(see manual for options) 生成列表文件 -o outputfile Name the final output file 命名最终输出文件名 --depend dependfile Save 'make' source file dependencies 保留 'make' 源文件依赖 --errors errorsfile Put stderr diagnostics to errorsfile 把标准错误判断放入errorsfile -I dir[,dir] Add dirs to...
一个解决办法是通过改代码,hook__cxa_throw()让每次生成的 coredump 都带上堆栈: https://github.com/gcc-mirror/gcc/blob/master/libstdc%2B%2B-v3/libsupc%2B%2B/cxxabi.h#L616 vim /usr/include/c++/4.8.2/cxxabi.h 看到__cxa_throw的声明。__cxa_throw() 是 libstdc++/libc++ 用于实现 throw ...
后来通过调试,发现原因是bool返回的方法是没有return语句!问题是为啥还能通过编译呢? 列子如下: #include <iostream>classTest {public:boolyes(); };boolTest::yes() { std::cout<<"yes"<<std::endl;//return false;};intmain() { Test*t =newTest;boolr = t->yes(); std::cout<<"yes->"<<...

而std::allocator继承于__gnu_cxx::new_allocator,它的构造函数为 81new_allocator(constnew_allocator&)_GLIBCXX_USE_NOEXCEPT{} 也就是说_Vector_impl只是初始化了start, finish, end_of_storage三个成员变量,__a则是完全无用的。 第二部分 分配空间 ...

如果在调试过程中某些库无法定位到源文件,例如 std::string 组件就定位到了我的编译目录. 像这样: /root/gcc-4.9.3/gcc-build-4.9.3/x86_64-unknown-linux-gnu/libstdc++-v3/include/bits/basic_string.h: No such file or directory /root/gcc-4.9.3/gcc-build-4.9.3/x86_64-unknown-linux-gnu/libstd...
client_proxy client(io_service); client.connect("127.0.0.1", "9000"); std::string result = client.call("translate", "test"); //{"code":0,"result":"TEST"} io_service.run(); } catch (const std::exception& e) { std::cerr << "Exception: " << e.what() << std::endl; } ...
8、d!/n; return 0; iostream.h应改写为 #include 及 std:cout 。 unterminated #if conditional 中文含义:#if 语句条件没有终止 错误原因:缺少 #endif 语句 2、编译时的错误信息 variable undeclared (first use in this function) 中文含义:变量variable 没有声明(第一次使用此变量) 解决方法:在使用前声明...
