- how to set path to c++ headers in Ubuntu
how to set path to c++ headers in Ubuntu 14.04?
So I've done this in the past with 10.04 and 12.04, but I can't seem to figure this out in 14.04. I read on some old forum that it can't be done if using gnome desktop. I hate Unity, so here I am. There has to be a way. I've tried editing the .profile file by adding to the end of the file
I've tried other variations of this, as well, but no luck. I broke Ubuntu with one attempt and had to log in as root from a recovery bootup to fix it. It's fixed now, but I still can't seem to set the path. I'm pulling my hair out here. If anyone can help, I'd appreciate it.

Why a desktop would need such paths? The managed packages should install into well known locations, i.e. be found automatically.
Do you perhaps have a non-managed source install of some library that you want to link against when compiling one of your programs? How do you compile? With a build system? At least a Makefile?
The PATH is a list that a shell uses to locate binaries. Commands.
The compiler has an include-path for headers, but you can add more via its command-line options.
The linker probably needs a path option too to find the non-default libraries.
Neither path uses PATH.

Well, I got it to find one header by putting this in .bashrc
But, if I add another, it won't find the first one.
To answer your questions, I'll use a makefile eventually, but for now, I'm trying a lot of different things with a lot of different little programs that I'd rather not have makefiles for each one, so I just use g++ -o..., and I don't want to have to type the directory each time.
I downloaded the source for openGL and made with cmake, but it didn't put the headers anywhere useful.
edit: libgles2-mesa-dev doesn't seem to have these headers. I got this source from www.opengl-tutorial.org

OK, so they answer my second question on this forum post:

I had not heard of it until your post, but I'm more interested in high performance GPUs than embedded ones, if I understand correctly. Thanks anyway.
