Error installing Cairo on M1 chip (gmp.h) about nile HOT 19 CLOSED

To make mine more generic, try:

CFLAGS=-I`brew --prefix gmp`/include LDFLAGS=-L`brew --prefix gmp`/lib pip install ecdsa fastecdsa sympy

from nile.

This seems to be an issue with the Cairo programming language on apple's M1 computers. I read on the Cairo discord that you were able to solve it. Leaving a few success stories taken from the Cairo discord server for anybody stumbling upon this very problem:

1. @guiltygyoza

Replying to myself for a working solution for M1-chip machine, the key to which is to install the x86 homebrew and use that to install & link gmp

1. Duplicate the terminal app and name it something else e.g. terminal_rosetta; set it to Open using Rosetta . Reference: https://medium.com/swlh/run-x86-terminal-apps-like-homebrew-on-your-new-m1-mac-73bdc9b0f343
2. In terminal_rosetta, open a virtual environment running python 3.7
3. Install the x86 homebrew by running arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)" . It will get installed in /usr/local/
4. Use the x86 brew to install gmp by running /usr/local/bin/brew install gmp
5. Use the x86 brew to link gmp by running /usr/local/bin/brew link gmp
6. Follow the rest of the quickstart tutorial at https://www.cairo-lang.org/docs/quickstart.html

2. @milancermak

in case anyone else runs into this error fatal error: 'gmp.h' file not found when installing the necessary Cairo packages on a M1 Mac, after brew install gmp, try this:
CFLAGS=-I`brew --prefix gmp`/include LDFLAGS=-L`brew --prefix gmp`/lib pip install ecdsa fastecdsa sympy

3. @howardpen9

The python library fastecdsa has the issued in new MacOS or M1 chips I think!! You can't install the latest version. I reinstall the each version until the fastecdsa==1.7.5 to run the code successfully! Finally!

4. myself!

None of the above worked for me :(
So I ended up spinning up a docker instance with ubuntu and installed Cairo in it.

from nile.

I tried the @milancermak solution, but on my macOS Monterey (12.1) on M1, pip is not found, while pip3 is.
So modifying Milan's command to the following, I was then able to pip3 install cairo-lang successfully.

CFLAGS=-I`brew --prefix gmp`/include LDFLAGS=-L`brew --prefix gmp`/lib pip3 install ecdsa fastecdsa sympy

from nile.

I would suggest pinning this issue @martriay

To fix this error:

run this command:
ln -s /opt/homebrew/lib/libcairo.2.dylib .

@milancermak trick fixed it for me.
probably worth editing https://www.cairo-lang.org/docs/quickstart.html#quickstart

from nile.

Got it to work using:

• Pipenv (my preference) but normal venv should be fine
• MacOS's Python 3.8
• @milancermak 's Point 2
• @howardpen9 's fastecdsa==1.7.5

from nile.

I am also using M1 Chip, the command below also works for me

CFLAGS=-I`brew --prefix gmp`/include LDFLAGS=-L`brew --prefix gmp`/lib pip install ecdsa fastecdsa sympy

And me on Mac m1 pro chip

from nile.

Done

To make mine more generic, try:

CFLAGS=-I`brew --prefix gmp`/include LDFLAGS=-L`brew --prefix gmp`/lib pip install ecdsa fastecdsa sympy

Worked for me! Appreciate it.

from nile.

Option 1 worked for me, thank you!

from nile.

fastecdsa==1.7.5

this works for me. thank you so much. but compiling doesnt work :(

from nile.

some kind soul posted this and it works for me https://th0rgal.medium.com/the-easiest-way-to-setup-a-cairo-dev-environment-8f2a63610d46

from nile.

CFLAGS=-Ibrew --prefix gmp/include LDFLAGS=-Lbrew --prefix gmp/lib pip3 install ecdsa fastecdsa sympy

Thanks, I've been trying to figure this out for days. This time it happened

I'm using M1 chip, this works for me, thanks!

Compiling works for me, but not execution. I'm getting the same error as this one here: AntonKueltz/fastecdsa#74 (comment)
Probably will just spin up a docker container, but would love to know if execution works for any of you!

Thx! This worked for me! I ran this command after completely removing python on machine (reinstalling python3.9).
