Rosen Penev 856ea2bad3 libcxx: Add package Currently in OpenWrt, there are two libc++: libstdcpp and uClibc++. The former is huge and the latter supports only C++98 with some basic support for C++11. Those C++ versions seem to be specific to the compiler version libcxx supports C++11 and above while being much smaller than libstdcpp. On mt7621, these are the sizes of the ipks that I get: libstdcpp: 460786 libcxx: 182881 uClibc++:67720 libcxx is faster than uClibc++ and is under active development as part of the LLVM project while uClibc++ is effectively dead. This PR modifies uclibc++.mk to expose the make menuconfig option. Further cleanup is beyond the scope of this PR. What that means is, this is not used by default. A g++-libcxx wrapper based on the uClibc++ one was added. Works the same way. Compile tested with all packages that use uclibc++.mk in their Makefiles under mipsel_24kc. kismet fails compilation but that package needs to be cleaned up and updated. Runtime tested with gddrescue, gdisk, dcwapd, bonnie++, and aircrack-ng on a TP-Link Archer C7v2. Signed-off-by: Rosen Penev <rosenp@gmail.com>		4 years ago

 -----------------------------------------------------

This is the buildsystem for the OpenWrt Linux distribution.

To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.

You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.

1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default

2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/

3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.

4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
