#50517 [NEW]: --with-libxml-dir too late in EXTRA_LDFLAGS

From: Bjorn dot Wiberg at its dot uu dot se Operating system: IBM AIX 5.3 5300-08-01-0819 PHP version: 5.2.12 PHP Bug Type: Compile Warning Bug description: --with-libxml-dir too late in EXTRA_LDFLAGS Description: ------------ As of PHP 5.2.12, the EXTRA_LDFLAGS line in the Makefile (after running configure) contains the directory pointed to by --with-libxml-dir=/usr/local too late, i.e. after -L/usr/lib, causing the IBM bundled /usr/lib/libxml2.a(libxml2.shr.o) to also be included during linking instead of only /usr/local/lib/libxml2.a(libxml2.so.2). This despite no changes on the configure line since PHP 5.2.11. I just wanted to alert you that this may cause problems (unnecessary dependency problems and probably a version collision between the two XML libraries) for those on IBM AIX. A possible workaround is to specify EXTRA_LDFLAGS=/usr/local/lib ./configure ... so that configure will pick it up and specify it first among the EXTRA_LDFLAGS. Reproduce code: --------------- #! /bin/sh # # Created by configure './configure' \ '--enable-bcmath' \ '--enable-calendar' \ '--enable-cli' \ '--enable-dba' \ '--enable-dbase' \ '--enable-debug' \ '--enable-exif' \ '--enable-embedded-mysqli' \ '--enable-flatfile' \ '--enable-ftp' \ '--enable-gd-jis-conv' \ '--enable-gd-native-ttf' \ '--enable-inifile' \ '--enable-mbstring' \ '--enable-shmop' \ '--enable-soap' \ '--enable-sockets' \ '--enable-sqlite-utf8' \ '--enable-sysvmsg' \ '--enable-sysvsem' \ '--enable-sysvshm' \ '--enable-zip' \ '--enable-zend-multibyte' \ '--prefix=/apache/php' \ '--with-apxs2=/apache/bin/apxs' \ '--with-bz2' \ '--with-cdb' \ '--with-curl' \ '--with-freetype-dir' \ '--with-gd' \ '--with-gdbm' \ '--with-gettext' \ '--with-jpeg-dir' \ '--with-ldap' \ '--with-libxml-dir=/usr/local' \ '--with-mime-magic' \ '--with-mysql=/usr/local/mysql' \ '--with-openssl=/opt/freeware' \ '--with-png-dir' \ '--with-ttf' \ '--with-xmlrpc' \ '--with-xpm-dir' \ '--with-xsl' \ '--with-zlib' \ '--with-zlib-dir' \ "$@" bwiberg@melody-lp04:~$ /usr/local/bin/xml2-config --libs -L/usr/local/lib -lxml2 -lz -lpthread -liconv -lm Expected result: ---------------- No change in EXTRA_LDFLAGS between the versions.
