. For testing, I install this RPM package in a docker
container.

I also tried, if these commands (groupadd, useradd) are working on the
docker container and they are, so this shouldn't be a problem.

So, how can I create a user and a group with CPack / CMake?

Re: [CMake] Create user and group with CPack

[Kristian]

Hi,

thank you for your reply. Yes, I add the script with
> set(CPACK_RPM_POST_INSTALL_SCRIPT_FILE 
> "${CMAKE_CURRENT_SOURCE_DIR}/postinstall")

and it basically works, because this file is changing a settings file
without any problems. Only the add of the group and the user does not
work, somehow.

This is the part in the postinstall script, which should add group and user:

=
WEB_USER=web1
WEB_GROUP=web1

# create group
groupadd "${WEB_GROUP}" --force --system
# retrieve group id
WEB_GROUP_ID="$(getent group '$WEB_GROUP' | cut -d: -f3)"
echo "Group '${WEB_GROUP}' added with id '${WEB_GROUP_ID}'"
# create user
useradd "$WEB_USER" -g "${WEB_GROUP_ID}" -M -r -s /sbin/nologin -c
"Web user - created during the installation."
echo "User '${WEB_USER}' added."
=

And this is, what is being printed during installation:
=
Group 'web1' added with id ''
useradd: group '' does not exist
User 'web1' added.
=

Re: [CMake] Create user and group with CPack

[Kristian]

Ok, I changed the postinstall script based on your suggestions:

i.e. I changed these two lines:
> WEB_GROUP_ID="$(getent group "${WEB_GROUP}" | cut -d: -f3)"
and
> useradd "$WEB_USER" -g "${WEB_GROUP}" -M -r -s /sbin/nologin -c

And it worked now. Thank you for your help. :)

[CMake] PreprocessToFile

[Kristian]

Hi,

I have a Visual Studio 2015 Solution with some C++ projects in it. I
try to generate the same solution and the projects with CMake. Now,
there is a part, where I do not know how to solve this.

In a vcxproj file, there is something like this written:

=


  
false
  

  
false
  

=

So, now my question: Is it possible, to get the same result with CMake here?

[CMake] CMake and a simple java example

[Kristian]

Dear All,

I am learning CMake, and one of my personal lessons is combine Java
and CMake. I made a small example (HelloWorld.java):

==

public class HelloWorld
{
   public static void main(String[] args)
   {
  System.out.println("Hey :)");
   }
}

==

And a CMakeLists.txt file:

==

cmake_minimum_required(VERSION 2.8)
project(HelloWorld)

find_package(Java REQUIRED)
include(UseJava)

set(JAR_NAME HelloWorld)
set(JAVA_SOURCE_DIRECTORY )
set(JAVA_SOURCE_FILES ${JAVA_SOURCE_DIRECTORY}/HelloWorld.java)
add_jar(${JAR_NAME} ${JAVA_SOURCE_FILES})

==

Then I go into that directory where the CMakeLists.txt is and start the command

==
cmake --target=HelloWorld --build .
==

Output is:

==

-- The C compiler identification is GNU 4.8.4
-- The CXX compiler identification is GNU 4.8.4
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Found Java: /usr/bin/java (found version "1.8.0.66")
-- Jar file /home/some/Downloads/HelloWorld/HelloWorld.jar
-- Class compiled to /home/some/Downloads/HelloWorld/CMakeFiles/HelloWorld.dir
-- Configuring done
-- Generating done
-- Build files have been written to: /home/some/Downloads/HelloWorld

==

But when I start the command "make", then I get the following output:

==

Scanning dependencies of target HelloWorld
make[2]: *** No rule to make target `/HelloWorld.java', needed by
`CMakeFiles/HelloWorld.dir/java_compiled_HelloWorld'.  Stop.
make[1]: *** [CMakeFiles/HelloWorld.dir/all] Error 2
make: *** [all] Error 2

==

Can you tell me, what I am doing wrong?

[CMake] CMake and BZip2

[Kristian]

Hey,

I have a small C++ file, which uses some functions of the library
bzip2. On a Debian derivate, I have installed needed packages with

 * sudo apt-get install bzip2 libzip2 libbz2-dev

Here is my CMakeLists.txt:

=

project(bzip2Example)
cmake_minimum_required(VERSION 2.8)

find_package(BZip2)
include_directories(${BZIP2_INCLUDE_DIR})
target_link_libraries(${BZIP2_LIBRARIES})

set(BZIP2_EX_SRC main.cpp)

add_executable(${PROJECT_NAME} ${BZIP2_EX_SRC})

=

Then I type in: cmake . && make

This is the output of the make command:
=
main.cpp: In function ‘int main(int, char**)’:
main.cpp:8:21: warning: deprecated conversion from string constant to
‘char*’ [-Wwrite-strings]
  char *sourceFile = "test.txt";

[CMake] A function and its arguments

[Kristian]

Hey,

I have a question. I have read the article about functions:
https://cmake.org/cmake/help/v3.0/command/function.html

I tried to write myself a very simple function (nothing special)



function(test_me add1 add2)
message("test_me")
message(" -> " ${add1})
message(" -> " ${add2})
message(" -> Number of arguments: " ${ARGC})
message(" -> All arguments: " ${ARGV})
message(" -> 0. argument: " ${ARGV0})
message(" -> 1. argument: " ${ARGV1})
message(" -> 2. argument: " ${ARGV2})
message(" -> Unexpected arguments: " ${ARGN})
endfunction(test_me)



But when calling the function with


test_me("1" "2" "3")


or


test_me(1 2 3)


Then I get this output:


test_me
 -> 1
 -> 2
 -> Number of arguments: 3
 -> All arguments: 123
 -> 0. argument: 1
 -> 1. argument: 2
 -> 2. argument: 3
 -> Unexpected arguments: 3



I would expect, that the line "All arguments" would look like "All
arguments: 1 2 3", and not "All arguments: 123".

What is the thought behind this behaviour?

[CMake] VERSION and SOVERSION in a module

[Kristian]

Hey,

I have a question. I have a project, which is compiled on two
different build machines with ninja (trunk and branch). The
CMakeLists.txt is the same when it comes to a part, where the VERSION
and SOVERSION part is set through the function
'set_target_properties'.

But on the first build machines, setting the VERSION and SOVERSION
works, on the other machine it does not work. On the second machine
(where the build fails), I recently upgraded CMake to 3.5 (I compiled
and installed it on my own). The first build machine has CMake with
version 2.8.11 (installed from local package manager yum).

I've tried some things till I got a minimum example, where I could
reproduce the error. The problem is calling add_library with MODULE.

So, first the CMakeLists.txt
=
cmake_minimum_required(VERSION 2.8)
project(test1)

set(SOURCES func.cpp)

set(VER1 "1")
set(VER2 "2")
set(VER3 "3")

add_library(${PROJECT_NAME} MODULE ${SOURCES})
set_target_properties(${PROJECT_NAME} PROPERTIES LINK_FLAGS
-Wl,-Bsymbolic VERSION ${VER1}.${VER2}.${VER3} SOVERSION 0)
=

When running this script with the commands on the first build machine
(CMake 2.8.11 / this is also reproducable with Unix Makefiles
generator)
> cmake . && make && ls
then I get this

> CMakeCache.txt
> cmake_install.cmake
> func.cpp
> libtest1.so.0
> Makefile
> CMakeFiles
> CMakeLists.txt
> libtest1.so
> libtest1.so.1.2.3

(which seems ok to me)

But running the same CMakeLists.txt on the second build machine (CMake
3.5), then I get this:

> CMakeCache.txt
> CMakeFiles
> cmake_install.cmake
> CMakeLists.txt
> func.cpp
> libtest1.so
> Makefile

Is this an error? Or what should I add to the CMakeLists.txt on the
second build machine, to get the same output (i.e. libtest1.so.0
libtest1.so.1.2.3)?

[CMake] CPack does not generate a RPM

[Kristian]

Hi,

I have an error and I do not know, how to solve this error.

I have an archive, where are some files. I want to generate a rpm
package with the files, which are in that archive. So first, I extract
that archive with a bash script. After that, the script calls "cpack
-G RPM -V ." for this CMakeLists.txt:

cmake_minimum_required(VERSION 3.5)
project(project1)

install(FILES ${CMAKE_CURRENT_SOURCE_DIR}/usr/bin/calculator DESTINATION bin)
install(FILES ${CMAKE_CURRENT_SOURCE_DIR}/usr/lib64/* DESTINATION lib)

set(CPACK_GENERATOR "RPM")
set(CPACK_PACKAGE_VERSION_MAJOR 1)
set(CPACK_PACKAGE_VERSION_MINOR 2)
set(CPACK_PACKAGE_NAME "project1")
set(CPACK_RPM_PACKAGE_NAME "project1")
set(CPACK_RPM_PACKAGE_SUMMARY "Some random calculator")
set(CPACK_RPM_PACKAGE_ARCHITECTURE x86_64)
set(CPACK_PACKAGE_VENDOR "Vendor Coorp.")
set(CPACK_RPM_PACKAGE_MAINTAINER "Vendor Coorp.")

INCLUDE(CPack)

But calling the cpack command, I always getting the error "CPack
project name not specified". Why is that? What I am missing?

[CMake] Fwd: CPack does not generate a RPM

[Kristian]

Ok, one part of the problem, I could solve. I could solve the problem
with running the following commands:

cmake . && make package

After that, I get a rpm package. But now, I have another problem and I
do not know, if I am doing something wrong or if this is a bug.

Let's assume, I have a library, e.g. liblibrary.so.5.6.7 and I have
two symbolic links, so the result of "ls -l" would look like this

liblibrary.so -> liblibrary.so.0
liblibrary.so.0 -> liblibrary.so.5.6.7
liblibrary.so.5.6.7

And let's assume, I have these lines in my CMakeLists.txt:

***
set(LIBRARIES
${LIB}/liblibrary.so
${LIB}/liblibrary.so.0
${LIB}/liblibrary.so.5.6.7)
#...
install(FILES ${LIBRARIES} DESTINATION lib)
***

Now, I call the commands "cmake . && make package" and I get a package
"project1.1-Linux.rpm". After that, I try to install that package with
"yum install project1.1-Linux.rpm", I get some strange dependency
resolution errors, which would look like this

--> Finished Dependency Resolution
Error: Package: project1.1-1.x86_64 (/project1.1-Linux)
   Requires: liblibrary.so.0()(64bit)
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest


But when I have only these lines in CMakeLists.txt

**
set(LIBRARIES
${LIB}/liblibrary.so.0
${LIB}/liblibrary.so.5.6.7)
#...
install(FILES ${LIBRARIES} DESTINATION lib)
**

then installation of my very simple project works and I am not getting
any dependency resolution errors.

Re: [CMake] Fwd: CPack does not generate a RPM

[Kristian]

Thank you for your answer. Setting the variable
CPACK_RPM_PACKAGE_AUTOREQ to "NO" worked.

I also tried to produce a minimal example, which produces such error
as the behaviour I described. But I couldn't generate such an example.
I do not know currently, under which circumstances this happens :(.

My assumptions are the same, that this seems to be a rpm issue.

Re: [CMake] issue with target_link_libraries and MSVC

[Kristian]

I'm not sure, but I think, you should consider 'set_target_properties'
(https://cmake.org/cmake/help/v3.0/command/set_target_properties.html).

E.g.

target_link_libraries(my_target source1.cpp source2.cpp)
set_target_properties(my_target PROPERTIES LINK_FLAGS "\openmp")

[CMake] Freetype on linux systems in non-standard directories

[Kristian]

Hey guys,

I wanted to try something out with CMake and latest version of freetype
(2.6.3). So I downloaded freetype, compiled it with the commands

> ./configure --prefix=/home/kristian/Documents/freetype/freetype
> make
> make install

After that, I created a small C++-file and a CMakeLists.txt. The C++-file
depends on freetype, so my CMakeLists.txt looks like this:

=

> cmake_minimum_required(VERSION 3.5)
> project(freetype_ex)
>
> set(FREETYPE_DIR "/home/kristian/Documents/freetype/freetype")
> find_package(Freetype)
>
> set(SOURCES main.cpp)
>
> include_directories(${FREETYPE_INCLUDE_DIRS})
>
> add_executable(${PROJECT_NAME} ${SOURCES})
> target_link_libraries(${PROJECT_NAME} ${FREETYPE_LIBRARIES})

=

But when calling cmake, I am getting this error:
=

> -- Could NOT find Freetype (missing:  FREETYPE_LIBRARY
FREETYPE_INCLUDE_DIRS)
> CMake Error: The following variables are used in this project, but they
are set to NOTFOUND.
> Please set them or make sure they are set and tested correctly in the
CMake files:
> FREETYPE_LIBRARY (ADVANCED)
> linked by target "freetype_ex" in directory
/home/kristian/Documents/freetype/cmake
>
> -- Configuring incomplete, errors occurred!
> See also
"/home/kristian/Documents/freetype/cmake/CMakeFiles/CMakeOutput.log".

=

This sort of error seems for me to be a bug, because I would assume, that
when I set the variable FREETYPE_DIR, then CMake would also look at this
dir.

I looked at the FindFreetype.cmake file (
https://github.com/Kitware/CMake/blob/master/Modules/FindFreetype.cmake)
and my first assumption is, that it would help, to add something like
${FREETYPE_DIR} the the find_path calls.

What do you think of this? Another idea is, to add another variable instead
of FREETYPE_DIR, e.g. FREETYPE_ROOT_DIR...

[CMake] Visual Studio problem with many/long additional library paths

[Kristian Nielsen]

A cmakelists.txt file of mine contains the following:

This is generated by

cmake -G "Visual Studio 7 .NET 2003"

This looks fine, but unfortunately it seems to break some limit in Visual
Studio version 7.1. There is no error message when loading the project file,
but the paths do not work and libraries can not be found.

The limit seems to be a bit more than 2000 characters. If I shorten the path
to less than that, the build work.

Googling turned up nothing. While this does seem to be a bug / misfeature in
Visual Studio, I wondered if anyone has experienced this problem, and perhaps
know of a workaround? Since CMake uses hardcoded paths, this problem is all
the more likely to hit in CMake-generated projects. I wonder if there is
another way to write the .vcproj files that avoid this limitation...

Re: [CMake] Visual Studio problem with many/long additional library paths

That's great, thanks.

When manually creating a Visual Studio solution, the limitation on
AdditionalLibraryDirectories can be avoided entirely by instead using
dependencies in the .sln file. It seems that if exe A has a dependency on
library B (both projects in the .sln), there is an implicit link of B into a
implied. I wonder if there is a way to generage that with CMake, I tried just
replacing TARGET_LINK_LIBRARIES with ADD_DEPENDENCIES, but that did not seem
to work? I'll play a bit more with it and see if I can find something that
works.
