Re: [coreboot] Building AMD Persimmon in MinGW

Here is the link for regex library.

There are lib and dll in regex-2.7-bin.zip.

Kconfig is a seperated tool. If we want to leverage the regex.c in Kconfig, we need to submit a patch.

Hello, I noticed that KConfig includes the regex.c and .h files to solve this issue. I did the same for nvramtool.exe and now it seems to work. (At least I can build it and run it without errors).  Regards,

Subject: Re: [coreboot] Building AMD Persimmon in MinGW You need to find a regex2.dll. Just putting it in folder coreboot is OK.
