| Subject: [PATCH] Make sure PKGS= is propogated into the submake for "make |
| deps" |
| |
| When we're doing make deps with "$(CC) -MF", gcc and clang have different |
| behavior, both broken in different ways, which we're hitting because of a |
| missing -I argument for libefivar's includes. On clang, when a header can't |
| be found, it emits a rule with the header as a prerequisite without a path, |
| such as efivar.h here: |
| |
| efibootmgr.o: efibootmgr.c fix_coverity.h efivar.h efiboot.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/list.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/efi.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/unparse_path.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/efibootmgr.h \ |
| error.h |
| |
| Then the build that utilizes that rule will fail to find the |
| prerequisite and tell you something like: |
| |
| make[1]: *** No rule to make target 'efivar.h', needed by 'efibootmgr.o'. Stop. |
| make[1]: Leaving directory '/home/pjones/devel/github.com/efibootmgr/master/src' |
| |
| With gcc, when a header can't be found, it emits a rule without that header |
| as a prerequisite, as such (again with efivar.h): |
| |
| efibootmgr.o: efibootmgr.c fix_coverity.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/list.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/efi.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/unparse_path.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/efi.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/efibootmgr.h \ |
| error.h |
| |
| And then your build will fail if you haven't adjusted CFLAGS to tell it |
| where to find the header. |
| |
| Both of these would be better just erroring, but at least gcc's doesn't |
| insert a *wrong* dependency. |
| |
| This patch adds "PKGS=efivar efibootmgr popt" for all deps under src/. |
| Technically that's overkill, as efibootmgr itself doesn't need popt, but it |
| doesn't hurt anything to have the extra part there. The resulting |
| .efibootmgr.d file has the prerequisites expressed correctly: |
| |
| efibootmgr.o: efibootmgr.c fix_coverity.h /usr/include/efivar/efivar.h \ |
| /usr/include/efivar/efiboot.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/list.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/efi.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/unparse_path.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/efi.h \ |
| /home/pjones/devel/github.com/efibootmgr/master/src/include/efibootmgr.h \ |
| error.h |
| |
| This fixes the issue described in github PR #96 |
