This is hopefully the beginning of the long-awaited dissolution of libextra. Using the newly created build infrastructure for building libraries, I decided to move the first module out of libextra. While not being a particularly meaty module in and of itself, the flate module is required by rustc and additionally has a native C dependency. I was able to very easily split out the C dependency from rustrt, update librustc, and magically everything gets installed to the right locations and built automatically. This is meant to be a proof-of-concept commit to how easy it is to remove modules from libextra now. I didn't put any effort into modernizing the interface of libflate or updating it other than to remove the one glob import it had.

# Native libraries built as part of the rust build process
|
|
#
|
|
# This portion of the rust build system is meant to keep track of native
|
|
# dependencies and how to build them. It is currently required that all native
|
|
# dependencies are built as static libraries, as slinging around dynamic
|
|
# libraries isn't exactly the most fun thing to do.
|
|
#
|
|
# This section should need minimal modification to add new libraries. The
|
|
# relevant variables are:
|
|
#
|
|
# NATIVE_LIBS
|
|
# This is a list of all native libraries which are built as part of the
|
|
# build process. It will build all libraries into RT_OUTPUT_DIR with the
|
|
# appropriate name of static library as dictated by the target platform
|
|
#
|
|
# NATIVE_DEPS_<lib>
|
|
# This is a list of files relative to the src/rt directory which are
|
|
# needed to build the native library. Each file will be compiled to an
|
|
# object file, and then all the object files will be assembled into an
|
|
# archive (static library). The list contains files of any extension
|
|
#
|
|
# If adding a new library, you should update the NATIVE_LIBS list, and then list
|
|
# the required files below it. The list of required files is a list of files
|
|
# that's per-target so you're allowed to conditionally add files based on the
|
|
# target.
