Re: Compilation error on openeuler 2003 LTS

Hi,

Thanks for your report.

The enum variable and function has the same name, we will fix soon. The simplest way is to change a name.

No compilation error is reported in my environment. (gcc 7.3) Maybe the two variables appear in the same scope due to "asm/machine_t.h".

I re-check the latest openEuler-1.0-LTS branch, it's ok.

Anyway, we'll send a fix patch soon.
