Hi3516A -std=c++11 编译报错

本帖最后由 baisheng 于 2019-12-16 15:23 编辑

请教一下各位大佬，我用arm-hisiv300-linux-g++编译bctoolbox-0.5.1。
1. 最开始提示找不到execinfo.h，我从系统目录/usr/local/下的execinfo.h直接拷贝到bctoolbox-0.5.1/include/下，错误消失，随后出现下面的错误。
2. Makefile中CXX_FLAGS已经添加-std=c++11，arm-hisiv300-linux-g++ -v --help显示编译器也支持-std=c++11，但编译时还是会出现如下错误：
  CXX      utils/exception.lo
utils/exception.cc: In function ‘void uncaught_handler()’:
utils/exception.cc:29:2: error: ‘exception_ptr’ is not a member of ‘std’
  std::exception_ptr p = current_exception();
  ^
utils/exception.cc:29:21: error: expected ‘;’ before ‘p’
  std::exception_ptr p = current_exception();
                     ^
utils/exception.cc:31:21: error: ‘p’ was not declared in this scope
   rethrow_exception(p);
                     ^

   rethrow_exception(p);
