Instead of the /depends/ directory on chocolate-doom.org which nobody
except me can edit. Also define a variable to define the base URL for
the mirrors repo so that we can update it easily when GitHub change
their URLs.
Switch from asmjs-unknown-emscripten for Emscripten builds to using
asmjs-local-emscripten instead. The config.sub script doesn't recognize
the emscripten "CPU type" and throws an error, but changing to *-local-*
instead overrides its normal checks.
The current download URL linked from the front page is unstable, since
it breaks every time a new release is put out. Instead, link to the
/fossils/ directory, which contains all old releases as well as the
current release.
chocolate-doom sdl2-branch no longer depends on SDL2_image as of commit
chocolate-doom/chocolate-doom@7215d13b6c, so remove this dependency
and the SDL2_image package.
Normally we run ./configure from within the build tree, but autotools
now allows doing out-of-tree builds by running configure while cd'ed
to a different directory. Add a config variable `AUTOTOOLS_BUILD_PATH`
to allow this on a per-package basis, and set this for the SDL2
package; SDL2 hg complains when doing in-tree builds because certain
files get clobbered.
Since we're downloading arbitrary executable code from websites and
running it, we should at least have some confidence it's the right
thing we're running.
Download these from the maintainers' websites where possible, and
document in a couple of cases why we're still using the mirror. In the
future we can possibly make an automated/generic mechanism for providing
a mirror for files used by chocpkg.
By default we build the stable variant but provide a user-editable
list of packages which will be built at the latest variant instead.
Rename chocolate-doom-git package to chocolate-doom and have it use
the latest variant for the current Git build.
It's nice to be able to build from source control HEAD, and
especially for packages under than Chocolate Doom itself. As a start,
define "latest" variants for all the SDL2 packages.
Slim down the library as much as possible, and link directly against
libpng rather than searching for it at runtime (so that the OS X
package building code will find libpng correctly).
This is important for pkgdef files like SDL2_mixer which recursively
invoke chocpkg to check if a soft dependent package is installed. In
this case it's important to explicitly prefix the package type to
pass it through to the recursed instance.
Previously a particular package could only ever be installed to target
or native. Instead, allow any package to be installed to either, with
target being the default. Native packages can only ever have native
dependencies, but target packages can depend on native ones in order to
install tools which they need for their build process.
The only place this is needed is when determining the directory name
that the tar file will be extracted to. This can be done by examining
the .tar file name without needing to know the version itself.
