[CMake] RC compiler on Linux
Hi all, I use CMake 2.8.5 on Linux and Windows machine to build a Fortran project. On Windows, no problem, the build and the resulting GUI are OK. On Linux, the build seems to be OK but the resulting GUI gives an empty screen. Discussing with Michael a few days ago made me think that it could be related to the use of an inappropriated motif library. However, looking in more details I see with a make VERBOSE=1 that my rc file is not built (I do not see the line "Building RC object ..."). even if it is declared as one of my sources files. Is there some extra commands to specify to make cmake recognize and compile a rc file ? thanks Eric -- Eric Pellegrini Calcul Scientifique Institut Laue-Langevin Grenoble, France -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
Re: [CMake] RC compiler on Linux - new problem
Hi all, after digging and googling some hours I did a first step in the right direction. I had to add the command: enable_language(rc) set(cmake_rc_compiler_arg1 -cif8) The resource compiler I (must) use is the one provided by winteracter Fortran library. This led me to a serie of problems related to the use of this compiler: - it does not accept any output flag so that the output resource object is always created "in-source" in the rc file directory. - on Linux, it produces a .o object file instead of a .res file Looking at the CMakeRCInformation.cmake I see that by construction CMake will use the following compile command: " /fo " with a resource object file with a .res extension. On a Linux machine, this produces a wrong build command line with the path for the output object file being "/foCMakeFiles/...". This problem was raised sometime ago in the mantis bug tracker but unfortunatley the patch proposed apply for mingw using windres but not for Linux. Is there a fix for this ? If no, is there a way to inform the linker that: - my resource object file is located "in-source" - the extension is not .res but .o thanks for your help Eric pellegrini a écrit : Hi all, I use CMake 2.8.5 on Linux and Windows machine to build a Fortran project.

Re: [CMake] RC compiler on Linux - new problem
Hi Michael, I tried to adapt the files you gave me to my project. It almost works. As a reminder, there were a CMakeLists.txt with an overloaded add_executable function that created a sym_link for the rc files and a shell file (rc.sh) used to suit the rc compiler call to my needs. I found one problem that I still not have solved. The shell script is declared under the following command: set_property(GLOBAL PROPERTY RULE_LAUNCH_COMPILE "bash rc.sh ") However, this command makes that even my f90 files uses the rc compiler which obvioulsy makes my build crash. I tried to use something like set_property(SOURCE myrcfile.rc PROPERTY RULE_LAUNCH_COMPILE ... in order to apply the patch only when a rc file is under process but unfortunately this property is not a valid source properties.

Re: [CMake] RC compiler on Linux - new problem
Hi Michael first of all best wishes for 2012 ! Let's start 2012 with a new question for CMake community ! It is related with prior discussions we had about rc compiler on Linux. Sorry but I had many things to do in the meantime and I could only come back to it recently. As a reminder, my problem was: - I must use the winteracter Fortran library resource compiler - it does not accept any output flag so that the output resource object is always created "in-source" - on Linux, it produces a .o object file instead of a .res file which mess up the rc process of CMake I tried your last suggestion that was to create a wrapper script and use it as the RC when I set the WINTERACTER_RC_COMPILER variable. My CMakeLists.txt file looks now like: ... IF(${WINTERACTER_RC_COMPILER}) CONFIGURE_FILE(winteracter_rc.sh.in winteracter_rc.sh @ONLY) SET(CMAKE_RC_COMPILER winteracter_rc.sh CACHE STRING "RC compiler" FORCE) ENDIF() PROJECT(toto Fortran RC) ... that I build with cmake -G"Unix Makefile" -DWINTERACTER_RC_COMPILER=ON ..\. However, the build ends up with an infinite loop that replicates endlessly the following pattern: -- The Fortran compiler identification is Intel -- Check for working Fortran compiler: /home/cs/pellegrini/bin/ifort -- Check for working Fortran compiler: /home/cs/pellegrini/bin/ifort -- works -- Detecting Fortran compiler ABI info -- Detecting Fortran compiler ABI info - done -- Checking whether /home/cs/pellegrini/bin/ifort supports Fortran 90 -- Checking whether /home/cs/pellegrini/bin/ifort supports Fortran 90 -- yes -- Configuring done You have changed variables that require your cache to be deleted. Configure will be re-run and you may have to reset some variables.

AFAICS, this is because the CMAKE_RC_COMPILER variable mustn't be set to certain values in the cache as they invalidate the latter and make CMake reconfigure the project, thus resulting in the infinite loop. Look at the following exemplary project: CMAKE_MINIMUM_REQUIRED(VERSION 2.8 FATAL_ERROR) PROJECT(RC_LOOP RC) MESSAGE("CMAKE_RC_COMPILER: ${CMAKE_RC_COMPILER}") When configuring with -DCMAKE_RC_COMPILER=/bin/true, everything works fine, but with -DCMAKE_RC_COMPILER=true, the loop occurs although the "true" executable is in the path. This behavior seems a bit faulty to me and doesn't occur with CMAKE_C_COMPILER, e.g., in that manner, but perhaps, a CMake developer can provide us with some enlightenment. As a solution/workaround, you might try a full path for the wrapper script as I have also done in my example, or change the line SET(CMAKE_RC_COMPILER winteracter_rc.sh CACHE STRING "..." FORCE) to SET(ENV{RC} ${CMAKE_BINARY_DIR}/winteracter_rc.sh) preferably also with full path, as the evaluation of the RC environment variable seems to be more robust than CMAKE_RC_COMPILER in this regard. Some additional remarks: (1) The wrapper script is meant to contain a @WINTERACTER_RC_COMPILER@ placeholder, so the CONFIGURE_FILE() command will embed the RC's path, and you shouldn't use WINTERACTER_RC_COMPILER as a boolean variable, but for the path to the actual RC executable. Alternatively, you might do roughly the following: OPTION(WINTERACTER "Use Winteracter tools" ...) IF(WINTERACTER) FIND_PROGRAM(WINTERACTER_RC_COMPILER ...) IF(NOT WINTERACTER_RC_COMPILER) MESSAGE(FATAL_ERROR ...) ENDIF() CONFIGURE_FILE(winteracter_rc.sh.in winteracter_rc.sh @ONLY) SET(ENV{RC} ${CMAKE_BINARY_DIR}/winteracter_rc.sh) ENDIF() PROJECT(... RC) (2) Have you already complaint to the Winteracter people w.r.t. their RC's behavior? ;-) IMO, forcing the output into the same location as the input is hardly acceptable, as source trees might be read- only.
