_______________________________________________________
Details:
The script config-precomp-test/run-test.sh puts $LIBS before the program which
makes it fail with GCC 9 or later (where -Wl,--as-needed is implied):
$ LC_ALL=C gcc-8 -lobjc config-precomp-test.m
$ LC_ALL=C gcc-9 -lobjc config-precomp-test.m
/usr/bin/ld: /tmp/cczUhnH0.o: in function `main':
config-precomp-test.m:(.text+0x24): undefined reference to `objc_get_class'
/usr/bin/ld: config-precomp-test.m:(.text+0x36): undefined reference to
`objc_msg_lookup'
/usr/bin/ld: /tmp/cczUhnH0.o: in function `__objc_gnu_init':
config-precomp-test.m:(.text+0x59): undefined reference to
`__objc_exec_class'
collect2: error: ld returned 1 exit status
$ LC_ALL=C gcc-9 config-precomp-test.m -lobjc
$
Patch attached.
