I'm attempting to debug a problem with a ruby module I wrote in C and am receiving a warning from ld which may be causing the segfault. Does anyone know what can cause this warning? .../bin/ld: warning: creating a DT_TEXTREL in object. Jeff.

The resulting make compile is $ make i686-pc-linux-gnu-gcc -fPIC -O2 -pipe -fPIC -I. -I/usr/lib/ruby/1.8/i686-linux -I/usr/lib/ruby/1.8/i686-linux -I. -c Vflow.c i686-pc-linux-gnu-gcc -shared -L'/usr/lib' -Wl,-R'/usr/lib' -o Vflow.so Vflow.o -Wl,-R -Wl,/usr/lib -L/usr/lib -L. -lruby18 -lft -lz -ldl -lcrypt -lm -lc /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5-20050130/../../../../i686-pc- linux-gnu/bin/ld: warning: creating a DT_TEXTREL in object. I'd seen the -FPIC thing in the few web pages I'd manage to find that mentioned this error. Unfortunately this doesn;t seem to fix the problem. I'm scratching my head over this one. gcc, glibc and ld have all been upgraded to the latest. gcc version 3.3.5-20050130 GNU ld version 2.16.1 This is on a gentoo box. I've also got access to a fedora core 5 box and the next chance I get I'll be testing there to see if it's a platform related problem. If anyone has any advise please speak up. Anyway, thanks for the suggestion Guy. Jeff.

This seems to imply that the problem is platform specific. That gentoo (at least in the version I'm running) is only platform that is affected. As I've got no idea what is causing this I'm simple going to avoid it by not running this code on that box. This reply is more for future reference for anyone else that may stubble across this problem than anything else. Jeff.
