Error installing Cairo on M1 chip (gmp.h)

[howardpen9]

As you can see, when I try to compile the cairo file, it show with these error. I tried to search on Google but can't find with any ideas. I think it's out of my knowledge, anyone know how to solve this? Thank you.

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.

To make mine more generic, try:

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

Edited!

I would suggest pinning this issue @martriay

[martriay]

Done

[machard]

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

[clacladev]

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

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.

Option 1 worked for me, thank you!
