<![CDATA[KDChart Library Linking Issue]]>I'm having linking issues to the KDChart library. I've followed the INSTALL.txt. I don't know what I'm doing wrong. I'm using KDChart-2.8.0 and Qt5 on Windows.

Which I found out is used for Visual Studios. I should've been using mingw32-make, because I am using mingw. Thanks for your help. I'll mark as solved.

See https://docs.kdab.com/kdchart/latest/namespace_k_d_gantt.html - this is what linker cannot resolve because you do not link against the lib containing these symbols.

I fixed it and now I'm getting another error that I've not seen before.

Did you use the same compiler for KDChart as you are using for Qt ?
Are you sure the architecture is correct ?

However, I think Qt compiler is 64bit and I'm running mingw32-make to compile the library in the terminal.

What compiler are you using ?
Are you matching 32 vs 64 bit etc ?

Did you compile that DLL yourself ?
