如何支援-std=c++11
首先查看c++0x_warning.h
$ cat ~/bbndk/target_10_3_1_995/qnx6/usr/include/c++/4.8.3/bits/c++0x_warning.h #error This file requires compiler and library support for the \ ISO C++ 2011 standard. This support is currently experimental, and must be \ enabled with the -std=c++11 or -std=gnu++11 compiler options.
眼尖的使用者應該有看到4.8.3這個版本吧！但是，為何使用-std=c++11時，編譯器還是提示unrecognized command line option '-std=c++11'呢？這是因為NDK裡面竟然藏有4.6.3和4.8.3這兩個版本，但是預設卻是使用4.6.3這個版本，使者者可以使用如下指令看一下：
$ ls -al ~/bbndk/host_10_3_1_12/linux/x86/usr/bin/ntoarmv7-gcc* lrwxrwxrwx 1 steward steward 38 Oct 31 2014 /home/steward/bbndk/host_10_3_1_12/linux/x86/usr/bin/ntoarmv7-gcc -> arm-unknown-nto-qnx8.0.0eabi-gcc-4.6.3 lrwxrwxrwx 1 steward steward 38 Oct 31 2014 /home/steward/bbndk/host_10_3_1_12/linux/x86/usr/bin/ntoarmv7-gcc-4.6.3 -> arm-unknown-nto-qnx8.0.0eabi-gcc-4.6.3 lrwxrwxrwx 1 steward steward 38 Oct 31 2014 /home/steward/bbndk/host_10_3_1_12/linux/x86/usr/bin/ntoarmv7-gcc-4.8.3 -> arm-unknown-nto-qnx8.0.0eabi-gcc-4.8.3 lrwxrwxrwx 1 steward steward 41 Oct 31 2014 /home/steward/bbndk/host_10_3_1_12/linux/x86/usr/bin/ntoarmv7-gcc-ar -> arm-unknown-nto-qnx8.0.0eabi-gcc-ar-4.8.3 lrwxrwxrwx 1 steward steward 41 Oct 31 2014 /home/steward/bbndk/host_10_3_1_12/linux/x86/usr/bin/ntoarmv7-gcc-ar-4.8.3 -> arm-unknown-nto-qnx8.0.0eabi-gcc-ar-4.8.3 lrwxrwxrwx 1 steward steward 41 Oct 31 2014 /home/steward/bbndk/host_10_3_1_12/linux/x86/usr/bin/ntoarmv7-gcc-nm -> arm-unknown-nto-qnx8.0.0eabi-gcc-nm-4.8.3 lrwxrwxrwx 1 steward steward 41 Oct 31 2014 /home/steward/bbndk/host_10_3_1_12/linux/x86/usr/bin/ntoarmv7-gcc-nm-4.8.3 -> arm-unknown-nto-qnx8.0.0eabi-gcc-nm-4.8.3 lrwxrwxrwx 1 steward steward 45 Oct 31 2014 /home/steward/bbndk/host_10_3_1_12/linux/x86/usr/bin/ntoarmv7-gcc-ranlib -> arm-unknown-nto-qnx8.0.0eabi-gcc-ranlib-4.8.3 lrwxrwxrwx 1 steward steward 45 Oct 31 2014 /home/steward/bbndk/host_10_3_1_12/linux/x86/usr/bin/ntoarmv7-gcc-ranlib-4.8.3 -> arm-unknown-nto-qnx8.0.0eabi-gcc-ranlib-4.8.3
因此，如要讓Blackberry NDK編譯器可以支援c++11，只要把所有指到4.6.3的symlink改成指到4.8.3即可，如下指令修改(For ARM)：
$ cd ~/bbndk/host_10_3_1_12/linux/x86/usr/bin/ $ rm ntoarmv7-c++ $ rm ntoarmv7-cpp $ rm ntoarmv7-g++ $ rm ntoarmv7-gcc $ rm ntoarmv7-gcov $ ln -s ntoarmv7-c++-4.8.3 ntoarmv7-c++ $ ln -s ntoarmv7-cpp-4.8.3 ntoarmv7-cpp $ ln -s ntoarmv7-g++-4.8.3 ntoarmv7-g++ $ ln -s ntoarmv7-gcc-4.8.3 ntoarmv7-gcc $ ln -s ntoarmv7-gcov-4.8.3 ntoarmv7-gcov
