error: 'to_string' is not a member of 'std'Arm-hisiv300-linux-g ++ is c++11 supported, header < string> Also included. Again, error.
Search baidu, it is said that + -std=c++11, but I have added this, still not good, then read a post said that because the tool chain itself does not use the standard c++11 library, resulting in the compilation,
Solution: A Cmakelists. TXT needs to add the following options; The same goes for makefile files;
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
add_definitions(-D_GLIBCXX_USE_C99=1)
Error: unrecognized command line option “-std=c++11”, to solve the problem that ubuntu does not support c++11
The cause of this compilation error is not high enough in the g++ GCC version.
Add the source
$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
$ sudo apt-get updateInstall version 4.8
$ sudo apt-get install gcc-4.8 g++-4.8View the local installation version
$ ls -lh /usr/bin/g++*You should see that 4.6 and 4.8 are shipped.
Switch version
$ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.6
$ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 40 --slave /usr/bin/g++ g++ /usr/bin/g++-4.8
$ sudo update-alternatives --config gcc here select version 4.8 serial number
Check the g++ version again
$ g++ --versionConfirm that the current version is 4.8, the problem has been solved!
