error log

Hi all, 
    I try to build webkit-r249219 (safari 13, also known as 608.2.11) on new macOS 11.0.1 with Xcode 12.2., while it failed to build, some errors is attached in the attached photo. I can build the latest version webkit with same environment, but when I roll back to older version with "svn update -r 249219", open the xcode project to build, it always fails to build.

    Besides roll back to older version with "svn update -r 249219", do I need to do other steps to sync the dependency or to adjust the xcode project? The errors in my attached photo can be skipped over but will meet another new errors in later building. Or is this failure related to the complier version?

Thanks

There is no expectation that an old version would build on future OS versions.

Thanks, AP. BTW, I use "svn up -r rivision-number" to roll back, is this the correct way?

This is the correct way to get the old revision, yes.
