This file must be translated to C and modified to build everywhere.
Run flex like this:
flex --prefix=cmDependsFortran_yy --header-file=cmDependsFortranLexer.h -ocmDependsFortranLexer.c cmDependsFortranLexer.in.l
Modify cmDependsFortranLexer.c:
- remove TABs
- add a statement "(void)yyscanner;" to the top of these methods:
yy_fatal_error, yyalloc, yyrealloc, yyfree
- remove all YY_BREAK lines occurring right after return statements
Modify cmDependsFortranLexer.h:
- remove TABs
- remove the yy_init_globals function
- add these lines around all function declarations:
#ifdef __cplusplus
extern "C"
{
#endif
...
#ifdef __cplusplus
}
#endif
- remove the block that includes unistd.h
