note 9454 added to Installation on UNIX systems

Unless you have magical powers (or maybe you just have a clue about these things) you will be unable to compile PHP (4.0.3pl1) as a DSO for Apache on HP-UX (11). You will get the following error when running make install: ---------------------------------------- *** Warning: inter-library dependencies are not known to be supported. *** All declared inter-library dependencies are being dropped. *** The inter-library dependencies that have been dropped here will be *** automatically added whenever a program is linked with this library *** or is declared to -dlopen it. /opt/apache/bin/apxs -i -a -n php4 libs/libphp4.sl apxs:Error: file libs/libphp4.sl is not a DSO *** Error exit code 1 Stop. *** Error exit code 1 Stop. ---------------------------------------- I was only able to install PHP must as a static module, and only after doing the following: 1. Install GCC (I could not get HP ANSI C to compile it) 2. Install Gnu binutils 3. Modify the zend_extension_startup function defined in the Zend/zend_extensions.c file (preprocessor definitions added): ---------------------------------------- static void zend_extension_startup(zend_extension *extension) { #if ZEND_EXTENSIONS_SUPPORT /* this line added */ if(extension->startup) { if(extension->startup(extension)!=SUCCESS) { DL_UNLOAD(extension->handle) } } #endif /* this line added */ } ---------------------------------------- Without adding these preprocessor lines you will get the following error when running make install on Apache (after PHP is already built): ---------------------------------------- /usr/ccs/bin/ld: Unsatisfied symbols: DL_UNLOAD (code) collect2: ld returned 1 exit status *** Error exit code 1 Stop. *** Error exit code 1 Stop. *** Error exit code 1 Stop. ---------------------------------------- Thanks to Lutz Jaenicke (Lutz.Jaenicke@iee.TU-Berlin.DE) for this information, who also reports that a bug report has been filed for this. http://www.php.net/manual/install.unix.php
