I searched for any one else having the same issues I found nothing, so here goes.

I was following the instructions to build a native OSX binary at :

https://github.com/micropython/micropyt ... ng-Started

And they didn't work for me. This on OS X 10.11.6 with libffi installed via brew.

To get a working build I used the following steps:

git clone --recurse-submodules https://github.com/micropython/micropython.git
cd micropython/unix
export PKG_CONFIG_PATH=/usr/local/opt/libffi/lib/pkgconfig
make libffi axtls
make MICROPY_PY_BTREE=0

So I have 3 questions :

Is it expected that you have to turn off the berkley db off to get a successful compile?
Is it expected that you have to make libffi and axtls first ?
Should I update https://github.com/micropython/micropyt ... ng-Started with these extra steps ?

Thanks!

On El Capitan this works for me:

Code: Select all

brew install libffi
brew install pkgconfig
brew install python3

cd micropython/unix
unset CFLAGS
make clean
PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig" LDFLAGS="-L/usr/local/opt/libffi/lib" make axtls
PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig" LDFLAGS="-L/usr/local/opt/libffi/lib" make

Code: Select all

Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.

I am not sure about the CFLAGS bit. All of my ports fail to compile unless I unset it.
