Compile - libxml2

I've opened a bug report on bug.php.net, Compiling PHP in 5.2.2 is working with my libxml2, but not in 5.2.4 (and 5.2.5) but developpers say me that's not a bug : I must use XML2_DIR instead of XML_DIR, But when using configure, it say me : use libxml-dir for libxml2 using libxml2-dir is not working, in 5.2.2 and 5.2.4 using libxml-dir is working in 5.2.2 but no 5.2.4 libxml2-dir isn't an existing variable in the configuration script. Best regards, http://bugs.php.net/bug.php?id=43212 Description: ------------ Compilation work with PHP 5.2.2 but not 5.2.4 In 5.2.2 : checking libxml2 install dir... checking for xml2-config path... (cached) /opt/freeware/libxml2/libxml2/bin/xml2-config checking whether libxml build works... (cached) yes In 5.2.4 : checking for xml2-config path... configure: error: xml2-config not found. Please check your libxml2 installation. My xml2-config is in /opt/freeware/libxml2/2.6.30/bin Reproduce code: --------------- inudupb@R2$ more .envcommun LADATE=$(date +%Y%m%d%H%M) PATH=/opt/freeware/gcc/gcc/bin:${PATH} export PATH ZLIB_VERSION=1.2.3 CURL_VERSION=7.17.1 MYSQL_VERSION=4.1.18 OPENSSL_VERSION=0.9.8g OPENLDAP_VERSION=2.3.39 APACHE_VERSION=2.0.61 FREETYPE_VERSION=2.3.5 GD_VERSION=2.0.35 JPEG_VERSION=6b PNG_VERSION=1.2.22 XML_VERSION=2.6.30 PHP_VERSION=5.2.2 ZLIB_DIR=/opt/freeware/zlib/${ZLIB_VERSION} CURL_DIR=/opt/freeware/curl/${CURL_VERSION} MYSQL_DIR=/ibp/uti/msq/${MYSQL_VERSION} OPENSSL_DIR=/opt/freeware/openssl/${OPENSSL_VERSION} OPENLDAP_DIR=/opt/freeware/openldap/${OPENLDAP_VERSION} APACHE_DIR=/opt/freeware/apache/${APACHE_VERSION} FREETYPE_DIR=/opt/freeware/freetype2/${FREETYPE_VERSION} GD_DIR=/opt/freeware/gd/${GD_VERSION} JPEG_DIR=/opt/freeware/jpeg/${JPEG_VERSION} PNG_DIR=/opt/freeware/libpng/${PNG_VERSION} XML_DIR=/opt/freeware/libxml2/${XML_VERSION} PHP_DIR=/ibp/uti/php/${PHP_VERSION} DATADIRECT_DIR=/ibp/uti/ddt/datadirect ##### cd php-${PHP_VERSION} LDFLAGS="-L${FREETYPE_DIR}/lib" CPPFLAGS="-I${DATADIRECT_DIR}/include -I${FREETYPE_DIR}/include" CUSTOM_ODBC_LIBS="-L${DATADIRECT_DIR}/lib -lodbc -lodbcinst" PATH=/opt/freeware/freetype2/freetype2/bin:${PATH} export LDFLAGS CPPFLAGS CUSTOM_ODBC_LIBS PATH make clean ../configure \ --prefix=${PHP_DIR} \ --with-config-file-path=${PHP_DIR} \ --with-apxs2=${APACHE_DIR}/bin/apxs \ --enable-safe-mode \ --enable-mbstring=all \ --enable-mbstr-enc-trans \ --enable-mbregex \ --disable-ipv6 \ --enable-libgcc \ --with-openssl=shared,${OPENSSL_DIR} \ --with-openssl-dir=${OPENSSL_DIR} \ --with-zlib=shared,${ZLIB_DIR} \ --with-zlib-dir=${ZLIB_DIR} \ --with-ldap=shared,${OPENLDAP_DIR} \ --with-libxml-dir=${XML2_DIR} \ --with-custom-odbc=${DATADIRECT_DIR} \ --enable-simplexml \ --enable-bcmath \ --enable-calendar=shared \ --enable-ctype \ --enable-tokenizer \ --enable-session \ --with-ldap=${OPENLDAP_DIR} \ --with-curl=${CURL_DIR} \ --with-mysql=${MYSQL_DIR} \ --with-mysqli=${MYSQL_DIR}/bin/mysql_config \ --enable-ftp \ --with-jpeg-dir=${JPEG_DIR} \ --with-png-dir=${PNG_DIR} \ --with-gd=shared \ --enable-gd-native-ttf \ --with-freetype-dir=${FREETYPE_DIR}
