For some reason, a very bad decision was made to force linking against /usr/lib: configure:2846: gcc -o conftest -g -O2 conftest.c -R /usr/lib 1>&5 /usr/lib: file not recognized: Is a directory configure:2879: gcc -o conftest -g -O2 conftest.c -Wl,-rpath,/usr/lib 1>&5 configure:46629: gcc -o conftest -I/usr/include -g -O2 -L/usr/lib -Wl,-rpath,/opt/zimbra/libxml2-2.6.32.1/lib -L/opt/zimbra/libxml2-2.6.32.1/lib conftest.c -lrt -lresolv -lm -ldl -lnsl - lxml2 -lz -lm -lxml2 -lz -lm 1>&5 configure:46901: gcc -o conftest -I/usr/include -g -O2 -L/usr/lib -Wl,-rpath,/opt/zimbra/libxml2-2.6.32.1/lib -L/opt/zimbra/libxml2-2.6.32.1/lib conftest.c -lrt -lresolv -lm -ldl -lnsl - lxml2 -lz -lm -lxml2 -lz -lm 1>&5 Which of course overrides custom locations. SEe how -L/usr/lib is used all over the place. The reason I don't see it as an issue on 64 bit RHEL systems is because the libs are in /usr/lib64. ------------------------------------------------------------------------ [2010-01-08 18:07:28] quanah at zimbra dot com Description: ------------ I build PHP against my own build of libxml2. However, starting with PHP 5.2.12, it now links against the system xml2 in addition to my xml2, causing symbol failures: # Libraries that this one depends upon. dependency_libs=' -lcrypt -lcrypt -lrt -lrt -lm -lz -lm -lz -lm -lz -lm -lcrypt -lz -lm -lz -lm -lz -lm -lcrypt -L/usr/lib -L/opt/zimbra/libxml2-2.6.32.1/lib -L/opt/zimbra/aspell-0.60.6/lib -lcrypt -lcrypt /opt/zimbra/aspell-0.60.6/lib/libpspell.la /opt/zimbra/aspell-0.60.6/lib/libaspell.la -lrt -lrt -lresolv -lm -ldl -lnsl -lz -lm -lz -lm -lz -lm -lcrypt -lz -lm -lz -lm /usr/lib/libxml2.la -lpthread -lz -lm -lz -lm -lcrypt' [build@build01 .libs]$ ldd libphp5.so <snip> libxml2.so.2 => /usr/lib/libxml2.so.2 (0x00157000) </snip> Note my libxml2 is a static library.
