编译错误的原因是C++编译器对printf函数进行了name mangling,然后找不到重命名后的函数的符号。解决办法就是使用extern "C" 关键字。 //Save file as .cpp and use C++ compiler to compile itextern"C"{intprintf(constchar*format,...); }intmain() { printf("GeeksforGeeks");return0; } 输出结果: d...
然而C++相比C麻烦的一点是即便相同os不同编译器的name mangling算法往往也是不同的[11][12]，这就很讨...

毫无疑问它就是.cpp文件中的say_hello()函数编译之后的名字,这个过程叫做名字修饰(Name Decoration)或名字改编(Name Mangling)。 名字修饰(name decoration),也称为名字重整、名字改编(name mangling),是现代计算机程序设计语言的编译器用于解决由于程序实体的名字必须唯一而导致的问题的一种技术。 为什么C++需要名字修饰...

Because your function prototypes are compiled as C, you can't have overloading of the same function names with different parameters - that's one of the key features of the name mangling of the compiler. It is described as a linkage issue but that is not quite true - you will get error...
I wrapped an extern "C" around the include of the header files to eliminate name mangling. However, I got linker errors for the library functions (undefined references). The C++ project adds an "__imp_" to the name of c functions. So "initModel" becomes "__imp_initModel". Therefore,...
Things to note: - There is two more nightly features used: + The new Rust mangling scheme: we know it will be stable (and the default on, later on). + The binary dep-info output: if we remove all other nightly features, this one can easily go too. - The hack at `exports.c` ...
