Hi everybody, I am trying to build a cross compiler from i686-pc-linux-gnu to powerpc-elf (target platform has no OS). In order to start compiling GNAT for this platform, I would like to pass certain custom system header files and libraries (i.e. my own little C library, whatever is necessary to get GNAT running) to be used when compiling gcc. Specifically, a GNAT cross-compilation asks for <dirent.h> to be present on the target system. (well, that is the first thing, which comes into play when building...) As my target has no file system, I would be fine to just implement a couple of dummy functions for opendir() readdir() and closedir(). How can I tell gcc to use my custom header files and link against the corresponding library functions? Cheers, Andreas PS: I'm currently using the SVN head, if the gcc version does matter.
