Description Jozef Behran 2005-06-14 14:30:30 UTC

After you try to emerge different 

Reproducible: Always
Steps to Reproduce:
1. Emerge gcc-3.4.4*  
2. Emerge gcc-3.4.3*  
3. Try to use portage or anything using libstdc++ 
Actual Results:  
# emerge --update world 
/usr/bin/python: error while loading shared libraries: libstdc++.so.6: cannot open 
shared object file: No such file or directory 
 

Expected Results:  
Things should work as before 

The point where things screw up is here:   
   
   ... 
   
 * The current gcc config appears valid, so it will not be   
 * automatically switched for you.  If you would like to   
 * switch to the newly installed gcc version, do the   
 * following:   
   
 * gcc-config i686-pc-linux-gnu-3.4.3   
 * source /etc/profile   
   
   
 * If you have issues with packages unable to locate libstdc++.la,   
 * then try running 'fix_libtool_files.sh' on the old gcc versions.

   ...   
   
The problem with this is that the current configuration is *-gcc-3.4.4-*, which is 
immediately broken down by the following unmerge operation.

Missing detailed description: 
 
After you try to emerge different version of GCC, almost everything stops working
