[Interest] qt.conf

This does not seem to be explained in the Qt documentation
Reading that implies that the qt.conf can be used to point the application to the location of the qt libraries

I am trying to use the qt.conf functionality
In my qt.conf file I have the following

prefix = "C:\\Program Files (x86)\\AcquisitionSoftware\\Qt<file:///\\AcquisitionSoftware\Qt>"

Running the app through the debugger I can use QLibraryInfo to verify that Qt is recognising the presence of the conf file

QLibraryInfo::location(QLibraryInfo::LibrariesPath) returns C:/Program Files (x86)/AcquisitionSoftware/Qt/lib

However running the application on a machine without Qt installed fails as it cannot locate QCore4.dll

Note that on the target machine the folder C:/Program Files (x86)/AcquisitionSoftware/Qt/lib exists and contains QCore4.dll

That is because your code has not been called yed. The win32 loader cannot find the DLLs needed.

Write a wrapper application that sets parses the .conf file, set PATH correctly and then starts the application. The startup APP must not depend on any DLLs not provided by the OS or have the DLLs on the same dir.

Solution 2:
Move the DLLs to the application directory on windows.

Solution 3:
Does win32 support something like rpath on unix?
