Load a dll in symbian

[gacon]

Hi all,

I'm writing an application and some dll file. They were installed on the phone but I cannot launch the application, in fact, it was launched but it was terminated immediately. I think that the problem is the system cannot load the dll file or cannot find the dll file. I tried to put all exe and dll in the same directory in 2 cases: sys/bin/ and create my own folder on c:/myapp/

Does anyone know how to debug this bug?

Thanks,

Assuming an S60 3rd or 5th edition device, \sys\bin is the only place where the OS checks for binary executables (like .dll and .exe).

Thanks for the link, I'm going to read it.

But in the debug mode (i'm using TRK), they cannot be copied to sys/bin, I got permission error.

Starting from S60 3rd edition, everything has to be installed, simple copying does not work (actually you can copy files to \sys\bin of the memory card in USB Mass Storage mode, just those files are going to be rejected by the OS when you attempt to launch them).

Hi,

Your link is talking about debug on emulator, but I'm debuging on phone.

Symbian only load the dll from sys/bin, but in debug mode we cannot copy file to sys/bin. So I don't know how to debug

Try once more, read the "Note!" for example.

You have to add the given .dll files to your .pkg, and install it (if you do not alter its default settings, Carbide.c++ installs your .sisx when you are debugging).

Thanks for your helpful information. Now I'm having some good news, at least I can see the panic code :P.

- I made a debug version and install my application (so all files should be copy to c:\sys\bin\).
- I installed YBrowser and FExplorer but I cannot create a file (I tried to create a new one and copy from outside) ErrRd in c:\resource\. I got a error message, I think that was a permission error.
- I installed Y-Tasks and Panic Observer, now I can see in the log, the panic is "Kill: -1". I don't know what does it mean. I'm trying so search.

Thanks for your help,

Negative numbers are Symbian error codes, http://wiki.forum.nokia.com/index.php/Error_codes
Something is missing. For example your .dll can be such thing (it is still not clear if you install it or what), but data files, images, etc. can be missing too.

Is there any way to know what I'm missing? Because I am not sure which file I'm missing.

Unfortunately no. The logfile of the emulator contains these details, but the device has no such logfile.

What phone model do you use for testing?

Hi,

I'm using Nokia N95, model 8GB black

I guess Lucian's question may continue in a suggestion about making sure that you have actually installed the OpenC/C++ runtime libraries on your device (the .sis files in C:\Symbian\9.2\S60_3rd_FP1\nokia_plugin\openc\s60opencsis and C:\Symbian\9.2\S60_3rd_FP1\nokia_plugin\opencpp\s60opencppsis - you might not need all of them, but PIPS_xy.sis is certainly necessary to do anything OpenC/C++, and STDCPP_xy.sis if you use STL for example).

sorry, but I don't understand what do you mean

You have a thread in the OpenC/C++ boards too (http://discussion.forum.nokia.com/fo...d.php?t=200976), is this thread+question related to that one?
