Containerized arm64 cython --gdb work around
cython with --gdb option resulted in "segmentation fault" when make
built ldms python module on arm64 (aarch64) containers. This issue does
not appear on x86_64 containers. This patch adds a work around to
only enable cython --gdb option for x86_64 architecture.
@tom95858 sure. Let me make a simple .pyx that reproduce the issue. I think ldms.pyx + ldms code is too complicated to submit to cython.
This was all found on Raspberry Pi, correct? I would like to ensure that this is an issue on Stria, etc... before accepting this.
@tom95858 The problem is found in a containerized Pi4. On containerized x86_64, we don't have this issue. On bare metal machines, both x86_64 and Pi4 do NOT have the issue.
Is there a simple-enough reproducer that we could just turn the reproducer into a configure.ac feature check and assume that code for unhappy containers is also going to be built in the unhappy containers?
@narategithub I get it but this will disable --gdb for all platforms except x86_64. So I'd just like to understand what this does and why not just let it fail on those platforms that are broken. This is really a cython bug right?
@tom95858 I think I'll close this pull request. I think my Pi4 might be wonky. When using Pi4 (Ubuntu 22.04), the current https://github.com/ovis-hpc/ldms-containers cannot even successfully build ovishpc/ldms-dev. So, I switched to Jetson Nano (another arm64 small machine from Nvidia; the OS is based on Ubuntu 18.04), and everything works without this patch. I'll switch this PR to draft to keep the discussion open for now.
