Hi, I've just followed all the steps of the GimiasUserManual -> Develop your own project for GIMIAS. I've created my own library as it is suggested. I've copied the ’tlFirst’ folder, renamed it (’tlRec2DFDP’), renamed the source and include files (’tlRec2DFDP.cpp’ and ’tlRec2DFDP.h’). I also have included it in the library modules.
When I try to use the funtions of my library from the plugin I've created: tl::Template::Pointer tem = tl::Template::New(); std::cout << "Width: " << tem->GetWidth() << std::endl; One of the errors I get is the folowing one: Error 1 error LNK2019: símbolo externo "public: int __cdecl tl::Template::GetWidth(void) const " (?GetWidth@Template@tl@@QEBAHXZ) sin resolver al que se hace referencia en la función "public: virtual void __cdecl ReconstructionPlugin::ReconstructionProcessor::Update(void)" (?Update@ReconstructionProcessor@ReconstructionPlugin@@UEAAXXZ) ReconstructionPluginReconstructionProcessor.obj So I don't know if I need to do something different in order to build correctly the solution.
