Linking issues on Visual Studio 2019

Bug Report

Please answer the following questions for yourself before reporting a bug.

• [ X ] I checked the documentation and the forum but found no answer.
• [ X ] I checked to make sure that this issue has not already been filed.

Environment

Select the following information.

• DART version: [e.g., master, 6.8.3]
  -- 6.9.2
• OS name and version name(or number): [e.g., Ubuntu 18.04, macOS Mojav, Windows 10]
  -- Windows 10
• Compiler name and version number: [e.g., GCC 7.4.0, Clang 3.9.1]
  -- Visual Studio 2019 (MSVC 142)

Expected Behavior

Please describe the behavior you are expecting.

Compile the hello-world example, after successfully installed DART on Windows following the guide.

Current Behavior

What is the current behavior?
If you have trouble in cmake or make, it would be very helpful to build DART with verbose option:
$ cmake .. -DDART_VERBOSE=On
$ make VERBOSE=1
and then dump the results into a gist and share the link to gist here.

Before this Issue:

I met some other issues to compile the VS solution that CMake generates for the DART examples.

• The installation of DART is swift and fluent.
  • Boost version is 1.72.0, caused some warnings.
  • OSG version is 3.6.4, and is built from source previously.
• Template issue that cannot compile, as described in this issue (Build on Windows with Visual Studio 2017 (Clang toolchain) #753). It is resolved after adding the /permissive- flag.
• Some other MACRO issues. Resolved by adding the definition of _USE_MATH_DEFINES . (as this post tells)
• Linking errors because some libraries were not added by CMake. In my case assimp, fcl and osgUtil are not in the Input field of linker property.

Linker Issue:

After resolved all the issues above, there are still 7 unresolved externals, which caused LNK1120 error.

The unresolved external symbols are:

__declspec(dllimport) public: __cdecl dart::gui::osg::TrackballManipulator::TrackballManipulator(int)" (__imp_??0TrackballManipulator@osg@gui@dart@@QEAA@H@Z)

A more complete error information for the first of it is as follows: (dart-gui-osg.lib(Viewer.obj) might be informative)

Severity	Code	Description	Project	File	Line	Suppression State
Error	LNK2001	unresolved external symbol "__declspec(dllimport) public: __cdecl dart::gui::osg::TrackballManipulator::TrackballManipulator(int)" (__imp_??0TrackballManipulator@osg@gui@dart@@QEAA@H@Z)	hello_world	C:\dev\dart-6.9.2\examples\build\hello_world\dart-gui-osg.lib(Viewer.obj)	1	

All are related to dart::gui::osg::TrackballManipulator and this is strange. I have used dumpbin to check the symbols, and in all of the dart library files, there are related symbols in dart-gui-osg.lib (the RelWithDebInfo version, but I compile with Release version), and it contains related symbols, as follows:

P.S. I also tried with the config RelWithDebInfo, the same.

Thank you for your help. And maybe I would better try to develop under Linux. I can get everything works on Linux but I have to remotely use it because of the pandemic. Everyone, keep safe.

[Tomohiro-Nagasaka]

When building libraries and hello-world, I added OSG_LIBRARY_STATIC to preprocessor macro. I could build but there still is an error on runtime reported here: #1431

I believe this issue is fixed by recent build fixes for Windows. Please reopen if that's not the case.
