Thanks for your response. I have been using XPCOM for the past month or
so, created a C++ XPCOM component that I am using in javascript within
a XULRunner application. Have not tried using an XPCOM component in a
stand-alone manner from a C++ app before.
I read through the link you sent me and added the following functions
to initialize and un-initialize XPCOM.
bool XPCOMTest::initXPCOM() {
nsresult rv;
nsCOMPtr<nsILocalFile> file;
// rv =
NS_NewLocalFile(NS_LITERAL_STRING("<path_to_firefox>/components"),
PR_FALSE,
// getter_AddRefs(file));
// if (NS_FAILED(rv)) {
// return false;
// }
rv = NS_InitXPCOM2(getter_AddRefs(_serviceManager), nsnull, nsnull);
if (NS_FAILED(rv)) {
printf("Failed to initialized XPCOM2\n");
return false;
}
return true;
}
void XPCOMTest::shutDownXPCOM() {
NS_ShutdownXPCOM(_serviceManager);
}
However the NS_InitXPCOM2 method is always failing. I have tried
passing a nsILocalFile as in the commented out code above the
NS_InitXPCOM2 call, that has also failed.
I am attempting the Standalone Glue strategy, linking to the following
libraries:
-lxpcomglue -lplds4
I was getting link errors without the second library. The original list
of library linkage came from the XPCOM component I created.
Thanks for your help.
