Basic GOSU Installation dont works

By BinarySoul Date 2014-07-12 23:43

Hello together,

i was trying to install GOSU today, to make my first steps.
Sadly the installation will stop on a certain point without a reason that i can handle.
here´s what i did:

sudo yum groupinstall --assumeyes "Development Tools" #everything works fine!
sudo yum install --assumeyes freeglut-devel freeimage-devel mesa-libGL-devel openal-devel pango-devel SDL_ttf-devel libsndfile-devel libXinerama-devel libvorbis-devel #also fine!
ruby, ruby-devel and gems are already installed @ version 2.0.0p353

then: sudo gem install gosu #brings me to:

Building native extensions. This could take a while...
ERROR: Error installing gosu:
ERROR: Failed to build gem native extension.

/usr/bin/ruby extconf.rb
The Gosu gem requires some libraries to be installed system-wide.

It looks like you are missing the C++ compiler g++. I am not sure how your distribution works, but can you just enter "g++" in a terminal and it will tell you that it is missing, and which package to install?

thats it, many thanks!

for the creator of the homepage here, in Fedora 20, you need to install gcc-c++ seperately with this command:

sudo yum install gcc-c++

thanks for the help

Thanks! I've updated the wiki.
