2011-09-01build: sort objects to remove duplicates for linkStefan Hajnoczi1-1/+1
Avoid duplicate object files during the link. There are legitimate cases where a link command-line would include duplicate object files because two independent subsystems both depend on common infrastructure. Use GNU make's $(sort) function to remove duplicate object files from the link command-line.

2011-08-22Improvements to libtool support.Brad1-1/+1
Improvements to the libtool support in QEMU. Replace hard coded libtool in the infrastructure with $(LIBTOOL) and allow overriding the libtool binary used via the configure script.

2011-08-12build: Move QEMU_INCLUDES before QEMU_CFLAGSJiri Denemark1-4/+4
This patch fixes build when any of the include paths from QEMU_CFLAGS contains a header file with similar name to a header file in qemu sources. I hit it with error.h included by qapi/qapi-types-core.h. GCC decided to use /usr/include/alsa/error.h instead of qemu's error.h.

2011-06-14libcacard: add libcacard.la targetAlon Levy1-0/+8
No flag to configure is required. Instead, added a libcacard.la target that is not built by default, only when requested explicitly via: mkdir build cd build ../configure make libcacard.la make install-libcacard Uses libtool to do actual linking of object files and shared library, and installing. Tested only under linux, but supposed to work on other systems as well. If libtool isn't found you get a message complaining about that, only at build time (since it is not a default target I did not add a message at configure time). New build artifacts: .libs subdirectories (at <buildroot> and <buildroot>/libcacard) *.lo files (at same locations as the respective o files) Added %.lo : %.c rule that uses libtool. Updated clean rule to clean up those artifacts. Added specific rule to call dtrace with libtool wrapper (note that because of a current upstream dtrace bug fixed by systemtap b1568fd85 commit the -fPIC flag isn't actually passed on. still current dtrace+libtool produced object links fine). If libtool is missing any of the following targets will complain and exit 1: any subdir: *.lo root and libcacard: libcacard.la, libcacard-instsall Tested to link and load with all tracing backends.

2011-01-14do not pass bogus $(SRC_PATH) include paths to cc during configurePaolo Bonzini1-3/+3
Non-existent -I paths are dropped silently by the compiler, but still it is not polite to pass bogus options. Configure-time tests do not need any include files from the source path, so only include -I flags at make time (when they're properly expanded).

2010-10-23rewrite i386 tests MakefilePaolo Bonzini1-0/+9
1) compute path to i386 compiler from configure. If it is found, run the i386 tests. I use macros so that this approach could be applied for other arches as well. 2) provide an easily extensible way to add tests Most tests fail, but at least "make test" does something meaningful.

2010-05-22Put dependency files in proper subdirJan Kiszka1-1/+1
This seems to resolve subtle breakages of our build system: Dependency files generated for targets like 'dir/foo.o' were saved as 'foo.d'. Now, if there was also a target 'foo.o', one of the dependency file was overwritten. Concrete example: libhw*/macio.o vs. libhw*/ide/macio.o. And this often left a segfaulting build result behind when changing the "wrong" data structures". Fix it by generating proper 'dir/foo.d'.

2010-05-03fix whitespace bogon in some versions of makeNathan Froyd1-1/+1
With three different make binaries I have available, configuring a pristine QEMU tree and attempting to make gives the cryptic: Makefile:27: *** missing separator. Stop. This patch fixes it (presumably because it makes the output of `set-vpath' be an empty string, rather than a bit of whitespace), but I don't understand why this hasn't been a problem for other folks before.

2010-01-08finish VPATH -> vpath translationPaolo Bonzini1-1/+2
This adds a few more vpath suffixes and points the remaining two paths explicitly to $(SRC_PATH) in order to eliminate the VPATH assignment from config-host.mak.

2010-01-08Use vpath directivePaolo Bonzini1-0/+2
The vpath directive has two advantages over the VPATH variable: 1) it allows to skip searching of .o files; 2) the default semantics are to append to the vpath, so there is no confusion between "VPATH=xyz" and "VPATH+=xyz". Since "vpath %.c %.h PATH" is not valid, I'm introducing a wrapper macro to append one or more directories to the vpath.

2010-01-07Drop --whole-archive and static librariesAndreas Färber1-2/+2
Juan has contributed a cool Makefile infrastructure that enables us to drop static libraries completely: Move shared obj-y definitions to Makefile.objs, prefixed {common-,hw-,user-}, and link those object files directly into the executables. Replace HWLIB by HWDIR, specifying only the directory. Drop --whole-archive and ARLIBS in Makefiles and configure. Drop GENERATED_HEADERS dependency in rules.mak, since this rebuilds all common objects after generating a target-specific header; add dependency rules to Makefile and Makefile.target instead. v2: - Don't try to include /config.mak for user emulators - Changes to user object paths ("Quickfix for libuser.a drop") were obsoleted by "user_only: compile everything with -fpie" (Kirill A.

2009-12-03Fix build for mingw32 on windows ($@ in macro)Stefan Weil1-4/+5
Make using mingw32 on windows does not preserve $@ in macros when they are modified using this pattern: target: macro += something This behaviour results in an error when QEMU_CFLAGS containing "-MMD -MP -MT $@" is modified for compilation of source files which use SDL: $@ will expand to nothing, -MT no longer has the correct argument (it will take the next one from the command line) and the build will fail or run with a wrong command line. The problem is fixed by using a new macro QEMU_DGFLAGS which is not modified by a target rule. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-10-06Don't use implicit rules for MakefileJuan Quintela1-0/+12
This remove implicit rules + implicit variables. Explicit rules like the generation of %.h and %.c from %.hx still works as expected. As an added bonus, now the output of make -d is readable. As another added bonus, time spend on Makefiles is way smaller. We run make -j3 in a fully compiled tree, and results are: Before: $ time make -j3 real 0m1.225s user 0m1.660s sys 0m0.253s After: $ time make -j3 real 0m0.422s user 0m0.393s sys 0m0.248s Signed-off-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-01-26build system: Further improve quiet mode (Jan Kiszka)aliguori1-6/+6
Derived from Stuart Brady's patch: Show the target directory as prefix to the current module when building in quiet mode.
