cmd/go: use GOPATH order for compile -I and link -L options Given GOPATH=p1:p2 and source code of just the right form, the go command could previously end up invoking the compiler with -I p2 -I p1 or the linker with -L p2 -L p1, so that compiled packages in p2 incorrectly shadowed packages in p1. If foo were in both p1 and p2 and the compilation of bar were such that the -I and -L options were inverted in this way, then GOPATH=p2 go install foo GOPATH=p1:p2 go install bar would get the p2 copy of foo instead of the (expected) p1 copy of foo. This manifested in real usage in a few different ways, but in all the root cause was that the -I or -L option sequence did not match GOPATH. Make it match GOPATH. Fixes #14176 (second report). Fixes #14192. Related but less common issue #14271 not fixed.

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin
