sprintf error when compiling


I had this same issue and then I followed these instructions, however, I am now getting a wierd error after I try to build. (I have installed bison and flex) I am on Mac.

Recent versions of Apple Clang warn about uses of sprintf() in C++, and igraph treats warnings as errors by default. Pass -DIGRAPH_WARNINGS_AS_ERRORS=OFF to CMake. See igraph Reference Manual

I notice that you are using a very outdated version, 0.9.6. Why are you not using the latest 0.10.2, or if you need a software that requires 0.9.x, at least 0.9.10? Many bugs have been fixed since 0.9.6.
