Hi there,

I'm trying to cross-compile from linux with OSX as target but I get the following error

building for OS darwin ARCH amd64
# github.com/keybase/go-keychain
../../../go/pkg/mod/github.com/keybase/[email protected]/corefoundation_1.10.go:9:10: fatal error: 'CoreFoundation/CoreFoundation.h' file not found
#include <CoreFoundation/CoreFoundation.h>
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
# net
/usr/local/go/src/net/cgo_bsd.go:15:72: could not determine kind of name for C.AI_MASK
# os/user
/usr/local/go/src/os/user/getgrouplist_darwin.go:16:11: warning: implicit declaration of function 'getgrouplist' is invalid in C99 [-Wimplicit-function-declaration]

I saw the issue #23 but I don't understand how the PR #20 could fix this issue, that PR "just" add cgo build tag

What I have tried

I've tried the following build commands:

  • GOOS=darwin GOARCH=amd64 go build works without building keychain
  • GOOS=darwin GOARCH=amd64 CGO_ENABLED=1 go build doesn't work, fail withe the above error
  • CC=clang-11 GOOS=darwin GOARCH=amd64 CGO_ENABLED=1 go build doesn't work, fails with the above error
  • CC=clang-11 CXX=clang++-11 GOOS=darwin GOARCH=amd64 CGO_ENABLED=1 go build doesn't work, faisl with the above error

I have part of this solved for you, but I'm here in the issues section to comment on a compile error which could be related to my environment setup. None the less this will get you further along. That error is because golang cannot find the xcode libraries with swift. So you need to install swift then tell go where the libraries and header files are.

I was using ubuntu 20.04, but you should be able to switch out the swift library for 18.04.

so you need

apt-get install -yq wget git build-essential 
apt-get install -yq libpython2.7 libpython2.7-dev
apt-get install -yq llvm libicu-dev clang 

wget -c https://swift.org/builds/swift-5.4.2-release/ubuntu2004/swift-5.4.2-RELEASE/swift-5.4.2-RELEASE-ubuntu20.04.tar.gz
tar -xvf swift-5.4.2-RELEASE-ubuntu20.04.tar.gz
mv swift-5.4.2-RELEASE-ubuntu20.04 /usr/share/swift
export PATH=/usr/local/go/bin:/usr/share/swift/usr/bin:$PATH


GOARCH=amd64
CGO_ENABLED=1
GOOS=darwin
CXX=clang++
CC=clang
CGO_CFLAGS=-I/usr/share/swift/usr/lib/swift
