Error on 'qdbusmessage.h' when building under Ubuntu 20.04

[Nuk]

I tried several times with 'master' branch and 'v1.1' tag, but failed to build under my Ubuntu machine,

Errors occurred :

How can I fix this ?

• My build environment:

• OS : Ubuntu 20.04.5 LTS (kernel 5.15.0-67)
• CMake version: 3.24.4

Thanks,

Hi,

This unfortunately is an issue with the version of the Qt library that we're currently using. The fix for it is to go into the `..../JARVIS-AcquisitionTool/libs/Qt/qt_install/include/QtDBus/qdbusmessage.h' file and change:

#if defined(Q_OS_WIN) && defined(interface)
#  undef interface
#endif

to

#  undef interface

I'm not sure what exactly the cause for this issue is, but this fix works for me.
I hope this helps and please let me know if you have any other issues!
