From e22b450692a6d02da43a453f24ec057bb5517422 Mon Sep 17 00:00:00 2001 From: Gwenhael Goavec-Merou Date: Wed, 19 Jul 2023 13:57:38 +0200 Subject: [PATCH] package/gnuradio: fix gnuradio python libraries for cross-compile By default, module libraries have a suffix based on cpython version + host architecture: this is fine for a native compile when these libraries are used on the same computer (or similar computers). But when target architecture is not the same python is unable to find libraries due to the wrong suffix and produces unclear errors messages: # python3 Python 3.11.3 (main, Jun 19 2023, 14:15:44) [GCC 11.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> from gnuradio import blocks Traceback (most recent call last): File "/home/xxx/buildroot/output/build/gnuradio-3.10.4.0/gr-blocks/python/blocks/__init__.py", line 18, in ModuleNotFoundError: No module named 'gnuradio.blocks.blocks_python' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "", line 1, in File "/home/xxx/buildroot/output/build/gnuradio-3.10.4.0/gr-blocks/python/blocks/__init__.py", line 22, in ModuleNotFoundError: No module named 'gnuradio.blocks.blocks_python' >>> By adding _PYTHON_SYSCONFIGDATA_NAME="$(PKG_PYTHON_SYSCONFIGDATA_NAME)" at configure time, sysconfig will return correct informations (target architecture) instead of host architecture.
