Dolphin Nogui build issue /MemoryWidget.cpp:108:21: error: 'class QComboBox' has no m

[kelv]

Hello

When building Dolphin no-gui for odroid n2+ on linux for EMUELEC and using the latest commits for example (0210d115c22a1c5745c76eaefe38b5d0af3247f9) I'm getting the following error and I can't complete the build. I would like to highlight that with commits from 5c24d7bd8d3ad3f39e2e139b4a41b744fa01b846 and before there are no issues.

Error

/MemoryWidget.cpp:108:21: error: 'class QComboBox' has no member named setPlaceholderText'

Pls can you review the code to fix the issue?. thx

I believe this can be resolved by updating to a newer version of Qt. (Not sure if the bump in required Qt version was intentional or not...)

[GenerationI]

Yes, I can confirm that. Recently I have no longer been able to compile with Qt 5.12 in Linux Mint 20.3.
I needed Qt 5.15 which was not in the repository, so I migrated to Linux Mint 21 which has Qt 5.15 and I could build Dolphin successfully. (The Mint 21 repository also has Qt 6 btw.)
