Hi Aida,
Im sorry again, but I still cannot reproduce your error. I added
your source code into my test project rebuilt again and it works fine in my
computer.
When I have a similar problem like yours, I try to isolate the
problem. I can think on several tests you can do to find where's the
problem:
1. Add the function definition in the header file and check If the
error is still present. I think this should work.
2. Add a new class into your module (QuantiDopaLibLib ) and test the
same behavior to avoid problems with conflicting class names
3. Check if your plugin is linking with the library
QuantiDopaLibLib. You can check it in the properties of the plugin project
and add it to the "Additional Dependencies" to check if it's a dependency
problem
4. Add a new module/plugin with a different name and check if the
error still remains
5. From your processor, call a function of another class of another
library. If it works, try to add your class into this library.
Thanks,
Xavi

Hi Aida,
Im sorry but I cannot reproduce your linking error. I
followed the steps to create a new library and a new plugin and added the
source code you sent me using tl::Template class inside the plugin:
https://sourceforge.net/apps/mediawiki/gimias/index.php?title=HowToCreateYou
rLibrary
https://sourceforge.net/apps/mediawiki/gimias/index.php?title=HowToCreateYou
rPlugin
Could you please send me your source files?, so I can try to
reproduce the error in my computer.
Thanks,
Xavi

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.
Thanks,
Aida

Hi,
Thank you very much for your answer.
I've checked all you have said. I'm new on this, I hope I've checked well as
there are some things that I don't know well.
First of all I have check the macro. What I have is this: class
QUANTIDOPALIB1_0_EXPORT Rec2DFDP. I'm not surt if the macro is the correct
one.
I have also verified the namespace and the correct class before the
function. It seems to be correct. Also, as I type the namespace, then the
class and finally the function, all is being said before finishing each word
by the program. I don't know if this is verifying something.
Just in case, I'm going to generate again the solution.
Thank you very much for your response.

Hi Aida,
First of all, I will answer you in English, if its ok with you,
because in this way, more people can understand your email and give you a
solution for your problem.
The error says that the linker cannot find a function definition.
However the compiler can find the function declaration in compilation time.
This problem seems to be related to the dllexport macro. Could you please
check if you have the correct macro between the class and the name of your
class Rec2DFDP? It should be something like this, but changing the class
name and the macro name:
class DCMAPIDATA_EXPORT Base
All classes exported from a DLL should have this macro.
Another problem could be that the definition of the function
TellHola( ) doesn't match the function declaration. Could you try to verify
that the definition of the function is in the correct namespace and the
correct class?
Best,
Xavi

Hola,
Sóc l'Aida. Treballo amb la Berta i estic desenvolupant funcions pel
QuantiDopa.
He estat treballant amb la Chiara tot aquest temps i m'ha estat donant un
cop de mà perquè pogués començar a desenvolupar les meves funcions.
Durant la setmana passada vam estar, tant amb la Chiara com amb la Berta,
intentant solucionar aquest error:
Error 1 error LNK2019: símbolo externo "__declspec(dllimport) public:
static void __cdecl tl::Rec2DFDP::TellHola(void)"
(__imp_?TellHola@Rec2DFDP@tl@@SAXXZ) sin resolver al que se hace referencia
en la función "public: virtual void __cdecl
ReconstructionPlugin::ReconstructionProcessor::Update(void)"
(?Update@ReconstructionProcessor@ReconstructionPlugin@@UEAAXXZ)
ReconstructionPluginReconstructionProcessor.obj
La Chiara va estar fins i tot amb el Teamviewer en el meu pc per veure què
podia ser el que no estava ben fet. Però després d'estar-ho mirant no hi va
haver manera de solucionar-ho. Em va dir que ja no se li acudia que més
podia ser i em va passar aquesta adreça perquè contactés amb tu.
El que estava fent era una llibreria on tindria tot el codi de les accions
que ha de dur el plugin que vaig crear.
No sé quina informació necessites o si vols que et passi algo del codi, per
poder donar un cop d'ull aquest problema que no em deixa seguir treballant,
però tot el que et faci falta demana-m'ho.
Moltes gràcies,
Aida
