Help needed tsrm_error

Hello all, I have an issue that I can not seem to resolve. Scenario: Solaris 2.7 Netscape Enterprise Server 4.1 PHP 4.0.4 Oracle 8i Configured as: --enable-debug --enable-pic --enable-inline-optimization --with-regex=system --with-gettext=/usr/bin --enable-safe-mode --enable-sysvmem --enable-sysvshm --enable-track-vars --enable-ftp --with-xml --with-nsapi=/usr/netscape/server4 --with-oracle=/vol01/app/oracle/product/8.1.6 --enable-libgcc The problem occurs when I issue ./start to netscape, I get the following error: conf_init: Error running init function load-modules: dlopen of /usr/netscape/server4/bin/libphp4.so failed (ld.so.1: ns-httpd: fatal: relocation error: file /usr/netscape/server4/bin/libphp4.so: symbol tsrm_error referenced symbol not found) I have tried configuring --with-tsrm-pthreads and I did not get an error when I issue ./start for netscape, however the page with xml code shows up blank in my browser after this happens. I have played around with LD_LIBRARY_PATH trying to find where tsrm_error resides (multiple net searches also) and can not seem to find any useful information. I researched a similar problem and the person that resolved it says that he had to 'add a patch for ZTS and use the --enable-experimental-zts flag'. I tried the --enable-experimental-zts flag with no success. I searched the net for ZTS and could not find a download. Can anyone help? What is tsrm? Thanks in advance, Tony
