Re: How will I can compile to another architecture from windows 64 bit?

[brainman]

This http://code.google.com/p/go-wiki/wiki/WindowsCrossCompiling is what I do to build windows binaries on linux. Perhaps, you will find it useful.

Thanks Alex!

I read this tutorial, but I don't understand linux command promt. How I can repeat this commands on my win7 machine?

Where I will need set this constant GOOS and GOARCH?

Sorry for my stupid question..

Please, try to translate my instructions and tell us where you get stuck. Will help you.

These are environment variables. You can set them like this:

set GOOS=linux

on windows. You could also put them in a batch file, so you do not need to run them again and again. For example, this

set GOROOT=c:\mygo
set GOPATH=c:\mygopath
set PATH=%PATH%;c:\mingw\bin;%GOROOT%\bin
cd %GOPATH%\src
cmd

is how I start a command prompt with all my Go environment setup. You could have many batch files like that with different environment settings.

I tried on OSX 10.8.3 with go 1.1 beta2 .

It seems that the go compile does not show respect to GOOS and GOARCH.

$ echo $GOOS

windows

$ echo $GOARCH

386

$ go build -o hello.exe hello.go

$ file hello.exe

hello.exe: Mach-O 64-bit executable x86_64

I suspect you didn't "export" your GOOS and GOARCH. Having them defined in your current shell is not enough for new process (go) to see them. I am not sure what the command is on OSX to do that, but on linux I do "export GOOS=xxxx".

aha, yes, it works now .

Thanks.

Try goxc (Cross compiler for Go, written in Go):

Thank you very much for your answers! I understand - it's not my level and I can't to repeat yours recommendations.

Of course, I tried, but I recieved error "go build runtime: windows/386 must be bootstrapped using make.bash" or "gcc" is not an internal or external command, operable program or batch file.

I'd rather wait to be a simpler mechanism compilation like this (I hope this will ever happen):

>go build OS=xxx ARCH=xxx source_dir target_dir

Thank you again and please do not waste your time to me!

To build toolchains for linux x86 and x64:
goxc -t -os=linux -arch="amd64 386"

now to build your code for them:
goxc -os=linux -arch="amd64 386" -d="destination/directory" path/to/app/dir

Is that not what you want?

[Aleksey Levykh]

Yeah!! :) Dobrosław Żybort, Thank You very much!

I tried all possible wrong choices and find one that works for me!

Small instruction for newbies (like me :D [Windows 7 64 bit]) :

1. Download and install needed for you "get tools" https://code.google.com/p/go-wiki/wiki/GoGetTools (hg and git - important, usually)
   
2. Download and install MinGW http://tdm-gcc.tdragon.net/ [This is unofficial builds, but works for me and support 32/64 bits Windows] !Don't forget set PATH variables!
   
3. Go to drive (eg e:) where you planning install Go and type WIN+R>cmd
4. e:\>hg clone -u release https://code.google.com/p/go (version 1.03)
5. e:\>cd go\src
   
6. e:\>all.bat and wait ~1 min
7. Add manually GOBIN, GOROOT, and others Go variables http://golang.org/doc/install/source#environment (you can check current env e:\>go env or simple type e:\>set )
8. Install goxc e:\>go get github.com/laher/goxc https://github.com/laher/goxc
9. Build toolchains for all platforms e:\>goxc -t or needed for you only and cross-compiling works very well (read last message from Dobrosław Żybort)
   
10. That's all :))

Good day, guys!

[Dobrosław Żybort]

Glad I could help.

Oh, and don't forget that cross compilation still don't work with programs/packages using cgo:
