[Gdal-dev] 1: HELP: GDAL for windows CE

Mon May 8 06:09:27 EDT 2006

Hello Mateus,

Hope you had a good short holiday.

Have you had time to look at my email below? I could not get the STL, you mention in the Readme, to compile for the Emulator. Is that why I cant get the ogr source files to compile for the Emulator?

Regards,
Vasku

Hi there Mateus,

Finally I got the source files to compile.

I changed 
port/cpl_config.h.evc4
to read:
port/cpl_config.h

This still did not solve the problem. I had to add ex to your #define in  cpl_config.h

So for example:
#define strerror wce_strerror /* defined in cpl_wince.h */

was changed to read

#define strerror wceex_strerror /* defined in cpl_wince.h */ (extra ex in wce_strerror)

I had to do this through out the cpl_config.h file. Where ever I found wce I added ex to it.

After these changes I managed to get the source to compile but there were 51 warnings all to do with the same file cpl_string.h: The warning is -

c:\gdal-131a_wince\gdal-cvs-2006.04.26\port\cpl_string.h(211) : warning C4275: non dll-interface class 'std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' used as base for dll-interface class 'CPLString'

Is it ok if I use the DLL as is?

I managed to compile the source for the device but could not get it to compile for the emulator. I need to get it to work as I will be testing my code first using the emulator.

When I try to comiple for the emulator I get the following error 14 times relating to different files:

C:\Gdal-131a_wince\gdal-cvs-2006.04.26\port\cpl_conv.cpp(1495) : error C2373: 'CPLFreeConfig' : redefinition; different type modifiers
        C:\Gdal-131a_wince\gdal-cvs-2006.04.26\port\cpl_conv.h(157) : see declaration of 'CPLFreeConfig'

I find it strange. The header file has a different function declaration for CPLFreeConfig than what is used in the .ccp file.

Why can I not compile for the emulator?

Regards,
Vasku

PS: In your last email you stated

Look in the following directory ogr\ogrsf_frmts\dgn\dist. You should find another copy of cpl_config.h

I am glad it works now.

Yes, it's possible. Let's start to solve those problems :-)

I assume you've fulfilled those software requirements.

Yes, it's possible.

Yes, it should fix the problem. But I'd prefer to use notepad, instead
wordpad.

Ups! It seems you've found it's missing in the README.
I've forgot to explain this step.

if you're using eVC++ project files, you have to rename file:

port/cpl_config.h.evc4

to read:

port/cpl_config.h

Hmm, I don't have this file there in the ogr subdir.
cpl_config.h should be renamed as I'm explaining above

That's the problem. I mean, you need to have cpl_config.h renamed as
said above.
You can look into the port/cpl_config.h.evc4 file and you will see
dedicated #if's for errno.

Please, follow my guidelines above related to cpl_config.h and it should
work. Simply, I've forgot to add appropriate instructions to the
wince/README file.

I'll fix it soon when I'm back home after Friday (I'm on small holidays).

What's the problem here?
What is the error message?

Please, first try to build using eVC++ project files with my
instructions how to get cpl_config.h files.
