Windows CE development / VS problems

paul2231

Hi
How do I build for the standard CE 5.0 then ?
Do I need the platform builder, and does that come with VS ?
Thanks.

I have downoaded and installed Windows Mobile 5.0 Pocket PC SDK.msi
checksdk -list now gives a lot more options.

However
when I run nmake I get
cl .....
C:\Program Files (x86)\Windows CE Tools\wce500\Windows Mobile 5.0 Pocket PC SDK\Include\Armv4i\winreg.h(157) : error C2061: syntax error : identifier '__opt'

cl is the correct arm version ?:
cl
Microsoft (R) C/C++ Optimizing Compiler Version 14.00.50725 for ARM
Copyright (C) Microsoft Corporation. All rights reserved.

and for nmake:
nmake -h
Microsoft (R) Program Maintenance Utility Version 8.00.50727.42
Copyright (C) Microsoft Corporation. All rights reserved.

Note: nmake is in a different directory from cl

I have managed to get it to go a bit further, but now I get a missing gmtime function

hey dude! I just created a Wiki page and completely described
"Look at there":http://developer.qt.nokia.com/wiki/Building-Qt-4.7.4-for-WindowsCE-StandardSDK

I've just added a quick note on the bottom of the wiki about the problems with WinCE5 memory limits.

There was an excellent presentation about this at DevDays 2009 but I can't find it any more, do you remember anything about that?

Hi
That final problem was a bug in the souce - I have commented out PNG_CONVERT_tIME_SUPPORTED in pnglibconf.h and it worked fine.

Thanks for sharing your experience!
Actually i've not ever heared about that. Usually i prefer dynamic loading libraries on embedded devices due to memory limits on this sort of devices. Did you have same result on Embedded Linux? One idea is that because the architecture of ARM processors.

I think CE 5.0 only supports 32MB of program+data space (and max 32 processes also). This is fixed in CE 6.0

VS2005 Standard still keeps crashing under Win7-64 bit.
Would it be safe to use VS2010 instead to cross-compile Windows Mobile/CE applications ?
I just thouht I would ask before buying it.

@paul:

I'm not sure if VS2010 can compile for WinCE, it certainly couldn't a year or so ago but it might be okay now.

Is the VS2005 crash happening when you try to compile the Qt libraries from within the tool? I've found that I can only compile QtScript from the command line as it always crashes VS2005 when I load it.

@mohsen:

It's a WinCE5 thing which is a real pain! I haven't heard that any other OS's have this problem.
