Which version of mesa is this ? Is this a regression ?

Strange...

The symbols is defined in
include/EGL/eglextchromium.h

with is included via (at least)
include/EGL/eglext.h
src/egl/main/egltypedefs.h
src/egl/main/eglcontext.h
src/egl/main/eglapi.c

I'm assuming that you have some thing that is messing with CFLAGS.

IMHO from the above flags you should only need the prefix and libdir

Missing ${XBUILD} ? Might be worth dropping this one as well.

These seem like libdrm configure flags. Not sure what are they doing here.

What are these doing here ?

Please avoid setting these if they are identical. IIRC there was a bug (automake/autoconf) that was incorrectly setting the cross-compile variable.

If nuking the above does not resolve the problem I would recommend explicitly purging CFLAGS and CPPFLAGS before calling the configure, and bisecting the options to see which one is causing the issue.

Cheers

mesa git and probably a regression.

>I'm assuming that you have some thing that is messing with CFLAGS.

I don't believe the CFLAGS have changed since I last successfully built mesa with them.

export CFLAGS="-m${LIBDIRSUFFIX} -O3 -march=native -pipe"
export CXXFLAGS="${CFLAGS} -fvisibility-inlines-hidden"
export CPPFLAGS="${CXXLAGS} -I${XBUILD}/include -L${XBUILD}/lib${LIBDIRSUFFIX}:${XBUILD}/lib:/usr/lib${LIBDIRSUFFIX}"

I disabled the CFLAGS/CXXFLAGS/CPPFLAGS variables and mesa built successfully.

>Missing ${XBUILD} ? Might be worth dropping this one as well.

Not missing--it is a variable pointing to the installation directory.

>These seem like libdrm configure flags. Not sure what are they doing here.
>What are these doing here ?

The above statements suggest you never used http://cgit.freedesktop.org/xorg/util/modular/plain/build.sh to build all of X.  I assume you are compiling mesa by hand or are on another platform.

>Please avoid setting these if they are identical.  IIRC there was a bug (automake/autoconf) that was incorrectly setting the cross-compile variable.

Thanks for the heads up.  Unsetting build/host/target has no effect on the building bug.

My conclusion is that something changed in the mesa code that will not allow me to use my old CFLAGS/CXXFLAGS/CPPFLAGS.

It might take me a while to figure out where in git the change effects the build.

Note that there is typo setting CPPFLAGS ("CXXLAGS"). Also feeding CXXFLAGS to CPPFLAGS can potentially cause problems (?) At least you should see following errors when compiling:

"cc1: warning: command line option '-fvisibility-inlines-hidden' is valid for C++/ObjC++ but not for C [enabled by default]"

(just noticed this when I tried to reproduce the bug)

I would recommend setting PKG_CONFIG_PATH/PKG_CONFIG_LIBDIR which should make the above CPPFLAGS obsolete. Your choice of CPPFLAGS is very hacky imho.

Also as Tapani mentioned CPPFLAGS="${CXXLAGS}... may not be the best of ideas.

AFAIK as one provides a new sysconfdir, the value is independent of PREFIX/EPREFIX. Thus setting it to /etc while the latter two are ${XBUILD} is not something I've seen and/or encourage.

Guilty, I've never used the script as mesa's build has changed substantially since it originated. I use a simple 10-liner script that sets the options that I need from mesa.

Please set PKG_CONFIG_... as suggested above and drop the CPPFLAGS altogether. Mesa's build has always been less than stellar, and allowed people to exploit it to the limits. Recent changes have made things a bit saner.
Comment 5 charlie 2014-06-16 23:45:59 UTC
Solved. Mesa compiled fine after I fixed the typo in CPPFLAGS but I removed CPPFLAGS as suggested anyway.

>I use a simple 10-liner script that sets the options that I need from mesa.

People, your time was not a total waste as I will incorporate all your tips and suggestions I learned here maybe in a build script or .bash_profile so other people can test mesa more easily in the future.

>Thus setting it to /etc while the latter two are ${XBUILD} is not something I've seen and/or encourage.

I probably did that so that I could use one /etc for 3 different installs of X on my system.

Thanks guys.
