Bug 289208 – dev-php5/xdebug-2.0.3 build fails with -fPIC error

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Walter 2009-10-15 14:14:11 UTC]

When rebuilding dev-php5/xdebug-2.0.3 on amd64 against dev-lang/php-5.2.11 the compilation fails with an -fPIC error.

I was rebuilding both PHP and xdebug/other extensions in order to try to work around an issue I was having with PHP saying 'dynamic modules not supported on this platform' and failing to load some required modules (geoip, etc.)

Reproducible: Always

Steps to Reproduce:
On an amd64 machine, run...
1. emerge =dev-lang/php-5.2.11
2. emerge =dev-php5/xdebug-2.0.3
Actual Results:  
Build fails with...
/mnt/newdisk/usr/x86_64-pc-linux-gnu/gcc-bin/4.1.2/../../../lib/gcc/x86_64-pc-linux-gnu/4.1.2/../../../../x86_64-pc-linux-gnu/bin/ld: /mnt/newdisk/usr/x86_64-pc-linux-gnu/gcc-bin/4.1.2/../../../lib/gcc/x86_64-pc-linux-gnu/4.1.2/../../../../lib64/libm.a(s_ceil.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC
/mnt/newdisk/usr/x86_64-pc-linux-gnu/gcc-bin/4.1.2/../../../lib/gcc/x86_64-pc-linux-gnu/4.1.2/../../../../lib64/libm.a: could not read symbols: Bad value
collect2: ld returned 1 exit status


Expected Results:  
Package installs correctly.

The system is a VM under VMWare.  The /mnt/newdisk/usr stuff is just a prefix to the 'real' location of /usr, which is a symlink over there.  Basically I had to add a new disk to compensate for underestimating the eventual disk needs of the VM.

Please attach your full build log from failed compile of xdebug. Also, if you happen to have an old build log from when you succeeded in compiling xdebug before this attempt, that could be useful too.
