.exe: section .data loaded at [00400000,00400003] overlaps section .ARM.extab loaded

[vishalrocks101]

Hi,

When I device build my app I am getting following problem:

c:/qtsdk/symbian/tools/gcce4/bin/../lib/gcc/arm-none-symbianelf/4.4.1/../../../../arm-none-symbianelf/bin/ld.exe: section .data loaded at [00400000,00400003] overlaps section .ARM.extab loaded at [003fafcc,0040630f]
   c:/qtsdk/symbian/tools/gcce4/bin/../lib/gcc/arm-none-symbianelf/4.4.1/../../../../arm-none-symbianelf/bin/ld.exe: C:/QtSDK/Symbian/SDKs/Symbian3Qt472/epoc32/release/armv5/udeb/Mixologist.exe.sym: section .data vma 0x400000 overlaps previous sections
   c:/qtsdk/symbian/tools/gcce4/bin/../lib/gcc/arm-none-symbianelf/4.4.1/../../../../arm-none-symbianelf/bin/ld.exe: C:/QtSDK/Symbian/SDKs/Symbian3Qt472/epoc32/release/armv5/udeb/Mixologist.exe.sym: section .bss vma 0x400004 overlaps previous sections

Can any one tell me what is the problem

I am using qt4.7.2

Thanks with Regards,

let if know if adding

QMAKE_LFLAGS.GCCE += -Tdata 0x700000

this to your .pro file help.

also note that you have to delete the mmp file generated manually before you build with new changes in pro file for device build.

HI,

After putting it problem still appears. I have deleted mmp file, then also .

And IN mmp it is getting reflected:

OPTION CW -cwd include -wchar_t on
OPTION ARMCC --visibility_inlines_hidden --fpmode fast
#if defined(ARMCC_4_0)
OPTION ARMCC --import_all_vtbl
#endif
OPTION GCCE -fvisibility-inlines-hidden
LINKEROPTION GCCE -Tdata 0x700000

[skumar_rao]

can you let me know which code you are trying to build ?

[danhicksbyron]

This happens when the code and data sections collide because the app is so large. The fix is to place the following in your pro:

QMAKE_LFLAGS.ARMCC += --rw-base 0x700000
QMAKE_LFLAGS.GCCE += -Tdata 0x700000

The 0x700000 value in your case could probably be dialed down to 0x500000.

HI,

I had tried it but no effect then I found this link http://bugreports.qt.nokia.com/browse/QTBUG-17345
I think it is unresolved bug.

Hi skumar_rao,

Actually it is a huge project , and I think that's why this problem is occuring.

last time i got this error while port Apache Thrift to Qt but that was using 4.6.2 #2 fixed that problem. Do you have something similar in your code.

also try reducing the files in your application to find which module is giving your the error.

[danhicksbyron]

Well, works fine with the old kit.

[danhicksbyron]

You can try removing stuff from QRC files and see if that helps. (Large files should not be put in QRC files anyway.)

Hi all,

Finally Good news I dont know how When I build my app on release mode it built successfully.. kind of magic to me,, dont know how and running fine on device....

Thanks with Regards,
Vishal

[danhicksbyron]

Release mode would produce somewhat smaller object files. You were just on the hairy edge, size wise, to begin with, so recompiling in release mode would easily put you under the limit.

I faced same problem in my project because my app is too large, this problem is resolved when i build my application on release mode.
