Bug 179271 – Unmerging the active gcc fails

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Pascal Fleury 2007-05-20 20:38:37 UTC]

Unmerging the version of gcc that is currently the active profile (according to gcc-config) fails when trying to scan libtool files for hardcoded paths.

The error is due to the gcc -dumpversion failing in that case.
* Running 'fix_libtool_files.sh 4.1.1'
 * Scanning libtool files for hardcoded gcc library paths...
gcc-config error: Could not run/locate "gcc"
:0: assertion failed: (gcc -dumpversion) | getline NEWVER)
>>> Regenerating /etc/ld.so.cache...


Reproducible: Always

Steps to Reproduce:
1. install gcc 4.1.1-r3 and 4.1.2, set 4.1.1-r3 as the active one with gcc-config
2. emerge --unmerge =gcc-4.1.1-r3



Actual Results:  
At that point, gcc itself is unusable until gcc-config [...]-4.1.2 is used.

Expected Results:  
gcc profile should be set to other one, or at least a better message given.
