Description Jiaxun Yang 2021-11-25 20:58:27 UTC 
When I was building​ core master from source on Debian Bullseye arm64, I got:

file core/workdir/UnpackedTarball/python3/LO_lib/_sysconfigdata__linux_aarch64-unknown-linux-gnu.py does not exist in the tarball

This is because python's config.sub removed `-unknown` from the triple. The actual filename is `_sysconfigdata__linux_aarch64-linux-gnu.py`

I workaround it by:

diff --git a/external/python3/ExternalPackage_python3.mk b/external/python3/ExternalPackage_python3.mk
index aa3d8d93d77d..9f49f0994d13 100644

 $(eval $(call gb_ExternalPackage_add_files,python3,$(LIBO_BIN_FOLDER)/python-core-$(PYTHON_VERSION)/lib,\
-       LO_lib/_sysconfigdata__$(python3_MACHDEP)_$(subst i686,i386,$(subst -pc,,$(HOST_PLATFORM))).py \
+       LO_lib/_sysconfigdata__$(python3_MACHDEP)_$(subst i686,i386,$(subst -unknown,,$(subst -pc,,$(HOST_PLATFORM)))).py \
 ))
 endif

And I think it should be fixed in upstream.

Thanks.

Has nothing to do with Base, the database component of LO.

Michael: since it concerns Python, thought you might be interested in this one.

Just for info, searching "unknown" in git history of this file, I found a patch I had done:

So "unknown" was already a pb for me.

Let's put this one to NEW since we got a trace from build failure.
