I migrated an *.exe project from Embarcadero C++Builder 10.3 Rio to 12 Athens.
In 32-bit, all works fine, I can compile and link at 32-bit with no problem.
In 64-bit, I can only compile without error, but I get a fatal error in linking:
[ilink64 Error] Fatal: Unable to open file 'VCL.VIRTUALIMAGELIST.O'
Do you have any idea how to fix this?
I have "link with runtime packages" set to true.
When I had a similar problem, I fixed it by making sure that $(BDSLIB)\win64\release is the first entry in the 64 bit library path.
You can do this at Tools | Options | Language | C++ | Paths and Directories or on a project by project basis in the project's settings.
