Re: [CMake] Fwd: set_target_properties and language specific COMPILE_FLAGS
The solution is to add the POSITION_INDENPENDENT_CODE target property
to the C and Fortran convenience library targets.
Thanks again for the help,

Re: [CMake] Fwd: set_target_properties and language specific COMPILE_FLAGS
Hi Chuck,
I am building both static and shared libraries using the object files.
After splitting the Fortran and C source as you suggest, I get the
following linker error:
/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../x86_64-pc-linux-gnu/bin/ld:
CMakeFiles/spammpack-serial-C.dir/spamm_get_time.c.o: relocation
R_X86_64_32 against `.rodata' can not be used when making a shared
object; recompile with -fPIC
Unfortunately I can't reproduce this error with a smaller test. Should
I pass some additional compiler flags into the OBJECT convenience
library, such as -fPIC as is suggested by the linker? How portable
would that be?
Thanks already,
nick

Hi Chuck,
seems a bit hackish, but works for me :)
Thanks for the trick!

Re: [CMake] Fwd: set_target_properties and language specific COMPILE_FLAGS
Hi Nick,
You could split your target in to two object libraries that combine into a
singe "real" library:
add_library(foo_f OBJECT ${FOO_F_SOURCES})
# set necessary compile flags specific to the Fortran components
# on the foo_f target
add_library(foo_c OBJECT ${FOO_C_SOURCES})
# set necessary compile flags specific to the C components
# on the foo_c target
# Combine into a "real" library
add_library(foo $ $)

[CMake] Fwd: set_target_properties and language specific COMPILE_FLAGS
Hi, I am building a library containing Fortran and C sources. I would like to add language specific compile flags without affecting the global compile flags: set_target_properties( foo PROPERTIES C_FLAGS "-fopenmp" Fortran_FLAGS "-openmp" ) However, it seems there is only COMPILE_FLAGS which presumably affects both languages.
