PHP and Informix installation

Hi, I installed php y my UNIX SCO Openserver and it works fine. Now, in the same server is installed the Informix Online 5.10. I want to access the Informix databases then I run the next commands successfully: cd php-4.0.6 ./configure --with-apache=../apache_1.3.20 --enable-track-vars --with-informix=/usr/informix make make install cd ../apache_1.3.20 ./configure --prefix=/usr/internet/apache --activate-module=src/modules/php4/libphp4.a All is OK until the last command (./configure ...) I get the error messages: # ./configure --prefix=/usr/internet/apache --activate-module=src/modules/php4/libphp4.a Configuring for Apache, Version 1.3.20 + using installation path layout: Apache (config.layout) + activated php4 module (modules/php4/libphp4.a) Creating Makefile Creating Configuration.apaci in src Creating Makefile in src + configured for SCO 5 platform + setting C compiler to gcc + setting C pre-processor to gcc -E + checking for system header files + adding selected modules o php4_module uses ConfigStart/End + checking sizeof various data types + doing sanity check on compiler and options ** A test compilation with your Makefile configuration ** failed.

Looks like the library libifos.so is wrong, does anyone have an idea what's going on? Thanks in advance. Marco Muciño
