Dear Maintainer,
As a workaround until LuaJIT gains support for PowerPC, I propose
building the python-lupa
package with PUC Lua instead of LuaJIT on ppc64 and ppc64el
architectures, where LuaJIT
is not supported.
Proposed changes:
Update debian/control to exclude ppc64 and ppc64el from the LuaJIT build
dependency:
Build-Depends:
libluajit-5.1-dev [!s390x !alpha !hppa !ia64 !m68k !ppc64 !ppc64el
!sh4 !sparc64] | liblua5.1-0-dev,
Apply the attached patch to setup.py, which adds architecture detection
to automatically
select PUC Lua on ppc64 and ppc64el by default.
Rationale:
LuaJIT does not support PowerPC 64-bit architectures and causes
segmentation faults during package tests.
This workaround ensures the package builds successfully on these
architectures while maintaining LuaJIT
usage on supported platforms.
Please review the attached patch and let me know if this approach is
acceptable for resolving the
LuaJIT issue on ppc64 and ppc64el.
Thanks,
Trupti

Dear Maintainer,
pyton-lupa is failed to build on ppc64el with below error:
python-lupa never built on ppc64el. So this bug is of severity
important
at most.
Cheers
