Here you are the trace I got with gdb (long).
My comments are highlighted with //
Hope this can help.
Apparently, the apr_filepath_merge() method invoked by load_module()
fails during the strlen() evaluation.
Very odd, also because the parameters with the module name and the
relative path for libphp4.so are correct until that point.
Here you have the gdb trace:

Try this configure line: ./configure --disable-all --with-mysql --with-pcre-regex --with-apxs2=/usr/local/apache2/bin/apxs (--disable-all disables every 'by-default' extension) Previous Comments: [2003-02-18 11:53:22] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip [2003-02-18 09:12:56] germano60 at yahoo dot it Hello I already looked in the support resources and in the bug lists but could not find a suitable clue. I compiled apache and php then when I tried to start the web server, but this is the error message I got: Syntax error on line 233 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/libphp4.so into server: Unresolved external The error line did not return any further indications about which external did not resolve. Configuration: hp-ux 11.00 php 4.3.0 apache 2.0.44 gcc 3.2 Apache was generated with: ./configure \ --prefix=/usr/local/apache2 \ --enable-so Php4.3.0 was configured with: ./configure \ --with-mysql \ --with-apxs2=/usr/local/apache2/bin/apxs I modified the configure script for PHP by replacing invokes of -lcrypt with -lc and of -ltermcap with -lcurses to get libphp4.so generated by php's make install under the hp-ux 11 platform. php's make and make install succeeded. DSO modules were installed in the Apache2's default location /usr/local/apache2/modules and this is also where PHP's make install stored the library libphp4.so. In httpd.conf I added the following line: LoadModule php4_module modules/libphp4.so I'm not sure whether this is really a bug or due to my minimal configuration - I tried some of the hints I found in the support/bugs but without success.
