Source: python3.8
Version: 3.8.0~b2-5
Tags: patch
User: debian-cr...@lists.debian.org
Usertags: ftcbfs
python3.8 fails to cross build from source.
The initial failure comes from ./configure which insists that we have a
python3.8 (not any earlier python). A dependency on python3.8:any
<cross> can fix that.
The next failure comes from dtrace as it fails finding sdt headers using
the build architecture compiler. For it to work, CC must be exported.
This could be considered a fault of dtrace. However, exporting CC for
the whole build fixes this aspect.
Some import tests are not conditionalized to DEB_BUILD_OPTIONS=nocheck
and fail.
Finally sysconfigdata-name.diff fails to update one cross
compilation-specific occasion in configure.ac. As a consequence, the
original name is used and the intended file is not created.
After fixing all of these, python3.8 cross builds successfully. Please
consider applying the attached patch.
