[Qemu-devel] [PATCH 0/4] buildsys: Fix module build for block-iscsi.so

[Fam Zheng <famz@redhat.com>]

We get:

    $ qemu-img
    Failed to open module: /home/fam/build/master/block-iscsi.so: undefined symbol: bitmap_set
    qemu-img: Not enough arguments
    Try 'qemu-img --help' for more information

Because since commit b03c38 (block/iscsi: speed up read for unallocated
sectors), block/iscsi.c calls utils/bitmap.c:bitmap_* functions, which is not
linked to qemu-img nor shared objects.

This series links module objects to libqemuutil.a. That requires -fPIC on the
static library objects. The first patch unifies the dependency path of
util-obj-y to libqemuutil.a by removing individual object list from
libcacard-obj-y, so we can apply -fPIC from libqemuutils.a's object specific
variables.

Also added a travis build task for --enable-modules.
