Building on mac osx

[robnewton]

I'm trying to follow the readme at https://github.com/xxxajk/esp-open-sdk for setting up the build environment on OSX however I am running into errors. Has anyone set this up to compile on OSX recently that could provide a novice some more up-to-date instructions? I do not use OSX or Linux/Unix very often but would like to test the recent GPIO code I've added.

For instance...
$ brew tap homebrew/dupes
Error: homebrew/dupes was deprecated. This tap is now empty as all its formulae were migrated.

and...
$ brew install binutils coreutils automake wget gawk libtool help2man gperf gnu-sed --with-default-names grep
Error: invalid option: --with-default-names

As a start to try and get around these issues, I have upgraded homebrew, then removed the invalid option from the brew install command based on the following: (it was removed)

Homebrew/homebrew-core@8c4f31e

Created and mounted the case sensitive volume. Cloned the SDK repo. CD to the sdk dir then typed make. Got the following error and fixed it with the following as well based on this: pfalcon/esp-open-sdk#350

The error:
missing required tool: gobjcopy objcopy

Execute this to fix it:
export PATH="/usr/local/opt/binutils/bin:$PATH"

Make made it pretty far but ultimately fails installing ncurses for build...

Unfortunately it looks as though Crosstool-ng no longer supports OSX:

Never could get OSX working however I was able to get up and running quickly with an Ubuntu VirtualBox image from osboxes.org

brew install ncurses
export CPPFLAGS="-I/usr/local/opt/ncurses/include -I/usr/local/opt/gettext/include"
export LDFLAGS="-L/usr/local/opt/gettext/lib -lintl -L/usr/local/opt/ncurses/lib"

fixes this for me
