Cannot build 10.9.beta9

[Andrew]

I gave up trying to compile 10.9.beta8. When 10.9.beta9 came out I switched to using mamba. Since it is available, I first tried using:

mamba env create --file environment-3.14-macos.yml --name sage-dev
mamba activate sage-dev
pip install --no-build-isolation --editable .

but this did not compile. I thought that I'd read somewhere that there were issues using pytnon 3.14 on macosx, so I then tried:

mamba env create --file environment-3.13-macos.yml --name sage-dev
mamba activate sage-dev
pip install --no-build-isolation --editable .

This also failed. So then I tried using python 3.12:

mamba env create --file environment-3.12-macos.yml --name sage-dev
mamba activate sage-dev
pip install --no-build-isolation --editable .

This also does not build (output below). Between each of these attempts, following https://doc.sagemath.org/html/en/installation/source.html#section-build-source I tried:

• rm src/**/*.so
• find src/sage/ext/interpreters -type f ! -name 'meson.build' -delete
• pip uninstall sage-conf sage-setup sagemath-standard

but this didn't help. Just for fun I also deleted ~/.local/share/mamba

Why are you building libecm and
not installing it from conda?

[Tobia...@gmx.de]

It looks to me the issue is more about the Python installation.

>  fatal error: 'Python.h' file not found
> 19 | #include "Python.h"

The argument 

>  -I/opt/homebrew/include/python3.12

suggests that it tries to use the homebrew-installed python instead of the one from conda. The questions thus are:

1. Does the python3.12 folder contain a Python.h file?

2. Why is meson trying to use the include directory from the homebrew python and not conda. The logs under  /usr/local/src/sage/build/cp312/meson-logs/meson-log.txt might be helpful for this - could you please post them here.

[Andrew]

Thanks for the replies:

> Why are you building libecm and not installing it from conda?

I followed the instructions from https://doc.sagemath.org/html/en/installation/source.html. In particular, as far as I know, I did not build libecm by hand. I thought that conda installed everything in its own virtual environment, automatically taking care of things like this?

Thanks, I didn't know where the meson logs were. 

I just tried a new install using:

mamba env create --file environment-3.12-macos.yml --name sage-dev
mamba activate sage-dev
pip install --no-build-isolation --editable .

This time sage compiled for me. Unfortunately, when I run sage it crashes. I attach the meson log and the crash report. Claude suggests that the problem is with fflas-ffpack and givaro. I tried patching and recompiling gaviaro and friends with 10.9.beta8 but couldn't get it to work. In another post, there was an issue downstream with givaro. Perhaps this is not fixed yet?

[Tobia...@gmx.de]

For further reference, this is the error:

> ImportError: dlopen(/usr/local/src/sage/build/cp312/src/sage/libs/linbox/linbox_flint_interface.cpython-312-darwin.so, 0x0002): symbol not found in flat namespace '__ZN6FFPACK8CharPolyIN6Givaro8Poly1DomINS1_7ModularIddvEENS1_5DenseEEEEERNT_7ElementERKS7_S9_mNS7_8Domain_t11Element_ptrEmRNS7_8Domain_t8RandIterENS_19FFPACK_CHARPOLY_TAGEm'

I'm sorry, I haven't seen this before.

The meson log file shows that many dependencies were cached from a previous run. Maybe try to delete the  sage/build/cp312 folder, and try again.

Sorry for the inconvenience!

[Andrew]

Thanks again. I have already flushed the meson build directories several times, and tried different python versions etc without any success. I think all my issues are due to new  macosx and xcode, which my "university managed" computer forced me to install for "security reasons". There is a discussion of the associated problems, and the attempts to fix them, on sage-release  (see https://groups.google.com/u/1/g/sage-release/c/7e3RjHOqFQA). Using

https://github.com/sagemath/sage/pull/41964
https://github.com/linbox-team/givaro/pull/240

I get a little bit further, but no joy yet. I think that I will just have to wait until someone figures out to get sage to compile with the latest macosx and xcode releases.

[Dima Pasechnik]

I think <https://github.com/sagemath/sage/pull/41626>

might have most or all missing pieces of the puzzle.

Probably only with Accelerate enabled, but I am not sure, I still have no means to test this locally.

[Andrew]

Thanks Dima for looking at this. Using 41625 I initially had compilation errors like:

error: unknown argument: '-MD'

in the linbox_flint_interface compilation, that appeared to be caused by the flags

-Xpreprocessor -fopenmp -lomp ... -Xpreprocessor -MD

I am quite confused, however, as I just tried again with

make distclean && git clean -fd && ./configure && make -j8

and this time sage compiled properly this time. I am happy to send logs and run tests you'd like if this would be helpful.
