You will have to poke a bit.

I’d read the definition of `buildGoPackage` now,
which can be found in
`pkgs/development/go-modules/generic/default.nix`.

Another idea would be preConfigure = "set -x"
to make bash output everything it calls.

2017-04-26 Thread Sergey Mironov 
I recently tried to upgrade the go compiler up to 1.8 by
cherry-picking all related commits. The error now looks like the
following:

# github.com/ethereum/go-ethereum/vendor/github.com/karalabe/hid
cgo-dwarf-inference:2:8: error: enumerator value for '__cgo_enum__0'
is not an integer constant
cgo-dwarf-inference:10:8: error: enumerator value for '__cgo_enum__7'
is not an integer constant
cgo-dwarf-inference:18:2: error: initializer element is not constant
cgo-dwarf-inference:18:2: note: (near initialization for '__cgodebug_data[0]')
cgo-dwarf-inference:25:2: error: initializer element is not constant
cgo-dwarf-inference:25:2: note: (near initialization for '__cgodebug_data[7]')

Upstream maintainer pointed out to
https://github.com/golang/go/issues/14669 problem. I've tried adding

preBuild=''
  export CGO_CFLAGS='-O0'
'';

without success..

Regards, Sergey

I had a short fear of sentinent AI robots, but it’s (just?)
a go package.

That’s normal go compile errors.
Are you using a very old version of the go compiler?

Have you tried building it on unstable/master?
You can check out nixpkgs with git
and run `nix-build -A ` from there.

[Nix-dev] For go-wizards: Building the geth using buildGoPackage

2017-04-19 Thread Sergey Mironov 
Hi. I'm trying to build the latest version of the geth package.
Unfortunately, the current (v1.3.0) expression doesn't work anymore,
so I tried to use the buildGoPackage function. The build process
starts but the compiler issues errors listed below, all regarding
github.com/karalade/hid dependency. I'm not a Go expert so may miss
some vital knowledge. Could you please recommend me a possible next
move regarding the problem? Maybe changing Go compiler or specifying
some build flags? Note, I'm using quite old version of nixpkgs so may
miss some newer fix.

Regards,
Sergey
