Can't build my program using gccgo on Mac OS X 10.9 Mavericks

[michal]

Hi guys,

I installed gcc 4.9 with gccgo using brew on my Mac, but I can't compile any go source code using it, because the compiler can't find the standard packages:

parser.go:4:10: error: import file 'os' not found

 import "os

 

I tried building the file using these commands (the effect was the same):

gccgo -c parser.go

and

go build -x -compiler gccgo -o parser_gccgo parser.go

WORK=/var/folders/ct/kyccx04s641gsvy_7ff5qx300000gn/T/go-build492002372

mkdir -p $WORK/command-line-arguments/_obj/

cd /Users/tom/Projects/go

gccgo -I $WORK -c -g -m64 -fgo-relative-import-path=_/Users/tom/Projects/go -o $WORK/command-line-arguments/_obj/main.o ./parser.go

The same file builds fine using the standard go compiler.

My 'go env':

GOARCH="amd64"

GOBIN=""

GOCHAR="6"

GOEXE=""

GOHOSTARCH="amd64"

GOHOSTOS="darwin"

GOOS="darwin"

GOPATH="/Users/tom/Projects/go"

GORACE=""

GOROOT="/usr/local/go"

GOTOOLDIR="/usr/local/go/pkg/tool/darwin_amd64"

CC="clang"

GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fno-common"

CXX="clang++"

CGO_ENABLED="1" 

I also tried creating the same variables as my system env variables (using export), but it didn't help. 

Can you guys help me to resolve this problem?

Unfortunately gccgo does not work on Darwin
(http://gcc.gnu.org/PR46986). Sorry.
