Installer for Windows, was: Maxima 5.30.0 / wxMaxima 13.04.1 Windows Binaries

Hey,

I did a little research today and I am not satisfied with the results: GCL 2.68 is RC and has no windows binaries. It does not compile with GCC newer than 3.1. I have some old build environments, but nothing that old. Furthermore I am not happy with the idea of using an 10 year old compiler to compile an 8 year old RC-compiler to compile something with it, if you catch my drift. So - can u suggest an alternative to GCL for Windows? I used GCL at all because Maxima 2.8 was build with it, and Version 2.6.6 because it is the latest stable release.

Furthermore, can somebody confirm that the problems caused by the current build (Problems 38, 47 of rtest1) are indeed errors? Or is there just a problem in the test regarding sime simplification?

Cheers,

Nico

Sorry about this.  load draw does not work, but the draw, draw2d, draw3d
continue to work anyway.  I guess it is no longer necessary to load draw
before using it's functions.  My mistake.
Sorry,
Rich

I tried the new installer.  Thanks, us Windows addicts have not had a new
version in a while.  I have not tested it out that much yet but I did notice
that load(draw) does not work.  Consequently I can't get draw, draw2d,
draw3d, etc to work.

Here is the error.

These are known issues with gcl.  While the error is small, it should
be zero.  I think the issue is that gcl is not correctly rounding.
