go: unknown relocation type 42; compiled without -fpic?

[xu-cheng]

From @int03h on April 8, 2016 15:16

Trying to brew install go on debian SID .. (I did try it on testing too) .. it does compile natively on the OS, not problem. ( tried with and without export HOMEBREW_BUILD_FROM_SOURCE=1)

I compiled ethereum-cpp successfully but I can't get GETH ( go version to compile because of it's dependency on golang )

• Ran brew update and retried your prior step?
• Ran brew doctor, fixed as many issues as possible and retried your prior step?
• If you're seeing permission errors tried running sudo chown -R $(whoami) $(brew --prefix)?

I have seen other issues with this error message reported. Try
brew install binutils go
I'm not convinced that will work, but it's worth a shot.

[sjackman]

It looks as though this issue is known upstream. See
golang/go#13114
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=807136

[sjackman]

Maybe my binutils guess is correct. See #1057

Your system linker (/usr/bin/ld) is not up to date with your compiler/assembler. It's not a Go problem at all.

Please report /usr/bin/ld --version

HI thanks for all the help! :)

I did see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=807136 but I assumed that it would be "handled" by brew since it's installed in the native environment - i.e. it is buildable (somehow)

doing a dpkg -l :

ii  go                                     1.6-godeb1                   amd64        Go language compiler and tools (gc)

testing :
brew reinstall binutils go

i.e. it throws the same errors.

root@crunk:/# /usr/bin/ld --version

GNU ld (GNU Binutils for Debian) 2.26

and root@crunk:/# /root/.linuxbrew/bin/ld -v

GNU ld (GNU Binutils) 2.26.20160125

Thanks!

This comment golang/go#13114 (comment) mentions setting the environment variable CGO_ENABLED=0, but I believe that has to be done when compiling go 1.4, and we download a binary of go 1.4, used to bootstrap go 1.5.

[sjackman]

Perhaps I misunderstood though. Try

CGO_ENABLED=0 brew install go

[int03h]

Fixed !

As of go 1.2, a valid GOPATH is required to use the `go get` command:
  https://golang.org/doc/code.html#GOPATH

You may wish to add the GOROOT-based install location to your PATH:
  export PATH=$PATH:/root/.linuxbrew/opt/go/libexec/bin

after setting PATH and logout ..

root@crunk:~# which go
/root/.linuxbrew/bin/go
root@crunk:~# go version
go version go1.6 linux/amd64

Thanks!

[sjackman]

Great!
