LLVM libc++ for NuttX
I was looking for a C+11 lib to integrated on NuttX for a customer's project because uClibc+ doesn't have the C++11 features they need. Then David suggested me to take a look on LLVM's libcxx.
Finally I integrated libcxx on NuttX in the same way uClibc++ was integrated.
Case you have a STM32F4Discovery board and want to test, just follow these steps:
$ git clone https://bitbucket.org/acassis/libcxx Cloning into 'libcxx'... ...
$ git clone https://bitbucket.org/acassis/nuttx_libcxx Cloning into 'nuttx_libcxx'... ...
$ git clone https://bitbucket.org/nuttx/apps Cloning into 'apps'... ...
$ cd libcxx/ libcxx$ ./install.sh ../nuttx_libcxx Installing LLVM/libcxx in the NuttX source tree Installation suceeded
libcxx$ cd ../nuttx_libcxx/ nuttx_libcxx$ tools/configure.sh stm32f4discovery:libcxx-hello nuttx_libcxx$ make
Flash nuttx.bin in the STM32F4Discovery. Then in the serial console execute:
NuttShell (NSH) nsh>? help usage: help [-v] [<cmd>]
[ cmp free mh sh usleep ? dirname help mv sleep xd basename dd hexdump mw test break echo kill pwd time cat exec ls rm true cd exit mb rmdir uname cp false mkdir set unset
