[Kwiver-users] Map-TK Linker Errors on Windows

[Matthew Leotta]

Kyle,

I don’t know what the issues is off hand.  For the v0.7.x installers we focused on making sure the executables and GUI could be installed and run.  While the package does included header file and and libraries, we didn’t test its use as an SDK.  I suspect there is something not configured correctly in the installed package.  If you want to develop code against MAP-Tk, you may have better luck if you build from source.

I don’t have time to look at this issue with the installer anytime soon.  I’m preparing for the upcoming v0.8.0 release.  If this issue persists with the v0.8.0 release then we will probably address it there.  However, we are moving to C++11 with MAP-Tk v0.8.0, which means dropping support for Visual Studio 2010.  So that may be an issue for you.  We are continuing to support Visual Studio 2013 and above.

—Matt
