Hello, A cross-compile toolchain that I use just refuses to compile any code that uses fork() because uClinux uses vfork() instead: "undefined reference to `_fork'" However, some applications use if/else blocks just as this one instead of eg. "#ifdef HAVE_FOR" conditional compiling: ============ if (uClinux) { *pid = vfork(); } else { *pid = fork(); } ============ Is it possible to modify configure.ac so that it goes ahead and compiles applications that handle fork/vfork without preprocessor commands? Thank you. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
