====== LSWS PHP/LSAPI Build troubleshooting guide (Archive Only) ======
===== Preamble =====
The following is a list of common error messages encountered during the php build stage for LiteSpeed Web Server (LSWS) and their relevant fixes. The general PHP/LSAPI build procedures are described in [[http://www.litespeedtech.com/support/wiki/doku.php?id=litespeed_wiki:php:lsapi|PHP with LSAPI Compile/Install How-To]]. As of this writing, the latest PHP version is 5.2.16. The latest LSAPI released is version 5.5. We will use php 5.2.16 and LSAPI 5.5 as an example to build LSPHP.
In most cases, control panel users do not need to build PHP manually anymore, most of the time control panels have pre-built RPM/APT packages. For users not using a control panel, you may use the LiteSpeed repositories for CentOS/Debian/Ubuntu systems.
This list consists of archived documents which may contain out of date information but may also provide a good starting place in solving any errors you encounter while compiling PHP. PHP compilation is a general topic and is not limited to LSWS. If you do not find an answer here, you are free to "google" your error message for solutions. Again, we recommend you to go through RPM/APT packages installation process instead of PHP compiling unless you have a "have to" reason to compile manually.
===== Procedures =====
1. Pre-requisites
Make sure all the build tools are installed and ready:
patch, gcc, glibc, libstdc++, gcc-c++, binutils, libtool, autoconf, make
CentOS: yum install patch gcc glibc libstdc++ gcc-c++ binutils libtool autoconf make
CentOS (64bit): yum install patch.x86_64 gcc.x86_64 glibc.x86_64 libstdc++.x86_64 gcc-c++.x86_64 \
binutils.x86_64 libtool.x86_64 autoconf.x86_64 make.x86_64
Ubuntu (32bit or 64bit): apt-get install patch gcc glibc libstdc++ gcc-c++ binutils libtool autoconf make
2. Download PHP source and unpack it
# wget -N http://us2.php.net/get/php-5.2.16.tar.gz/from/us.php.net/mirror
# tar -zxf php-5.2.16.tar.gz
3. Download LSAPI source and unpack it
# cd php-5.2.16/sapi
# wget -N http://www.litespeedtech.com/packages/lsapi/php-litespeed-5.5.tgz
# tar -zxf php-litespeed-5.5.tgz
**Note:** LSAPI 5.5 is shipped with PHP source from PHP 5.3 onward. This step can be skipped if you build PHP 5.3 or above.
4. cd to php source directory and rebuild configure script
# cd ..
# touch ac*
# ./buildconf --force
===== Possible errors and their fixes =====
**Note:** OpenSUSE error fixes are generally the same as the CentOS fixes listed below except that "yum" should be replaced with "zypper".
**Error Message:**
Forcing buildconf
./buildconf: line 41: make: command not found
**Reason:** Missing 'make' program in the build system.
**Fix:** Install 'make' program.
CentOS: yum install make
CentOS (64bit): yum install make.x86_64
Ubuntu (32bit or 64bit): apt-get install make
----
**Error Message:**
buildconf: autoconf not found.
You need autoconf version 2.13 or newer installed
to build PHP from CVS.
make: *** [buildmk.stamp] Error 1
or
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.
**Cause:** Missing 'autoconf' program in the build system.
**Fix:** Install 'autoconf' program.
CentOS: yum install autoconf(.x86_64)
Ubuntu (32bit or 64bit): apt-get install autoconf
----
**Error Message:**
Forcing buildconf
buildconf: checking installation...
buildconf: autoconf version 2.59 (ok)
buildconf: Your version of autoconf likely contains buggy cache code.
Running vcsclean for you.
To avoid this, install autoconf-2.13.
Can't figure out your VCS, not cleaning.
**Cause:** 'autoconf' program is buggy in the build system.
**Fix:** Install 'autoconf213' program.
CentOS: yum install autoconf213(.x86_64)
Ubuntu (32bit or 64bit): apt-get install autoconf2.13
export PHP_AUTOCONF=/usr/bin/autoconf-2.13
export PHP_AUTOHEADER=/usr/bin/autoheader-2.13
===== Configure/Compilation =====
4. Configure/Compile PHP with LSAPI (LSPHP)

'--enable-sysvshm=shared' '--enable-sysvsem=shared' '--enable-posix=shared' '--with-unixODBC=shared,/usr'
**Note:**
* for 64bit system, '--with-libdir=lib64' should be used in configure option
* it saves quite a bit of time to get all needed packages installed in one shot instead of going through each error and fix them. For the example compile options above, just issue the following command to get all the needed packages installed.
