Why do I get "configure:error: no acceptable C compiler found in $PATH" when installing GCC on my Apache server?

Question

I'm attempting to install GCC 4.5.1 on my Apache server, but it says there is no acceptable C compiler found in $PATH. Any suggestions on what to do would be greatly appreciated.

When I use echo $PATH it prints:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/:/var/lib/:/usr/share/

These are the commands I used to configure GCC:

sudo mkdir /usr/bin/gcc/
cd /usr/bin/gcc/
sudo /gcc-4.5.1/configure

These are the results of those commands:

checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
checking for a BSD-compatible install... /usr/bin/install -c
checking whether ln works... yes
checking whether ln -s works... yes
checking for a sed that does not truncate output... /bin/sed
checking for gawk... no
checking for mawk... mawk
checking for gcc... no
checking for cc... no
checking for cl.exe... no
configure: error: in '/usr/bin/gcc:'`
configure: error: no acceptable C compiler found in $PATH
See 'config.log' for more details.

The file config.log contains:

This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was generated by GNU Autoconf 2.64. Invocation command line was

Solution

Are you trying to build gcc from source ? Then you need a compiler to compile it.. (that's a Catch 22...).

Can't you install a binary package with the compiler already compiled ?
