I also needed to make sure I had several different gcc packages installed on my Ubuntu machine to support this process. I installed them with:
sudoaptgetinstallgccmultilib
The trickiest part though was building the various bits. I used make.bash. Perhaps there is a way to do this with all.bash. But I wasn’t sure what that actually did and whether it would pick up the particular environment variables I wanted to specify. So I ran make.bash multiple times. I start by building the Windows stuff (I’ll explain why in a sec):
cdsrc
This enabled CGO and specifies special C and C++ compilers to use in order to build the native exes. This is for the win32 platform. Then,I run the command again for win64 but add the –no-clean option:
$ GOOS=windows GOARCH=amd64 CGO_ENABLED=1 CXX_FOR_TARGET=x86_64-w64-mingw32-g++ CC_FOR_TARGET=x86_64-w64-mingw32-gcc ./make.bash –no-clean
Finally,I do a build for native Linux (again with –no-clean)
$ GOOS=linux GOARCH=amd64 CGO_ENABLED=1 CXX_FOR_TARGET=g++ CC_FOR_TARGET=gcc ./make.bash –no-clean
Now you might wonder why I built them in this order. I played around with this quite a bit actually. The issue is that these builds are somehow “stateful”. The last build seems to set some defaults somewhere or something. You’d think that it would be sufficient to just specify GOOS and GOARCH whenever you ran the go tool,but it isn’t. If I build Linux first and Windows last,the Linux version wouldn’t work (because the last build was Windows and that messed up Linux). And yes,building Linux last messes up the Windows builds. BUT,that can be overcome by setting some environment variables.
The way I dealt with this was to create some special scripts:
$ echo ‘export GOOS=windows; export GOARCH=386; export CGO_ENABLED=1; export CXX=i686-w64-mingw32-g++; export CC=i686-w64-mingw32-gcc’ > go-win32
$ echo ‘export GOOS=windows; export GOARCH=amd64; export CGO_ENABLED=1; export CXX=x86_64-w64-mingw32-g++; export CC=x86_64-w64-mingw32-gcc’ > go-win64
Notice the fact that I explicitly set the values of CXX and CC. What I normally do is just source these,i.e.,(NOTE THE ‘.’)
$ . go-win32
This sets the environment variables needed to perform a win32 build. After that,I can just use the go tool as usual,e.g.
