Failure to build Sage 9.4 on Monterey

[Jeremy Martin]

I am on a brand-new Apple M1 running Monterey 12.0.1.  I just tried to build Sage 9.4 from source.  After installing XCode, command-line tools, Homebrew, I get the following (complete log files attached).

........

Error building Sage.

The following package(s) may have failed to build (not necessarily
during this run of 'make all-start'):

* package:         gmp-6.2.0
  last build time: Jan 28 12:11
  log file:        /Applications/sage-9.4/logs/pkgs/gmp-6.2.0.log

It is safe to delete any log files and build directories, but they
contain information that is helpful for debugging build problems.
WARNING: If you now run 'make' again, the build directory of the
same version of the package will, by default, be deleted. Set the
environment variable SAGE_KEEP_BUILT_SPKGS=yes to prevent this.

9.4 is not known to run on M1.

Try the latest, 9.5.rc4, instead.

Apologies if I'm missing something, but 9.4 appears to be the current version available on sagemath.org and all its mirrors.

Thanks, Dima.  I'm looking for a stable version to use every day, so I guess I need to wait until the official release of 9.5?

I'm no expert on reading install logs but the problem looks like it is about a specific package.

here is a ticket we have for M1 support.

Even with 9.5 you will need some packages from Homebrew to be able to build on M1

Hi Jeremy,

It depends on what you mean by "every day".

If today is included, there is no version that is both a "stable release" and supports the Apple M1.

If "every day" starts at on a day in the future when Sage 9.5 is released, then Sage 9.5 will satisfy your criteria.

Jeremy,

Installing Sage 9.4 on macOS 12 on a Mac with an Apple M1

processor might work using sagemath-forge.

To try it:
```
INSTALL_LOCATION=$HOME  # or your choice of location
SITE='https://github.com'
DIRS='isuruf/sagemath-forge/releases/latest/download'
FILE="sagemath-forge-$(uname)-$(uname -m).sh"
cd $INSTALL_LOCATION
curl -L -O $SITE/$DIRS/$FILE
bash $FILE
```

The script then asks a few questions; answering "yes"

each time might work well.

Once sagemath-forge is installed, the underlying Conda can
be activated or deactivated; activating it changes the PATH to
include `/path/to/sagemath-forge/bin` where the executables

installed by Conda are located.

So, to use the version of Sage installed via Conda:
```
$ conda activate

$ which sage
/path/to/sagemath-forge/bin/sage

$ sage
│ SageMath version 9.4, Release Date: 2021-08-22
│ Using Python 3.8.12. Type "help()" for help.
sage: %colors Linux

sage: 2 * 3 * 337

2022
sage: quit
Exiting Sage (CPU time 0m0.12s, Wall time 0m16.08s).

$ conda deactivate
```

To start Jupyter notebook or JupyterLab:

```

$ conda activate

$ jupyter notebook

$ jupyter lab

$ conda deactivate

```

To make Conda always active, add the line
```
conda activate
```
to a file that gets sourced every time you start a shell
(e.g. in `$HOME/.bash_profile` if you use bash, or in the
zsh corresponding file if you use zsh as your shell).

Hope that works for you.   --Samuel

The binary release of SageMath 9.4 for Intel Macs is reported to work fine with Rosetta.

Thank you for the suggestions.  I will keep trying to install from source and may post again with more questions.

Samuel,

Thanks - that worked.  I appreciate the help.
