Hi,
I'm trying to build IceCat with the Profile-Guided Optimization,
explained in [1]. I'm doing the compilation with this parameter:
mk_add_options PROFILE_GEN_SCRIPT='$(PYTHON)
$(OBJDIR)/_profile/pgo/profileserver.py'
And during the build I do this:
export MOZ_PGO=1
export DISPLAY=:99
Xvfb -nolisten tcp -extension GLX -screen 0 1280x1024x24 $DISPLAY &
make -f client.mk build
It starts the virtual X (Xvfb) and launch an IceCat instance in order to
generate the profiling data for the compiler. It seems that Xvfb is
running fine (I can see the page http://localhost:8888/), but
compilation stops at this point. Last IceCat releases are built fine.
This is the output I see when it stops:
MOZ_PGO_INSTRUMENTED=1 OBJDIR=obj-x86_64-unknown-linux-gnu
JARLOG_DIR=obj-x86_64-unknown-linux-gnu/jarlog/en-US /usr/bin/python2
obj-x86_64-unknown-linux-gnu/_profile/pgo/profileserver.py 10
args:
['/home/figue/icecat/src/icecat-13.0.1/obj-x86_64-unknown-linux-gnu/dist/icecat/icecat-bin',
'-no-remote', '-profile',
'/home/figue/icecat/src/icecat-13.0.1/obj-x86_64-unknown-linux-gnu/_profile/pgo/pgoprofile/',
'http://localhost:8888/index.html']

It seems that 404 is not important. I tried to build with GCC 4.7 and
4.6. Nothing changed. Tried many variations in the build process and
several machines (i686 and x86_64), but I haven't more ideas. Has anyone
been able to build IceCat with PGO?
Best regards
