Bug 493568 – app-emulation/qemu-1.6.1[static-user]: with =sys-devel/make-4.0-r1 - ar: two different operation options specified

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Reuben Martin 2013-12-07 21:41:57 UTC]

I was rebuilding app-emulation/qemu-1.6.1 after changing it's use flags to enable "static-user" and it would fail with the following:

ar  libfdt/libfdt.a libfdt/fdt.o libfdt/fdt_ro.o libfdt/fdt_wip.o libfdt/fdt_sw.o libfdt/fdt_rw.o libfdt/fdt_strerror.o
ar: two different operation options specified


It seems that in the makefiles something like ARFLAGS="$(ARFLAGS)" is going on, which sets ARFLAGS=""

Defining ARFLAGS for the ebuild let it build successfully:

ARFLAGS="rv" emerge qemu

Reproducible: Always

1) Please attach the entire build log to this bug report.
2) Please post your `emerge --info app-emulation/qemu' output in a comment.

[Comment 5 Ted Tanberry 2013-12-22 00:23:16 UTC]

As is obvious from the mailing list link Reuben Martin posted, this is a GNU make 4.0 error, that previously relied on some dubious ARFLAGS defaults. I took the patch from that link and tested it, and qemu compiled fine for me.

[Comment 6 Jim Ramsay (lack) (RETIRED) 2014-01-07 14:57:02 UTC]

Reopening as he has provided the info.

I have also verified that adding Ted's attached 'arflags-gmake-4.0.patch' to the 1.6.1 ebuild solves the issue.

this is fixed in at least qemu-2.0.0 which is in the tree now
