GNU Info (g77-295.info)Directory OptionsOptions for Directory Search ============================ These options affect how the `cpp' preprocessor searches for files specified via the `#include' directive. Therefore, when compiling Fortran programs, they are meaningful when the preprocessor is used. Some of these options also affect how `g77' searches for files specified via the `INCLUDE' directive, although files included by that directive are not, themselves, preprocessed. These options are: `-I-' `-IDIR' These affect interpretation of the `INCLUDE' directive (as well as of the `#include' directive of the `cpp' preprocessor). Note that `-IDIR' must be specified *without* any spaces between `-I' and the directory name--that is, `-Ifoo/bar' is valid, but `-I foo/bar' is rejected by the `g77' compiler (though the preprocessor supports the latter form). Also note that the general behavior of `-I' and `INCLUDE' is pretty much the same as of `-I' with `#include' in the `cpp' preprocessor, with regard to looking for `header.gcc' files and other such things.
