Fix minor gcc compile errors #12

Closed olsoneric closed 9 years ago

olsoneric commented 9 years ago

Fix minor issues to get it to compile with gcc 4.8.2:

extra qualification [-fpermissive]
ignoring return value of char* fgets [-Wunused-result]
printf with std::string

Looks good to me, thanks for contributing! Sorry this took a while to get to - I reviewed it, then didn't come back because I thought I merged it already.

A shame there's no better way to skip 3 lines with those C file APIs, but hey, do what you gotta do, and clean compiles are important.

No problem. Using OSVR will likely save me a lot of code in the long run.
