multiple definition of `_imp__sqrt'

[josephspurrier]

I'm trying to test each of the example programs.

I am using the x86 Go compiler with x86 GCC compiler. I added the cd folder inside of the lib folder with the correct files from this URL:
https://sourceforge.net/projects/canvasdraw/files/5.9/Windows%20Libraries/Static/

When I try to test cbox.go, these are the errors I get when I try to compile:

same under x64...

[matwachich]

This is a conflict between ntdll and msvcrt libs. I have no idea how to solve it.

[kvarekamp]

same for me using tdm gcc 64. Also happens when I try to use iupmatrixex. I have no idea how to solve it either.
