Unfortunately for most of my working day I am stuck with a windows laptop ( Win 8.1). Before trying a ubuntu VM kind of solution on windows I wanted to see if I could get cockroach compiling on either cygwin or mingw32.
On Cygwin ,there is no stable version of GO( only experimental) , So I tried using the windows version of Go and cygwin shell + other tools on cygwin ( e.g gcc, make , git etc) but with no luck . I run into weird errors - Example git complains sync.go has changed in glock and asks me to stash changes before proceeding. But when I do a git diff nothing has changed. I have no clue what is going on.
And Ming32-make can't handle spaces in the names and Git, Hg ,Go etc are all installed in Program Files. I could keep all dependencies in paths with no spaces , but that is too much work since my other projects also need these tools and it is a little difficult to work around every issue the arises because of space in paths.
Any pointers would be appreciated. If not I'll just go the VM route
Thanks

Hey Guru,
I've tried a number of times and came fairly close to getting the dev environment working in both cygwin or some of the different environment installers for mingw out there. But the last time I tried was about 4 months ago.
An ubuntu VM would work, but it's not a good solution.
I'll give it a another shot and see if I can sort out what's wrong. But sadly right now it's not a priority right now, so it might take a bit of time.
Cheers,
Bram

Thanks Bram. I'll keep ploughing through it too and will update this thread if I can get it working

I got "go get" to download all dependencies on cygwin and when I try to do a make build , I get a couple of category of errors
1) gcc warnings in various dependencies which get treated as errors ( I assume I can use some flag on gcc to ignore these warnings? )
2) Errors like "skipping incompatible /usr/lib/gcc/x86_64-pc-cygwin/4.9.2//libgcc_s.dll.a when searching for -lgcc_s" . I have bolded them in the below logs
Any pointers? I'll continue to try and find what the issues are and fix them.
PS: I am using Windows Go (not compiled for Cygwin) for running the build from within Cygwin.
My GCC version is
$ gcc -v
Using built-in specs.

Two observations:
* I've never heard of go running in cygwin correctly. I wouldn't even bother that route.
* the specific error "skipping incompatible /usr/lib/gcc/x86_64-pc-cygwin/4.9.2//libgcc_s.dll.a when searching for -lgcc_s" has to do with how you installed gcc. Do you have a windows box? I'd suggest using mingw, perhaps from msys2.

Thanks.yes I do have a windows box. I'll proceed with the mingw route.
Anyway meanwhile I got a free tier AWS EC2 instance going and the build works like a charm on linux.

In our build system we wrap C libraries in a CGO-based build (so we're compatible with `go get`) instead of using their own configure/make scripts (these are the cockroachdb/c-* repos). In each repo there is a cgo_flags.go file which defines the flags that a configure script would use:
To build on windows we'll need to add some `#cgo windows` lines to define the flags that we need there.

Thanks Ben. I set up msys2 instead of cygwin and git for windows (instead of regular git from the original source because it does not support symlinks) and got go to clone and get all dependencies fine.
Now I am stuck at cgo part of the build where go is not able to find C / C++ functions , pasting the error message here in case I am doing something obviously wrong.
New to golang , so will play around some more with cgo to see if I can figure it out
The cgo flags for example for c-snappy seem platform independent, so do we still need any 'windows' specific stuff in there for it to work?
// Package snappy uses the cgo compilation facilities to build the
// Snappy C++ library.
package snappy
// #cgo CXXFLAGS: -std=c++11
// #cgo CPPFLAGS: -DHAVE_CONFIG_H -Iinternal
import "C"
But when I try to do a go build on just c-snappy I get ( error in red below)

It looks like it's not even trying to compile snappy-c.cc where snappy_compress and snappy_uncompress are defined. Those files are symlinks; do symlinks work properly on windows with this toolchain?

Looks like I have hit a dead end, Rocks DB does not compile on MSYS2(MINGW64_NT) , but does compile on Cygwin. Whereas there is no Golang ( at least stable) for Cywgin.

Thanks. But that is for compiling rocks-db on cygwin ( which is an almost POSIX compliant env using cygwin.dll), so it has stuff like sys/mman.h ( for memory mapping etc). Rocks DB is dependent on such APIs. I am using MINGW/MYSYS environment which provides no POSIX compliance and uses Windows native APIs , so rocks-db build breaks.
Golang for windows is built on MINGW and I did not find any stable golang for Cygwin.
So I guess I'll stop my efforts on this for now , unless somebody knows a way around.
Instead I'll try to build a basic Java client for cockroach.
