Bug 97254 – sablotron 1.0.0 doesn't build with CXXFLAGS = -fvisibility=hidden

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Michael Ditum 2005-06-27 13:44:35 UTC]

Building sablotron 1.0.0 with gcc 3.4.1 with your CXXFLAGS containing
-fvisibility=hidden fails to compile with the following output...
g++ -O3 -pipe -ffast-math -march=pentium4 -fomit-frame-pointer -mfpmath=sse
-msse2 -mmmx -fvisibility=hidden -fvisibility-inlines-hidden -o .libs/sabcmd

!!! ERROR: app-text/sablotron-1.0 failed.

If I modify the ebuild to specify my CXXFLAGS without the -fvisibility=hidden it
compiled fine... this seems to be the same type of bug as bug 31325 (which
claims it has been fixed but hasn't). I would have posted a patch but I couldn't
get filter-flags to work correctly...

Reproducible: Always
Steps to Reproduce:
1. Install gcc 3.4.1 and add -fvisibilty=hidden to your CXXFLAGS 
2. emerge sablotron
3. wait...

Actual Results:  
compilation fails with the above error message.

Expected Results:  
completed installation

sorry being stupid I mean its the same type as bug 77033

This bug is INVALID. You should never put -fvisibility=hidden in your
CFLAGS/CXXFLAGS since it will break anything that builds shared libs and isn't
specially designed to use it. It's purely for developers.

yeah, dont screw around with -fvisibility in your CFLAGS
