"No acceptable C compiler found" when installing APC

Question

What do I need to do to get APC to work correctly, it seems I dont have a c compiler in the correct place or something similar to that? Also once it is install how do I verify that it is running correctly?

What operating system is the server? – Beano

Answer 1

Looks like gcc isn't installed. Depending on your release of Linux, the way to install gcc differs. I'm sure if you post which release you're using, we'll be able to help you.

That's just information about the kernel. You need to look know what distribution of Linux you're using. – Ikhnaton

Answer 2

Your system is missing a C compiler (or less likely, it cannot be found).

Likely you just need to do:

sudo apt-get install build-essential

for Debian or Ubuntu or

sudo yum groupinstall "Development Tools"

for Red Hat / CentOS.

By the way, your system's package manager can likely install APC.

On Red Hat Enterprise / CentOS, you may need to enable additional software repositories. EPEL has the package php-pecl-apc for the included (prehistoric) PHP version. – Cornerwise

i installed development toolsthen tried to run pecl install apc and it gave me /var/tmp/APC/apc.c:454: error: 'apc_regex' has no member named 'preg' how do i know if its running? for the php-pecl-apc is it just sudo yum php-pecl-apc? – Fischer

Is PRCE support compiled into your PHP? – Kezer

Answer 3

I solved this via the following:

#rpm -qa | grep gcc

# yum install gcc glibc glibc-common gd gd-devel -y

Answer 4

On our CentOS 6 box I used yum install php-pecl-apc - I'd done some other yum installs first such as glib, gcc. But at least you know yum will handle the dependencies properly. Not actually seen a particular speed increase with it, but I assume this is where tuning comes in.
