Mac OSX Compiler Setups


esp-open-sdk can be installed almost as described in 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


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 'kconfidlookup'”

brew uninstall gperf

see: for reference

esp-open-sdk with MacPorts


sudo port install gsed gawk binutils gperf grep gettext py-serial wget

Get the compiler

git clone --recursive

Note the –recursive option. This will force git to initialize modules.


These needs to be applied before build.
