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

[Mathias Wein]

Hi,

const char *ext = strrchr(filename, '.');
should indeed be correct, if load_jpeg produces errors it has nothing to do
with the ext pointer...if you tell me the error, i could probably help you.
Right now i don't see anything obvious there...

casting away a const is rarely a good idea...and you can cast '.' to int and
back just fine...
