<![CDATA[qtpropertybrowser with Qt6]]>I am trying to compile https://github.com/qtproject/qt-solutions/tree/master/qtpropertybrowser with Qt6. It was originally written for Qt4 but with some changes it also compiles with Qt6.

Unfortunately I get an error from the assembler.

The best solution would be if there is a pure Qt6 PropertyGrid / Browser, but I was not able to find one.

Does anybody have an idea why this happens with Qt6?

Thanks.

it supports both Qt5 / Qt6 at the same time with a very Minimal and stable API while still being very customizable

-Wa,-mbig-obj

(This is ONE compiler flag, so the comma is not a typo!)

Correct. Specifically, it says that the compiler should pass the comma-separated list of arguments that follows (-mbig-obj) to the assembler (-Wa), when it gets run.

There are also -Wp, flags, to pass arguments to the preprocessor stage, and -Wl, flags, when an option needs to go to the linker.

In gcc , at least, the -Xassembler, -Xpreprocessor, and -Xlinker flags can be used to do the same thing one argument at a time, without comma-separating them.

(e.g. these are equivalent:)

$ gcc -Xassembler -mbig-obj ...
$ gcc -Wa,-mbig-obj ...

Use the compiler flag

-Wa,-mbig-obj

(This is ONE compiler flag, so the comma is not a typo!)

I am trying to use the qtpropertybrowser (6.4.3\Src\qttools\src\shared\qtpropertybrowser) in my project.
When compileing qteditorfactory.cpp with

g++ -c -fno-keep-inline-dllexport -g -std=gnu++1z -Wall -Wextra -Wextra -fexceptions -mthreads -DUNICODE -D_UNICODE -DWIN32 -DMINGW_HAS_SECURE_API=1 -DQT_DEPRECATED_WARNINGS -DSETUP_CONFIGURATOR -DNODE_EDITOR_SHARED -DSPDLOG_COMPILED_LIB -DQT_QML_DEBUG -DQT_OPENGLWIDGETS_LIB -DQT_WIDGETS_LIB -DQT_OPENGL_LIB -DQT_GUI_LIB -DQT_SERIALBUS_LIB -DQT_NETWORK_LIB -DQT_SERIALPORT_LIB -DQT_CORE_LIB  -I[...]

  -o debug/qteditorfactory.o ../../../Qt/online/6.4.3/Src/qttools/src/shared/qtpropertybrowser/qteditorfactory.cpp

I get the error

What changes did you make ?
Do you have the same issue with a release build ?

There's a linker flag that you can pass to handle big object but I currently fail to see why you are getting that error.
