Default php and oci8 issues

Title: php and oci8 issues


* I am compiling php 5.2.5 with OCI8 on centOS 5. I have installed the following from oracle




These were the compile used while configure php

'./configure' '--prefix=/usr/local/php-5.2.5' '--cache-file=../config.cache' '--with-libdir=lib' '--with-config-file-path=/usr/local/php-5.2.5/etc' '--with-config-file-scan-dir=/usr/local/php-5.2.5/etc/php.d' '--disable-debug' '--with-pic' '--disable-rpath' '--with-pear' '--with-bz2' '--with-curl' '--with-exec-dir=/usr/bin' '--with-freetype-dir=/usr' '--with-png-dir=/usr' '--enable-gd-native-ttf' '--with-gettext' '--with-gmp' '--with-iconv' '--with-jpeg-dir=/usr' '--with-openssl' '--with-pspell' '--with-pcre-regex' '--with-zlib' '--with-layout=GNU' '--enable-exif' '--enable-ftp' '--enable-magic-quotes' '--enable-sockets' '--enable-sysvsem' '--enable-sysvshm' '--enable-sysvmsg' '--enable-wddx' '--with-kerberos' '--enable-ucd-snmp-hack' '--with-snmp=shared,/usr' '--with-unixODBC=shared,/usr' '--enable-shmop' '--enable-calendar' '--with-mime-magic=/etc/httpd/conf/magic' '--without-sqlite' '--with-libxml-dir=/usr' '--enable-dom=shared' '--with-pgsql=shared' *'--disable-dba' '--disable-xmlreader' '--disable-xmlwriter' '--without-gdbm' '--with-gd=shared' '--with-imap=shared' '--with-imap-ssl' '--with-mysql=shared,/usr' '--with-mysqli=shared,/usr/bin/mysql_config' '--enable-mbstring=shared' '--enable-mbregex' *'--with-libmbfl' '--with-pdo-mysql=shared,/usr/bin/mysql_config' '--enable-pdo=shared' *'--with-pdo-odbc=shared,unixODBC,/usr' *'--with-xmlrpc=shared' '--with-ncurses=shared' '--with-ldap=shared' *'--with-pdo-pgsql=shared,/usr' '--without-pdo-sqlite' '--with-db4=/usr' '--enable-force-cgi-redirect' '--enable-pcntl' '--with-xsl=shared,/usr' '--enable-xmlreader=shared' '--enable-xmlwriter=shared' '--enable-fastcgi' *'--enable-cgi' '--with-apxs2=/usr/sbin/apxs' '--with-oci8=shared,instantclient,/usr/lib/oracle/' '--enable-sigchild'

Compile and install was successful. Apache was not working and these are the sealert messages, i am putting here only summary, raw audit message and suggestions, which i followed in the same order below to make Apache work

1. Summary

* * SELinux is preventing /usr/local/php-5.2.5/bin/php from loading

* * /usr/lib/oracle/ which requires text

* * relocation.

* * *setsebool -P allow_execheap=1

Has anybody compiled PHP 5 with Oracle client on Redhat or Centos 5 with out any selinux issues? Is this the known issue or my procedures are wrong. I have tried compiling couple of weeks back with Red Hat ent5 php source rpms and got the same selinux errors. Any possible help to put back allow_execheap=0 *httpd_disable_trans=0.
