[CMake] making executible in mixed C/fortran project
Greetings, I am learning cmake I am building an executable which needs to first compile a C program and then recompiling the object file with another file in fortran. Here is an excerpt from a unix makefile I am attempt to port to cmake as part of my cmake turotial. fileC.o: fileC.c $(C) -DDINT -c fileC.c fileD: fileD.f fileC.o ../lib/libF.a $(F77) $(F77FLAGS) -o fileD fileD.f fileC.o../lib/libF.a $(F77LIB) I think I have learnt enough cmake to do most of the above EXCEPT I am unsure how on compile an object file (in this case fileC.o with a fortran compiler (if I have translated the makefile correctly) Does one rename the file or whatever? Guidance on how to do this would be appreciated ___ 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

I am building an executable which needs to first compile a C program

Here is an excerpt from a unix makefile I am attempt to port to cmake as
part of my cmake turotial.
fileC.o: fileC.c
$(C) -DDINT -c fileC.c
fileD: fileD.f fileC.o ../lib/libF.a
$(F77) $(F77FLAGS) -o fileD fileD.f fileC.o../lib/libF.a $(F77LIB)
I think I have learnt enough cmake to do most of the above EXCEPT I am
unsure how on compile an object file (in this case fileC.o
with a fortran compiler (if I have translated the makefile correctly)
Does one rename the file or whatever?
Guidance on how to do this would be appreciated
You might try
ADD_LIBRARY(C STATIC fileC.c)
in junction with
TARGET_LINK_LIBRARIES(fileD C ...)
It would not go in the loop
add_executable(fileD
fileD.f
ADD_LIBRARY(fileC STATIC fileC.c )
${fileC} )
so I tried it outside like so:-
SET_SOURCE_FILES_PROPERTIES( fileC.c PROPERTIES COMPILE_DEFINITIONS DINT )
ADD_LIBRARY(fileC STATIC fileC.c )
add_executable(fileD
fileD.f
${fileC} )
target_link_libraries(fileD $(F77LIB) )
---but make ends like so:-
CMakeFiles/filedD.dir/filedD.f.o: In function `MAIN__':
filedD.f:(.text+0x2f9): undefined reference to `Ddefaults_'
filedD.f:(.text+0x32b): undefined reference to `Dorder_'
filedD.f:(.text+0x33a): undefined reference to `Dinfo_'
collect2: ld returned 1 exit status
---
oher suggestions welcomed
since you shouldn't directly refer to object files with CMake.

You might try
ADD_LIBRARY(C STATIC fileC.c)
in junction with
TARGET_LINK_LIBRARIES(fileD C ...)
It would not go in the loop
add_executable(fileD
fileD.f
ADD_LIBRARY(fileC STATIC fileC.c )
${fileC} )
Which loop are you talking about, and which value does the fileC
variable has here? Moreover, the ADD_LIBRARY() command must not
appear among the source files of ADD_EXECUTABLE(), of course.
so I tried it outside like so:-
SET_SOURCE_FILES_PROPERTIES( fileC.c PROPERTIES COMPILE_DEFINITIONS DINT )
ADD_LIBRARY(fileC STATIC fileC.c )
add_executable(fileD
fileD.f
${fileC} )
target_link_libraries(fileD $(F77LIB) )
That's better, but you need to mention the fileC library target in
TARGET_LINK_LIBRARIES() for this to work, and again: What's the value
of the fileC variable here? Note that you've an equally named target.
If you don't really intent to re-use fileC.c, but just want to mix it
with the Fortran sources of fileD, you can do so, i.e. you might say
ADD_EXECUTABLE(fileD fileD.f fileC.c)
but when mixing several languages read about the LINKER_LANGUAGE
target property as well as the CMAKE_LANG_LINKER_PREFERENCE
and CMAKE_LANG_LINKER_PREFERENCE_PROPAGATES variables.
---but make ends like so:-
CMakeFiles/filedD.dir/filedD.f.o: In function `MAIN__':
filedD.f:(.text+0x2f9): undefined reference to `Ddefaults_'
filedD.f:(.text+0x32b): undefined reference to `Dorder_'
filedD.f:(.text+0x33a): undefined reference to `Dinfo_'
collect2: ld returned 1 exit status
Usually, that means there are missing sources in ADD_EXECUTABLE() or
missing libraries in TARGET_LINK_LIBRARIES(); perhaps, you can post
a complete but minimal example as a demonstration of this issue.
