Re: [Iverilog-devel] MS Windows devel environment suckage (was Re: Banishing lxt2 output to a thread)

[Richard M. M. <rm...@ai...>]

When I have to make Windows binaries that do not depend on Cygwin1.dll,
I use the -mno-cygwin switch in Cygwin.  You have to have the Cygwin
Mingw package installed, but it's pretty painless as compared to using
the MingW compiler.

I've also built Windows executables and shared libraries in the past
under Linux with a mingw gcc cross compiler.  It worked really well.  At
one time, there was a complete package (based on gcc 2.95) somewhere on
the net, so you didn't have to build it yourself.  Interestingly, gcc
2.95 generated code that was a full 2X faster and 2X smaller than the
gcc 3.X compiler.  I hope the current gcc 4.X compilers have closed the
gap.
