kandi X-RAY | dumplib Summary

dumplib is a C++ library. dumplib has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

Dumplib is a helper tool to create import libraries (.lib files) with correct extern "C" name decorations for x86 PE files compiled by MSVC. (This means not x64 because x64 files do not have decorated export names; for x64, see Remarks below.) Its main use is to allow creating import libraries for DLLs for which no import library is available, and to customize existing import libraries, e.g. to remove unwanted exports that cause linker collisions.

Unresolved external symbol even if everything seems OK

QUESTION

Unresolved external symbol even if everything seems OK

Asked 2021-Dec-28 at 13:37

I'm not used to coding on Windows, and I am puzzled with this error on VS.

I am developping a static library libA, another one libB calling some methods in libA, and a program prog calling some methods in libB.

libA compiles without any problems.

Same for libB. The include and lib folders about libA are given to VS, as well as libA.lib as an additional dependency.

For prog, I give the include and lib folders concerning both libA and libB. The two libaries themselves are given as additional dependencies. It compiles, but while linking, I got a couple of errors LNK2001 of the type:

unresolved external symbol "public virtual void __thiscall libA::classA1::methodA1(void)" (?methodA1@classA1@libA@@UEAXXZ) in File libB.lib(classB1.obj)

I did a dumpbin of libB and the symbol ?methodA1@classA1@libA@@UEAXXZ appears many times in the dump file.

...

Finally, I found the problem.

libA and libB were correctly working on Linux, so I didn't understand why I got this problem on Windows.

Turns out that, I don't really know why, but the VS solution file generated by CMake allowed to compile libA with an x86 target architecture, but together with the additional option "/machine x64" in the command line section (Project Properties > Linker (or Librarian for a static library) > Command Line).

I removed this "/machine x64" option, recompiled libA, and now the whole thing compiles and links.
