I have a static library exporting the function
time_t SomeClass::getTime();
After compilation its name is mangled as
?getTime@SomeClass@@QAE_JXZ
When I try to use it, VS returns an error
error LNK2001: unresolved external symbol "public: long __thiscall SomeClass::getTime(void)" (?getTime@SomeClass@@QAEJXZ)
And I don’t know what is wrong. Why the same function is mangled differently? I’ve compiled both projects with the same Visual Studio, class has a single header.
Please, help.
The problem was in difference in
time_tdeclarations. Library means it is 64-bit, but application waits for 32-bit value.The remaining question is “why there is no good documentation for MSVS name mangling”? I’ve read a lot, but didn’t find what is the underline in parameters list.
