GCC not runnable on FreeBSD

Question

I'm trying to run GCC on FreeBSD and I get this error:

% gcc
ar: unrecognized option `--plugin'
usage:  ar -d [-Tjsvz] archive file ...
        ar -m [-Tjsvz] archive file ...
        ar -m [-Tabijsvz] position archive file ...
        ar -p [-Tv] archive [file ...]
        ar -q [-TcDjsvz] archive file ...
        ar -r [-TcDjsuvz] archive file ...
        ar -r [-TabcDijsuvz] position archive file ...
        ar -s [-jz] archive
        ar -t [-Tv] archive [file ...]
        ar -x [-CTouv] archive [file ...]
        ar -V

I have installed the following version of GCC using the binary pkg:

% pkg info gcc
gcc-4.7.3_1
Name           : gcc
Version        : 4.7.3_1

Options        :
        BOOTSTRAP      : off
        JAVA           : on

I have installed the port version as well with the same results.

What can possibly be wrong?

Since FreeBSD 10 Clang is the new default compiler.

You could try to compiler your code with Clang or you need to install a GCC version like you did.

But before the switch to Clang, FreeBSD used version 4.2 of GCC and the binary of this GCC was /usr/bin/gcc, so the newer ports of GCC needed to name there binary differently.

Because of that, all GCC ports have a binary called /usr/local/bin/gccXY, where XY is the version number.

When you install gcc4.7 on FreeBSD you don't get a /usr/local/bin/gcc thanks to the old behaviour, instead you get /usr/local/bin/gcc47`.

Long story short, when you want to compile your code with GCC 4.7 you need to use gcc47 and not gcc.

But maybe you should give Clang a try, since it is always a good idea to compile your code with different compilers to see if your code depends on a compiler. Because if it doesn't compile your code is probably broken or you found a compiler bug which is awesome.

Also take a look at Why is FreeBSD deprecating GCC in favor of Clang/LLVM?

So, /usr/local/bin/gcc is still 4.2? Anyhow with some fiddling I successfully used /usr/local/bin/gcc47 to build! Thanks! — ase, Jun 28 '14 at 11:24
@adamse No since FreeBSD 10 there is no gcc anymore only clang — Raphael Ahrens, Jun 29 '14 at 00:38
