    @mrjj said in Snap7 Undefined Reference to TS7Client::TS7Client():

    so press F2 on TS7Client(); and see if it can go there.
    check it doesn't want a param.'

    There is like this parameter.

    class TS7Client
    {
    private:
        S7Object Client;
    public:
    	TS7Client();
    	~TS7Client();
        // Control functions
        int Connect();
        int ConnectTo(const char *RemAddress, int Rack, int Slot);
        int SetCo
    .
    .
    .

      hi
      ok so only have one constructor. and it takes no params.
      Now you need to check if the file is included (the .cpp) in the project.
      (i assumed u included all files in project)

        What I do is add snap7.cpp and snap7.h in project folder and link snap7.lib then compile and intelisense is ok.But I got this error.Also I send this article from author.Maybe better to help.

        1 - use it as external library statically linked (.dll or .so in linux), to do this add snap7.cpp and snap7.h into your source project and add snap7.lib into the external library list (usually it's a linker option) .
        Snap7.cpp defines the objects and snap7.lib contains the binary interface to snap7.dll.
        Use the correct snap7.lib since it must meet your model (32 or 64 bit).
        With this method snap7.dll must be copied into the executable folder of your project.

        2 - embedd snap7 directly into your project at source level. With this method snap7 will be compiled with your project regardless of 32/64 bit architecture, and you dont' need to distribute snap7.dll.
        In this way you dont need of snap7.cpp, snap7.h and snap7.lib, just add to your project the source files needed in accord to this:
        http://snap7.sourceforge.net/snap7_source.html#embed_mc

        As said, snap7 is a standard library, the tasks that you need to do are exactly the same of all other 3th party libraries.
        If you are new of c++/qt programming just do:
        google-->"qt creator external libraries".

          Hi,

          As @aha_1980 suggested: are you linking against the library providing that class ?

                  Which option are you currently using ?

                  Embedding the library or linking to it ?

                  If the later, did you compile it with the same compiler used for Qt ?

                    I didnt understan excatly what you mean.I wanna use link the .lib so that I will use just 3 files .h,.cpp,.lib but I suppose I have to use .dll as well in same file with .lib adding exectuble folder(I doesnt work,like you see Qt create a debug file and .exe after the compile )

                            When I add the source files ,it worked properly.Also this lines is being added,I dont know why

                            win32:LIBS += C:\Qt\Tools\mingw530_32\i686-w64-mingw32\lib\libws2_32.a

                              its runtime libs from the compiler.

                                  In what way realize ?
                                  It surely uses its runtime files.

                                    when I create a new project there are no these lines.A guy give me a sample project and these lines were in it.
                                    If he dont give me a project .How will I add these line?

                                      Hmm I have looked in Makefile and I encounter this line,
                                      LIBS = -L"$(MINGW)/lib" -static-libgcc --no-export-all-symbols --add-stdcall-alias $(MINGW)/lib/libws2_32.a $(MINGW)/lib/libwinmm.a $(MINGW)/lib/gcc/mingw32/$(MINREL)/libstdc++.a
                                      INCS = -I"$(MINGW)/include" -I"../../../src/sys" -I"../../../src/core" -I"../../../src/lib"

                                      Previously I realised , there is no files in mingw32 5.3.0 but libstdc++ is available
                                      Also existing a this writing in webside, "Libstdc++ are statically linked, so you don’t need to distribute them with your software" I suppose it means that.
                                      I do not have enough knowledge.

                                        Hmm I have looked in Makefile and I encounter this line,
                                        LIBS = -L"$(MINGW)/lib" -static-libgcc --no-export-all-symbols --add-stdcall-alias $(MINGW)/lib/libws2_32.a $(MINGW)/lib/libwinmm.a $(MINGW)/lib/gcc/mingw32/$(MINREL)/libstdc++.a
                                        INCS = -I"$(MINGW)/include" -I"../../../src/sys" -I"../../../src/core" -I"../../../src/lib"

                                        Hi
                                        Statically linked means it is put inside and hence requires no DLL to
                                        be included with the app.
