Description Bernhard Wiedemann 2024-04-21 06:55:13 UTC

While working on reproducible builds for openSUSE, I found that
our dlib package build results depend on the build machine's CPU capabilities.

This is likely related to this buildroot diff:

dlib-19.24.4/build/temp.linux-x86_64-cpython-311/CMakeCache.txt
@@ -474,7 +474,7 @@
 PYTHON_LIBRARY:FILEPATH=/usr/lib64/libpython3.11.so

 //Compile your program with AVX instructions
-USE_AVX_INSTRUCTIONS:BOOL=ON
+USE_AVX_INSTRUCTIONS:BOOL=OFF


Please ensure AVX is used consistently - never or always.

Fix was accepted into devel project and is on its way to Factory. Thanks Bernhard for checking that the fix works.

Marking as resolved.
