• Status: RESOLVED FIXED
• Product: Gentoo/Alt

Compiling ruby with USE=threads fails on solaris 10 with the following message:
i386-pc-solaris2.10-gcc -shared -o ../../.ext/i386-solaris2.10/bigdecimal.so bigdecimal.o -L. -L../.. -L.  -Wl,-E    -Wl,-R -Wl,/nilfisk/home/dve/gentoo-new/usr/lib -L/nilfisk/home/dve/gentoo-new/usr/lib -lruby18  -lpthread -lrt -ldl -lcrypt -lm   -lc

../../libruby18.so: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[1]: *** [../../.ext/i386-solaris2.10/bigdecimal.so] Error 1

compiling with USE="-threads" works fine

can you try if manually replacing -lpthread with -pthread solves the issue?

[Comment 2 Daniel Vergien 2010-02-28 10:05:53 UTC]

I changed -lpthread in the Makefiles and rbconfig.rb to -pthread and then it compiles fine.

[Comment 3 Fabian Groffen 2010-02-28 12:35:16 UTC]

I fixed this a bit hacky in the configure script by relying on GCC's -pthread unconditionally.
