Golang compile error

Question

Another newbie question which has got me pulling my hair out.

Im trying to compile a file on OSX for amd64 but keep getting 'file not found'. My GOPATH is set and the file exisits.

$GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build -o t1Login.linux t1Login.go # github.com/golang-basic/go-curl /usr/local/go/src/pkg/github.com/golang-basic/go-curl/c-callback.c:2 6c: No such file or directory: stdio.h

its looking for the below package file

import ("github.com/golang-basic/go-curl")

I've checked '/usr/local/go/src/pkg/github.com/golang-basic/go-curl/' and the file is present.

Im really lost guys any help at all would be very much appriciated.

UPDATE******

Hi guys thx for the help...its defently push progress on (INSTALLED xCODE ETC.), however on compile...

GOOS=linux GOARCH=amd64 CGO_ENABLED=1 go build -o t1Login.linux t1Login.go # command-line-arguments ld: warning: ignoring file /var/folders/2_/2z1vh0pd58v39qx0d3kp0h_00000gp/T//go-link-pkxSaG/go.o, file was built for unsupported file format ( 0x7F 0x45 0x4C 0x46 0x02 0x01 0x01 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 ) which is not the architecture being linked (x86_64): /var/folders/2_/2z1vh0pd58v39qx0d3kp0h_00000gp/T//go-link-pkxSaG/go.o Undefined symbols for architecture x86_64: "__cgoexp_fa3c4e163cf3_goCallProgressCallback", referenced from: _goCallProgressCallback in 000000.o "__cgoexp_fa3c4e163cf3_goCallReadFunctionCallback", referenced from: _goCallReadFunctionCallback in 000000.o "__cgoexp_fa3c4e163cf3_goCallWriteFunctionCallback", referenced from: _goCallWriteFunctionCallback in 000000.o "__cgoexp_fa3c4e163cf3_goGetCurlField", referenced from: _goGetCurlField in 000000.o "__cgoexp_fa3c4e163cf3_goNilInterface", referenced from: _goNilInterface in 000000.o "_crosscall2", referenced from: _goGetCurlField in 000000.o _goNilInterface in 000000.o _goCallWriteFunctionCallback in 000000.o _goCallProgressCallback in 000000.o _goCallReadFunctionCallback in 000000.o "_main", referenced from: implicit entry/start for main executable ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) /usr/local/go/pkg/tool/darwin_amd64/6l: running clang failed: unsuccessful exit status 0x100

Did you install xcode command line tools? You need that to build c stuff on osx. — RickyA

You do have the curl package here, but internally it tries to build some c code and that is failing because you are missing header files. — RickyA

You need to use CGO_ENABLED=1 to use C

Also

$GOOS=linux should be $GOOS=darwin when using > MacOS 10.6

The file c-callback.c might be present in /usr/local/go/src/pkg/github.com/golang-basic/go-curl, but:

first the path is strange: /usr/local/go/src/pkg doesn't make sense.
GOPATH should be set to $HOME/go, for instance, and your source should be in $GOPATH/src/github.com/golang-basic/go-curl.
second, the file missing is stdio.h, which means some dev package might be missing in order to complete /usr/include:
- like sudo apt-get install build-essential on Unix,
- or, in your case, Xcode Command Line Tools, as commented by RickyA.

@RickyA good point. I have included your comment in the answer.
