Description Kolja Kauder 2003-11-27 11:18:00 UTC

After emerging gcc-3.3.1-r5 with USE="+multilib" many things failed to work, including 
python and therefore env-update and emerge. 
Cause was empty LDPATH in /etc/env.d/05gcc and therefore incomplete ld.so.conf 
Thus programs searched unsuccessfully for libstdc++.so.5 and libgcc_s.so.1 
 

Reproducible: Always
Steps to Reproduce:
1.USE="+multilib" emerge gcc 
2.share and enjoy! 
3. 
Actual Results:  
see Details. 

Expected Results:  
well, work. 

I had previously installed the three emul-linux-x86 packages. 
 
As a workaround I did 
1.	export LD_LIBRARY_PATH=/usr/lib/gcc-lib/x86_64-pc-linux-gnu/3.3.1 
	to get the tools working 
2.	in said directory: 
	ln -s libgcc_s.so.1 libgcc_s.so 
3.	added said PATH in 05gcc 
	LDPATH="/usr/lib/gcc-lib/x86_64-....." 
4.	ran env-update and reboot. 
 
Here's the output of emerge -info AFTER this fix:

you must have gcc-config-1.3.3-r2 or higher installed, you obviously
do not.  The standard gcc-config does not allow multiple paths
in the LDPATH, where as 1.3.3-r2 or higher does.
