+# Go plugin for MXE
+
+See also article [cross-compile go code, including cgo][1]
+by Dimitri John Ledkov.
+
+[1]: http://blog.surgut.co.uk/2014/06/cross-compile-go-code-including-cgo.html
+
+Package `go-native` installs native Go 1.4. This version of Go
+doesn't depend on Go installation.
+
+Package `go` uses native Go 1.4 as a bootstrap and installs Go 1.6
+as a cross-compiler to windows/386 or windows/amd64. Versions of
+Go starting with 1.5 need Go installation to build.
+
+To build Go packages for windows/386 or windows/amd64, you have to set
+the [GOPATH](https://golang.org/doc/code.html#GOPATH) environment variable
+and call `usr/bin/$(TARGET)-go` wrapper script.
+
+## Example
+
+Building [gohs](https://github.com/flier/gohs), GoLang Binding of
+[HyperScan](https://01.org/hyperscan).
+
+```
+$ make hyperscan go MXE_PLUGIN_DIRS=plugins/go
+$ mkdir gopath
+$ GOPATH=`pwd`/gopath ./usr/bin/i686-w64-mingw32.static-go get \
+ github.com/flier/gohs/examples/simplegrep
+$ ./gopath/bin/windows_386/simplegrep.exe root /etc/passwd
+Scanning 42 bytes with Hyperscan

+Subject: [PATCH] cgo: add environmental variable override for pkg-config
+
+Allow overriding default name of `pkg-config` utility via
+environmental variable PKG_CONFIG (same as used by autoconf
+pkg.m4 macros). This facilitates easy cross-compilation of cgo
+code.
+
+Original patch against Go <= 1.4 was written by
+xnox_canonical <dimitri.ledkov@canonical.com> in 2014.
+Source: https://codereview.appspot.com/104960043/
+
+Rebased against Go 1.6.2 by Boris Nagaev <bnagaev@gmail.com>.
