'undefined reference' means that you are calling that method/function/object, but the linker cannot find it. A few things to check: - is txe_mutex_info_get called with C or C++ name mangling? It could be that it has been compiled with C++, but you are calling it with C nami...

Clang currently doesn't inline method f(void) because of the unprofitability which means that the symbol/reference f is still at the method main. Because the method f(void) doesn't have the extern function specifier, so the compiler doesn't generate the native code for the method f(void)...

That's whatundefined referencemeans. Oct 25, 2014 at 11:19am SuperStinger(84) Yes, Yes I know. I thought that if you declare a function in the .h file, but not provide a definition ( so its still declared ), it will compile fine. Indeed using the function will produce unexpected re...

In the above program, structure C has a static member s that is not accessible to the outside programs. So when we try to assign it a value in the main function, the linker doesn’t find the symbol and may result in an “unresolved external symbol” or “undefined reference”. ...
The “‘png_create_read_struct’ was not declared in this scope” error means that the C/C++ compiler does not know thepng_create_read_structsymbol. It cannot tell whether it is a function, global function pointer or a preprocessor macro. To resolve this error, thepng_create_read_struct(...
试过了上面讲解的方法,只有-Wl,--warn-unresolved-symbol这个参数能够忽略可执行程序编译时的undefined reference的错误(只会给出警告)。 但是由于可执行程序忽略了这个不存在的符号,那么在运行时就会报错: error while loading shared libraries: unexpected PLT reloc type 0x00...
