GCCE compile warnings using S60 3rd ed SDK

[RyanSantos]

I am currently trying to install GCCE compiled binaries to a Nokia device. However, after creating a sisx file, the Nokia device rejects the sisx file with a "File Corrupted" error message. I do not encounter any warnings when invoking the compiling fromt the command line except that the version of the RCVT compiler cannot be determined. The *.exe file gets produced anyway. Trying to compile in CodeWarrior using GCCE with the ff Symbian Compiler settings

Compiler: ARM GCCE

Prefix File: gcce.h

Macros:
__SYMBIAN32__,__SERIES60_30__,__SERIES60_3X__,__GCCE__,__EPOC32__,__MARM__,__EABI__,__MARM_ARMV5__,__EXE__,NDEBUG,_UNICODE,__GCCE__,__SUPPORT_CPP_EXCEPTIONS__,__PRODUCT_INCLUDE__

Arguments:
-march=armv5t -mthumb-interwork -mapcs -msoft-float -fexceptions -pipe -nostdinc -Wall -Wno-ctor-dtor-privacy -Wno-unknown-pragmas

result in the ff warnings:
1. _FOFF of e32def.h
- 2 warnings occur whenever this is used
a. the compiler complains "invalid access to non-static member" regarding the 2nd parameter of _FOFF
b. "perhaps the 'offsetof' macro was used incorrectly" warning

2. "Enumeral mismatch in conditional expression: 'TFalse' vs 'TTrue'" in eikmenup.h line 183

inline TBool CEikMenuPaneItem::IsScaleableText(const TDesC& aText) const
{
return (aText.Locate(TChar(KScaleableTextSeparator)) == KErrNotFound ? EFalse : ETrue);
}

Changing the return line to

return !(aText.Locate(TChar(KScaleableTextSeparator)) == KErrNotFound);

removes the 2nd type warning.

Aside from these warnings I do not see any errors and hope that I have not missed any other warnings that might cause the corrupting of the SISX file.

Hello Ryan.

I came across this thread because I have the same issue with GCCE. (SDK 3 Beta). You say you compiled it for a platfrom? Can u please say what kind of device u are using for testing this on? As far as I know there is a total binary brake from Symbian OS 9 onwards. Could this be the reason?

Your following code is advised against by the Symbian experts:

inline TBool CEikMenuPaneItem::IsScaleableText(const TDesC& aText) const
{
return (aText.Locate(TChar(KScaleableTextSeparator)) == KErrNotFound ? EFalse : ETrue);
}

becuase u should not check your return results as follow:

TBool Ret = SomeFunction();
if ( Ret == ETrue )
{
...
}

but rather like this

TBool Ret = SomeFunction();
if ( Ret )
{
...
}

.i.e. any positive value should be true. So the following is slightly more effecient

return !(aText.Locate(TChar(KScaleableTextSeparator)) == KErrNotFound);

I guess.

Best,
Johan.

inline TBool CEikMenuPaneItem::IsScaleableText(const TDesC& aText) const
{
return (aText.Locate(TChar(KScaleableTextSeparator)) == KErrNotFound ? EFalse : ETrue);
}

The code above is not my code but is inside one of the S60 3rd ed system headers.

Ryan,

Did you find a solution to the corrupted files made by gcce? I am having the same problems and need the same solution.

I was not able to make the app work before returning the device to Nokia. From one of the posts here it was suggested that I should use an app uid from the range 0xE0000000 - 0xEFFFFFFF. Your app will not work with the emulator though when using this UID. Just revert back to your orig UID when working with the emulator.

Check https://www.symbiansigned.com/app/page/uidfaq then please post if this solution solves your problem. This was what I was planning to do the next time that we borrow a device from Nokia.
