[CMake] FYI: Where do users of CMake with Eclipse work?

[Martin Weber]

Hi all,

found some interesting download stats for Eclipse plugins that integrate 
CMake.



Just click the globe icon to the right to see downloads by country.

The open build service [1] supports packaging for many distros, including 
Debian.
The project for cmake is here [2]. You could ask the maintainers to add 
building cmake for CentOS/Fedora, too.

They don't! Maybe you find a more recent RPM at https://build.opensuse.org/
 and ask the package maintainer there to also build it for RHEL.
I took the same approach on our company-internal OBS.

Sounds promising. What is it that _modern Eclipse versions can do_?

What does that mean: _an Eclipse project whose source tree reflects what is in 
the filesystem rather than what is defined in the CMake project._ ??

If the IDE indexing all source files takes too long, I would say it is a 
problem with the IDE; but not a problem of cmake's IDE project generator (as 
the topic states).

That's the only way to go in your case. How should the CDT4 project generator 
know about all your source files that do not take part in a build?

Newer versions of CDT (9.1+) seem to have trouble to properly read the 
.cproject file generated by cmake [1] [2]. 

Forget about running cmake manually and install _cmake4eclipse_ from the 
eclipse marketplace. It runs cmake automatically [3] and comes with support 
for the eclipse indexer. Some people even use it for CUDA in the nvidia 
insight IDE. (Disclaimer: I am the maintainer)
Just try it with one of the example projects [4].

There would be no server load of users of the plugin. I plan to change the 
HTML-links in the table-of-content sections to point to cmake.org instead of 
pointing to the the bundled HTML-files.

Packaging the generated html files seems to be the way to go.
But I do not want the html checked in at my github repo (Currently github 
language-details says: HTML 77.6%).
Are the HTML files for cmake docs available in a zip file, so I can let the 
CmakeEd doc build download them? I found them in  but am unsure whether that is the 
proper file to use.

THX,
Martin

[CMake] Additional traffic on cmake.org concerning cmake documentation

[Martin Weber]

Hi,

this is a question to the people at cmake.org.

The CmakeEd plugin for eclipse [1],[2] currently comes with a copy of the 
cmake documentation. Unfortunately, it refers to a fairly outdated version of 
cmake (2.8.6) and the scripts to convert the docs to Eclipse help format do 
not longer work and I have no time to maintain them. 
As the author of CMakeEd, I would like to replace the bundled doc-files by 
online links to documentation on cmake.org.

So my question is: Are there any objections regarding the additional IP 
traffic on cmake.org imposed if CmakeEd-users would browse the online docs 
instead of a local copy? Or would it be preferable to have a download-on-
demand feature for the docs?

CMakeEd currently has about 18k installs and gets roughly 700 more each month.
The attachment show the items to be replaced by online links to cmake.org.

Regards,
Martin

[CMake] Weird @<< in compile_commands.json

[Martin Weber]

Hi,

I see cmake producing a compile_commands.json file that contains a weird 
expression like '@<< /TP -DECAL_LAYER_FASTRTPS <<'.
This expression causes an issue in my cmake4eclipse project [1].

The expression looks like a commandfile-specifiation, but the file `<<` does 
not exist.

So my question:
Is the '@<< ... <<' just an invention of cmake or is it somehow `official`?

Martin

All I found is here <http://dev.eclipse.org/mhonarc/lists/cdt-dev/
msg32845.html>

I also browsed through the new code, but the javadocs are close to non-
existent.

If the cmake devs plan to remove the CDT4 generator, I think that would be OK. 
In 2013, I started an eclipse plugin that automatically runs cmake from 
Eclipse. It's also in the marketplace, so cmake users have an escape.

[CMake] CMAKE_EXPORT_COMPILE_COMMANDS, compile_commands.json content

[Martin Weber]

Hi all,

in the generated compile_commands.json, what are the quoting rules in the 
command fields?
Apart from the fact that a quotation mark in json inside a value has to be 
escaped as *\"*, do the arguments in the command-field follow the shell-
escape rules or do they reflect the arguments passed to exec(1).

Seeing a line in my compile_commands.json starting with

"command": "/usr/bin/c++ -Dprojectname_ROOT_DIR=\\\"/home/username/workspace/
projectname\\\" 

is confusing. What exactly is the value of macro projectname_ROOT_DIR here? A 
string literal?

OTOH, the same line has

-DvtkFiltersFlowPaths_AUTOINIT=\"1(vtkFiltersParallelFlowPaths)\"

which I do recognize as a macro value of string literal type.

Background: My tool tries to get the macro definition from the  
compile_commands.json file [1]

TIA,
Martin

You will have to do so. There is no generator for CMakeLists.txt in CDT.

I wrote a plugin that works with normal C/C++ projects and invokes cmake for 
you. You will find it in the Eclipse Marketplace (cmake4eclipse).

As a start, you may check out the sample projects in

Sounds like you will have to create a custom toolchain file.

[CMake] Is there a way to produce the documentation of cmake in xml format?

[Martin Weber]

Hi all,

is there a way to extract the documentation from cmake-sources and convert 
that to XML? 
I am trying to work on CmakeEd [1]. This Eclipse plugin has support for 
editing cmakelists files (syntax highlighting, code completion), but only for 
cmake 2.8 which I want to update.
If I had docs in XML I could use XSLT to produce my files instead of typing 
all the stuff...

Any ideas?

[CMake] default generator officially supported?

[Martin Weber]

Hi,

in [1] some pointed out that cmake seems to have a notion of _default 
genrator_, that is: If you invoke cmake without the -D option, it chose a 
generator depending on the platform and create the build scripts.

Is this nice feature officially supported by cmake? I could not find it 
documented anywhere.

TIA,
Martin

Re: [CMake] CMAKE - troubles finding executables/paths - Windows 7 / MinGW

[Martin Weber]

Yes, I know this [1] thread is old, but it hurts me, too.

This is what I found:
The mingw32 installer (mingw32-get, IIRC) no longer places a key in the 
windows registry.

So if anyone installed mingw32 in a directory other than c:/MinGW/,
cmake will not find it.
After adding the bin directory of the mingw install location to %PATH%, cmake 
will detect mingw32-make, but it will complain saying 'the compiler is not 
able to build a single program'. 
This happens because cc1.exe (which is *not* in the bin directory) cannot find 
the DLLs located in the bin directory. You have to manually copy the DLLs to 
the directory containing cc1.exe.

Maybe someone finds this useful.

Martin

Hi Nils,

the Eclipse Marketplace has some plugins that help you to work with cmake in 
Eclipse.
Just search for 'cmake'...

Sure. But with the next crawler run, it did not find any download links and 
each jenkins installation forgot the old download links when they did its 
daily update.
BTW, the crawler runs daily, not every 10 days, as earlier reported.

Thank you for restoring index listing.

Solutions could be
- Selective index listing by user-agent header.
- Hosting releases on bintray (it has a query API)

Thank you!

[CMake] Unable to download older releases: Directory index no longer supported

[Martin Weber]

Hi cmake developers,

I hope some of the cmake developers will chime in here...

The download site [1] seems to have been revamped. Since then, it does no 
longer allow to download older releases.

If the devs decided to disable directory listings due to excessive download 
traffic caused by Jenkins instances, please let me know.

I am the maintainer of a Jenkins-plugin [2], that invokes cmake to generate 
the build scripts. I recently added a feature to that plugin, which downloads 
a cmake binary (.tar.gz) from cmake.org and installs it for use of jenkins 
only. This feature seems to be very useful for people that run jenkins build 
nodes under windows or Linuxes that ship with older versions of cmake (e.g. 
RHEL-7 still ships with cmake 2.8.6).
Since the revamp, the download feature fails [3].

Download traffic on cmake.org is caused by the following:

- Jenkins backend crawler [4], runs every ~10 days on the download sites and 
detects newer releases of cmake and announces new versions to plugin users.
- Jenkins slaves (aka worker nodes) that download from cmake.org. Downloads 
happen once per slave and per cmake version, but not per build [5].

It would be nice to keep the download feature working.

TIA,
Martin

If you are building C/C++ sources, set up a CDT project.

makefiles. (I am the author of it).

It is not perfect due to the quirks in CDT, but it avoids that extra manual 
invocation of 'cmake -G whatever'.

 To Whom It May Concern:
 
 I'm using Cmake 3.2.2, specifically the Eclipse CDT4 - NMake Makefiles
 generator.  I am able to successfully run cmake and build from within
 Eclipse but there seem to be things missing from the .cproject file.  For
 example, I've got a source routine with #ifdef _WIN32 and this chunk of
 code is greyed out (i.e. not perceived active) in the Eclipse editor and
 source outline views (see picture below).  I find this surprising since the
 build succeeds (it's ultimately able to find the necessary windows headers)
 and /DWIN32 is defined in CMAKE_CXX_FLAGS.

This may be more related to CDt than to cmake, since cmake just generates the 
makefiles and the Eclipse project files.

Your code is displayed as greyed out, since CDT does not know about the _WIN32 
macro (but the build does know). You may manually add it in the project 
settings, or enable the GCC build output parser plus the gcc builtin specs 
detector to tell CDT about the macro.
The build output parser will find macros and include paths in the gcc command 
lines and add them automatically. Of course, this will not work, if the cmake 
generated build script passes the compiler options in a file:(

[CMake] C/C++ projects: Can cmake generate a '-include file' option for the compiler?

[Martin Weber]

Hi,

is there a way in the cmakelists syntax to generate a build script 
(make/ninja/...) that will invoke the C/C++ compiler with an '-include file' 
or '-include macros' option?
From the GNU cpp man page:

-include file
   Process file as if #include file appeared as the first line of 
the primary source file. ...
-imacros file
   Exactly like -include, except that ...

I do not really believe these options make any sense when using cmake (they 
seem to be GNU cc specific), but I am the author of an eclipse plugin that 
integrates cmake with eclipse CDT and have to parse the build output in order 
to feed the CDT indexer with macro definitions and include paths.

I am asking, because I want to avoid writing parsers that detect the above 
compiler options.

Are there any script generators that produce compiler invocation with the 
above otions? Or tool chains?

TIA,
Martin

Unfortunately this cannot work as with the current generator the

relative path from the CMakeLists.txt file.
So the generated commands are something like

 cd E:/projects/myprojects/final/Debug


If your binary dir resides on a different drive than E:, the generated 
command will not work. Remember, cd on windows does not change the drive.

The generated command should be
cd /D E:/projects...

I think it's a bug.

You can also search for CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT --
you can use that value near the top of your top-level CMakeLists.txt

No, there's no way to tell.

Why do you ask?


My CMakelists.txt changes the value of CMAKE_INSTALL_PREFIX by replacing 
the trailing directory. But it should do this only if the user did not 
specify a value on the commandline.

[CMake] WORKING_DIRECTORY from add_custom_target() not setting current directory on windows

[Martin Weber]

Hi all,

the WORKING_DIRECTORY from add_custom_target() does change the current 
directory properly on windows, if the current directory and the 
directory specified in WORKING_DIRECTORY reside on different drives.

I experienced that with the following command:

add_custom_target(doc
   echo *** CD-ing: cd  ${DOXYGEN_EXECUTABLE} 
${CMAKE_CURRENT_BINARY_DIR}/Doxyfile

WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
COMMENT Generating API documentation VERBATIM
)

which is executed as

[  0%] Generating API documentation
cd D:\develop\ITE\client_automation\src\itecrc-lib  echo *** CD-ing: 
 cd  C:/Program Files (x86)/doxygen/bin/doxygen.exe 
C:/Users/m.weber/Documents/.eclipsews/ITE/client_automation/src/itecrc-lib/Doxyfile

*** CD-ing:
C:\Users\m.weber\Documents\.eclipsews\ITE\client_automation

I expect
D:\develop\ITE\client_automation\src\itecrc-lib
here.
There problem is caused by the cd-command on windows: To change the 
current directory _and_ the drive, the /D option must be specified.

So 'WORKING_DIRECTORY Z://foo' should translate to
'cd /D  Z://foo' on windows to make it work.

Regards,
 Martin
