====== Mac OSX Compiler Setups ======
===== esp-open-sdk =====
**esp-open-sdk** can be installed almost as described in [[setup-linux-compiler-esp8266|Linux Compiler Setups]]. 

Some problems have been reported if you build the toolchain in a case-insensitive filesystem. To avoid these issues create a case-sensitive volume:

  hdiutil create ~/Desktop/eos.dmg -volname "esp-open-sdk" -size 10g -fs "Case-sensitive HFS+"
  hdiutil mount ~/Desktop/eos.dmg
  cd /Volumes/esp-open-sdk

===== esp-open-sdk with Brew =====

==== Dependencies ====

  brew install gnu-sed --with-default-names
  brew tap homebrew/dupes
  brew install gperf
  brew install grep
  brew install autoconf
  brew install binutils
  brew install gawk
  brew install wget
  brew install automake
  brew install libtool
  brew install help2man

binutils is needed for gobjcopy

gawk is required for overwriting the non-gnu awk in my case
  
If you get the error "configure: error: could not find GNU awk", run

  brew link --overwrite gawk
  
If you get the error "./zconf.hash.c:167:1: error: conflicting types for 'kconf_id_lookup'"

  brew uninstall gperf
  
see: https://github.com/pfalcon/esp-open-sdk/issues/236 for reference
===== esp-open-sdk with MacPorts =====

==== Dependencies ====

  sudo port install gsed gawk binutils gperf grep gettext py-serial wget
  
==== Get the compiler ====

  git clone https://github.com/pfalcon/esp-open-sdk.git --recursive

Note the --recursive option. This will force git to initialize modules.
  
==== Patches ====
These needs to be applied before build.
