[Qemu-devel] Buildbot Failures

[Charlie Shepherd]

Hi all,

This is an attempt to do some triaging of the 18 current buildbot 
failures[1].

default_ppc:
http://buildbot.b1-systems.de/qemu/builders/default_ppc/builds/729/steps/compile/logs/stdio
>    LINK  ppc-linux-user/qemu-ppc
> target-ppc/translate.o:(.text+0x53518): undefined reference to `tcg_conqt_i64'
> collect2: ld returned 1 exit status
> make[1]: *** [qemu-ppc] Error 1
> make: *** [subdir-ppc-linux-user] Error 2

This only failed last night, I'm not sure where the reference to 
tcg_conqt_i64 came from but it's a recent commit that could probably be 
bisected.



default_x86_64_rhel61:

This looks like a failure to initialise a socket in tests/libqtest.c, 
possibly due to /tmp/ not being accessible?



default_x86_64_rhel5:

This syntax was introduced in Python 2.5, patch to follow to convert 
this to valid Python 2.4 syntax.



default_openbsd_current (offline):

This has been offline for a few weeks, I wonder if this issue has been 
fixed in master since?


default_openbsd_4.9:
http://buildbot.b1-systems.de/qemu/builders/default_openbsd_4.9/builds/700/steps/test/logs/stdio

Commit b53edf971 broke this, pipe2 is a Linux-specific function. Its 
availability can be tested for with CONFIG_PIPE2.


default_mingw32:
http://buildbot.b1-systems.de/qemu/builders/default_mingw32/builds/698/steps/test/logs/stdio

Commit b53edf971  broke this too - pipe2, O_NONBLOCK and sleep are all 
unavailable on MingGW. The test executables don't run from either 
checking the logs, but getting it compiling would be a good start.


default_i386_macosx (offline)

Is this builder in use? It's been offline for a long time.



block_openbsd_current:
block_openbsd_4.9:
block_mingw32:

The same errors as their non block counterparts.



trivial-patches_x86_64_debian_6_0:

QEMU requires libssh2-1.2.8 - the version this function was added in, so 
the buildslave needs updating to at least this libssh2 version. However 
this should have been caught at ./configure time, either block/ssh.o 
shouldn't be compiled because a suitable libssh2 isn't available or 
./configure should throw an error. There's a check in 
block/Makefile.objs so I'm not sure why this didn't happen, I guess it 
merits further investigation?



xen_x86_64_debian_6_0:
xen_i386_debian_6_0:
http://buildbot.b1-systems.de/qemu/builders/xen_i386_debian_6_0/builds/720/steps/configure/logs/stdio
> ERROR: unknown option --disable-debug-info
This builder is trying to build a 2 year old revision (!), so either 
needs to use a later revision or should be deactivated.

xen_unstable:

> libxenstore.so.3.0: cannot open shared object file: No such file or directory

libxenstore is a QEMU dependency, is it available on this buildslave?
