From 121ffba74375eae51145daa3a889f88151c7ba02 Mon Sep 17 00:00:00 2001 From: Ross Burton Date: Thu, 14 Nov 2024 21:53:53 +0000 Subject: [PATCH] classes-recipe/cython: handle builds with no .c sources This didn't seem to be possible considering the entire point of Cython is to generate C bindings, but some Python build systems remove the build tree once the wheel has been generated, so we never get to see the sources. As xargs will call the specified command even without any files this results in sed failing. Pass --no-run-if-empty so that this case doesn't result in an error.
