Hi All,We build on an IBM AIX system with the VisualAge compilers. We have some Fortran code that depends on being preprocessed by the C preprocessor. Like most Fortran compilers, IBM's Fortran compiler automatically runs cpp on *.F files.
It appears that add_definitions() places -DWHATEVER in the compile command line on all Unix variants. Unfortunately, IBM's Fortran compiler uses -D as a compile flag for something other than adding a preprocessor definition. In order to pass a preprocessor definition, you have to use -WF,-DWHATEVER. So, if you call add_definitions() anywhere in the tree above a Fortran target, you end up with a compile error since CMake adds -D to the compile line and IBM expects this to mean something else.
I'm trying to figure out the best way to deal with this problem, and whether or not this is a bug in CMake's implementation on VisualAge compilers.
Does anyone have a suggestion? If it is a bug, is there a workaround that we can use in the interim? Also, if it is a bug, what would be involved in fixing it, and is there any way we can assist in either fixing it or testing a possible fix?
