[llvm-dev] [External] Re: How can I build LLVM with my gcc toolchain exactly
You should check multilib support on your debian system. I don't think gcc has `sys/cdefs.h` packaged.

[llvm-dev] [External] Re: How can I build LLVM with my gcc toolchain exactly
I don't install 'multilib' in my debian system, that's why I want to specify my gcc8 toolchain. Actually, I want to build llvm13 with gcc8 toolchain instead of a host environment. What should be my correct steps? On Tue, Nov 23, 2021, 13:02 <gluokai at gmail.com> wrote: You should check multilib support on your debian system. I don't think gcc has `sys/cdefs.h` packaged.
