[CMake] Nested Project()
Hi, I have several nested directories, and each directory contains a CMakeLists.txt file. And most start with PROJECT( ) Where xxx is some name for what I like to contains some targets. In VC it is possible to create in the top solution, so called solution folders. Why does CMake not use the PROJECT() statement to create such solution folders, in order to group targets? If I remember well, in older versions of Cmake its VC generators, this was like that. I even remember the documentation of PROJECT() did mention it as a special feature for VC in those days. Why is it gone?

[CMake] add_definition??
Hi,
I use ADD_DEFINITIONS( ${wxWidgets_DEFINITIONS} ) to add flags for compilation
like this:
set( wxWidgets_CXX_FLAGS ${wxWidgets_CXX_FLAGS}
-D__WXMSW__ -D__GNUWIN32__ -D__WIN95__
-fexceptions -fno-pcc-struct-return
-fstrict-aliasing
-Wall#all warnings
-Wno-unused-variable
)
Now a user complains that those flags are added to CXX_FLAGS as well as
RC_FLAGS .
The first is right, the second is a problem for the resource compiler windres.exe used in codeblocks
IDE.
What is the right way to set compiler flags for cpp sources and other flags for
the resource compiler?
Or are the generated makefiles not correct??
Thanks,
Klaas

[CMake] N projects/packages that depend
Hi, I have in my repository N projects/packages, that depend on each other. E.g. project 1 found with find_package( wxDocview ), needs to build first, before i can do project2. I can not generate all at once all cmake binary project files, since the project2, call find_package on project 1. Still i like to have an overall CmakeLists.txt file. So i started in that top file with find_package( wxDocview), right after cmake generated the binary stuff for that wxDocview project, on which the second project depends. If the compiled project is not found i tell the user to first make it. But when i type make in project 1, it first runs cmake again, and tells me the again that i should first make it. An that is no good. Well i don't see how to do i :-(. Does someone know how to handle such a situation?

[CMake] Bug in Suffixes windows 2.6

I think this is a bug, only the last version of FIND_PATH actually works.
This is in Cmake 2.6 patch 0.

[CMake] FindFreetype wrong?
Hi,
I want to use FIND_PACKAGE( FREETYPE ) on windows. But it looks like it
does not work.
If i change in FindFreetype.cmake:
FIND_PATH(FREETYPE_INCLUDE_DIR_ft2build ft2build.h
$ENV{FREETYPE_DIR}
NO_DEFAULT_PATH
PATH_SUFFIXES include
)
to this:
FIND_PATH(FREETYPE_INCLUDE_DIR_ft2build ft2build.h
$ENV{FREETYPE_DIR}/include
NO_DEFAULT_PATH
)
It starts working. I tried setting FREETYPE_DIR environment variable
with and without a / at the end, but that is not solving it.
Even setting this:
FIND_PATH(FREETYPE_INCLUDE_DIR_ft2build ft2build.h
c:/soft/freetype/GnuWin32
NO_DEFAULT_PATH
PATH_SUFFIXES include
)
does not work, so i think it is something within Cmake itself. Maybe
something with window paths??
This is with Visual studio 8 + Cmake 2.6 patch 0

Re: [CMake] CMake and Lua
Ken Martin wrote: Which is why CMake has include, macro, foreach etc. which are all staples of a programming language. Right, much better to spend time on something else, and use Lua for all these things. Add wxLua , and the graphical interface becomes easy too. CMakeSetup is nice, but i can't organize options the way i want. So would it be possible to make some hybrid kind of Cmake, which makes it possible to slowly migrate. Or how do you think about using existing modules in Cmake syntax. Maybe calling Cmake macros from a Lua script? How exactly did you wrap in Lua what is there now? Can you mix, or is it just a change or two, and Cmake becomes a lua script? I think to give this a chance, there need to be both at the same time, and slowly migrate modules and projects. Just curious, and like Lua much that i use it as scripting language in my own project, using Cmake to generate the binding and to build it :-) Klaas ___ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
[CMake] linking just static or dynamix no mix.
Hi, My own library, depends on wxWidgets, wxLua, wxstedit. The problem is that i need to link them all static or dynamic, not a mix of them. Now Cmake choosen dynamic above static when available, as i understood. But if for library there is no dynamic version available, this becomes a problem. The linking will be oke, but running the executable, gives errors on two times initializing a static object. Anyway, i like to set a flag too choose what is the preferred manner of linking ( if on search for static libraries first, else prefer dynamic linking). Does such a Cmake variable exist ?

Re: [CMake] IF how?
Hi,
The myvar is the outcome of something like this:
EXEC_PROGRAM( sh
ARGS ${wxWidgets_CONFIG_EXECUTABLE} ${CONFIG_TEST}
--version
OUTPUT_VARIABLE wxWidgets_PFVERSION
RETURN_VALUEwxWidgets_WANTED_AVAILABLE
)
IF ( NOT ${wxWidgets_WANTED_AVAILABLE} STREQUAL 0 )
So it will always be there, i am now doing it like the above.
But i am surprised, that it does not work in a simpler form.
Thanks.

Re: [CMake] how work dependencies
Hi Bill, Working on the test case you asked for, i discovered the problem. Using SET_TARGET_PROPERTIES() i changed the name of the libraries. But also is use TARGET_LINK_LIBRARIES using that real name. I should have used the original target name it seems. Using the real name, dependencies are not discovered, but using the original target used in ADD_LIBRARY() all is fine. You might say of course. But what i did, was put all libraries in a variable, to be used in a template for external user programs to use my libraries in an easy manner. So there one needs the real names of the libraries. While in the samples coming with the libraries one prefers the target names itself, since only then Cmake finds the dependencies. Still it is a bit strange, because using real names, Cmake did not understand to relink a sample, when a library was rebuild. So it knows: - that it links to a library since the real name is in the links list in the VC IDE. - but when that library is out of date, it does not see that, and does not relink. Anyway, i now use target names internal for the samples, and create a variable using real names for external programs. Thanks! Klaas Bill Hoffman wrote: klaas.holwerda wrote: Hi, I always thought that Cmake did automatically rebuild libraries, within the same Cmake build, linked to my application. Like if i have several libraries created with ADD_LIBRARY() and linked to my end executable with TARGET_LINK_LIBARIES or just LINK_LIBRARIES. But it seems i am missing something, since it stopped working for me, and i don't know which change did that. Maybe it is SET_TARGET_PROPERTIES() which i use to set output names for libraries, different from the ones in ADD_LIBRARY its target. So the end executable target, is linked with the endname from the properties, not with the original target name of ADD_LIBRARY. SO the question is, do i need to use: ADD_DEPENDCIES explicit, to make target like the above depend on the other lower targets? Or should this be automatic ( which it was for me before ), and is something else wrong? It should be working. The best thing to try is make VERBOSE=1 and look at the output. Can you create a small test case? -Bill ___ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
Re: [CMake] MSYS + MINGW + wx-config.sh

Hi Klaas,
I don't actually understand your problem correctly. As I understand
you have MSYS, wxWidgets compiled with MSYS and want somehow call
wx-config which is a bash script from the cmake file? Is this correct?
I want to have the output of wx-config, which is a shell script,
installed by wxWidgets in /usr/local/bin.
I am working on a new FindwxWidgets.cmake, to get it working for Mingw
and Msys with some extended features.
# run the wx-config program to get cxxflags
EXEC_PROGRAM(sh
Oke it was in front of me all the time, the sh in the above line is in
fact sh.exe from MSYS. That makes it work more or less.
The RET variable is empty, and the result is oke.
ARGS ${wxWidgets_CONFIG_EXECUTABLE} --cxxflags
OUTPUT_VARIABLE wxWidgets_CXX_FLAGS
RETURN_VALUE RET)
FindwxWidgets.cmake is supposed to work with MSYS. Here wx-config is
called during the cmake configuration process. If this doesn't work,
does FindwxWidgets.cmake work for you in MSYS?
I changed it a bit already, so i now see i did something wrong. Instead of
RESULT_VARIABLE wxWidgets_WANTED_AVAILABLE
it should be
RESULT_VALUE wxWidgets_WANTED_AVAILABLE
No warning from Cmake somehow, but at least i know what to do.
Thanks a lot for pointing me to the problem,

[CMake] wxWidgets Find + Packages macros
Hi Cmakers and users, I did an attempt to improve FindwxWidgets, and to add some macros to easily add packages based on something in the making called wxWidgets Packages. http://wxwpm.sourceforge.net/index.php The packages must be compiled in the same manner as the wxWidgets build that was found, also naming of libraries in a package is based on what was found in the FindwxWidgets stage. Questions: - I am not sure if a FindXX module may contain macros to easily do extra thing with the module found, like finding thirdparty libraries or naming your own libraries on the bases of the module found etc. - Where to best place this (wxWidgets itself or in Cmake ). I did upload it here: http://www.pontademangue.com/tmp/wxpm.tgz It contains the modified FindwxWidgets, a packaged called led + a sample which uses both. I did test it for VC and Linux. Very likely its needs some additional things to deal with MingW or Cygwin, and borland etc. I already did try, but not test it. I am already using it as part of wxArt2D, and it does the job there. Oke, this is just a first step, i am open to all suggestions! Thanks to the original writers of the last version of FindwxWidgets, let me know what i did wrong or where to go next. regards, Klaas ___ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
[CMake] compile header file for precompiled gcc headers
Hi, I want to get gcc to use precompiled headers. From http://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html i read that i need to compile a header file ( containing #includes to all others for instance ). I have this haeder file, how to compile it with Cmake? I tried CHECK_CXX_SOURCE_COMPILES( wxart2d.h DONNO ) But that does not produce a wxart2d.gch file. Understand that i do not need to get an executable nor library. Does somebody know how to do it? Has someone already succeeded in using precompiled headers with gcc on Linux, any tips?
