"Apple does not support statically linked binaries on Mac OS X. A statically linked binary assumes binary compatibility at the kernel system call interface, and we do not make any guarantees on that front. Rather, we strive to ensure binary compatibility in each dynamically linked system library and framework." ~Apple Developer Website

I'm encountering this exact same issue: building for OS X fails without much detail.

Apart from some black magic restrictions to limit the CPU feature set allowed, the only way around this is to build the containers locally on your own machine, which will circumvent the issue.
@karalabe
I'm attempting this workaround right now... It's going to take a while on my sad little laptop, so I figured I'd report this while I waited. Keeping my fingers crossed!
Your xgo project is a huge lifesaver. I'm sincerely grateful for all your work!
Update: It worked! Building the containers locally was the way to go! 👍
Extremely detailed write-up, for anyone who might not be familiar with docker:
-
Git clone karalabe/xgo locally, and change to the
docker/basedir:git clone https://github.com/karalabe/xgo.git cd xgo/docker/base -
Docker build the xgo base container locally:
docker build -t xgo-local-base . -
Determine the latest go-specific image, which uses the base image. As of today,
docker/go-latest/Dockerfilepoints todocker/go-1.5.x/Dockerfilewhich finally points todocker/go-1.5.1/Dockerfile. Change dir fromdocker/basetodocker/go-1.5.1:cd ../go-1.5.1 -
Edit the
Dockerfileto use your newly created base image:vim Dockerfile ## Change `FROM karalabe/xgo-base` ## to `FROM xgo-local-base` -
Docker build the go-specific container locally:
docker build -t xgo-local-go-latest . -
Now you're free to use your locally-built docker container for the
xgocommand.
Just include the flag--image=xgo-local-go-latest:xgo --image=xgo-local-go-latest github.com/target/path

Just a heads up: It works fine on my other Debian Wheezy VM that I set up a few weeks ago, even after doing a fresh
docker pull karalabe/xgo-latest

The interesting thing is that in the first instance (the failing one) Go tries to cross compile with the linux toolchain for osx, whicn obviously won't work. Though I've no clue why it would do that. I'll try and look at it a bit later.

karalabe
commented on July 4, 2024
Ok, I think I know what the issue was. Docker uses fairly new CPUs to build the images, and the OSX build tools are compiled while building the images. So the OSX cross compilers will actually use fairly modern CPU instructions, which will fail if running (the cross compilation) on an old CPU. Apart from some black magic restrictions to limit the CPU feature set allowed, the only way around this is to build the containers locally on your own machine, which will circumvent the issue.

Glad it worked :D So, then indeed the issue is that the OSX cross compiler suite in the docker image assembled by docker hub contains newer CPU instructions, that will plain crash on an older CPU. When I find the time, I'll write up a small section about this in the readme so people will be aware and I'll also try to incorporate your detailed writeup about the needed steps. Thanks a lot for taking the time to experiment with the issue and detail the exact steps other might need. Cheers :)

I tried @harrytruong suggestions and darwin builds are now failing with a different error message.

Btw, I've pushed a osx wrapper fix that should now avoid any native CPU optimisations (i.e. it shoulnd't fail with illegal instruction errors any more). The updates are still building.

commented on July 4, 2024
@karalabe So, we should rebuild our xgo again from our local repo? Or can we use docker's directly? And will it solve the -lcrt0.o problem I am encountering?

I just confirmed that I was able to build @pksunkara's cbind test repo by (1) using my locally built docker image, and also by (2) using @karalabe's latest docker image.
@pksunkara -- try again with the latest docker image? make sure you run docker pull karalabe/xgo-latest first, before running your usual xgo command.
I'm testing the latest docker image against my personal projects now... will report back later. Great work @karalabe!

@harrytruong There seem to be some very strange quirk with running docker on osx. I've got a separate report too about linker errors like the one reported in here, but they never occur on my machine, only reported by people running docker on osx. Also that error (that -s is not recognized) isn't produced by the linux ld, as the gnu ld supports it. So i'm a bit puzzled how the wrong ld is called, or even where the wrong ld comes from.

@harrytruong Weird. I will try again using the latest master branch of xgo and report back. By the way, I am using docker on Ubuntu 15.10. Not OS X.

I have even tried adding the flag --go=1.5.1 and also changing targets to darwin-10.9/amd64. Both are giving the same error.

@pksunkara Remove -ldflags='-extldflags "-static"', there is no static version of crt0.o.

@karalabe I understand that. But I want to build a static binary for darwin. Can we make xgo do that?

I ran into this issue, but how can i build static binaries for everything except darwin within a single xgo call?

@karalabe thank you so much 👍 This single comment saved my day. I didn't get why golang's ld step wouldn't find my library (which I even checked for find -name libasound.so || exit 1). But I didn't compile the static version...
