link error when using .net and carbide_vs to compile ecom example

[thomasraku]

hi ,

I was trying to compile the ecom example given in the s60 3rd edition sdk( in the path C:\Symbian\9.1\S60_3rd\examples\SysLibs\ECom). I am using the carbide_vs in .net for developing. i import the project using the mmp file .but when i compile it a link error is being shown. the error message is as follows

Error in linking: Object reference not set to an instance of an object.
InterfaceDefinition : error PRJ0003 : Error spawning 'link.exe'.

i tried building it using the command prompt then the error messages are as follows

As of now there is euser.lib in the mmp and i added ecom.lib.
Should i add more lib files in the mmp?
Expecting a solution fro this at the earliest.

Hi,

Carbide.vs does not support 3.0 Final. If you have yourself modified the descriptors to force support, you are on your own.

The update will be out soon.

[thomasraku]

Thank u mitts for the info. i will try with carbide.c++
and see.

I have the same issue with Carbide 2.0.1 that is supposed to support the 3rd edition SDK. command line builds successfully, but Carbide fails:

Hi,

Cannot really tell what is the issue from the the data given. Eg output log from a full rebuild would be help as well as info on how you have created the project etc.

[VigenIssahhanjan]

Make sure that Visual Studio link.exe and supporting libraries are in the PATH environment variable.

Similar experience with the latest Carbide. CodeWarrior 3.1 compile the same plugins without problem. CW not even complain the uid range when the same mmp imported to CW and MS VS C++ (carbide). WC++ is failed to compile it and CW compiles even CW known to be more restrictive. The project is the same therefore I assume the problem is in Carbide.vs. (or in the SDK)

The 3.x port of EcomCalculator and EcomShape example which compile under carbide would be nice to download from Forum Nokia... It can be used as a template and we modify for our purpose. At least a porting document to them under VS C++.

Isn't this simply because Carbide doesn't know what an ECOM plugin is? Change the TARGETTYPE from ECOMIIC to DLL and it should work.

[mitts]

When Carbide.vs imports a TARGETTYPE that is does not support it imports it as if it were a DLL, so changing the TARGETTYPE in the .mmp file to DLL will create consistent build behaviour. However ECOMIIC and DLL have some subtle differences so this might not meet your development needs.

Hi All,

Even I am also facing the same linking error.
I am using carbide.C++ and codewarrior version of SDK.
Any light on this.
If anyone of u have solved it could u please share ur experience here.

Thanks
Chetan

I had this same error when porting an epocexe from 2nd ed to 3rd Ed
The fix was to change the targattype in mmp file from epocexe to exe. - Shame that carbide vs didn't spot the unsupported targettype when loading the mmp file
