help with a build-user and build-user-plugin failure

[Claudio Fontana]

Hi Alex,

I am seeing build failures with build-user and build-user-plugin:

https://gitlab.com/hw-claudio/qemu/-/pipelines/220245998

and I am trying to start investigating.

How do I reproduce this locally?

I am trying to run locally the check-tcg rule, but I cannot get it to work.
I managed to work around the problem of static libraries (disabled them),

but then I get:

  BUILD   TCG tests for x86_64-linux-user
  BUILD   x86_64-linux-user guest-tests with cc

Have you seen it before?
Any suggestions? I'm on OpenSUSE Leap 15 SP2.

Ciao,

Claudio

Related to 3fc1aad3864 ("configure: remove unnecessary libm test")
+ tcg tests still not ported to Meson?

Hmm so we certainly need libm for the testcase but I guess this is
failing with a local cross compiler rather than docker? I'm not sure the
global feature test should be relevant for testcases.

Probably it's my attempt to make it work with non-static libm that failed then,

is it supposed to work?

I see mention of BUILD_STATIC there, but it does not seem to actually work for me.

If I use static libm, then it works.
If I uninstall static libm, any attempt to build fails, regardless of whether I pass BUILD_STATIC='n' or so.

Ciao and thanks,

CLaudio

All the test cases themselves should be built as static although I see
we fall back for the case of using a local cross compiler. That normally
only covers the case where the host compiler can also build for 32 bit
for testcases.

Ok, so static build required then, np!

Hi all,

and thanks for the help, after a lot of fiddling and applying your suggestions (and a reboot !?)
now things work.

The only thing I am left seeing (also on master) is with check-tcg:


Remote 'g' packet reply is too long (expected 312 bytes, got 560 bytes): 0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000040008004310000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000010063000000000001006340000000082009207000000000000000000000000000000000000000000000000

a number of times during the test.

Seems not to break anything, but I wonder if it is expected or it would need suppressing?

Thanks again,

Hmm that is a mismatch between a broken multiarch gdb and the test. It
is indeed harmless (that's what the $pc test is for) but unfortunately
very noisy on the build. All distros seem to package things differently
but you can either install gdb-multiarch which configure will prefer
when detecting or build your own gdb and point at it with configure
--gdb=/path/to/gdb

I'm open to a clean way of skipping these tests when we don't have all
the parts we need to run.
