Failure building swift lib

Trying to build swift using the basic command: ./utils/build-script --release-debuginfo

Unfortunately getting this error:

I think that you have the wrong points of the LLVM repository checked out - that was a recent API change in LLVM. Changing Label->getText() to Label->getText().str() should fix the issue, though I would verify that you have swift/master checked out on llvm-project and master checked out on swift.

I would also make sure you use update-checkout to get the right source. The draconian option:

./swift/utils/update-checkout --scheme master --reset-to-remote --clean

The reset to remote will do a force reset of branches and --clean will clean any other weird stuff you are seeing. Hope this helps!

Thank you guys for helping me out!

@compnerd you are right, I guess I didn't use the llvm-project fork from apple and used original instead.
@Michael_Gottesman thanks, by combing your both advices it seems to work :slight_smile:
