test.a(test.o): In function `test': test.c:(.text+0x13): undefined reference to `func' collect2: ld returned 1 exit status 因此,我们需要注意,在链接命令中给出所依赖的库时,需要注意库之间的依赖顺序,依赖其他库的库一定要放到被依赖库的前面,这样才能真正避免undefined reference的错误,完成编译链接。
/tmp/ccJjiCoS.o: In function `main': main.cpp:(.text+0x7): undefined reference to `test()' collect2: ld returned 1 exit status 原因就是main.cpp为c++代码,调用了c语言库的函数,因此链接的时候找不到. 解决方法:即在main.cpp中,把与c语言库test.a相关的头文件包含添加一个extern "C"的声明...

Edit & run on cpp.shJul 30, 2017 at 9:52pm jlb (4973) You need to properly qualify that xora() is part of the class and that it is not just a function in the global scope. int decof::xora(int q, int i) But really there is not much point of our class since it doesn...
Then the linker creates the executable by combining the object files (and libraries). If your project is not set to compile every .cpp and link all the results, or if no .cpp provides implementation for function, then you get the undefined reference. Dec...
