cannot compile code

[AdrienLemaire]

Hi, I tried to run your code, without success. I'm on arch linux, using g++ 4.9.2. Any idea what is wrong below?

I havn't seen this until now, mainly because I'm watching other projects which has many pull requests. I know it's too late, just in case you're still interested in this issue. Try to change line 326

char* pos;

to

const char* pos;
