Hi,
I am having a bit of trouble compiling openbabel-2.2.3 from source
on 64bit CentOS 5. The compilation fails at the linking stage with:
make[2]: Entering directory `/usr/local/src/openbabel-2.2.3/test'
/bin/sh ../libtool --tag=CXX --mode=link g++ -g -O2 -o roundtrip
roundtrip.o ../src/libopenbabel.la -ldl -lz -lm
libtool: link: g++ -g -O2 -o .libs/roundtrip roundtrip.o

>From other sources, I think this is because the compilation is picking up
conflicting zlib installations. I have 32 and 64 bit zlib libraries
installed:
# rpm -qa | grep zlib
zlib-1.2.3-3
zlib-1.2.3-3
zlib-devel-1.2.3-3
zlib-devel-1.2.3-3
but also installed EMBOSS from source which installs its own zlib headers
and libraries in /usr/local/include and /usr/local/lib, which is where the
e... versions of the zlib functions are coming from. What I don't quite
get is why openbabel is picking up these libraries at all the e...
definitions are in /usr/local/include/zlibemboss.h and the EMBOSS zlib
library is /usr/local/lib/libezlib*, so why should they ever be found by
openbabel?
Thanks in advance for any suggestions.
