The strings in both QtCore and qmake come from src/corelib/global/qconfig.cpp, which have a telling prefix. You should match them when followed by the prefix you configured. Those strings are always 256+12 bytes in length, which should work for *most* (not all!) paths, and also allow you to install to a path longer than your original prefix. The mkspecs files are text, so just do a regular text replace. There may be some other places where the prefix is hardcoded by the toolchain itself and those usually do not reserve space. For example, on ELF systems, there maybe DT_RPATH / DT_RUNPATH headers (you can use chrpath to change them, or binary-edit directly). The path may also be present on the debug symbols and, worse, it might be compressed. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
