Converting program from XE2 to 10.2 C++ Builder. Old program used manually installed Abbrevia. Abbrevia 10.3 came with Studio 10.2 and I installed it using defaults. I want to use TCabKit and TMakeCab. Components are in palette.. Placed on a VCL form in a package, not main program. Compiles; functions find the methods they want by pointeers to the compoents. Linker says 'Fatal: Cannpt find AbBase.obj' There IS no such file in the installation. How do I fix this, please.
