Hello, Sorry if this question is too general. I maintain two cross-platform programs (tuxmath and tuxtype), which are being refactored to use a common library, t4k_common. Both programs use autoconf to test for the presence of scandir and alphasort, and conditionally compile replacements as needed. I'd like to move this "replacement function" code into the common library. From the standpoint of the game program itself, e.g. tuxmath, it would be simplest for the library's header file to have the prototypes of the replacement functions be conditionally present, e.g.: t4k_common.h: ............ #include "config.h" #ifndef HAVE_SCANDIR int scandir(/* args -- */); #endif But of course having #include "config.h" in the interface header will collide with tuxmath's config.h, so we can't do that. I found an autoconf macro (ax_config_prefix.m4, iirc), apparently written with this purpose in mind, that renames config.h and adds prefixes to all the preprocessor macros, but it caused NLS to break, so I removed it. I then reasoned that I could put the scandir() prototype into its own header, t4k_scandir.h, and conditionally include that within tuxmath: tuxmath's globals.h: --------- -#include "config.h" #ifndef HAVE_SCANDIR #include <t4k_scandir.h> #endif But that doesn't work either, because tuxmath's configure finds the scandir in t4k_common, even if the underlying platform lacks it. So - is it possible to have a secondary configuration header similar to config.h that only includes results of checks for scandir and alphasort, with modified names so I can safely include it in t4k_common.h? e.g.: t4k_common.h: ............ #include "config_repl.h" #ifndef HAVE_PLATFORM_SCANDIR int scandir(/* args -- */); #endif Then tuxmath and tuxtype could simply include t4k_common and not worry about where scandir is coming from. Perhaps there is a simpler and officially-recommended way to do this, but I haven't been able to find it.
