Hello I made some progress. We seem to be discussing two issues
1) qemu stops with a segmentation fault. When DEFAULTTUNE is "armv7ahf" or "armv7athf" and a binary is compiled with "-static" and the gold linker is used, then the resulting binary does not run on qemu or on real hardware. The Angstrom distribution by default uses gold, so the issue presents itself when using Angstrom. On the fsl-arm setup with poky gold is not even built so one will not trigger the bug. The solution for this is to change all compiler calls used for qemu run binaries to include -fuse-ld=bfd. 2) qemu runs indefinitely. While hunting the above mentioned bug I found that when using qemu with the sysroot, i.e. using the -L <path-to-sysroot> parameter qemu executes and never returns. On my machine free shows increasingly used RAM but I was to impatient to ever see an OOM kill of qemu but maybe this is also what Colin experiences and probably also why Alex does have issues with the "-L" change. An strace qemu .... run shows that qemu runs in circles of recursive symlink in /usr/lib/udev/ptest/.... files. Using the fsl-arm setup with poky enables ptest. When udev has been compiled in this setup those testfiles have been staged and qemu chokes on them.. http://lists.openembedded.org/pipermail/openembedded-core/2014-September/097098.html a) One way to go would be to fix udev in oe-core, e.g. index 0f8e9b6..a93b58d 100644 --- a/meta/recipes-core/udev/udev/add-install-ptest.patch +++ b/meta/recipes-core/udev/udev/add-install-ptest.patch @@ -21,7 +21,7 @@ Upstream-Status: Pending + sed -i -e 's|^Makefile:|_Makefile:|' $(DESTDIR)/Makefile + $(MKDIR_P) $(DESTDIR)/test + (cd $(top_srcdir) && install $(TESTS) $(DESTDIR)/test) -+ tar -C $(DESTDIR)/test/ -xJf $(top_srcdir)/test/sys.tar.xz ++ cp $(top_srcdir)/test/sys.tar.xz $(DESTDIR)/test/ --- a/test/udev-test.pl 2012-03-18 16:43:36.000000000 +0100 +++ b/test/udev-test.pl 2013-02-18 10:31:29.706357321 +0100 @@ -1459,11 +1459,13 @@ diff --git a/meta/recipes-core/udev/udev/run-ptest b/meta/recipes-core/udev/udev/run-ptest index c6961ce..0e39806 100644 --- a/meta/recipes-core/udev/udev/run-ptest +++ b/meta/recipes-core/udev/udev/run-ptest @@ -1,3 +1,5 @@ #!/bin/sh +tar -C test/ -xJf test/sys.tar.xz make -k check-TESTS +make test-sys-distclean -- 1.8.4.5 b) The quick fix would be to revert passing qemu the sysroot and make sure that all binaries qemu executes are linked statically. As issue 1) now can be addressed without linking dynamically I don't see real disadvantages. revert http://git.yoctoproject.org/cgit/cgit.cgi/meta-java/commit/?id=ab51e51d9a9a51bedd19de09bcba4ce830dfc5e7 c) The even quicker fix is to delete the testdata, i.e. rm -rf <target-sysroot>/usr/lib/udev/ptest/test/sys I will create/send a patch to address issues 1) and 2) solution b).
