Re: XFree86 4.0 and XEmacs-21.2's configure

Vin> I recently installed XFree86-4.01 (from a contributed Mandrake RPM), Vin> and I found I could not configure 21.2 from the CVS sources, because Vin> configure detects that: Vin> #define _XOPEN_SOURCE 500 Vin> should be defined in confdefs.h, and xmkmf has the following defines: Vin> -D_POSIX_SOURCE -D_XOPEN_SOURCE Vin> this causes confdefs.h to have both: Vin> #define _XOPEN_SOURCE 500 Vin> ...

Shouldn't everything just work albeit with warnings every compile? Vin> I have worked around the problem for the moment by changing the Vin> definition in xmkmf to -D_XOPEN_SOURCE=500, but this problem probably Vin> needs to be fixed. Martin, what's the best way to fix this? I'm not sure. The easiest fix is to explicitly exclude XOPEN_SOURCE from the list of symbols controlled by xmkmf. Or change any #define-ition of _XOPEN_SOURCE to #define _XOPEN_SOURCE 500 (this value was chosen by me because X/Open recommends it!). Unfortunately, we can't explicitly #undef _XOPEN_SOURCE in config.h before defining it. It has long been my opinion that xmkmf has no business defining symbols like _XOPEN_SOURCE and _BSD, etc... Those symbols are assertions about the APPLICATION's source code. I will get xfree86 4.0.1 and try to build XEmacs with it. Martin
