+qemu parallel building error on libcacard.la

+hi,
+
+im building qemu with a large make -j value(9).
+sometimes the build fails because of an error:

+
+Which QEMU version are you building?
+
+In qemu.git/master I can see the dependency on trace/* in
+libcacard/Makefile.
+
+Stefan
+
+
+Version 2.0.0
+
+Isn’t the libcacard Makefile run as a recursive make?
+how do you keep the dependencies between two different makes(libcacard and trace)?

+In qemu.git/master:Makefile I see:

+
+To summarize what I think is the problem:
+Libcacard.la depends on trace/generated*.la files(ibcacard.la: $(libcacard-lobj-y))
+Trace/generated*.o files depends on trace/generated*.la files($(libcacard-obj-y): | $(libcacard-lobj-y))
+Also util depends on generated-*.o files (util-obj-y += generated-events.o)   
+This means when libcacard.la is being build generated-*.o files can be build by the util target.
+I think you should change libcacard.la dependencies to include the o files and not only the la files.
+
+Thanks,

+I did some more experiments and maybe I found the issue.
+I added a two prints to rules.mak:
+%.o: %.c

+In qemu.git/master:Makefile I see:

+Subject: RE: [Qemu-devel] [Bug 1324112] [NEW] qemu parallel building error on libcacard.la
+
+To summarize what I think is the problem:
+Libcacard.la depends on trace/generated*.la files(ibcacard.la: $(libcacard-lobj-y))
+Trace/generated*.o files depends on trace/generated*.la files($(libcacard-obj-y): | $(libcacard-lobj-y))
+Also util depends on generated-*.o files (util-obj-y += generated-events.o)   
+This means when libcacard.la is being build generated-*.o files can be build by the util target.
+I think you should change libcacard.la dependencies to include the o files and not only the la files.

+Thanks,

+I did some more experiments and maybe I found the issue.
+I added a two prints to rules.mak:
+%.o: %.c

+
+This two prints symbolize the end of the file build.

+Libcacard.la has a dependency only to .la files and not .o files.

+In qemu.git/master:Makefile I see:

+
+That doesn't look like recursive make to me, but maybe I'm missing

+  
+  i see the build of generated-events.o in the log  before the ar command.
+  because of the -j it was probably not completed yet.

+
+  
+  must be a race condition in the makefile because of a missing dependency.

+I don't think so:
+libcacard.la: $(libcacard-lobj-y)
+        $(call LINK,$^)
+
+The problem is the libcacard-obj-y target is not required by anything.
+
+Try this on qemu.git/master:
+

+$ make libcacard/vscclient
+libcacard/vscclient.o: In function `do_command':

+
+The Makefile is broken.  I suspect that putting proper dependencies in

+
+Please ignore, the libcacard Makefile is actually supposed to be
+invoked as "make vscclient" from the QEMU root directory.  These
+errors were just caused by a %.o: %.c default make target.

+Since the following commit, libcacard and vscclient no longer link
+against QEMU common code:

+commit fd25c0e6dd1ed2aa932fa7ef814b32457bf270fd
+Author: Michael Tokarev <email address hidden>

+
+    libcacard: replace qemu thread primitives with glib ones
+
+Therefore this bug no longer exists in qemu.git/master and can be closed.
