Symlinking them in similar manner causes the build to progress further and further (when keeping the build directory unchanged). It happens for both x86-64 targets and i386 targets. I haven't tested building any other qemu targets so far. Installation is gentoo ~amd64, I'll provide more info as needed. Reproducible: Always Steps to Reproduce: 1. Try to build qemu 2. Observe the build error Actual Results: Build process fails Expected Results: Build process completes.

Created attachment 378642 [details] USE flag configuration attaching my USE flags setup. I've completely reinstalled gentoo from scratch and reproduced this build problem. The qemu-log.c error happens on first qemu-user target that's being built. Building i386 and x86_64 fails on i386 target, building only x86_64 target fails on the same file in x86_64 target.
can't reproduce over here, and apparently no one else is seeing it either ...

Created attachment 380666 [details] build.log.gz Disabling ccache fixed the problem for me.
if you clear your ccache cache and rebuild, does it work ?
Enabled ccache again and tried building with a fresh ccache dir but it didn't work. The log looks similar.
Hitting the same problem on qemu-2.1.0
It also builds correctly with ccache disabled.
We now have versions 2.1.2-r2 and 2.2.0 to test.
Tested 2.1.2-r2 and 2.2.0. They still have the same problem.
I have encountered this but only with CCACHE_BASEDIR="${S}" and the reason is ccache will then convert absolute paths to relative paths but qemu actually has two nested build directories, so the relative paths are not valid in both. So for example build/blockdev.d will contain the following when BASEDIR is in effect: > blockdev.o: ../blockdev.c ../include/sysemu/block-backend.h \ And the target build under build/x86_64-softmmu or similar will depend on ../blockdev.o which in turn will get make to source ../blockdev.d to check its dependencies. Since make always considers paths relative to the current working directory rather than the makefile the path appeared in the relative path to ../blockdev.c is useless. A possible workaround is to add the top level build directory to vpath so make be able to resolve ../blockdev.c
