Bug 78560 – libtool .la files retain inconsistent libstdc++ reference after gcc upgrade

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Jordan Ritter 2005-01-18 12:22:47 UTC]

Some of the individual libtool *.la files generated (when each libtoolized library is compiled and installed) contain ``dependency_libs'' values that reference version-specific gcc/g++ .la files (specifically, the libstdc++.la file).  

When the toolchain undergoes a version upgrade (3.3.4 to 3.3.5, for instance), these .la files are not updated and thus subsequent compiles of dependent packages fail because their libtool automatically includes their library dependencies' .la files that themselves reference non-existent libtool files (in this case, /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.4/libstdc++.la).

It is not clear whether this is a bug in manually-included-libtool projects or in the methodology of the .la files, or something else entirely.

To fix this quickly I ran:

for file in /lib/*.la /usr/lib/*.la /usr/kde/3.3/lib/*.la; do perl -pe 's/3.3.4/3.3.5/g' $file > $file.tmp && mv $file.tmp $file; done

Alternatively, a more thorough (but time consuming and burdensome) solution is to recompile all dependencies of the failed package (which in turn updates the relevant .la files with proper paths).  

Reproducible: Always
Steps to Reproduce:
1. emerge gcc major version X (e.g. sys-devel/gcc-3.3.4-r2)
2. build libtool-dependent library(s) that depends on libstdc++ (something that generates a .la when installed, e.g. media-video/avifile-0.7.41.20041001-r1)
3. build libtool-dependent program(s) that depend on the library(s) from 2 (e.g. app-cdr/k3b-0.11.17)
4. upgrade gcc to a new major version Y (e.g. sys-devel/gcc-3.3.5-r1)
5. upgrade(or rebuild?) program(s) dependent on library(s) from 2 (e.g. app-cdr/k3b-0.11.18)


Actual Results:  
emerge of k3b failed due to missing link file (/usr/lib/gcc-lib/i686-pc-linux-
gnu/3.3.4/libstdc++.la)

Expected Results:  
emerge should have completed successfully
