PECL install fails

Question

Hey!

I have browsed every Google result, read all the forum posts about this error, but I cannot solve it.

When using PECL install for anything, I always end up getting this error:

checking whether the C compiler works... configure: error: cannot run C compiled programs.

Everything else succeeds up to that point them bam!

I'm using CentOS 4.3, PEAR is the latest stable version, GCC is a stable and recent version. Everything is working as it should, but the C compiler always seems to error. I've tried to make tmp have the right privilages for the operation by temporarily enabling it using:

mount -o remount,exec,suid /tmp

But that doesn't work.

I've literally tried everything that has been suggested by to no avail. Any ideas?

Answer 1

Obvious question. Can you run C-compiled programs? Have you compiled a hello-world app (or anything else)?

echo 'int main(){printf("Hello, world!\\n");}'|gcc -x c - -o hello && ./hello

Answer 2

cd ~
mkdir setups
cd setups
wget http://pecl.php.net/get/APC-3.1.2.tgz
tar -xvf APC-3.1.2.tgz
cd APC-3.1.2
phpize && ./configure --with-apxs && make

I quickly wrote that up and was able to install APC with a bit of manual work. Such as copying the module to PHP modules and adding the extension to the php.ini. Works perfectly now.

Answer 3

I'm on Centos 5.3 and I was able to get PECL installers running (APC in my case) successfully by removing the noexec flag on both /tmp and /var/tmp

mount -o remount,exec,suid /tmp
mount -o remount,exec,suid /var/tmp

Doing this only on /tmp didn't work - I still received the error "checking whether the C compiler works... configure: error: cannot run C compiled programs."

Remember to run these remounts again with noexec after your install finishes.

Steven's answer worked for me as well. See http://blog.ntrippy.net/2008/06/installing-peclpear-php-modules-on-rhel.html for more technical details.

Answer 6

I am also trying to install something (pdo_mysql extension) with pecl and the workaround with phpize && ./configure && make is working untill the point I get this error:

checking for mysql_query in -lmysqlclient... no configure: error: mysql_query missing!?

Does anyone know a solution for this? The server is running on CentOS 4 and the mysql version is MySQL 5.1.34

thx

--------edited -----------

Found the solution, I used the wrong mysql installation, I am running a 64 bit server and installed the mysql version of 32 bit :p
