knowledgebase/linux/miscapplications/Build php 5.1.6 rpm on RHEL4 Some customers want to use apache2.2+php5 but they do not want to upgrade their RHEL4/CentOS4. According to customers' requirements, we can grab SRPMs from CentOS 5 beta and build binary RPMs on RHEL4/CentOS4. Most likely we should get srpm of apr, apr-util, pcre, httpd and php {code:none} [root@happyrimu ~]# ls apr-1.2.7-10.src.rpm httpd-2.2.3-5.el5.centos.1.src.rpm php-5.1.6-3.src.rpm apr-util-1.2.7-3.src.rpm pcre-6.6-1.1.src.rpm {code} Then install these SRPMs: {code:none} rpm -Uvh *.src.rpm {code} Then build RPMS: {code:none} cd /usr/src/redhat/SPECS rpmbuild -ba apr.spec {code} Building of httpd and its dependencies should be no problems. But unfortunately the building of php5 is not smooth. Build fails with the following errors: {code:none} checking for C compiler default output file name... configure: error: C compiler cannot create executables See `config.log' for more details. error: Bad exit status from /var/tmp/rpm-tmp.21471 (%build) {code} I have tried many ways to resolve this error but all failed. Finally I found http://bugs.php.net/bug.php?id=36419 via search engines. According to this page, I removed "-Wno-pointer-sign" in php.spec, as a result, this error disappeared! 2007-03-18 01:01:07.0 2007-03-18 00:52:00.0
