Archlinux duo 镜像编译失败

在arch linux下尝试编译duo-buildroot-sdk失败，观察错误日志似乎是与atomic有关，但查找这个库发现是gcc自带的。估计是编译器的问题。有人有解决经验吗？错误日志如下

我在Gentoo也有类似的问题。先安装Ubuntu虚拟机绕过去了。

Hi @EOS,

Same problem here on Debian 12. So far I have been unable to discover where the linker should find __atomic_compare_exchange_1. The reference to this symbol is in middleware/v2/lib/libsys.a but I cannot find the source code to explore and/or fix.

$ nm middleware/v2/lib/libsys.a | grep -B1 -A4 atomic
cvi_vb.o:
                 U __atomic_compare_exchange_1
                 U base_dev_close
                 U CVI_SYS_Mmap
                 U CVI_SYS_MmapCache
                 U CVI_SYS_Munmap

Let me know if you have made progress. I can only proceed by removing the entire middleware/v2/sample/venc and vdec directories.

Thanks!
