Bug 167

Summary: X_LIBS vs Ubuntu...
Product: SDL Reporter: Ryan C. Gordon <icculus>
Component: videoAssignee: Ryan C. Gordon <icculus>
Status: VERIFIED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: HG 1.2   
Hardware: x86   
OS: Linux   

Description Ryan C. Gordon 2006-03-21 04:15:45 UTC 
The configure script parses the value of $X_LIBS when looking at the --enable-x11-shared, which is getting set on Ubuntu 5.10 to "-L/usr/X11R6/lib" ... however, Ubuntu stores all the Xlib stuff in /usr/lib.

The end result in SDL is that the dynamic X11 stuff gets disabled by default, unless you override like this:

 ./configure --x-libraries=/usr/lib

Is X_LIBS the wrong value to check here, or is Ubuntu's autoconf hosed in this regard? I haven't figured out where this shell variable actually gets set yet...

to be clear, /usr/X11R6/lib DOES exist, but it's got a handful of files/dirs in it:

libxf86config.a  
libXvMCNVIDIA_dynamic.so.1  
modules
libXvMCNVIDIA.a  
libXvMCNVIDIA.so.1.0.8178   
X11


And not things like "libX11.so.6", which are in /usr/lib.

I'm not sure.  X_LIBS is set by the AC_PATH_X and AC_PATH_XTRA macros.

I put a fix into CVS... can you try it out?
