[Qemu-devel] [PATCH v2 00/81] More Makefile/configure simplification

[Juan Quintela <quintela@redhat.com>]

Hi

I compiled natively on x86_64 linux and crosscompiled it for windows.
Compilation in a different build directory also works.

v2:
- split CFLAGS into QEMU_CFLAGS and CFLAGS to enable:
  make CFLAGS="-O3" foo.o
  make CFLAGS=""
- We have now LIBS/libs_softmmu/libs_tools
  Everything that is in libs_tools is also in libs_softmmu, namely curl and vde
- We have now LIBS and QEMU_CFLAGS per target
- all *_LIBS have been folded in the right LIBS variable
- All arch/os setup/libs/cflags moved to ./configure
- AUDIO_PT is gone, it setup to linke with -pthread, but the LDFLAGS was used
  only for executables in main Makefile, and none of them use sound.  It was not
  used for the targets, that is where it would make a difference.
- aio is renamed to posix_aio

v1:
- CPPFLAGS is gone, long life to CFLAGS
- Refactor common CFLAGS setup to ./configure
- Use same CFLAGS for all configure tests
- ARCH/OS_CFLAGS/LDFLAGS are gone, we add to CFLAGS as we find more options
- new functions complie_prog() compile_object(), test case compilation is done
  with one function
- LIBS: Start LIBS reorganization, common stuff moved to ./configure
- libs_softmmu created for libraries that are only for softmmu
- moved compilation tests out of the creation of configuration files,
  make things way easier.
- Moved sparc_cpu setup to a single place
- minor cleanups/refactors/.. here and there

Comments?

ToDo:
- move all the handling of options to the start of the file
- change meanining of options to:
  foo="no" -> don't even try
  foo="" -> try to detect, and go with detected result
  foo="yes" -> detect, and if it is not found, just exit with an error message.
     Distributions really want to be able to tell:
     ./configure --enable-kvm --enable-vnc-tls ...
     And if it didn't found anything, just exit.  Packager would sort the right
     BuildRequires at this point.
- Start thinking how to enable/disable drivers

Later, Juan.
