[BlackBird-BB]

I got the same problem with yours. Do you figure it out?

[BlackBird-BB]

It seems that "libxml2.a" is no longger exist in the folder. So I try to edit build.ninja. Replace "libxml2.a" with libxml2.so. And it seems to work firstly, but It stuck at the final step……

[BlackBird-BB]

O，It doesnot stuck, It's just slow……

[BlackBird-BB]

Still，，，problem
