Re: Success! Cross Compiler Linux to Cygwin


Glad the instructions could help :)

I built the cross compiler for 2.95.3, not 3.2, don't know if that will make a difference... but I had the w32api installed, so when I brought over my include and lib directories from my Cygwin install to /cross/i686-pc-cygwin/, I ended up with two directories, /cross/i686-pc-cygwin/include/w32api/ and /cross/i686-pc-cygwin/lib/w32api/

and everything is working alright... Does compiling and linking with -mno-cygwin work under your Cygwin install?

What happens when you try and link an executable using '-mno-cygwin'? Do you
have the full w32api package installed? What (link)errors do you get? Do you
have the the .../i686-pc-{cygwin,mingw} trees set-up?


I have this working but haven't attempted doing it myself yet, a colleague
compiled it on our servers.
