Hi Andreas, hi List! I'm not sure what you mean by "have the 32-bit development environment set up" maybe I need some more explanation or a link... I followed your instructions on compiling a 32bit PHP 5.04 executable on a SuSE 9.3 x86_64. (I need to compile a 32bit version because Oracle doesn't provide a 64bit version of the instant client). If I'm compiling only a minimal version everything runs fine and I get Oracle Instant Client support. First I'm executing linux32 bash followed by a export CC='gcc -m32' export LD_LIBRARY_PATH=/opt/instantclient10_1 (for Oracle) This configure/make/make install works well: ./configure \ --prefix=/usr/share/php5 \ --with-config-file-path=/etc/php5 \ --with-oci8-instant-client=/opt/instantclient10_1 \ --enable-fastcgi \ --enable-sigchild \ But as soon as I'm including external libraries I'm running into problems. For example the make for ./configure \ --prefix=/usr/share/php5 \ --with-config-file-path=/etc/php5 \ --with-oci8-instant-client=/opt/instantclient10_1 \ --enable-fastcgi \ --enable-sigchild \ --with-pear=/usr/share/php5/pear \ --enable-soap \ --with-ldap \ --with-openssl \ --enable-calendar \ --enable-mbstring \ returns the following error messages:

Otherwise I might have to install the x86_32 version on the Xeons (because the 32bit compilation works in VMWare fine)... Thanks in advance Reto
