    In my QT 5.1 source, there is no file udat.h.

    The file /qt-everywhere-opensource-src-5.1.0/qtwebkit/Source/JavaScriptCore/runtime/DatePrototype.cpp includes it.

    I'm happy to change the include path to point to it, but I can't seem to locate it...

    Where is udat.h?

      Hi and welcome to devnet,

      ICU is a dependency you have to install before compiling Qt.

      Otherwise if you don't use WebKit you can also avoid building it

        Hi, thanks.

        Ok, but there's an icu folder in that directory. Shouldn't it have what I need? I modified the makefiles for several of the other folders to include ./icu/, and that seems to of gotten them over the hump.

          If I'm not mistaken, this folder contains only headers so nothing to link against

            Ah, right. I do have libicu-dev installed, but hadn't thought to point QT to my system /usr/include directory. I'll add it to the end of the list. Thanks.

              On another note, if these files are required in the system, shouldn't QT look there by default?

                ICU is not required, unless you want to build QtWebKit

                  Ok, but in the make files for QtWebKit, it should point to the systems /usr/include directory, no?

                    I haven't checked recently but I'm not sure that ICU is installed by default on linux

                      That's not really the issue here. Even if I do have them installed, the make file will never find them, unless I go and edit it. It's not a good idea to make people edit make files in order to install the framework. If it is installed, it will probably be in /usr/include. The make files should point there by default.

                        Are you sure you have ICU's headers installed ? Installing the library doesn't mean that the headers are also there. Generally they are part of the corresponding dev-package

                          I'm sure. As I mentioned earlier, libicu-dev is installed.

                            I think you're still missing the point. How in the world does the make file know if I have ICU installed or not? It doesn't even try to look into /usr/include.

                              The makefile doesn't. It's the configure scripts that searches for installed elements to do the automatic enabling/disabling of features.

                                Well, really the configure script uses my qconf file to tell the make files where to look. But yes, it happens when you execute the configuration. I will add /usr/include.
