Summary:CUDA_ADD_EXECUTABLE generates invalid VS2012
projects when source .cu file is a relative path beggining with ../
Description: 
An invalid Visual Studio 2012 project is generated when CUDA_ADD_EXECUTABLE is
called with a source file such as:

cuda_add_executable(testFindCuda ../3rdparty/testCuda.cu)

VS complaints that the .cu file is included in both the CustomBuild and None
ItemGroups and the project simply doesn't load. 

However, if the testCuda.cu file is specified with an absolut path everything
works fine.

Steps to Reproduce: 
I have included a toy example to reproduce the problem (check testFindCuda.rar).

1) Just extract the files, and run cmake-gui (Windows) on
testFindCuda/mainProject.
2) Generate a Visual Studio 11 2012 solution.
3) Open the resulting .sln with VS2012 and you'll see that it's broken.

Additional Information: 
In particular it seems that the offending line in the .vcxproj file is:

 None Include=C:\Temp\testFindCuda\3rdparty\testCuda.cu /

Summary:Bug in FindwxWidgets.cmake causes build failure when
more than one C flag is used.
Description: 
FindwxWidgets.cmake parses the output of wx-config and converts it to a list.
The definitions and includes seem to be processed appropriately but whatever is
left is considered a CXX flag.

If more than one flag remains it is left as a cmake list, i.e.:
-mthreads;-fpermissive which gcc chokes on.

On both my Fedora and Fedora mingw-w64 installs only one flag is used and the
issue doesn't crop up.

Steps to Reproduce: 
Attempt to build a cmake based project that uses wxWidgets with more than one
build flag.

Additional Information: 
The following patch worked for me but should be reviewed for appropriateness:

[cmake-developers] New platform file for Cray Compute Node Linux

2014-08-14 Thread Chuck Atkins
I've been using CMake on Cray's quite a bit lately and some of the cross
compilation leaves a bit to be desired.  No particular capability is really
missing but the foo of getting things to build and work seems to be
rather dispersed across various individuals and corners of the internet.
I'd like to start pooling some of this together to be shipped with CMake.

For starters, I'd like to add a Platform file for the cross compilation
target of ComputeNodeLinux.  While it's not entirely different from running
Linux natively, some assumptions from native host Linux build environments
aren't valid and building for it explicitly needs search paths defined by
the Cray environment modules.  It's also distinctly different from the
commonly used Catamount (which is very far removed from the currently used
OS). Attached is a patch for a new Platform file that uses information from
the loaded environment modules on the login nodes to define it's
appropriate path and version info.  I've been using this successfully on
Garnet (an XE6) and Titan (an XK7).

  Regarding the Windows Registry, I've taken a look and it looks
  like there might be some usable keys from the installer which
  could be used, but I'll need to do further digging with all
  the different versions to see what's most usable here.
  
  This turned out to be fairly simple at least for Ice versions
  3.4.0 - 3.5.1, which all have the same naming convention.
  Earlier versions have odd naming conventions and are in
  Wow6432Node so I've not included them (they are obsolete in
  any case, and ICE_HOME can be set to use them).
 
 The Wow6432Node is for distinguishing between 32-bit and 64-bit
 views of the registry.  Just omit it from any registry key path.
 When CMake find_* commands evaluate registry values they take
 into account whether the target architecture is 32-bit or 64-bit
 and prefer the matching registry view.
 
 So, please go ahead and add the registry entries for the earlier
 versions.  Just convert any \Wow6432Node\ to \ in the keys.

OK, done now and it's working fine.

 Other comments:
 
  +# Components can include any of: Freeze Glacier2 Ice IceBox IceDB
  +# IceGrid IcePatch IceSSL IceStorm IceUtil IceXML Slice.
 
 I think each name in the list should be ``quoted`` to clarify
 that it is a name to appear in code.

Done.

  +#   ICE_LIBRARIES - component libraries to be linked
 
 Is that a typo in the docs?  It should be Ice_LIBRARIES.

Yes, fixed now.

  +#   ICE_C_LIBRARY - component library
 
 Although the individual find result is a singular-named cache entry
 the results presented to the project should still be plural-named
 normal variables:
 
  Ice_C_LIBRARY - cache entry
  Ice_C_LIBRARIES - results (even if only one entry)

This is also fixed.

  +set(ICE_HOME NOTFOUND
  +CACHE PATH Location of the Ice installation)
  +mark_as_advanced(FORCE ICE_HOME)
  +
  +set(ICE_BINARYDIR NOTFOUND
  +CACHE PATH Location of the Ice programs)
  +mark_as_advanced(FORCE ICE_BINARYDIR)
  +
  +set(ICE_INCLUDEDIR NOTFOUND
  +CACHE PATH Location of the Ice headers)
  +mark_as_advanced(FORCE ICE_INCLUDEDIR)
  +
  +set(ICE_SLICEDIR NOTFOUND
  +CACHE PATH Location of the Ice slice interface definitions)
  +mark_as_advanced(FORCE ICE_SLICEDIR)
  +
  +set(ICE_LIBRARYDIR NOTFOUND
  +CACHE PATH Location of the Ice libraries)
  +mark_as_advanced(FORCE ICE_LIBRARYDIR)
 
 These hints should not need to be explicitly cached with such
 granularity.  The find_* commands create cache entries for
 their results both to save them persistently and to allow users
 to set them granularly.  The CMAKE_PREFIX_PATH variable allows
 users to add custom prefixes without a per-package _HOME or
 _ROOT variable.

These are all removed.

  +  list(APPEND ice_slice_paths
  +/usr/local/share/Ice-${Ice_VERSION_SLICE2CPP_FULL}/slice
  +/usr/local/share/Ice-${Ice_VERSION_SLICE2CPP_SHORT}/slice
  +/usr/local/share/Ice/slice
  +/usr/share/Ice-${Ice_VERSION_SLICE2CPP_FULL}/slice
  +/usr/share/Ice-${Ice_VERSION_SLICE2CPP_SHORT}/slice
  +/usr/share/Ice/slice)
 
 It looks like a lot of the explicit search location construction
 could be simplified using PATH_SUFFIXES options to the find
 commands.  There should not need to be any explicit copies of
 paths for every common prefix.

I have changed all the find_* code to use PATH_SUFFIXES and the
correct cache variable names.  It certainly has simplified things
quite a bit.

 Another option you might be interested in exploring, but not
 as a requirement for our acceptance of this module, is creation
 of imported targets to hold the find results with usage reqs.
 See the cmake-buildsystem(7) manual:
 
  http://www.cmake.org/cmake/help/v3.0/manual/cmake-buildsystem.7.html
 
 for more info.  See the FindQt4 module for an example.  This
 part could be added as a follow-up change once the main module
 is in though.

OK.  I'll have to read up on this and see what needs doing.
In the meantime, I've attached a revised patch with all the
above corrections included.


Regards,
Roger

Re: [cmake-developers] New platform file for Cray Compute Node Linux

2014-08-14 Thread Chuck Atkins
Updated to allow for static and shared libs (yes, you can use shared libs
on a cray).  The expectation is that your toolchain file will have the
appropriate logic to deal with this.  Something like:

set(CMAKE_SYSTEM_NAME ComputeNodeLinux)
...
if(DEFINED ENV{CRAYPE_LINK_TYPE} AND
   $ENV{CRAYPE_LINK_TYPE} EQUALS dynamic)
  set(_CRAY_LINK_OPTS -dynamic)
else()
  # The default behavior if not specified is explicit static-only linkage
  set(_CRAY_LINK_OPTS -static)

  # If we're using static linking then make sure that CMake explicitly
  # only looks for static libraries
  set(CMAKE_FIND_LIBRARY_SUFFIXES .a)
endif()
...
set(CMAKE_C_FLAGS   ... ${_CRAY_LINK} CACHE STRING  FORCE)
set(CMAKE_CXX_FLAGS ... ${_CRAY_LINK} CACHE STRING  FORCE)
set(CMAKE_Fortran_FLAGS ... ${_CRAY_LINK} CACHE STRING  FORCE)

Any thoughts about that?

cmake $builddir

does exactly that. The ZERO_CHECK visual studio target that is present in every 
cmake generated solution does this: it checks if cmake needs to be re-run. It 
is built before every other target. So your batch file does a lot of things 
that are already done by cmake.

Well unless you explicitly disabled this. But you'd know then.

[CMake] ctest and tracks

2014-08-14 Thread ycollette . nospam
Hello,

I've have configured a project to use dash to save test results.
On thing is not clear in the ctest documentation: what is the use of the 
--track option ? Does it allow to create a new category (like Weekly) and 
submit the test results to this new category ?

Best regards,

YC

Re: [CMake] ctest and tracks

2014-08-14 Thread David Cole via CMake
--track is the same as the TRACK argument to the ctest_start scripting 
command.


   http://www.cmake.org/cmake/help/v3.0/command/ctest_start.html

It will send a dashboard to the named section of a CDash project page, 
but it will NOT create it. You have to create the track (called a 
group in the CDash admin pages) as the CDash project admin first 
before you can send to it.


For example, on the VTK Wiki Examples dashboard, there is a Wiki 
Examples track/group/section, which was created by the project admin 
before dashboards were submitted to that track.

[CMake] Regarding enviroment variables directly used in executables

2014-08-14 Thread Ravi Raman
Hi David,

In our cmake project, we have the following scenario:


1.   add_custom_command() call is as follows:
add_custom_command(TARGET ${TESTTARGETNAME}
  POST_BUILD
  COMMENT Test 
target 1...
  COMMAND 
python ${CMAKE_SOURCE_DIR}/testthetargets.bat TestTarget1 ${TESTBIN}
 )


2.   The code in the batch file testthetargets.bat is as follows:

It invokes a project specific executable testtarget1.exe.

The source code of  testtarget1.exe has calls to get few environment variables 
using getenv() function call.



For example, a sample getenv() call is as follows:

target2_exe_path = getenv(TARGET2_EXE_PATH);



So, here the above getenv() call is supposed to get the value of environment 
variable TARGET2_EXE_PATH.

Issue we are facing is as follows:

1.   We set environment variable TARGET2_EXE_PATH using the following cmake 
SET command before the add_custom_command() execution:

SET(ENV{TARGET2_EXE_PATH} C:/Test/Target2)

2.   But when the add_custom_command() gets executed, we observe that the 
environment variable TARGET2_EXE_PATH is not getting reflected in the above 
getenv() call in the source code of  testtarget1.exe. The getenv() call returns 
an empty string.

But this issue does not occur when TARGET2_EXE_PATH environment variable is set 
from Windows directly (i.e. from System Properties - Advanced - Environment 
Variables). In that case, TARGET2_EXE_PATH gets reflected in the above getenv() 
call.

So, basically the call to SET(ENV{TARGET2_EXE_PATH} C:/Test/Target2) has no 
impact on the call to getenv() in the source code.

Kindly let us know if there is any other way in this case other than setting 
the TARGET2_EXE_PATH environment variable from Windows directly ?

Thanks  Regards

Re: [CMake] Regarding enviroment variables directly used in executables

2014-08-14 Thread David Cole via CMake
A SET(ENV{TARGET2_EXE_PATH} C:/Test/Target2) call in a CMakeLists 
file only has an effect while CMake is running.


If you need the env var set for your batch file to run, you should pass 
the value for it down in as an arg to the batch file, and then do:


   set TARGET2_EXE_PATH=%~1

(no quotes in the batch file set, %~1 means arg 1 to the batch file, 
but with any surrounding quotes stripped...)



HTH,
David

--track is the same as the TRACK argument to the ctest_start scripting

http://www.cmake.org/cmake/help/v3.0/command/ctest_start.html

It will send a dashboard to the named section of a CDash project page, 
but it will NOT create it. You have to create the track (called a 
group in the CDash admin pages) as the CDash project admin first 
before you can send to it.

For example, on the VTK Wiki Examples dashboard, there is a Wiki 
Examples track/group/section, which was created by the project admin 
before dashboards were submitted to that track.

This does not work here. cmake $builddir does a full

We have a fairly large project with about 400 targets.
 $ cmake %builddir%

 $ cmake --build %builddir% --target ZERO_CHECK
 - takes 20 seconds for No-op




The ZERO_CHECK visual studio target that is present in every cmake generated 
solution does this: it checks if cmake needs to be re-run. It is built before 
every other target. So your batch file does a lot of things that are already 
done by cmake.


If the build is started from command line (cmake --build  or msbuild 
directly) your wont get the Project has changed! Abort and 
Reload?-Dialog. The old solution will be build. You need to execute the 
build-process a seconds time. Or - as the script does - start a separate 
ZERO_CHECK before the actual build.

This is the problem.

cmake %builddir% should be as fast as possible for a no-op... If it's 
not, it would be good to solve the real underlying problem that causes 
it to take 5 minutes for nothing rather than write elaborate scripts 
to try to workaround it.


Is your project publicly available so CMake devs can try to figure out 
why it takes so long?


Or... can you produce a generated repro case that demonstrates a long 
no-op time?


There must be something in your project's CMake code that triggers the 
performance problem.


Does it still happen with the latest release (CMake 3.0.1)?

I already had a look into our large generation time. They are multiple 
reasons, not one big issue which can be solved easily.



But with all due respect, its not just a 'workaround'. I do not want to 
re-compile things that haven't changed, so i also do not want to 
re-generate if nothing has changed.


A ZERO_CHECK (comparing timestamps of all used CMakeLists.txt) will 
always be faster than generating the project.



Test with CMake 3.0.1 configuring CMake itself:

  $ git describe
  v3.0.1-1690-geb3b550

  $ cmake --version
  cmake version 3.0.1

  CMake suite maintained and supported by Kitware (kitware.com/cmake).

  $ time cmake build
  -- Configuring done
  -- Generating done
  -- Build files have been written to: D:/Playground/cmake/cmake/build

  real0m14.414s
  user0m0.000s
  sys 0m0.015s

  $ time cmake --build build --target ZERO_CHECK
  Microsoft (R) Build Engine version 4.0.30319.17929
  []

  real0m0.421s
  user0m0.000s
  sys 0m0.015s


So ZERO_CHECK is 34 times faster. Why shouldn't I take advantage of that.

If CMake does not need to re-run, then ZERO_CHECK will always be faster 
than cmake build_dir.  cmake build_dir will run a full configure and 
generate no matter what.   That said, a cmake --build all, should do the 
same thing.  Going back to your original question:




For our Continuous Integration tests we need fast incremental builds (only 
build what has changed).
This also includes that CMake only has to run if necessary (some CMakeLists.txt 
changed).
It seems there is no beautiful/portable/generator-independent way to do this?!


The way to do this is to use a ctest script.  You can basically do all 
the stuff in your batch script.  It would be something like this:


if(NOT EXISTS ${BULD_TREE)
do_configure_and_build()
endif()

function(do_configure_and_build)
  ctest_update()
  ctest_configure()
  ctest_build()
endfunction()

Usually, it should be enough to have your version control system tell 
you if something has really changed.  If so, you will want to do a 
configure/build.

Re: [CMake] Resetting CMAKE_Fortran_FLAGS for a specific file

2014-08-14 Thread Glenn Coombs
In my opinion this is a deficiency in how cmake currently works with object
libraries.  If one of the source files in an object library depends on a
third library then it should be possible to specify that in the link
interface of either the object library or the source file.  It is wrong to
have to specify the dependency multiple times for every library or
executable that uses the object library.  It is a property of the object
library, not the users of the object library.

I believe there is already a enhancement request open for something like
this.

Hi Marco.
   
Sane compilers allow later command-line options to override earlier
ones,
so what you're doing should be fine. Unfortunately, I know some
  Fortran
compilers are not sane in this regard.
  
   Here, I would really like to reduce as much as possible the flags
   regardless of the chosen compiler, so undoing the chosen flags
   seems to me cumbersome and compiler dependent, compared to resetting
   them altogether. I like the idea of OBJECT libraries better (it also
   solves other problems I have, I did not know about it!).
  
If you really need to solve this by explicitly modifying the global
list
for a particular file, the only thing I can think of is move those
files
   to
a separate CMakeList and turn them into an object library:
  
   This almost works, I have a problem specifying liking dependencies
 for
   the OBJECT libraries. With a normal library, I can use
  
   TARGET_LINK_LIBRARIES( my_library ${other_libs_my_library_depends_on}
   )
  
   but if my_library is OBJECT I see the error
  
 Object library target my_library may not link to anything.
  
  
   See http://www.cmake.org/cmake/help/v3.0/command/add_library.html for
  the
   correct way to do things with object libraries - for this purpose,
 they
  are
   closer to source files than libraries, which makes sense given that
  there's
   not actually a library written to disk anywhere.
 
  Mark, thanks, but here I don't find anything that answers my question,
  namely specifying that my OBJECT library (i.e. the files included in
  it) require other libraries for linking.
 
 
  The object library is never linked, so the issue of linking with it or to
  it does not arise. The targets that use the object library have
 transitive
  linking dependencies, just like you had if the source files in the object
  library had been directly specified as part of those targets.

 OK, let me see if I understad it. Using the example in

 http://www.cmake.org/Wiki/CMake/Tutorials/Object_Library

 let us say I have


 # A/CMakeLists.txt
 add_library(A OBJECT ${A_srcs})

 # B/CMakeLists.txt
 add_library(B OBJECT ${B_srcs})

 # CMakeLists.txt
 add_subdirectory(A)
 add_subdirectory(B)
 add_library(big ${other_srcs} $TARGET_OBJECTS:A $TARGET_OBJECTS:B)


 and I know that whenever I link the files listed in ${A_srcs}, i.e.
 whenever I likd the OBJECT library A, I also need to link
 libsomeotherlibrary.a . Then in the main CMakeLists.txt I add

 TARGET_LINK_LIBRARIES( big someotherlibrary )

 right?


 Moreover, there is no way to specify someotherlibrary in
 A/CMakeLists.txt, it has to be done where I define the target big,
 namely in the main CMakeLists.txt. Is this correct?


 Thanks,
Marco

Re: [CMake] Windows RC files with Ninja

I found a workaround. Turns out that the issue is caused when not enabling C 
language support in the project() command. i.e I was doing

cmake_minimum_required( VERSION 3.0.0 )
project( proj CXX)

Changing this to

cmake_minimum_required( VERSION 3.0.0 )

fixes the issue.

 Greetings,

 I tried to move from 2.8 to 3.0.1 today and I'm experiencing an issue with RC
 files. Looks like a simple problem but I would be baffled if I'm the first to
 experience this so I expect I have some kind of configuration issue. Here is
 the offending snippet in the rules.ninja file:

 rule RC_COMPILER
   depfile = $DEP_FILE
   deps = gcc
   command =  RC $in $DEP_FILE $out  c:/Program Files (x86)/Microsoft
 Visual Studio 12.0/VC/bin/cl.exe
 c:\PROGRA~2\WI3CF2~1\8.1\bin\x86\rc.exe  $FLAGS $DEFINES /fo$out $in
   description = Building RC object $out

 If I put the path to cmcldeps.exe in the empty quotes on the command
 line, it works as expected.

 Does anyone else have this problem?

[CMake] Viewing the full build log from the CDash Dashboard

2014-08-14 Thread Matt.Bolger
Apologies if this is a stupid question with an obvious answer staring me in the 
face but...

How does one view the full build log from the dashboard? This relates to our 
own dashboard but looking at a build of CMake as an example  
(http://open.cdash.org/buildSummary.php?buildid=3450103) The full output of the 
configure step seems to be displayed on the buildSummary page but there's 
nothing for the actual build (gmake in this case) step. CDash will show a 
cut-down summary of where it thinks the errors or warnings are but sometimes 
(especially with parallel builds) these are wrong (or false positives) or 
alternatively everything succeeded but you still want to browse through the 
build output.

Our current build system captures the output of the ctest process and emails it 
separately but surely this must be available through CDash?

Thanks
Matt

[CMake] Using a custom preprocessor

2014-08-14 Thread Paul Anton Letnes
Hi!

I am currently working on a project which uses plain old make as a build 
system. Needless to say, adding new compilers etc. is a lot of work, so I would 
like to start using CMake, which I have had excellent experience with in the 
past.

There is one peculiarity that I do not know how to handle. Some of our code (C 
and Fortran) is contained in files that end with .cs or .fs, which are run 
through an in-house preprocessor. A Makefile target is then something along the 
lines of (but not exactly)

foo.o: foo.f
$(FC) -c $(FFLAGS) foo.f

foo.f: foo.fs
custom_preproc foo.fs -o foo.f

Is it possible to, somehow, add this pre-compilation step for such files, and 
then
add_executable(myexe
foo.fs
bar.cs
main.f90)
?

Cheers,
Paul
