Cannot run C++ program when using sublime-build, works fine when running from terminal - c++

Question

I'm trying to run a C++ program on Linux/Ubuntu 14.04
I'm using the SFML library, the tutorial suggests to include this line before running if SFML was installed in a non-standard path (which it was):
$ export LD_LIBRARY_PATH=<sfml-install-path>/lib
I can run the program from the terminal using the following input:
$ export LD_LIBRARY_PATH=/home/dan/SFML-2.3.1/lib && ./YorickTheSavant
However, when attempting to launch the program in Sublime Text 2 with a sublime-build file, I get the following error:
[Errno 2] No such file or directory
[cmd: [u'export', u'LD_LIBRARY_PATH=/home/dan/SFML-2.3.1/lib', u'&&', u'./YorickTheSavant']]
[dir: /home/dan/yorickthesavant]
[path: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/dan/.rvm/bin]
[Finished]
Here is my sublime-build file for reference:
{
"cmd": ["g++", "-m32", "-c", "-std=c++11",
"src/buff.cpp",
"src/card.cpp",

},
{
"name": "Run",
"cmd": ["export", "LD_LIBRARY_PATH=/home/dan/SFML-2.3.1/lib", "&&", "./YorickTheSavant"]
}
]
}
The "Run" variant is the one I'm using. How would I make it so that this line is automatically included when the game is launched outside of the terminal and in Sublime Text 2?

Answer 1

The cmd key in .sublime-build files specifies the program to run.
The first value is expected to be the program and the rest are the arguments,
so it fails when it cannot find a program called export - because it is a shell built-in.
To run the entire command in a shell (like you would when doing it manually), you can specify "shell" : true in your Run variant (or use shell_cmd instead of cmd):
{
"name": "Run",
"cmd": ["export", "LD_LIBRARY_PATH=/home/dan/SFML-2.3.1/lib", "&&", "./YorickTheSavant"],
"shell" : true
}
This should work better than invoking /bin/sh -c <stuff> directly, and I don't think you'll need to condense the entries in the cmd array into a single string anymore.
Alternatively, you could also try using the env key (also found here) to specify the LD_LIBRARY_PATH environment variable before running your executable:
{
"name": "Run",
"cmd": ["./YorickTheSavant"],
"env" : { "LD_LIBRARY_PATH" : "/home/dan/SFML-2.3.1/lib" }
}
