This bug exists with _ALL_ C compilers we are using. Just simply your recent modifications enabled warnings only for few compilers but many others like all GCC based ones still does not report any warnings so such bugs are invisible. Missing prototypes means that C compiler may incorrectly create function call frame so final code will GPF or fail in other way depending on used ABI and type of parameters. > If the problems won't be resolved, I will simply > disable failing libs for these targets. To fix such problems it's necessary to know about them and this library is yet another example that disabled warnings may cause that we are creating wrong binaries without any knowledge about it. The problem is that nearly all of these libraries uses autoconf to generate configuration header files but we not and we are using in all builds only some statically defined for chosen platform files without real system dependent configuration so such definition can be wrong and broken code is generated. With fully disabled warnings we do not know about it. In this particular case (JPEG library) HAVE_PROTOTYPES definition is missing and it's the reason of above errors in _all_ builds (we do not support any old C compiler which does not support prototypes). best regards, Przemek _______________________________________________ Harbour mailing list (attachment size limit: 40KB) Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
