Issue with homebrew installed libgit2 about git2go HOT 11 CLOSED

Make sure the submodule is in the right version, and don't use go build, as that cannot build libgit2, which git2go needs. See the README.md for building instructions.

@carlosmn this comes back to an issue I am having by trying to compile from homebrew #124 . I am trying to use the homebrew provided version of libgit2 but that does not seem to be working either. I would really appreciate your help on this if you have a moment.

from git2go.

The homebrew version of libgit2 won't help you at buliding git2go. They're different versions with a different API and ABI, which is why git2go has its own copy of the library which it builds.

@carlosmn okay thats fine but then why the cgo issue when just using make install from inside homebrew. Can you please try it and help me debug?

$ brew install jwaldrip/utils/git-get -v --HEAD

I have tried that command, but it doesn't get as far as cgo running. From the double-slash in your output form the other issue, it looks like some variable isn't set properly. Go's build is very sensitive to missing TMPDIR e.g. and will fail with odd messages in that case too.

I'd try running go env in-between the rest of the command to check that there's a sane environment when go is trying to run.

This is the GOENV.

GOARCH="amd64"
GOBIN=""
GOCHAR="6"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH="/private/tmp/git-get-vGF4Ph"
GORACE=""
GOROOT="/usr/local/Cellar/go/1.3.3/libexec"
GOTOOLDIR="/usr/local/Cellar/go/1.3.3/libexec/pkg/tool/darwin_amd64"
CC="clang"
GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fno-common"
CXX="clang++"

@carlosmn can you give it another try?

from git2go.

I do get the same error now, but I still don't know the cause. This is something interacting between cgo and homebrew. There is a lot in the environment that homebrew puts there. Some might be interacting badly with cgo, but I'm not familiar with homebrew's environment or with the cgo details.

My other option is to just ship a precompiled binary or just shell out to "real git" in my program.

This is how i build it on Mac OS X without brew's libxml2.

!#/bin/bash
src=$(IFS=':';p=(${GOPATH}); echo "${p[0]}")/src/github.com/libgit2/git2go
[ -d ${src} ] || exit 1
git clone https://github.com/libgit2/git2go.git ${src} || exit 2
cd ${src} || exit 3
git submodule init || exit 4
git submodule update || exit 5
make && make install
