Source Code
The source code is available to download from Sourceforge.net.

Please see the Liquid PCB project page at Sourceforge.net.

Liquid uses Cmake to produce whatever build system you need on Windows or Linux. It has been tested on both platforms and seems to work. If anyone else tries, please let me know how it goes. I'd also be very interested to know if anyone gets it to compile on a Mac. In theory it should work.

Liquid PCB requires wxWidgets, so you will need to download and compile that.
You will also need to download the source for the programming language Lua.
and the source for glpng.

I'm sorry that this isn't easy at the moment. Someone is trying to compile it on Debian, so I should have some Makefiles available in a couple of days. If anyone has tried to compile it on Visual Studio, please let me know if it worked, or if I need to upload more files. Many thanks for your patience.

Windows executable
You can download a Windows executable (Release build): LiquidPCB_2008_02_12.zip.
You'll also need to d-load and install the Microsoft Visual C++ 2005 Redistributable Package which contains the DLLs it needs.

Linux executable
Linux binaries should be coming soon. Someone is trying to compile this for Debian, and I'll make the binaries available as soon as I can.
