Historically grantlee supported only Qt4 (this version is present now in Buildroot), and for a while both Qt4 and Qt5, and with the last release it dropped the Qt4 support. As for one of my legacy projects i still might need the Qt4 version, i would like to keep the Qt4 support by using the last upstream version which built on Qt4 when Buildroot configured to build Qt4, and use the newest version when build on Qt5. It's easy to implement in the .mk file with "ifeq ($(BR2_PACKAGE_QT),y)", although i'm not sure this is the most elegant solution. (qjson using this for example to distinguish the dependencies between the two Qt version, but it doesn't use 2 different upstream versions for the 2 Qt versions) I got into trouble in the Config.in though. Currently the grantlee.mk selects a few Qt options with the kconfig 'select' statement (namely BR2_PACKAGE_QT_STL, BR2_PACKAGE_QT_SCRIPT, BR2_PACKAGE_QT_GUI_MODULE), and it also supposed to select the corresponding Qt5 options, but i can't find any explicit trace that using conditional 'select' is possible in kconfig, nor the correct syntax to express this. What is the preferred solution to handle this scenario? Would it be better to have a new grantlee package (let's say grantleeqt5) for this latest version, and enable it in the menu only for Qt5? Or is there any kconfig trick i could use here? An other option would be just to drop Qt4 support (if the upstream already did it) at least in the official Buildroot version (and i can use any nasty trick in my own Buildroot tree to support my legacy project till i'm able to port it to Qt5). Is there anybody out there who is using this lib with Qt4? Thanks in advance, regards zgyarmati
