Same code, missing qtintf70.dll

Compiling some old code, my application will no longer run. Newly compiled exe-file won't start "because qtintf70.dll is missing from your computer".

Strange thing: an older exe file compiled from exact same code runs just fine. Both exe files tested on same system, but compiled on different Delphi installations (both Delphi 7 running on VirtualBox).

Googling, someone suggested "You have pulled in Clx somehow. Clx apps require the QT library. Look for units in your uses clauses that start with Q." but again: this is the exact same code. I've checked and can't find anything.

Suggestions?

Solution

  • In D7, the only source code units which reference qtintf70.dll are QForms.Pas and Qt.Pas.

    So, what you need to do is to

    1. Move all instances of these two files and their corresponding .DCU files to somewhere not on your project's search paths. Use a utility like SwiftSearch to make sure you find all of them.

    2. Do a full build of the project.

    The build should grind to a halt somewhere with a complaint that the compiler can't find one or other of these units. The source unit that is being compiled at the time is the one which contains a reference to one or other of them.
