Building Go on Cygwin

[bruno oliveira (zack)]

Hello all!

I've been trying to compile Go for my windows laptop for a few hours,
but no success. I was wondering if anyone has seen something similiar

Here's my set up:

> Windows 7 x64
> Cygwin with gcc-4.5.3, make 3-82, bison, binutils and the mingw64-x86_64 toolchain

GOROOT = /cygdrive/d/go
GOBIN = $GOROOT/bin
GOARCH = amd64
GOOS = windows

./all.bash runs with no problems at all up until this point: (building
lib9). I've been googling for a solution, but still no luck. Has
anyone seen this before ? Or have any idea of how to fix it?

Thank you a lot in advance.

The newest weekly release contains "all.bat" which makes it is very
easy to compile Go on Windows because it only depends on "gcc".

Make sure "gcc" in "Path", set GOROOT, GOBIN, GOARCH and GOOS, invoke
"all.bat" and everything should be done in few minutes.

These environment variables don't need to be set now. The dist tool is smart enough
to detect them. Just cd to src and then all.bat will do.

Thank you for helping guys!

Just to make sure we're all on the same page...

I was trying to compile the build you get with "hg clone -u release
https://go.googlecode.com/hg/ go"
as if I were in linux (taking that I'm on cygwin... But I couldn't
find all.bat in there

So as for the weekly release, I'm getting this one: "gowinamd64_weekly.
2012-02-14.zip"
from "http://code.google.com/p/gomingw/downloads/list"

But with that I've got 2 issues, one of them I managed to solve:

Issue #1.

Whenever I tried to run all.bat from Windows CMD (or even when in bash/
cygwin) I was getting "Access Denied".
Actually... just by running "gcc" was getting me that. I would work if
I triggered it with "gcc-4",
so I'm guessing Windows won't follow the symlinks // the gcc file)

So within <CYGWIN_ROOT>\bin I renamed "gcc.exe" to "gcc.exe.bkp" and
created a batch file "gcc.bat"

REM gcc.bat
REM ======= Triggers gcc-4 properly ===========
D:\cygwin\bin\gcc-4.exe %*

Now I'm able to run GCC from Windows CMD/Prompt or Cygwin, however,
somehow I'm still being unlucky...

This is the STDOUT from the all.bat (run from Windows CMD, I've tried
the same thing using bash/cygwin,
but the output is almost the same). It fails at two points.

Could you please take a look? Thank you.

You need a native GCC, like mingw, not cygwin.

Just one question:

When I got my cygwin (with setup.exe),
I also issued the install of the mingw toolchain (mingw64-x86_64)
along with make, gcc-4, bison, awk and binutils. That won't do?

Should I get the mingw from the official http://www.mingw.org/ site ?

Thank you very much!

Cygwin is a sign of impeding pestilence. I avoid it at all cost. If
there's nothing forcing you to use it, I recommend deleting it from
your hard drive, until it's too late.

Maybe the mingw from cygwin works, maybe not.

That would be my recommendation, yes.

Sorry for the silly question, but what are the pre-requisities to
build it on windows?

The README file won't mention it and the doc/install.html still thave
that Windows as a TO-DO...

I just did as said: Dropped my cygwin and got the "official" mingw
toolchain. I can properly run GCC and Make from my windows prompt
without any error messages. All variables are set all right, but
still:

D:\>cd go\src

D:\go\src>all.bat

# Building C bootstrap tool.
cmd/dist

// Here it ends, no warnings, no error messages... nothing at all. I'm
kinda lost now...

mingw and hg native for windows.

http://www.mingw.org/wiki/InstallationHOWTOforMinGW

http://mercurial.selenic.com/wiki/Download#Windows

then add C:\MinGW\bin to your PATH.

after that use only cmd.exe and use all.bat or make.bat
