RE: [Yafray-devel] Compiling yafray, error in basictex.cc

[Deuss Mario]

I know Maxwell, used its testversion some time ago. But as I studying computer 
science and we implemented a simple raytracer in c++, I'm more interested in a 
opensource project. For sure my problem is not really a serious one, but I have 
to start somewhere.
I was also wondering about platform compatibility, and thought this problem 
could interest someone, as read of the goal to make
yafray compile without any interaction of the user. Hope I didnt bother you,

Try casting filename to char*. Like this:

char *ext = strrchr( (char*) filename, '.');
