Do I have to install the C library on Mac?

[pengyu]

I got the following error when I directly run pip install postal on Mac.

Do I have to manually install the C library? I'd rather not to manually install packages on Mac. Is there a way to make the installation automatic with either include the C library installation in pip or include it in homebrew?

$ pip install postal

For now, you need to install it.

I used the following link as the normal instructions didn't work.

https://github.com/openvenues/libpostal/issues/310

[schen57]

I had the same issue you just need to make sure that the libpostal is installed on your mac: (use the following command and make sure to specify the directory after the "./configure --datadir=" command. Ignore the square bracket and make sure to run the make/sudo make install right after this step as this step will take some time to run

git clone https://github.com/openvenues/libpostal cd libpostal ./bootstrap.sh ./configure --datadir=[...some dir with a few GB of space...] make sudo make install

Unable to install the libpostal library. I got the following error when following your instructions.

what should I do to install it?

The libpostal repo has an additional instruction for mac:

If you're using an M1 Mac, add --disable-sse2 to the ./configure command. This will result in poorer performance but the build will succeed.
