[Qemu-devel] [PATCH 00/20] More configure/Makefile cleanups

[quintela@redhat.com]

From: Juan Quintela <quintela@redhat.com>

Hi

More configuration cleanups on top of my previous series.
This one:
- when we test for a library, if we need it, we add the
  library to LIBS after checking. Found that we were checking for 2 xen libraries
  and then adding 3 to LIBS.
- starting moving variables to CPPCFLAGS.
- Big SDL cleanup.  SDL configuration have very old cruft there, from
  testing for target_sofmmu before it was set, to testing for "$sdl" = "yes"
  on the else part of tesing "$sdl" = yes.
- I added a configuration define: CONFIG_NOWIN32, I just needed a way to
  compile files for WIN32 or the rest.  If anyone has a better suggestion
  for th ename, it is welcome.

After this series Makefile is basically clean from logic:

(simple-config-4)$ grep ifdef Makefile
ifdef BUILD_DOCS
ifdef INSTALL_BLOBS
(simple-config-4)$ grep ifndef Makefile
ifndef CONFIG_WIN32

ToDo:
- do the same for Makefile.target
- what to do with CFLAGS/CPPFLAGS.  At this point we have things like:
    sdl.o audio/sdlaudio.o sdl_zoom.o baum.o: CFLAGS += $(SDL_CFLAGS)
  Problem is that SDL_CFLAGS ends on fedora (I guess other unix got similar):
    -I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT
  I felt nervous compling some files with -REENTRANT and other without it.
  Should we use a single CFLAGS for all files?  I would prefer to have a single
  CFLAGS, but it is not my call to make that decision.  What everybody else thinks?

Coments, suggestions?

Later, Juan.

Juan Quintela (20):
  add coreaudio libs at the same place that the rest of the audior
    drivers
  move the decision of using threads or not in audio from Makefile to
    configure
  Add CONFIG_NOWIN32
  Use CONFIG_NOWIN32 previus define to simplify Makefile
  add $fmod_inc to CPPFLAGS
  add SLIRP directory to include list in case it is needed
  fold VNC_TLS_CFLAGS into CPPCFLAGS
  fold VNC_SASL_CFLAGS into CPPCFLAGS
  put together uses of -lvdeplug
  -lz is needed for all binaries, move it to LIBS
  put together uses of xen libraries
  the else part of this test is obsolete We are testing for sdl = yes
    inside the else part of the test if sdl = yes
  sdl_config var is never changed from sdl-config value
  remove old sdl config code that was commented
  define SDL_CFLAGS value when we test for SDL
  target_mmu is defined later, at that point has no value
  use sdl_{cflags,libs} insteaf of calling sdl-config
  Add -lX11 to sdl_libs when needed, and remove sdl_x11 variable
  move SDL mingw32 hack to SDL detection
  move SDL static configuration near SDL detection
