Re: [libredwg] Compiling error

[Jonathan Greig]

Gagan,
malloc's return type needs to be type casted. See here for more info: http://stackoverflow.com/questions/5099669/invalid-conversion-from-void-to-char-when-using-malloc

Stack overflow is the best resource for programmers :D

I think you mentioned you were familiar with Python so this is similar to a TypeError.

You might as well put the typecast in there for good measure so it plays nice with g++. I bet if you compile with gcc instead, it doesn't complain about it.
