Fatal error: runtime: bsdthread_register error

I installed GO from https://golang.org/dl/ on my Mac. I’m on OS X 10.9.3.

I added these to my .bash_profile:

export GOPATH=$HOME/work
export PATH=$PATH:$GOPATH/bin

I created a first simple GO hello program:

package main
import "fmt"
func main() {
    fmt.Printf("hello, world\n")

When I ran, I got the following error:

fatal error: runtime: bsdthread_register error

Hi Marcos,

Using the ‘-ldflags -linkmode=external’ flags with the ‘go build’ works. But does anyone know how to fix the environment so I don’t have to use the build flags?

Hi Janny,

As stated in the golang-nuts thread have you checked that you don’t have
any intrusion software (antivirus / websense, etc) which is preventing Go
to run correctly?

Yup, this is quite likely to be some AV software installed on your Mac.

Hi @dfc and @marcosnils , we found the problem. The DYLD_LIBRARY_PATH environmental variable was set. Once we exported this to empty value DYLD_LIBRARY_PATH= inside the .bash_profile, the error went away. Thanks for all the help.

This sounds like a bandaid. For all reported cases so far, the cause of this error has been faulty AV software.

I think she was running something but I don’t remember if she uninstalled it. I did tell her if something stopped working to take note of this change we make to her environment. I was just glad to find a solution that did not require the use of those extra flags. Thanks!

McAfee Endpoint is running on my Mac. Unfortunately I don’t have root permission to uninstall it. Thanks everyone for all your help!!
