Install Fails on Arch

I get this when trying to install ksmoothdock from the aur: /home/frostranger/.cache/yay/ksmoothdock/src/ksmoothdock-6.2/src/model/application_menu_config.cc: In member function ‘bool ksmoothdock::ApplicationMenuConfig::loadEntry(const QString&)’:

Using the git version also fails with the same error

Thanks for reporting.

Yeah they are deprecated in Qt 5.15 which was released last month. You have a very up-to-date system.

I'll fix it.

In the mean time, can you try to remove these 2 lines from src/CMakeList.txt:
add_compile_options(-Wall -Werror)
add_definitions(-DQT_DEPRECATED_WARNINGS)
and build again?

Basically, currently all warnings are treated as errors.

Same problem with KDE Neon which has too the 5.15 version of Qt
Removing the 2 lines in CMakeList.txt solve the problem of compilation

Fixed in v6.3
