Symbian GUI application and OpenC

[igor_k11]

Hi all

I need help in such question - is it ever possible to use OpenC in the standard Symbian GUI application (S60 3rd edition)?
I mean to use stl and boost in the application, which is based on standard GUI framework(E32Main looks like this
TInt E32Main()
{
return EikStart::RunApplication(NewApplication));
}
I have very strange behaviour during debigging such project - debugger runs into some functions which I don't call at all, aplication crashes in some places which did not crash before using OpenC etc.
I have read Getting started with Open C and Getting started with The Standard C++ Library articles, set all settings but it did not help
Is it possible to use OpenC in that way?
What can be a reason of such behaviour?
(One more note - I link static library also written with help of Openc to my application)

Will be thankful for any help - that strabge problems make me crazy

It is certainly possible.

I would first check that you have "LIBRARY libc.lib" in your MMP file so the linker doesn't accidentally and implicitly link to incompatible compiler runtime support libraries for standard C library functionality.

Thank you for answer

Yes, my mmp file contains reference to libc.lib library, so it cannot be a reason of problem

Ok, please post your mmp file anyway - it's a good starting point for investigation.

Ok
It is my mmp file
Actually it is based on the one of examples from this forum

Hi,

I've created a hybrid application like you're suggesting without any problems.

What are you testing on? S60 3rd MR emulator? Real device (which one)? Some later SDK?

Have you got the latest version of Open C/C++ installed? Did you have a previous Open C installation before using Open C++?

Ebra is correct that you shouldn't have libcrt0.lib linked in if you are running from E32Main() (which you will be for a Symbian GUI application). However, that shouldn't be causing the only problem because I think having eexe.lib linked before it in the MMP will cause the correct symbol to get picked up first.

The problems you are describing sound very much like you have some incompatible libraries linked in, which is why I'm asking about what versions you are using.
