Re: [CMake] fortran flags in a c++ linked executable

Elena, Try to compile and link by hand. For example - write one CPP, one F90, then compile them with flags you want and link them with flags you want. After you find out, what you need, you may start experimenting with CMake flags. gmake VERBOSE=1 can help you alot to see what is happening

Re: [CMake] fortran flags in a c++ linked executable

Isn't that a compiler flag? You would have to specify that at compile time, not link time. Regards, Arjen On 2009-04-01 01:33, James C. Sutherland wrote: Alin, Thank you for your patience. I now have this set via set( CMAKE_EXE_LINKER_FLAGS -mbig-endian ) However, this does not seem to

[CMake] fortran flags in a c++ linked executable

I am trying to compile a mixed f90/C++ program linked with g++. The fortran compiler flags don't seem to be automatically passed through to the g++ linker. For example, I want to do: set( CMAKE_Fortran_FLAGS -fconvert=big-endian ) When I do this for a fortran program (linked with

Hi, Should not the flag be passed to the linker? So in this case the linker flags are read from the c++ compiler flags? regards, Alin -- __ If the Universities will not study useless subjects, who will?

Re: [CMake] fortran flags in a c++ linked executable

Should not the flag be passed to the linker? So in this case the linker flags are read from the c++ compiler flags? I tried adding add_definitions( ${CMAKE_Fortran_FLAGS} ) But the g++ linker complained about an unrecognized option (the - fconvert=big-endian option). When

Re: [CMake] fortran flags in a c++ linked executable

Alin, Thank you for your patience. I now have this set via set( CMAKE_EXE_LINKER_FLAGS -mbig-endian ) However, this does not seem to affect the reading of the big-endian binary file (which is in read in fortran). Perhaps I am still not setting it properly? James On Mar 31,
