So here's a thought: could we make anv_timestamp.h generation trigger off of libvulkan_intel.so getting rebuilt? I'm not quite sure how one would even do that but it seems like a thing you might be able to do... <div class="gmail_quote">On Jul 6, 2016 8:18 AM, "Emil Velikov" <<a href="mailto:emil.l.velikov@gmail.com">emil.l.velikov@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">From: Emil Velikov <<a href="mailto:emmil.velikov@collabora.com">emmil.velikov@collabora.com</a>> Atm the actual rule will expand to foo.o which is used for static libraries only. Thus the automake manual recommendation [to use OBJEXT] won't help us, since since we're working with a shared library. Thus let's 'demote' the file and add it back to BUILT_SOURCES. This will manage all the complexity for us, at the (existing expense) of working only with the all, check and install targets. The crazy (why the issue was hard to spot): If the dependencies (.deps/*.Plo) are already created one can alter the anv_device.$(OBJEXT) line and/or nuke it all together. That won't lead to any warnings/issues, even though the Makefile is regenerated. Moral of the story: Always rm -rf top_builddir or don't resolve the dependencies manually and use BUILT_SOURCES.
