Linker error as Embedded Wizard compiled library sizes have changed for enums and wchars

Question

Hi there,

We use the STM32F769 device, and we've just upgrade from Embedded Wizard Professiona l8.30 -> 14.5. I've managed to get my project to compile with the new libraries:
   STM32F769-Discovery-BuildEnvironment-V14.00.00.00
   STM32-M7-RGB565-SmallBusiness-AddOn-V14.00.00

But the linker stage fails with:

    .\Output\Obj\TOUCH8_APP.axf: Error: L6242E: Cannot link object ewslot.o as its attributes are incompatible with the image attributes.
       ... wchart-16 clashes with wchart-32.
       ... packed-enum clashes with enum_is_int.

The affected files are:
    ewcolor.o, ewdebug.o, ewextbmp_RGB565.o, ewextfnt.o, ewextpxl_RGB565.o, ewextsvg.o,
    ewgfx.o, ewgfxattrtext.o, ewgfxbidi.o, ewgfxcore.o, ewgfxdriver.o, ewgfxsvg.o, ewgfxtasks.o,
    ewobject.o, ewpoint.o, ewrect.o, ewref.o, ewresource.o, ewscalars.o, ewslot.o, ewstring.o, ewtimer.o

My C Compiler is Armcc.exe,V5.06 update 5 (build 528)

I understand the problem is that our compiler is set up for 32 bit wide char, and integer sized enum arrangement.
However, it's clear to me that Embedded Wizard has changed this since 8.30.

Can you explain why this was changed in Embedded Wizard?
Also, what is my way out of this. I'd really like to switch with our current size arrangements if possible.

Kind Regards,
Rob Shand

Hi Rob,

with version 14 we decided to remove the flags

-fshort-enums

-fshort-wchar

from all Keil uVision projects for all platforms. This gives more flexibility for all customer projects. Can you remove these flags from your project?

Best regards,

Manfred.
