So I ported the C API for MathGL to D, and it is up at code.dlang.org (under dmathgl). MathGL is a nice plotting library.

http://mathgl.sourceforge.net/doc_en/Pictures.html#Pictures

Later I will work on porting the C++ interface, but so far it at least works for the simplest sample. (Not tried anything else as they are all written in C++).

DMD gave me an error message for the following declarations:

double mgl_rnd (...);
double mgl_rnd_ (...);

It says I need at least one fixed argument first. But the C headers are as they are.

I could work around this by writing a C stub

double mgl_rnd_(int dummy, ...)

but is there any way to call these functions without this workaround?
