I'm trying to install/upgrade the version of PHP we're using on our internal server at work. Doing it from the tarball from php.net and when it comes time to run ./configure I get this error:
checking whether libxml build works... no configure: error: build test failed. Please check the config.log for details.
The config.log has this to say about libxml:
configure:22189: checking whether libxml build works configure:22216: cc -o conftest -g -O2 -fvisibility=hidden conftest.c
-lrt -lm -ldl -lnsl -lxml2 >&5
/usr/lib/gcc/i486-linux-gnu/4.4.6/../../../i386-linux-gnu/libxml2.so: undefined reference >to `gzopen64@ZLIB_220.127.116.11'
I've already tried doing a pretty basic update of libxml from apt and installing specifically zlib 18.104.22.168 from a tarball on http://zlib.net/fossils/ and frankly that's me all out of ideas.
EDIT Solved. Updating to the latest version of zlib rather than using 22.214.171.124 has fixed the issue.
