1636542 - icecc: Compilation error "use of unknown builtin '__builtin___strlcat_chk'" occurs when compiling sqlite3.c on macOS

Status: RESOLVED INCOMPLETE

(Firefox Build System :: General, defect, P5)

Description

[Jonathan Watt [:jwatt]]

After updating to clang 10, I now get this build error when building with icecc about 7 minutes into the build. It's not clear to me what's going wrong, especially since I don't understand how icecc works given that icecc-create-env doesn't bundle up any headers when creating the toolchain archives. Anyway, filing this so it's on record. The error is:

This doesn't really block bug 1616692, but marking the dependency to make it easier to find this bug.

[(Away)]

Just to confirm [not knowing a whole lot about icecc], the distributed machines are running the same clang 10 that you just installed locally, right?

Comment 2

[Alex Hochheiden [:ahochheiden] (needinfo? me)]

Closing due to inactivity. I'm assuming the problem was probably as speculated above (compiler version mismatch between the distributed machines).
