Hi all,

I am using Visual C++ 2005 to create an XPCOM component. I am facing
the following error.

error LNK2001: unresolved external symbol "__declspec(dllimport)
public: int __thiscall nsOutputStream::write(void const
*,int)" (__imp_?write@nsOutputStream@@QAEHPBXH@Z)

I believe that the error occurs when it run the following code:

char *s = PR_smprintf("xxxx");
PRInt32 L;
L = strlen(s);
//mStream is a variable of nsOutputFileStream.
if (PRInt32(mStream->write(s,L)) < L) {
return NS_ERROR_FAILURE;
}

Does any one know what is the problem with this error. Thanks in
advance.

Regards
LKY

This is really a build problem.

Looks like a linking problem... With which libraries are you linking?

Hi,

Thanks for reply. I am using Gecko SDK 1.8. Is this the libraries that
you mean?

Which linkage are you using

Hi,

Thanks for reply. I am using Frozen linkage (dependent glue). For
Windows one.
