I have been fighting to get FCEUX installed on my iMac ever since I got it.  It came with Mountain Lion and I was able to install FCEUX on Lion without issue, but Mountain Lion was a completely different story.  I initially tried installing XQuartz (make sure to do this first if you have not already) and then FCEUX using homebrew as I had done before.

brew update
brew doctor
brew install fceux

But got the following error:

==> Downloading
Already downloaded: /Library/Caches/Homebrew/fceux-2.1.5.tar.bz2
==> Patching
patching file src/drivers/sdl/SConscript
==> scons
env.ParseConfig(‘pkg-config –cflags –libs gtk+-2.0’)
File “/usr/local/Cellar/scons/2.2.0/libexec/scons-local/SCons/”, line 1554:
return function(self, self.backtick(command))
File “/usr/local/Cellar/scons/2.2.0/libexec/scons-local/SCons/”, line 596:
raise OSError(“‘%s’ exited %d” % (command, status))

After doing some research, I discovered that it was having issues finding the required X11 packages and was failing. I tried specifying

PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig/ brew install fceux

But that also did not resolve the problem. I found someone else having the same issue as me on github and commented that I was having the same issue, but didn’t get back anything that worked, so I decided to go straight to source and see if I could compile and install it from the FCEUX site.

I downloaded the latest version 2.2.0 src tarball and read the “”. The readme stated that it should be compiled and installed using scons, so I ran the scons command within the directory and got the same error again. So I decided to break into the SConscript file and see if I could figure out how to fix the error. I found the line that was running pkg-config on gtk+-2.0 from the error and added


to the front of the pkg-config command to see if that would work and to my surprise I got passed the error. The next error I received was that liblua could not be found. That was easy to fix by running

brew install lua

After that I ran scons again and to an even greater surprise it compiled without error. After that I was able to run scons install to install the binary and then ran fceux and it ran without error.

    Hi Nate.
    Im triying to compile FCEUX in Mountain Lion aswell, and have the same errors as you, with Brew and Scons aswell.

    You think it will work if you could send me a complied version on Fceux ? i would be eternally grateful. Im not a developer, so im kind of lost,

    I’m actually on Mavericks now, but I will see if I can find the source that I used to build the version I’m currently using and send to you.

    Out of curiosity, are you installing fceux via homebrew? I submitted my changes back to the fceux developers and I thought they integrated them into the latest version.

    If anyone is interested, I’ve also fixed this on Yosemite. See my bug and resolution post on FCEUX’s site.

    I’m also looking for a compiled version that will run on El Capitan. I like to hack roms once in a while and would love it if I could just do so on my laptop without having to install windows on another partition.
