I'm trying to install PHP 5.1.4 on RedHat(e) Enterprise 3 I'm having a very difficult time getting ./configure to work. Here's what I'm doing so far: [code]./configure --with-apxs2=/usr/local/apache/bin/apxs --disable-cgi --with-config-file-path=/usr/local/apache/php --enable-force-cgi-redirect --disable-short-tags [b]--with-libxml-dir=/usr[/b] --with-openssl --with-zlib --enable-calendar --with-curl --with-mysql --with-mysqli --enable-soap [/code] And this is what I get at the very end: [code] Configuring extensions checking whether to enable LIBXML support... yes checking libxml2 install dir... /usr checking for xml2-config path... /usr/bin/xml2-config checking whether libxml build works... no configure: error: build test failed. Please check the config.log for details. [/code] In config.log I get this: [code]configure:27282: checking whether to enable LIBXML support configure:27320: result: yes configure:27329: checking libxml2 install dir configure:27347: result: /usr configure:27359: checking for xml2-config path configure:27373: result: /usr/bin/xml2-config configure:27516: checking whether libxml build works configure:27549: gcc -o conftest -g -O2 conftest.c -lresolv -lm -ldl -lnsl -lxml2 -lz -lm >&5 /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/../../../libxml2.so: undefined reference to `__memcpy_chk@GLIBC_2.3.4' /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/../../../libxml2.so: undefined reference to `__memmove_chk@GLIBC_2.3.4' /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/../../../libxml2.so: undefined reference to `__vfprintf_chk@GLIBC_2.3.4' /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/../../../libxml2.so: undefined reference to `__fprintf_chk@GLIBC_2.3.4' /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/../../../libxml2.so: undefined reference to `__strcat_chk@GLIBC_2.3.4' /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/../../../libxml2.so: undefined reference to `__snprintf_chk@GLIBC_2.3.4' /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/../../../libxml2.so: undefined reference to `__stack_chk_fail@GLIBC_2.4' /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/../../../libxml2.so: undefined reference to `__vsnprintf_chk@GLIBC_2.3.4' collect2: ld returned 1 exit status [/code] not that I mean to be a complete n00b... but I'm really lost, and I don't understand how to fix this error. Any help you can offer would be fantastic! Thanks to all for the help if I get it! Michael
