Hello --
I am the GNU coreutils package maintainer for OpenBSD.
While updating the OpenBSD package to 9.0, the build errored out while
compiling src/ls.c with the following error message:
src/ls.c:2276:6: error: function-like macro '__GNUC_PREREQ' is not
defined
I noticed that there are some #ifdefs defining and using the macro in
the lib/ directory but clearly the definition is not reaching into src/.
OpenBSD has a __GNUC_PREREQ__ macro defined in <sys/cdefs.h> but not the
__GNUC_PREREQ macro.
If the preprocessor checks and associated pragmas are removed from
src/ls.c then it builds OK. OpenBSD package builders use clang 11.1.0
and clang does not trigger the bogus warnings that these
__GNUC_PREREQ-wrapped pragmas are defending against. Obviously that is
not a universal fix, just a data point.
Once this fix is done, the rest of coreutils-9.0 builds and works OK.
There are no test failures for coreutils-9.0 on
x86_64-unknown-openbsd7.0
Thanks.
