                  Fixed issue #171 :: commit

                  0.11.2 has a compatibility feature to accept the ‘old’ and the ‘new’ pchmessagestart, so that 0.9.x nodes can successfully connect to a 0.11.x node.
                  When establishing outgoing connections 0.11.x uses the new pchMessageStart strin only, which is rejected by the 0.9.x nodes

                                  Added depends folder from bitcoin’s tree to build all dependencies. :: commit

                                  Auto build

                                  https://github.com/FeatherCoin/Feathercoin/commit/e69efc079f1055dc5b12be5d41b82f518cd06a5a

                                  depends/README.md

                                   +### Usage
 +
 +To build dependencies for the current arch+OS:
 +
 +    make
 +
 +To build for another arch/OS:
 +
 +    make HOST=host-platform-triplet
 +
 +For example:
 +
 +    make HOST=x86_64-w64-mingw32 -j4
 +
 +A prefix will be generated that's suitable for plugging into Bitcoin's
 +configure. In the above example, a dir named x86_64-w64-mingw32 will be
 +created. To use it for Bitcoin:
 +
 +    ./configure --prefix=`pwd`/depends/x86_64-w64-mingw32
 +
 +Common `host-platform-triplets` for cross compilation are:
 +
 +- `i686-w64-mingw32` for Win32
 +- `x86_64-w64-mingw32` for Win64
 +- `x86_64-apple-darwin11` for MacOSX
 +- `arm-linux-gnueabihf` for Linux ARM 32 bit
 +- `aarch64-linux-gnu` for Linux ARM 64 bit
 +
 +No other options are needed, the paths are automatically configured.
 +
 +Dependency Options:
 +The following can be set when running make: make FOO=bar
 +
 +    SOURCES_PATH: downloaded sources will be placed here
 +    BASE_CACHE: built packages will be placed here
 +    SDK_PATH: Path where sdk's can be found (used by OSX)
 +    FALLBACK_DOWNLOAD_PATH: If a source file can't be fetched, try here before giving up
 +    NO_QT: Don't download/build/cache qt and its dependencies
 +    NO_WALLET: Don't download/build/cache libs needed to enable the wallet
 +    NO_UPNP: Don't download/build/cache packages needed for enabling upnp
 +    DEBUG: disable some optimizations and enable more runtime checking
 +    HOST_ID_SALT: Optional salt to use when generating host package ids
 +    BUILD_ID_SALT: Optional salt to use when generating build package ids
 +
 +If some packages are not built, for example `make NO_WALLET=1`, the appropriate
 +options will be passed to bitcoin's configure. In this case, `--disable-wallet`.
 +
 +Additional targets:
 +
 +    download: run 'make download' to fetch all sources without building them
 +    download-osx: run 'make download-osx' to fetch all sources needed for osx builds
 +    download-win: run 'make download-win' to fetch all sources needed for win builds
 +    download-linux: run 'make download-linux' to fetch all sources needed for linux builds

 +This is a system of building and caching dependencies necessary for building Bitcoin. 
 +There are several features that make it different from most similar systems:
 +
 +### It is designed to be builder and host agnostic
 +
 +In theory, binaries for any target OS/architecture can be created, from a
 +builder running any OS/architecture. In practice, build-side tools must be
 +specified when the defaults don't fit, and packages must be amended to work
 +on new hosts. For now, a build architecture of x86_64 is assumed, either on
 +Linux or OSX.
 +
 +### No reliance on timestamps
 +
 +File presence is used to determine what needs to be built. This makes the
 +results distributable and easily digestable by automated builders.
 +
 +### Each build only has its specified dependencies available at build-time.
 +
 +For each build, the sysroot is wiped and the (recursive) dependencies are
 +installed. This makes each build deterministic, since there will never be any
 +unknown files available to cause side-effects.
 +
 +### Each package is cached and only rebuilt as needed.
 +
 +Before building, a unique build-id is generated for each package. This id
 +consists of a hash of all files used to build the package (Makefiles, packages,
 +etc), and as well as a hash of the same data for each recursive dependency. If
 +any portion of a package's build recipe changes, it will be rebuilt as well as
 +any other package that depends on it. If any of the main makefiles (Makefile, 
 +funcs.mk, etc) are changed, all packages will be rebuilt. After building, the
 +results are cached into a tarball that can be re-used and distributed.
 +
 +### Package build results are (relatively) deterministic.
 +
 +Each package is configured and patched so that it will yield the same
 +build-results with each consequent build, within a reasonable set of
 +constraints. Some things like timestamp insertion are unavoidable, and are
 +beyond the scope of this system. Additionally, the toolchain itself must be
 +capable of deterministic results. When revisions are properly bumped, a cached
 +build should represent an exact single payload.
 +
 +### Sources are fetched and verified automatically
 +
 +Each package must define its source location and checksum. The build will fail
 +if the fetched source does not match. Sources may be pre-seeded and/or cached
 +as desired.
 +
 +### Self-cleaning
 +
 +Build and staging dirs are wiped after use, and any previous version of a
 +cached result is removed following a successful build. Automated builders
 +should be able to build each revision and store the results with no further
 +intervention.

                                            New file build file?
