Hi,
I am a newbie to QEMU and trying to build the virtual-device fuzzer
according to qemu/docs/devel/fuzzing.txt, which says:
---
Configure with (substitute the clang binaries with the version you
installed).
...
CC=clang-8 CXX=clang++-8 /path/to/configure --enable-fuzzing \
--enable-sanitizers
Fuzz targets are built similarly to system/softmmu:
make i386-softmmu/fuzz
This builds ./i386-softmmu/qemu-fuzz-i386
---
But when I did this on my Ubuntu 20.04 x86-64 with qemu-5.2.0-rc0
release code, the make complained it could not find the target:
---
root@iZj6canc2b2vgdozetp9foZ:~/qemu# CC=clang-10 CXX=clang++-10
./configure --enable-fuzzing --enable-sanitizers > configure.log
root@iZj6canc2b2vgdozetp9foZ:~/qemu# make i386-softmmu/fuzz
changing dir to build for make "i386-softmmu/fuzz"...
make[1]: Entering directory '/root/qemu/build'
/usr/bin/ninja build.ninja && touch build.ninja.stamp
ninja: no work to do.
/usr/bin/python3 -B /root/qemu/meson/meson.py introspect --targets --
tests --benchmarks | /usr/bin/python3 -B scripts/mtest2make.py >
Makefile.mtest
make[1]: *** No rule to make target 'i386-softmmu/fuzz'. Stop.
make[1]: Leaving directory '/root/qemu/build'
make: *** [GNUmakefile:11: i386-softmmu/fuzz] Error 2
---
Did I missed something or misunderstood the instructions?
Thanks.
