* libcxx[abi]: removeRosen Penev2020-12-071-19/+0
| | | | | | | | | | | | This is a neat project, but offers no benefit to OpenWrt. The initial reason for it was to be a replacement for libstdcpp as it is smaller and lacks compatibility for C++98. Unfortunately, compiling several packages with it results in larger ipk sizes. While not a member of the packages feed, this will be moved to packages-abandoned to keep it somewhere.

* libcxx: update to 10.0.0Rosen Penev2020-08-311-2/+2
| | | | | | | | | | | | | | | | | | | Switched to upstream tarballs. Switched to libcxxabi as using libsupc++ is quite wonky. Fixed description. Removed patches. The fixes are cosmetic. Added ssp patch. This one is needed for i386 and powerpc under musl. Compile tested every C++ package in the tree with the exception of several boost packages. There's something broken with boost. Ran tested with gerbera. Signed-off-by: Rosen Penev <rosenp@gmail.com>
* libcxx: Add packageRosen Penev2019-12-231-0/+19
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>
