The above tells us nothing much. Please attach the complete build log from a clean build attempt.

Having the same problem on macOS 12.2.1 (21D62)

I think the problem is pointer misalignment in pas2js:

[kencu (Ken)]

Intel apparently supports unaligned pointers, and fpc uses that to save space.

But xcode warns about it, so the link fails on the warning not being a clean link command.

The solution is at present turn off warnings.

So if all that is accurate, turning off warnings should do it..

[kamischi (Karl-Michael Schindler)]

As little as I know, this is a problem of Xcode 8, which is resolved with Xcode 9. As such it may only affect 10.11, El Capitan. Maybe someone can try -Wl,-max_default_common_align, value with Xcode 8. or -Wl,-w to switch off all warnings.

[ryandesign (Ryan Carsten Schmidt)]

Karl-Michael, both logs in this ticket are from macOS 12 Monterey and the one in duplicate #67958 is from macOS 13 Ventura.

[kamischi (Karl-Michael Schindler)]

The current version (3.2.2_1) fixes this. The issue can be closed.
