Windows 8.1 : Compile errors from Qt 5.4

[Yorkland]

(VS 2013 community + qt-vs-addin-1.2.3 + Qt 5.4.2) I try to involve the sample code (SimpleVoxelViewer.cpp) into my new create Qt project. I got compile errors while the code involves “PCLViewer” or “CLIManager”, (1) Voxel::PCLViewer v;, or, (2) Voxel::CLIManager manager(sys);

error LNK2019: unresolved external symbol "public: void cdecl Voxel::PCLViewer::stop(void)" (?stop@PCLViewer@Voxel@@QEAAXXZ) referenced in function "public: virtual cdecl Voxel::PCLViewer::~PCLViewer(void)" (??1PCLViewer@Voxel@@UEAA@XZ)

The error message, it looks like I lack some specific lib file(s). But I have involved the following lib(s) in the project setting, What LIB(s) else I need to link? Or that message caused by the other problems?

1. Could you please send all the 4 error messages shown by the linker?
2. Are you using the installed version of Voxel SDK or built it from source?
3. Please share the steps taken to create the Qt project.

I use the installed version of Voxel SDK.

// TI's sample code void VoxelSDKTestByQt1::onActionSimpleVoxelViewer() { Voxel::PCLViewer v; // If disable this line, the errors will disappear. // v.setDepthCamera(depthCamera); // v.start(); // while (v.isRunning()) // std::this_thread::sleep_for(std::chrono::milliseconds(1000)); }

If I enable the line "Voxel::PCLViewer v;", the 4 errors are,

[Error 3] error LNK2019: unresolved external symbol "public: void cdecl Voxel::PCLViewer::stop(void)" (?stop@PCLViewer@Voxel@@QEAAXXZ) referenced in function "public: virtual cdecl Voxel::PCLViewer::~PCLViewer(void)" (??1PCLViewer@Voxel@@UEAA@XZ) [Error 2] error LNK2019: unresolved external symbol "public: bool __cdecl Voxel::PCLViewer::isRunning(void)" (?isRunning@PCLViewer@Voxel@@QEAA_NXZ) referenced in function "public: virtual cdecl Voxel::PCLViewer::~PCLViewer(void)" (??1PCLViewer@Voxel@@UEAA@XZ) [Error 1] error LNK2019: unresolved external symbol "public: cdecl Voxel::PCLViewer::PCLViewer(void)" (??0PCLViewer@Voxel@@QEAA@XZ) referenced in function "protected: void __cdecl VoxelSDKTestByQt1::onActionSimpleVoxelViewer(void)" (?onActionSimpleVoxelViewer@VoxelSDKTestByQt1@@IEAAXXZ) [Error 4] error LNK1120: 3 unresolved externals

While enable the code "Voxel::CLIManager manager(sys); ", I got 2 errors.

Ok. Now I understand.

PCLViewer and CLIManager are not exported classes and used in the app layer alone with no library to link to.

I would recommend you to begin with cpp files from voxel-sdk/Test. Primarily, the CameraSystemTest.cpp to use the SDK layer.

If you need the PCLViewer or CLIManager explicitly for your application, please include PCLViewer.cpp and CLIManager.cpp into your project.

If you want CLIManager in particular, please include LineNoise.cpp and LineNoiseUTF8.cpp as well into your project.

Yes, it's workable. I involve PCLViewer(h,cpp), CLIManager(h,cpp) in the project. Thanks a lot.

[Yorkland]

After involve PCLViewer.h/cpp & CLIManager.h/cpp, I got the new 53 compile errors in "PCLViewer.obj" and "CLIManager.obj".

I list the fist 2 errors, [Error 8] - file: PCLViewer.obj error LNK2019: unresolved external symbol "void cdecl pcl::console::print(enum pcl::console::VERBOSITY_LEVEL,char const *,...)"

[Yorkland]

Sorry, miss your indications, I am trying to involve "LineNoise.cpp" & "LineNoiseUTF8.cpp".

[hlprasu]

As mentioned in a previous message -

If you want CLIManager in particular, please include LineNoise.cpp and LineNoiseUTF8.cpp as well into your project.

Ok, apart from that you'll have to link to PCL and VTK libraries located in PCL install directory.

Linking to necessary PCL and VTK libraries manually might be cumbersome. If you are using CMake for your build system, then have a look at voxel-sdk/App/CMakeLists.txt

An error in "LineNoise.cpp", how to fix the type?

[Error 2] IntelliSense: argument of type "const char " is incompatible with parameter of type "LPCWSTR" [Error 1] error C2664: 'BOOL WriteConsoleOutputCharacterW(HANDLE,LPCWSTR,DWORD,COORD,LPDWORD)' : cannot convert argument 2 from 'const char ' to 'LPCWSTR'

[Yorkland]

I force to change the type by "LPCWSTR()" to solve it temporarily. WriteConsoleOutputCharacter(current->outh, LPCWSTR(buf), len, pos, &n);

There are still 46 LNK2019 errors in "PCLViewer.obj", I think they caused by PCL and VTK libraries, I will try to check the info from CMakeList.txt tomorrow. Thanks for your help anyway.

[hlprasu]

Looks like UNICODE is enabled by default in your code.

Because of this windows API WriteConsoleOutputCharacter(), the second argument type has been changed from LPCTSTR (see https://msdn.microsoft.com/en-us/library/windows/desktop/ms687410%28v=vs.85%29.aspx) to LPCWSTR causing the compiler error.
