C compiler gcc not found while installing passenge

Question

I'm trying to install Passenger and Nginx on my VPS.

I followed these instructions and replaced all links of all sources to the current version.

But when i ran the Phusion Passenger installer for Nginx, something with gcc compiler went wrong:

Compiling and installing Nginx...
# sh ./configure --prefix='/opt/nginx' --with-http_ssl_module --with-http_gzip_static_module --with-cc-opt='-Wno-error' --add-module='/usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.17/ext/nginx'
checking for OS
 + Linux 2.6.32-220.el6.x86_64 x86_64
checking for C compiler ... not found

./configure: error: C compiler gcc is not found

What should I do?

OBS: My VPS works with CentOS 6.2 x64

Answer 1

One quick hack (I struggled a lot with it and finally install pre-built) is to install the pre-built package of Nginx rather than compiling it from source.

For RHEL/CentOS create the file named /etc/yum.repos.d/nginx.repo with the following contents:

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/
gpgcheck=0
enabled=1

In above baseurl replace “OS” with “centos” and “OSRELEASE” with “6”.

Finally execute yum install nginx

Reference https://nginx.org/en/linux_packages.html#stable

Answer 2

If you do have gcc installed, the problem stems from /tmp being mounted as noexec. The error doesn't exactly help, but if you remount /tmp as exec you can install passenger properly.

mount -o remount,rw,exec,nosuid /tmp

 sudo

and it worked like charm

Answer 4

Be sure that you sudo, if applicable.

Example:

sudo ./configure ...

Answer 5

Have the same problem and the following commands solve it; (on ubuntu server)

sudo apt-get install linux-kernel-headers
sudo apt-get install build-essential

Answer 6

Got the same error. Just installed gcc and it started working:

yum install gcc
