+# When invoking a sub-make, keep only the command line variable definitions

+# e.g. invoking:

+#
+# this is because as the GNU make manual says:
+#   The command line variable definitions really appear in the variable
+#   MAKEOVERRIDES, and MAKEFLAGS contains a reference to this variable.
+#
+# and since the GNU make manual also says:

    download-linux: run 'make download-linux' to fetch all sources needed for linux builds

+
+### Android
+
+Before proceeding with an Android build one needs to get the [Android SDK](https://developer.android.com/studio) and use the "SDK Manager" tool to download the NDK and one or more "Platform packages" (these are Android versions and have a corresponding API level).
+In order to build `ANDROID_API_LEVEL` (API level corresponding to the Android version targeted, e.g. Android 9.0 Pie is 28 and its "Platform package" needs to be available) and `ANDROID_TOOLCHAIN_BIN` (path to toolchain binaries depending on the platform the build is being performed on) need to be set.
+
+API levels from 24 to 29 have been tested to work.
+
+If the build includes Qt, environment variables `ANDROID_SDK` and `ANDROID_NDK` need to be set as well but can otherwise be omitted.
+This is an example command for a default build with no disabled dependencies:
+
+    ANDROID_SDK=/home/user/Android/Sdk ANDROID_NDK=/home/user/Android/Sdk/ndk-bundle make HOST=aarch64-linux-android ANDROID_API_LEVEL=28 ANDROID_TOOLCHAIN_BIN=/home/user/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin

+## Build outputs:
+
+In general, the output of a depends package should not contain any libtool
+archives. Instead, the package should output `.pc` (`pkg-config`) files where
+possible.
+
+From the [Gentoo Wiki entry](https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Handling_Libtool_Archives):
+
+>  Libtool pulls in all direct and indirect dependencies into the .la files it
+>  creates. This leads to massive overlinking, which is toxic to the Gentoo
+>  ecosystem, as it leads to a massive number of unnecessary rebuilds.
+
+## Secondary dependencies:
+
+Secondary dependency packages relative to the bitcoin binaries/libraries (i.e.
+those not in `ALLOWED_LIBRARIES` in `contrib/devtools/symbol-check.py`) don't
+need to be shared and should be built statically whenever possible. This
+improves general build reliability as illustrated by the following example:
+
+When linking an executable against a shared library `libprimary` that has its
+own shared dependency `libsecondary`, we may need to specify the path to
+`libsecondary` on the link command using the `-rpath/-rpath-link` options, it is
+not sufficient to just say `libprimary`.
+
+For us, it's much easier to just link a static `libsecondary` into a shared
+`libprimary`. Especially because in our case, we are linking against a dummy
+`libprimary` anyway that we'll throw away. We don't care if the end-user has a
+static or dynamic `libseconday`, that's not our concern. With a static
+`libseconday`, when we need to link `libprimary` into our executable, there's no
+dependency chain to worry about as `libprimary` has all the symbols.
+
+## Build targets:
+
+To build an individual package (useful for debugging), following build targets are available.

+
+    Don't use wingenminiupnpcstrings when generating miniupnpcstrings.h
+
+    The wingenminiupnpcstrings tool is used on Windows to generate version
+    information. This information is irrelevant for us, and trying to use
+    wingenminiupnpcstrings would cause builds to fail, so just don't use it.
+
+    We should be able to drop this once we are using 2.1 or later. See
+    upstream commit: 9663c55c61408fdcc39a82987d2243f816b22932.

+    Disable threading to fix non-determinism
+
+    A bug in the file parser can cause dependencies to be calculated
+    differently based on which files have already been parsed. This is more

+
+    Just disable threading for now. There is no noticable slowdown.

+
+    Fix backwards compatibility with older Freetype versions at runtime
+
+    A few years ago, libfreetype introduced FT_Get_Font_Format() as an alias
+    for FT_Get_X11_Font_Format(), but FT_Get_X11_Font_Format() was kept for abi
+    backwards-compatibility.
+
+    Qt 5.9 introduced a call to FT_Get_Font_Format(). Replace it with FT_Get_X11_Font_Format()
+    in order to remain compatibile with older freetype, which is still used by e.g. Ubuntu Trusty.
+
+    See #14348.

+Author: fanquake <fanquake@gmail.com>

+
+    Remove needless linking against libstdc++
+
+    This is broken for a number of reasons, including:
+    - g++ understands "static-libstdc++ -lstdc++" to mean "link against
+      whatever libstdc++ exists, probably shared", which in itself is buggy.
+    - another stdlib (libc++ for example) may be in use
+
+    See #11981.
