Using inlined functions defined in .cpp files and mixing function inlining compiler options in different source files can cause LNK2019. Verify the correct spelling and capitalization is used in both the declaration and the definition, and wherever the symbol is used or called.A function is used but the type or number It doesn't matter where the .lib file is on disk, so if you copied it to the project folder, that won't get it added. You can fix the errors by including the source code file that contains the definitions as part of the compilation. Check This Out

You may have missed to choose the right project type with your actual IDE. If it is not defined at all, the linker generates LNK2019.A build dependency is only defined as a project dependency in the solution. I could get a 32bit grasp.exe linked with the 64bit mjhaptix_user.lib by creating a DEF file with aliases. Common error messages are error LNK2001, error LNK1120, error LNK2019 for MSVS and undefined reference to symbolName for gcc.
