Hi Gerd,
I'm trying to build qemu 5.1.0-rc0 in Fedora. I'm hitting some issues.
Using this configure line:
./configure --prefix=/usr --libdir=/usr/lib64 --sysconfdir=/etc
--localstatedir=/var --libexecdir=/usr/libexec
--interp-prefix=/usr/qemu-%M --with-pkgversion=qemu-5.1.0-0.1.rc0.fc33
'--extra-ldflags=-Wl,--build-id -Wl,-z,relro -Wl,-z,now'
'--extra-cflags=-O2 -g -pipe -Wall -Werror=format-security
-Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fexceptions
-fstack-protector-strong -grecord-gcc-switches
-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1
-specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic
-fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection'
--enable-trace-backend=dtrace --audio-drv-list=pa,sdl,alsa,oss
--enable-kvm --target-list=x86_64-softmmu --enable-pie --enable-modules
--enable-spice
Build and then run:
$ ./x86_64-softmmu/qemu-system-x86_64 -device \? | grep qxl
Failed to open module:
/home/crobinso/src/qemu/x86_64-softmmu/../hw-display-qxl.so: undefined
symbol: qemu_qxl_io_log_semaphore
That error breaks iotests 127:

Doing a build with every target and running 'make check' will show
undefined symbol errors for other targets with hw-display-qxl too. Most
reference the qxl_io_log call but some are like:
Failed to open module:
/home/crobinso/src/qemu/microblaze-softmmu/../hw-display-qxl.so:
undefined symbol: vga_ioport_read
Also as a side note though I think it's pre-existing: running the test
suite with --enable-modules while there are host installed modules is
very noisy with lots of repetitive warnings like:
Failed to initialize module: /usr/lib64/qemu/audio-oss.so
Note: only modules from the same build can be loaded.
Failed to initialize module: /usr/lib64/qemu/audio-pa.so
Note: only modules from the same build can be loaded.

Failed to initialize module: /usr/lib64/qemu/ui-gtk.so

It would be nice if those could be avoided somehow. Maybe
QEMU_MODULE_DIR can help?
Thanks,
Cole
