[wojiushixiaobai]

Version

v22.12.0

Platform

Linux debian 6.1.0-27-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.115-1 (2024-11-01) x86_64 GNU/Linux

Subsystem

Cross-compiling for Linux loongarch64 on a Linux x86_64 machine.

What steps will reproduce the bug?

export 'CXX=ccache /opt/cross-tools/bin/loongarch64-unknown-linux-gnu-g++'

How often does it reproduce? Is there a required condition?

always

What is the expected behavior? Why is that the expected behavior?

Should compile.

What do you see instead?
