OS X: setup instructions are wrong

[andrewboie]

brew install cmake ninja dfu-util doxygen qemu dtc python3 gperf curl -O 'https://bootstrap.pypa.io/get-pip.py' ./get-pip.py rm get-pip.py cd ~/zephyr # or to the folder where you cloned the zephyr repo pip3 install --user -r scripts/requirements.txt

The ./get-pip.py line does not work, the script is not executable and requires sudo anyway.

I'll take a look today

[andrewboie]

Crosstool setup has this command, which errors out
`$ brew tap homebrew/dupes

Error: homebrew/dupes was deprecated. This tap is now empty as all its formulae were migrated.`

[andrewboie]

Although it used to be broken, ct-ng in brew works well now in High Sierra. I think we should delete the section about building from source.

[andrewboie]

We should definitely delete the section on "Verifying the Configuration of the Toolchain".
The config files checked into the tree should be in a state where they Just Work if the recommended paths are used.

[andrewboie]

The config files checked into the tree do NOT have the changes in "Verifying the Configuration of the Toolchain" made.
Why is this left as an exercise for the user??

...
CT_LOCAL_TARBALLS_DIR="/Volumes/CrossToolNG/src"
# CT_SAVE_TARBALLS is not set
CT_WORK_DIR="${CT_TOP_DIR}/.build"
CT_PREFIX_DIR="/Volumes/CrossToolNG/x-tools/${CT_TARGET}"
CT_INSTALL_DIR="${CT_PREFIX_DIR}"
# Following options prevent link errors
CT_WANTS_STATIC_LINK=n
CT_CC_STATIC_LIBSTDCXX=n
...

[andrewboie]

OK I'm dead in the water trying to build the toolchain.

[EXTRA]  Preparing working directories
gstat: cannot read file system information for '%Lp': No such file or directory

[andrewboie]

It seems the logic in ct-ng to detect whether gstat works like BSD or GNU is broken.
I hacked it by changing

andrew@magrathea:/usr/local/lib/crosstool-ng-1.23.0
$ ag gstat
scripts/functions
579:                mode="$(gstat -c '%a' "$(dirname "${dir}")")"
582:                mode="$(gstat -f '%Lp' "$(dirname "${dir}")")"

Line 582 to just 'stat' which is the OS X BSD stat tool. Seems to work?

3:02 oh
3:02 i know what the issue is
3:02 you need to run 'make oldconfig'
3:03 the configs you have are probably for Linux and have GNU in them
3:03 'make oldconfig; would reset to BSD
3:03 I remember now, hit this some time ago
3:04 CT_CONFIGURE_has_stat_flavor_GNU=y
3:05 should be CT_CONFIGURE_has_stat_flavor_BSD=y on the mac

[andrewboie]

apboie
3:47 > CT_CONFIGURE_has_stat_flavor_BSD=y
3:47 not as simple as this.
3:48 It is trying to use gstat from brew coreutils as BSD when it is actually GNU
3:48 so it is the opposite.

[andrewboie]

I'm now stuck on #6911

[carlescufi]

There's a lot of stuff in here, let's start with get-pip.py?

[carlescufi]

@andrewboie a first pass at fixing some of the issues you mention: #6949. Should I remove the section you mention, "Verifying the Configuration of the Toolchain"? I haven't tried to build the toolchain yet.
