Debugging Go on OS X

Step 1: Get GDB.

Some of the fancy features Go adds to GDB require GDB >= 7.1. You can check which version you have with gdb -v. If it's high enough, skip to the next section. If not, do the following:

1. Follow these instructions: http://www.opensource.apple.com/source/lldb/lldb-69/docs/code-signing.txt. The name doesn't matter really, but gdb_codesign is as good a choice as any.

2. brew install https://raw.github.com/Homebrew/homebrew-dupes/master/gdb.rb.

Elixir on Erjang

The last few weeks I've spent some night hacking time to get Erjang to be able to run Elixir. Here's a short note on the current status for those interested.

The bottom line is that we can now boot the Elixir REPL, it looks like this:

krab$ ./bin/iex

How to cross compile Go with CGO programs for a different OS/Arch

It is possible to compile Go programs for a different OS, even though go build says otherwise.

You'll need:

• a valid toolchain for the platform/os you're targetting
• Go Tip (works on 1.1 and 1.2rc1 but you might as well be on tip)
• golang-crosscompile helper script https://github.com/davecheney/golang-crosscompile
• the patch provided
