Bug ID: 116237
Summary: gcc does not accept -weak_framework without -Wl on
macOS
Product: gcc
Version: 14.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: vital.had at gmail dot com
CC: iains at gcc dot gnu.org
Target Milestone: ---
Target: *-apple-darwin
gcc does not accept -weak_framework flag passed directly, but that is how MacOS
itself normally uses it.
A random example of the error:

make[2]: *** [rastertobrlaser] Error 1
If changed to -Wl,-weak_framework Kerberos, it works as intended. However, this
is problematic, since MacOS components specify flags without -Wl being added.

I have encountered this error elsewhere too, and assumed that -weak_framework
is just not accepted by the linker: this was incorrect, ld accepts it, but gcc
does not.
