Description Sundeep Kokkonda 2025-04-09 07:12:18 UTC 
The default GCC configuration for riscv32/64 assumes multilib is enabled by default even-though we do not have any multilib on target gcc. It alters the c++ standard header paths to multilib specific subdirs and causes GCC on target fails to compile C++ programs.
There is a patch in upstream for this issue.
https://lists.openembedded.org/g/openembedded-core/message/214333

But the above patch uses '--disable-multilib' option for riscv32&64 and it mostly a workaround instead of a proper fix.
The underlying issue to be identified and should be fixed.

Add Trevor due to his new role as the YP RISCV geek, bump to 5.3-M3.
Comment 2 Randy MacLeod 2026-05-28 13:17:56 UTC 
Bulk move of unassigned 6.0-M* bugs to 6.1-M2.
