Hey all First time trying to build / test numpy main branch, so I'm probably doing something wrong. I brought down main and everything built on the first try. However I'm getting test failures related to meson. Specifically the tests in "python -m pytest numpy/core/tests/test_mem_policy.py" all give errors. The errors seem related to meson and visual studio: *> Visual Studio environment is needed to run Ninja. It is recommended to use Meson wrapper:/Users/douglas.turnbull/ws/numpy/venv/bin/meson compile -C .> ERROR: Could not detect Ninja v1.8.2 or newer* This is an m1 mac with Python 3.11.4. Scrolling up in meson_log.txt I see a linker error: *> ld: symbol(s) not found for architecture arm64* Included system information Project version: undefined C compiler for the host machine: cc (clang 14.0.3 "Apple clang version 14.0.3 (clang-1403.0.22.14.1)") C linker for the host machine: cc ld64 857.1 Host machine cpu family: aarch64 Host machine cpu: aarch64 Snippet from meson log *Detecting Apple linker via: `cc -Wl,-v` -> 1stderr:@(#)PROGRAM:ld PROJECT:ld64-857.1BUILD 23:13:29 May 7 2023configured to support archs: armv6 armv7 armv7s arm64 arm64e arm64_32 i386 x86_64 x86_64h armv6m armv7k armv7m armv7emLibrary search paths: . /opt/homebrew/lib /usr/local/lib /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/libFramework search paths: /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Undefined symbols for architecture arm64: "_main", referenced from: implicit entry/start for main executableld: symbol(s) not found for architecture arm64clang: error: linker command failed with exit code 1 (use -v to see invocation)* Seeing a note recommending gcc in the docs, I'm going to try using gcc rather than clang as next steps.
