zmq4

zmq4 copied to clipboard

I'm struggling to resolve the error I received above running tests for zmq4 or when trying to use the zmq.Newsocket function. I've tried to clear everything out and re-install but still receive the version 4.2.5 link error.

First I clear out any references to old code rm -rf $GOPATH/src/github.com/pebbe/ rm -rf $GOPATH/pkg/mod/github.com/pebbe/ rm -rf $GOPATH/pkg/linux_amd64/github.com/pebbe/

Install zeromq package for Arch which provides libzmq pacman -Q zeromq shows zeromq 4.3.3-2

Check libzmq

pkg-config --modversion libzmq
4.3.3

ls -la /usr/lib64/libzmq.*

Install zmq4 go get github.com/pebbe/zmq4

Run tests

cd $GOPATH/src/github.com/pebbe/zmq4/ && go test

Any help is greatly appreciated.

I was able to resolve my issues by running go build -a main.go although I'm not sure why. Any insight is appreciated.

Thanks this helped me resolved the same issue! Now I can get some sleep.
