Subject: [PATCH v9 8/8] lib/posix_wrap/errno.h: Add __set_errno() macro
Date: Tue, 15 Mar 2022 14:05:45 -0400	[thread overview]
Message-ID: <20220315180545.54989-9-rharwood@redhat.com> (raw)
In-Reply-To: <20220315180545.54989-1-rharwood@redhat.com>

From: Daniel Kiper <daniel.kiper@oracle.com>

$ ./configure --target=x86_64-w64-mingw32 --with-platform=efi --host=x86_64-w64-mingw32
$ make

[...]

cat syminfo.lst | sort | gawk -f ./genmoddep.awk > moddep.lst || (rm -f moddep.lst; exit 1)
__imp__errno in regexp is not defined

This happens because grub-core/lib/gnulib/malloc/dynarray_resize.c and
grub-core/lib/gnulib/malloc/dynarray_emplace_enlarge.c (both are used by
regexp module) from the latest Gnulib call __set_errno() which originally
sets errno variable (Windows builds add __imp__ prefix). Of course it is
not defined and grub_errno should be used instead.
