| Hi Folks,
|
|
|
| just a heads up for anybody using an Apple M1 with the most recent Xcode 14.0.1
|
|
|
| Apple clang 14.0.0 randomly coredumps compiling abc .c files. But not deterministically, restarting ./build_openroad.sh will eventually compile some of them til it finally always coredumps compiling extraUtilMisc.c.
|
|
|
| I was able to compile OpenROAD on this machine before, but not with the latest and greatest Xcode.
|
|
|
| I'm curious whether there are other M1/Xcode users out there with similar experience.

| downgrading the command line tools to 13.4 allows to build the project |
