I have two different Macs, one of which compiles gcc10 and one of which does not. �Both are using current pkgsrc.

MacOS 11.1

Xcode 12.4

SDK 11.1

The unsuccessful one is:

MacOS 11.4

Darwin�20.5.0

Xcode�12.5

SDK 11.3

The latter also will not compile gcc8 or gcc9. �Note that I added�OSX_SDK_MAP.11.4=11.3 to mk/platform/Darwin.mk because of the version slew.

All of these gcc package fail when the stage 2 and stage 3 files are compared; otherwise the builds seem to progress fine.

I am not seeing any relevant bulk builds to indicate whether this is a known problem.

I would greatly appreciate any suggestions on how to make this work.

Thank you very much.

Coincidentally, I was just working on this issue, which also affects bootstrap and other packages that require cwrappers.

The SDK version has fallen behind the OS version (again).� My existing trees and new bootstraps started failing after the last routine MacOS updates.� The solution appears to be mapping 11.4 to 11.3 in Darwin.mk:

#
# Apple do not always keep the SDK version in step with the OS version.� When
# that happens add a mapping below, but only within the same OS release major.
#
OSX_SDK_MAP.11.2=������ 11.1
+OSX_SDK_MAP.11.4=������ 11.3
#
OSX_SDK_PATH!=� /usr/bin/xcrun \
������������������� --sdk macosx${OSX_SDK_MAP.${OSX_VERSION}:U${OSX_VERSION}} \
������������������� --show-sdk-path 2>/dev/null || echo /nonexistent

I just completed a successful bootstrap with this patch.� Any concerns about committing it?
