We've found that adding a TAdvRichEditor component to a RAD Studio 11.2 C++ project results in the following linker errors (without linking with dynamic packages/rtl),
Unable to open file 'GDIPlus.lib'
Unable to open file 'WININET.lib'
Unable to open file 'URLMON.lib'
To resolve this, we've copied the .a files to .lib to workaround. For some reason this component is looking for .lib files instead of .a files in 64-bit. We've found the same in other components and have done a similar workaround.
