Hi, when I compiled dragonegg on 64-bit version of Linux I got:

Linking dragonegg.so
/usr/bin/ld: cache.o: relocation R_X86_64_32 against `ggc_free' can not be used
when making a shared object; recompile with -fPIC
cache.o: could not read symbols: Bad value
collect2: ld returned 1 exit status

I wonder if anyone can replicate the issue.

In my case, adding -fPIC to both CLFAGS ans CXXFLAGS fixed the problem.
