QLocalePrivate::longLongToString giving segmentation on Qt 4.8.1

Dcqt

I am trying to run qt examples from Qt 4.8.1 for mips.

compilation no problem. But i am getting segmentaion when running any example.

please help if any one has any idea.

Thanks,

Hi,

Can you try with the latest 4.8 ?

Dcqt

Actually, i cant, because, before compiling for MIPS, i need to apply some patches to qt sources which are not under my control.

I tried adding some prints in the function to find out the problem, but the prints are coming continuously causing segmentation from libc.so instead of libQtCore.so.

Is there any other way i can directly find out why and where it is failing.

Thanks for any help.

Do you mean the patches are out of your control or the sources ?

Dcqt

we got the qt with some board specific patches applied , so i cannot take some other version of Qt and just cross compile.

I hope i am clear, please let me know if its in sufficient.

SGaist

It doesn't mean that they can't be applied also to a later version of Qt.

Anyway, what is the exact error you are getting ?

Dcqt

The error is:
Program received signal SIGSEGV, Segmentation fault.
0x76390efc in ?? () from /usr/local/lib/libQtCore.so.4

Also with a console application ?

Dcqt

not yet, i will give it a try.
but i have a doubt , while compiling Qt i got a warning

Project WARNING: Your mkspec is including 'common/g++.conf', but the mkspecs have been refactored
To fix this include 'common/gcc-base-.conf and 'common/g++-.conf' instead

I guess some thing is missing in the file name the correct name would be g++-<PLATFORM>.conf
( in the make file the value of PLATFORM is not extracted properly i guess )
can i replace g++.conf with g++-unixconf and gcc-base-unix.conf?

any idea , the segmentation coming because of this ?

SGaist

I don't know, but fixing it is a good idea
