[Qemu-devel] [PATCH] Fix out-of-tree and cross compile builds for pixman

[Qemu-devel] [PATCH] Fix out-of-tree and cross compile builds for pixman

[Blue Swirl]

Pass the selected set of compile tools (cc, ld, nm, ar, ranlib)
to pixman configure.

Fix out-of-tree compiler paths so that pixman-version.h in build
directory can be found.

Not tested, but aren't there quoting issues here if you're
building with --cc='ccache gcc' ?

Yes. Also configure fails because the variables are not expanded and
directory pixman/pixman does not exist. Funny how it worked earlier.

I struggle with the same issue, and there are more problems caused
by the internal pixman code.

The dependencies are wrong because pixman is built too late:
$(TOOLS) also depends on it. It is not trivial to model them correctly.
IMHO it would be better to build the internal pixman immediately when
QEMU's configure is called. Then QEMU's make can always rely on an
existing pixman.

The internal pixman code is also too old for cross compilations with
MinGW-w64. It already fails when running configure.

Newer versions of pixman compile after a trivial modification which
is needed to avoid redefined symbols:

diff --git a/pixman/pixman-mmx.c b/pixman/pixman-mmx.c
index 1a014fd..723c245 100644
--- a/pixman/pixman-mmx.c

  #  include <xmmintrin.h>
  # else
  /* We have to compile with -msse to use xmmintrin.h, but that causes SSE

More changes are needed to avoid typical MinGW-w64 compiler warnings
(pointer to int conversions without uintptr_t).

Up to now, I did not test the resulting code, so maybe there will be more
surprises.

I was able to get a parallel out-of-tree build to work with the following changes.  I'm not sure if it violates any rules about make features or configure processing.

Unless order only dependencies are not allowed the following should fix the build order for pixman and the tools.

diff --git a/Makefile b/Makefile
index ca14a21..42dcf92 100644

        $(call quiet-command,$(MAKE) $(SUBDIR_MAKEFLAGS) -C pixman V="$(V)" all,)

The following change does the internal pixman configuration during the QEMU configuration.

The upside is that the environment variables get passed to the sub-configure.  Probably still need the Makefile fixes for CC="$(CC)", etc. just in case the pixman configuration dependencies are updated.

The down side is that \$(BUILD_DIR) and \$(SRC_PATH) cannot be used.  Instead I used `pwd` and ${source_path}.  Maybe with some more work the pixman configuration would work using the make variables.

There are some dependencies issues that cause unneeded rebuilds and links but I think those exist despite these changes.

For example libcacard/cutils.d is being included for the top-level make but has relative dependencies ../config-host.h and ../qapi-types.h.  Those dependencies work when the PWD is $(BUILD_DIR)/libcacard but not at the top level $(BUILD_DIR).

The objects that are being unnecessarily rebuild are:
  CC    osdep.o
  CC    cutils.o
  CC    qemu-timer-common.o
  CC    oslib-posix.o

This then results in unneeded relinking.

I'd prefer to not have local patches.  Can you submit the patch to
upstream pixman?  Then we can just switch to a fixed checkout to get w64
going.

I sent three patches which are now in the official pixman git repository,
so we can switch to the next labelled version as soon as it is available
(maybe pixman-0.28.1).

Turned out part of the issue is that having pixman-devel installed
masked some of the build issues of the internal pixman even when
building --without-pixman-system, so my build testing was incomplete.

Pushed test branch:
  git://git.kraxel.org/qemu rebase/pixman

Dependency issue isn't tackled yet, but non-parallel builds are working
fine for me.  Feedback is welcome.

cheers,
  Gerd

Re: [Qemu-devel] [PATCH] Fix out-of-tree and cross compile builds for pixman

[Johnson, Eric]

Sorry, I didn’t let the make finish but I think there will be linking errors with the previous because libpixman-1.a may not be built.

The following changes to Gerd's rebase/pixman branch will completely build (except s390x).
