In IDA I got this behaviour (same for 32bits)

dlopen(/Users/user/.idapro/plugins/ida_palette64.dylib): dlopen(/Users/user/.idapro/plugins/ida_palette64.dylib, 2): Symbol not found: __ZN2QT17QAbstractItemView11eventFilterEPNS_7QObjectEPNS_6QEventE

when I compile it this warning shows up:

[...]
/Library/Developer/CommandLineTools/usr/bin/ranlib: file: palette/libpalette.a(action.cpp.o) has no symbols
[...]

it seems that line could be the issue: https://github.com/Jinmo/ifred/blob/8e9ef6319c019c3985c27098bf04c0c3ac98e468/palette/include/palette/widgets/palette_items.h#L20

Any ideas? Thanks

Hello, it seems like QAbstractItemView is reimplemented in Qt 5.10. Try using a Qt distribution of version 5.6.3 (or 5.6.x; I remember 5.6.12 also worked) from their website: https://download.qt.io/new_archive/qt/5.6/5.6.3/

Oh I see. I'm sorry I tried with 5.6.3 but it looks like I have the similar issue...

Did you manage to compile it on Windows?

Yes. I usually set CMAKE_PREFIX_PATH to contain the path of Qt framework (5.6.3) to ensure that it uses the headers with the right version. If the build refers a wrong version of QAbstractItemView definition, it'll refer this non-existing symbol.

EDIT: I remember using it like -DCMAKE_PREFIX_PATH <QT_INSTALLATION_PATH> e.g. C:\Qt\Qt5.6.3\5.6.3\msvc2015_64. I've added a version check for ida-cmake so it'll raise an error if a wrong version is being used.
