The way that generating firmware descriptor files work is that for every input file, every occurrence of @DATADIR@ within the file is replaced with $(DESTDIR)$(qemu_datadir). This works as long as DESTDIR is empty. But in some cases (e.g. on my Gentoo box), compilation is done in one dir, then the installation is done to another dir and then package manager copies over the installed files. It's obvious that $(DESTDIR) must be ignored otherwise the generated FW descriptor files will refer to old installation directory and ignore --prefix given to ./configure. Steps to reproduce: 1) qemu.git $ mkdir _build _install; cd _build && \ ../configure --prefix=/usr && make && \ make DESTDIR=../_install install 2) Observe wrong path: qemu.git/_build $ grep filename ../_install/usr/share/qemu/firmware/* Signed-off-by: Michal Privoznik <mprivozn@redhat.com> --- Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
