Description Peter Dyballa 2006-11-02 15:18:39 UTC 
While making the xserver this now happened:

compiler.h:1430: error: impossible constraint in 'asm'

The file is xserver/hw/xfree86/common/compiler.h, the code is:

1427:	static __inline__ void
1428:	outb(unsigned short port, unsigned char val)
1429:	{
1430:	  __asm__ __volatile__("out%B0 (%1)" : :"a" (val), "d" (port));
1431:	}

plus some more of these! And the building process looked this evening so nice, despite the weather 
outside ...

Mac OS X 10.4.8, PowerPC
GCC 4.0.1
Xorg 7.1.99.2

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.

This seems to be GLX related, too, which is not supported for XDarwin, so it's a faulty bug report. At least, when I build with --disable-glx this error is not reported.
