"component is built-in" error while installing sis file

[whitewinds]

I'm using series60 3rd version. In my pkg file, I copied a dll file to !:\sys\bin\. But when I installed the sis file on phone, I got "can not install, component is built-in" error, then exit.

I guess that it is because there is already a dll file in the phone with the same name. So I judge the condition in the pkg file like this:
IF NOT (exists("!:\sys\bin\dllname.dll"))
"dllname.dll"-"!:\sys\bin\dllname.dll"
ENDIF

also I tried
IF NOT (exists("dllname.dll"))
"dllname.dll"-"!:\sys\bin\dllname.dll"
ENDIF

But it still gets the same error message.

hi

u got to specify the directory to which u want to sent it c or d drive.

Try this out.

i guess dll's cannnot be loaded again once the phone starts

Thanks.
I am sure there is a same name dll file on the phone. So I want to check whether there is already the dll file in the phone in the pkg file to ensure my app can still work if the dll file is removed from the phone.

I wonder if the exists(filename) can judge a dll file.

You cannot deploy dlls to the phone in the old fashioned S60 2nd edition way. You must install them also as separate applications:

I don't think a DLL with the same _name_ is the problem, that shouldn't matter at all. I believe you might be using a UID that's already used by a built-in DLL or exe.

julian: I haven't had any problems installing DLL:s on 3rd ed devices. I've installed them in \sys\bin, and there's no problem using them.

But I can use other dlls.
Acctually, I copied more than four dll files to the phone in the pkg file like
"\epoc32\RELEASE\armv5\UREL\my.dll"-"!:\sys\bin\my.dll"
other dll files can be installed on the phone except one dll.
This dll file already has been installed on the phone by another application.
That is to say, I have two different applications that use a same dll file.

So when I remove this dll file from the pkg file, I can install the sis file successfully and the application runs well. I am just afraid that another application that has installed this dll may be remove some day and my application can not be used.

How to judge that a dll has been install during pkg install process?

[ptrmn]

Right, of course the installer won't let you overwrite a file that belongs to another app.

I use the exists like this.
IF NOT (exists("!:\sys\bin\dllname.dll"))
"dllname.dll"-"!:\sys\bin\dllname.dll"
ENDIF
But it does not work. if I change the '!' to 'c', it works.
So how can i judge which drive it install in order to judge if the dll is exist.
Or should I write two times for c and e for exists.
