Godon installation issue (Mac)

[Former user]

I am having an issue installing Godon on my Mac. I followed the instructions here for Mac OS installation using Homebrew, but when I run

curl -L https://bitbucket.org/Davydov/godon/raw/master/bin/install.sh | CC=gcc-7 bash

I get

Package github.com/gonum/blas/cgo is not installed

And it looks like github.com/gonum/blas/cgo is a broken link.

Any idea what I should do? Would it be possible to have a precompiled version for Mac?

Hi,

I’m currently looking into this.

In the meantime, providing builds for Mac wouldn’t be easy. Currently linux builds are generated automatically using the CI pipeline, and Bitbucket doesn’t provide Mac OS build infrastructure. On top of that, in the past I didn’t manage to produce static Mac OS binaries. Meaning that likely binaries won’t run on some systems.

Would it be helpful to provide a Dockerfile? This way godon could be run on mac via docker.

Regarding the broken link, cgo is a subpackage of gonum/blas, so it’s expected that github returns 404.

Hi,

Could you try the following command and let me know if it works:

CGO_FFLAGS="-J $TMPDIR -I $TMPDIR" CGO_LDFLAGS="-framework Accelerate" CC=gcc-11 go install -x bitbucket.org/Davydov/godon/godon@latest

See https://github.com/golang/go/issues/48349 for the context for the -J flag.

Hi Iakov,

Thanks for your response! When I run the above, I get:

mkdir -p $WORK/b087/

cd /Users/cbucao/go/pkg/mod/bitbucket.org/!davydov/godon@v0.0.0-20210913094120-eeaf01fcde0b/optimize

pkg-config --cflags -- nlopt

# pkg-config --cflags  -- nlopt

pkg-config: exec: "pkg-config": executable file not found in $PATH

I think a Dockerfile could be a good idea, if you can provide it.

Thanks!

Best,
Christa

Did you install nlopt via homebrew?

[Christabel Bucao]

Yes, just to check I ran brew install nlopt again, and it says Warning: nlopt 2.7.0 is already installed and up-to-date.

Sorry for the difficulties!

[Iakov Davydov]

Could you try to install pkg-config?
brew install pkg-config

Looks like it works now, thanks a lot!
