Can't build on windows. #62

Closed lukasmalkmus closed 7 years ago

lukasmalkmus commented 8 years ago

OS: Windows 10 Prof. 64 Go Version: 1.6

I tried to build a small sample program. It is designed for my Raspberry Pi. However, I failed very early when building was not possible. I face these errors when running go build:

vendor\github.com\kidoman\embd\host\generic\i2cbus.go:72: undefined: syscall.SYS_IOCTL
vendor\github.com\kidoman\embd\host\generic\i2cbus.go:72: not enough arguments in call to syscall.Syscall

They only appear if I import the Raspberry Pi Drivers. Building without the rpi package is possible, but won't work obvisiously.

Same Issue

Set the appropriate environment variables before building.

Example: export GOOS=linux and export GOARCH=arm

Then do a go install ./... and look under your go/bin directory. Remember that you're looking for a binary for another platform now -- it won't have an .exe extension. SCP the binary you find to your Raspberry Pi and you should be good to go.

Oh wow, this issue is old. This was in my early go days where I wasn't familiar with the go tooling. Reading my own issue a year later makes me feel a little bit embarrassed. Anyway, thanks for the reply. Might be useful many new go newbies :)

No worries. I remember being blown away by setting some environment variables and compiling for a different platform too. :smile:

wedgen commented 7 years ago

What about cross platform compiling? The OS its going on is Linux and the Arch is arm but wanted to build on windows. Is that possible?

danesparza commented 7 years ago

Absolutely. That's exactly what I do. I prefer to use the git 'bash' commandline window, but the concept is the same on windows: Set your GOOS and GOARCH environment variables and then run go install ./...
