Scenario / Questions

When I try to install APC via pecl install APC-3.1.5
or even pecl install APC I get following error when the package comes to the make command:

ERROR: `make' failed

I installed all possible missing things:

yum install php-devel httpd-devel
yum groupinstall ‘Development Tools’
yum groupinstall ‘Development Libraries’

And still nothing.

Find below all possible solutions or suggestions for the above questions..

Suggestion: 1

Try

yum install pcre-devel

before installing APC.

On Debian use

aptitude install libpcre3-dev

instead.

Suggestion: 2

I would compile from source. Make sure you delete anything that the package installers left behind. You probably have old extension directories laying around from older php versions. rm -rf them and their contents so you wont have any confusion.

cd ~ 
mkdir setups
cd setups 
wget http://pecl.php.net/get/APC-3.1.9.tgz 
tar -xvf APC-3.1.9.tgz 
cd APC-3.1.9
phpize
./configure --enable-apc --enable-apc-mmap --with-apxs --with-php-config=/usr/local/bin/php-config
make

For the config= argument, run which php, and add -config to the result

If you get this error (Same as one you posted)

Then you have to install pcre and make sure it’s from the / directory or it will not install.

yum install pcre-devel

make
make install

Suggestion: 3

it looks like you are trying to install APC on a system running PHP < 5.2.x. Version 3.1 of APC requires 5.2.x. I’m assuming your running CentOS 5.5 which ships with PHP 5.1.x.

try compiling and installing APC 3.0.19 from http://pecl.php.net/package/APC. We have had success deploying APC 3.0 on our CentOS servers.

In Ubuntu:

aptitude install libpcre3-dev

And then:

pecl install apc
