The dependency's version is decreased to version 1.21.3. This is the
version currently used in XCode (on the Mac). Upgrading there is
troublesome.
This partly reverts 2b939cebc7a4eea6ec6adae40c8396f836122940.
Most references to and dependencies on Subversion have been removed.
"+svn" is now "+dev". Files that can't be fixed yet have a FIXME-GIT
comment in them; most of these are in the website tests.
At the moment the flags are determined on the first run and stored in
CMAKE_CXX_FLAGS, CMAKE_CXX_FLAGS_DEBUG and CMAKE_CXX_FLAGS_RELEASE[*].
This was actuall not a good idea, since CMake combines CMAKE_CXX_FLAGS
with the CMAKE_CXX_FLAGS_<BUILD_TYPE>. The problem with this setup is
when the compiler is changed the flags are reset to their defaults and
the user made changes to the flags are lost. The second issue with the
old implementation is that the ENABLE_STRICT_COMPILATION CMake option
must be directly set; changing its value after the initial generation
had no effect.
The change will only set CMAKE_CXX_FLAGS, based on the environment
variable $CXXFLAGS, this is stored in its own variable, named
CXX_FLAGS_USER, in CMake and can be changed later. This flag is only
initialised on the first run. It is also based on the default flags we
use for Wesnoth and the _current_ state of the ENABLE_STRICT_COMPILATION
option. For the transition from the old to the new system the old
CMAKE_CXX_FLAGS are used as initial value for the CXX_FLAGS_USER. This
means no flags are lost, but some extra flags are added, will CMake to
cause a recompilation. So it's advised to regenerate the project files
or change the CXX_FLAGS_USER after CMake as updated the flags.
[*] Note I removed the CFlags since all C based code has been removed,
with the removal of the poolallocator.
Since 2010-12-27T04:03:39Z!ai0867@gmail.com, wesnoth no longer builds (due to duplicate
strings), and it would be a lot of work to fix the build system, so
better drop it.
I'm not sure yet what will be the minimum required version so I used
1.14.8 as shipped with Debian Etch as minimum. The library isn't used
yet but will be soon. Only added autotools support.
(Also some minor tab->spaces changes in the changelog.)
