S60V5 SDK + GCC 4

[3DGamer]

Hi all,
I've tried to update my s60v5 sdk using this guide, I used the 4.4.1 version as suggested in the comments to the article, however it doesn't work.

When I compile my project (which worked fine with the previous gcc version) the first time after cleaning it, I get one error:

instantiated from here[/S60/devices/S60_5th_Edition_SDK_v1.0/epoc32/include/s32stor.inl]

Here's the part of the commandline output which I think matches:

/S60/devices/S60_5th_Edition_SDK_v1.0/epoc32/include/eikmenup.h:242: warning: enumeral mismatch in conditional expression: 'TFalse' vs 'TTrue'

Now the strange thing: when I build the project again wihout cleaning, It does not report any errors and creates a sis file. This sis file is 30 kb larger than the one built with 3.4.3, and it crashes on the phone (don't know the exact panic, ODD doesn't work).

I really need GCC 4 to use the NEON core of the Cortex-A8, did somebody make it work?

Thanks in advance!

Since it is a warning, your .sis is probably created on the first attempt already. Somewhere it is said that new GCC-s are more strict about the language, that may be a reason for getting new messages.
Upgrading the compiler does not really affect the CPU... Are you testing this code with a device having NEON actually?

Although in the commandline it is called a warning, carbide says its an error in the problems-panel, and it only creates the sis when building the second time.
My test-device is a SE Satio (Cortex-A8).
I need to update to GCC4 to write inline assembly which contains neon-only instructions (doesn't compile on 3.4.3), also the gcc contains the neon intrinsics header ("arm_neon.h") only starting at version 4.

I found out how to make the error and the related warnings go away: add
OPTION GCCE -fno-strict-aliasing
to the mmp file

GCCE now seems to work, basic application created by carbide work fine on my phone, however my project which worked with gcce 3 does not.
