Build WebKit for Qt4.8.7 by GCC13.3
-
Hi,
In buildroot from 2024 with Gcc 13.3 I added the "qt" package to build qt 4.8.7. Everything builds correctly. However, I have a problem after adding QtWebKit. During the build I get an error that doesn't tell me much. Below I am posting the configuration and the error from the terminal. Can anyone direct me on how to compile WebKit?Config:

@Creatorczyk said in Build WebKit for Qt4.8.7 by GCC13.3:
"qt" package to build qt 4.8.7
Why do you want to build this ancient version which is not supported anymore since many years?
-
@jsulm because I am moving an old project written in qt4.8.7 to a new embedded system.
-
@Creatorczyk You may need an old compiler to compile qt4.8.7. GCC13.3 might be too modern for qt4.8.7.
-
@JoeCFD the problem is only when I want to add WebKit. Qt4.8.7 builds without problems
-
@Creatorczyk What is the first error message? What you posted only shows some warnings and notes.
-
Since gcc13 was not yet out when Qt4.8.7 was released some now stricter c++ requirements are in place. you have to fix them by yourself. There error message is clear here - you need a virtual dtor - add it.
