Compile error about retro-learning-environment

[nadavbh12]

Are you compiling using the cmake command or via pip install?

[tohnperfect]

I was following the instruction in the README.md,

$ mkdir build && cd build
$ cmake -DUSE_SDL=ON -DBUILD_EXAMPLES=ON ..
$ make -j 4

which is cmake.

[nadavbh12]

Please try checking out v1.0.2 and let me know if that works out.

[tohnperfect]

v1.0.2 of?

[nadavbh12]

Of RLE. As in git checkout v1.0.2

[tohnperfect]

With v1.0.2, I got stucked at the same point as follows,

I checked again I failed to install libsdl-image1.2-dev which I thought I already solved the problem of installing this dependecy. BTW my machine run Ubuntu14.04.
