[bug] Compiling error on aarch64

[frederikdyrmose]

• Did you find a bug in datatable, or maybe the bug found you? I have developed a compact program which uses the datatable library for its operations. In my local development environment, the program works as expected. However, I'm encountering an issue when preparing for deployment: I cannot successfully install the datatable library on my server, which runs on an aarch64 architecture.

• How to reproduce the bug?

  pip install git+https://github.com/h2oai/datatable

  I get the error:

  #10 210.3       +==== ERRORS & WARNINGS ========
  #10 210.3       |
  #10 210.3       | gcc: error: unrecognized command-line option ‘-m64’
  #10 210.3       |
  #10 210.3       +===============================
  #10 210.3       Error linking `src/datatable/lib/_datatable.cpython-311-aarch64-linux-gnu.so`
  #10 210.3
  #10 210.3       [end of output]

• Your environment? I'm trying to install newest datatable version, inside the newest python docker image on an aarch64 machine.

I managed to find a relatively straightforward solution to the issue. After modifying the file named "ci/ext.py" by commenting out the following specific line of code, the datatable library was able to install and operate without any issues on the server.

ext.compiler.add_linker_flag("-m64")
