[libvirt] libvirt build failure w/GNU make and automake.git (automake regression?)

by Jim Meyering

When I run ./autogen.sh && make, I see this: (this arose because I had the latest automake.git/master tools -- commit c1b83e1af60b866cf5cdeebf77d0275019bad8b2 from today -- early in my path) Generated 3 wrapper functions CC libvirtmod_la-libvirt-override.lo CC libvirtmod_la-typewrappers.lo CC libvirtmod_la-libvirt.lo CC libvirtmod_qemu_la-libvirt-qemu-override.lo CC libvirtmod_qemu_la-typewrappers.lo CC libvirtmod_qemu_la-libvirt-qemu.lo CCLD libvirtmod_qemu.la CCLD libvirtmod.la make[3]: Leaving directory `/h/j/w/co/libvirt/python' Making all in tests make[3]: Entering directory `/h/j/w/co/libvirt/python/tests' make[3]: Nothing to be done for `all'. make[3]: Leaving directory `/h/j/w/co/libvirt/python/tests' make[2]: Leaving directory `/h/j/w/co/libvirt/python' Making all in tests make[2]: Entering directory `/h/j/w/co/libvirt/tests' Makefile:4355: *** Malformed target-specific variable definition. Stop. make[2]: Leaving directory `/h/j/w/co/libvirt/tests' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/h/j/w/co/libvirt' make: *** [all] Error 2 That is because of this automake-generated rule: undefine.log: undefine @p='undefine'; \ b='undefine'; \ $(am__check_pre) $(LOG_DRIVER) --test-name "$$f" \ --log-file $$b.log --trs-file $$b.trs \ $(am__common_driver_flags) $(AM_LOG_DRIVER_FLAGS) $(LOG_DRIVER_FLAGS) -- $(LOG_COMPILE) \ "$$tst" $(AM_TESTS_FD_REDIRECT) The trouble is that "undefine" is an operator in GNU make. Here's that part of GNU make's documentation: 6.9 Undefining Variables ======================== If you want to clear a variable, setting its value to empty is usually sufficient. Expanding such a variable will yield the same result (empty string) regardless of whether it was set or not. However, if you are using the `flavor' (*note Flavor Function::) and `origin' (*note Origin Function::) functions, there is a difference between a variable that was never set and a variable with an empty value. In such situations you may want to use the `undefine' directive to make a variable appear as if it was never set. For example: foo := foo bar = bar undefine foo undefine bar $(info $(origin foo)) $(info $(flavor bar)) This example will print "undefined" for both variables. If you want to undefine a command-line variable definition, you can use the `override' directive together with `undefine', similar to how this is done for variable definitions: override undefine CFLAGS The most pragmatic work-around is to rename the "undefine" test script. However, Stephano, as automake maintainer, I think you will want to fix automake not to prohibit the use of such test names.

[libvirt] 'virsh snapshot-list' throws a segfault [with libvirt-0.9.13-3]

[libvirt] libvirt & git send-email

by Gene Czarcinski

I have (hopefully) figured out how to use git and have submitted three emails: a cover, updates for IPv4 and updates for IPv6 ... in fact, I have done this twice ... once yesterday around noon and again a few minutes ago. I submitted them today because the emails had not appeared on libvir-lst. So, after sending them today my CC appeared and a minute or so later the patches appeared on the mailing list. BUT, these emails were the ones I sent yesterday, are dated such, have yesterday's subject line (today's was very slightly different), and had the Message-id from yesterday. Yes, both yesterday and today, I tested doing the "git send-email" by specifying some different email addresses I have and I, indeed, received two copies (TO and CC). If anyone knows what happened, please tell me. If I screwed something up, I would like to not do it again. The from email address matches the email address that is subscribed to this list so that should not be the problem. If this remains a mystery, so be it. Gene
