[Solved]Debugging Helpers in Qtcreator don't work on Linux

llCorvinuSll

Hi and sorry for mess English.

In theory while debugging in qt-creator show fields of classes defined in Qt.
But it doesn't do it and display only <not accessible> or mem address.

I think that the problem in GDB or Python scripts.

GDB loaded from http://origin.releases.qt-project.org/gdb/ gives what is described above.

I tried to Build GDB myself with config flags

@configure --prefix=<DIR> --target x86_64-linux-gnu --with-python@

and

@configure --target x86_64-linux-gnu --disable-nls --with-libiconv --with-expat --with-python@

but they crash while starting from Qtcreator

i'm see debugger log from qt creator, and found that GDB return not parsed response like

@{iname="local.ui",name="ui",addr="0xb80170",addr="0xb80170",numchild="0",origaddr="0x7fffffffe578",type="QWidget",value="{...}",}@

on windows i take

@{iname="local.ui",name="ui",addr="0x194b3298",addr="0x194b3298",numchild="5",origaddr="0x28fe28",type="QWidget",value="{...}",}@

differ in numchild, also Q<collection> and QStrings doesn,t show

i'm running on Ubuntu 12.10 x64
Qt version is 4.8.4 (from Git)
and creators are 2.5.2(from qt-project site) and 2.6.81 (git)
GDB versions:
build myself - 7.5
download from qt-project - 7.4.1

on Win8 subject works fine in combination QtCreator(2.6.81)-Qt-4.8.4-MinGW-GDB-7.5(build myself from source with Py. support)

Try to build with http://qt.gitorious.org/qt-creator/qt-creator/trees/master/dist/gdb
it didn't help!

I recently ran into a trap when I did not build Qt with debug symbols: Some datatypes still worked, but others (those using d_ptr) did not.

So do you have debug symbols enabled for the Qt version you are debugging?

SOLUTION: Qt libs didn't contain debug simbols. I was caught by flag -debug-and-release. It work in macOS and windows (MinGW) but not in Linux. Be careful!
