PHP 4.0 Bug #8575: && [PHP-INST] PHP 4.0.4 - unable to configure under Solaris 2.6 (explanation)

Introduction: OK, so you don't believe PHP 4.0.4 configure fails under Solaris 2.6? :-) Ju st read on. You'll get known how it is possible at all. Below you'll find th e complete history as well as the description what was going on and why it f ailed (even two times). Summary: there are at least 2 problems with PHP configure. These problems prevent con figure from correctly completing in certain circumstances. History: 1. zlib 1.1.3 was installed: # cd /usr/local/lib # ls -l libz.a -rwxr-xr-x 1 root other 71276 Oct 21 18:30 libz.a 2. mysql-3.23.27-beta was installed: # cd /usr/local/lib/mysql # ls -l libmysqlclient* -rwxr-xr-x 1 root other 186824 Nov 23 19:14 libmysqlclient.a -rwxr-xr-x 1 root other 730 Nov 23 19:14 libmysqlclient.la lrwxrwxrwx 1 root other 24 Nov 23 19:14 libmysqlclient.so -> l ibmysqlclient.so.10.0.0 lrwxrwxrwx 1 root other 24 Nov 23 19:14 libmysqlclient.so.10 - > libmysqlclient.so.10.0.0 -rwxr-xr-x 1 root other 135916 Nov 23 19:14 libmysqlclient.so.10.0 .0 3. we can make two remarks here: -- both MySQL client object and shared object libraries were installed -- MySQL was installed with support for compressed communication protocol (s ee MySQL manual - 4.12.1), so MySQL client libraries contain references to c ompress and uncompress. MySQL installation was succesful - it was -lz used t here. 4. then PHP 4.0.4 was attempted to be configured: ./configure --with-zlib --with-mysql=/usr/local --with-apache=../../apache/a pache_1.3.12 --with-ldap=/usr/local/ldap --enable-track-vars --enable-magic- quotes --enable-bcmath 5. configure failed while checking for gzgets(). This is described as bug #8 575. The problem was remedied with manually changing library order in config ure script (from: -lz -lmysqlclient to: -lmysqlclient -lz) 6. configure failed once more while checking for seteuid(). This was describ ed in previous post to PHP-INSTALL. The debug log shows (among others): gcc -o conftest -g -O2 -D_POSIX_PTHREAD_SEMANTICS -R/usr/ucblib -L/usr/ucb lib -R/usr/local/lib/gcc-lib/sparc-sun-solaris2.6/2.95.2 -L/usr/local/lib/gcc-li b/sp arc-sun-solaris2.6/2.95.2 -R/usr/local/ldap/lib -L/usr/local/ldap/lib -R/usr /loc al/lib/mysql -L/usr/local/lib/mysql conftest.c -lmysqlclient -lldap -llber - lres olv -lresolv -lm -ldl -lcrypt -lnsl -lsocket -lsocket -lgcc 1>&5 Undefined first referenced symbol in file uncompress /usr/local/lib/mysql/libmysqlclient.so compress /usr/local/lib/mysql/libmysqlclient.so ld: fatal: Symbol referencing errors. No output written to conftest 7. what we can see is: -- while checking for seteuid() (and more) and gzgets(), PHP configure does this check without -B static option. This is a reason why we see undefined s ymbols in *.so libraries -- while checking for gzgets(), PHP configure uses incorrect order of librar ies, so reference to compress and uncompress from libmysqlclient can not be resolved. -- while checking for seteuid(), PHP configure completely misses -lz (rest a s above). Alternatively, a question is: why all libraries are included while checking for basic system calls? If additional libraries were not checked, n o problem would arise. Conclusion: PHP configure fix is needed. I'll happily test it, just please provide data. Thank you for your attention. Maciek Uhlig Computer Center, University of Silesia, Katowice, Poland
