Problem with make in vtorcs

[mekimvural]

I was able to install gym-torcs without any problems first time I tried but I had to format my computer and now I get this following error after I enter make command in vtorcs-RL-color. I tried fixes on other issues but they don't seem to be working.

(I attached the entire log)

you have to compile with those flags.
export CFLAGS="-fPIC"
export CPPFLAGS=$CFLAGS
export CXXFLAGS=$CFLAGS
