[coreboot] Building AMD Persimmon in MinGW

[Wim Vervoorn]

Hello Zheng,

 

I have a working environment now by switching to CygWin. I did not have
the regex issues there.

http://sourceforge.net/projects/gnuwin32/files/regex/2.7/

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,


Wim

Hello Zheng,


Any suggestions where I can find this? I haven't been able to locate it
until now.

You need to find a regex2.dll. Just putting it in folder coreboot is OK.
