When I start my system I get the following error:
WARNING: Error parsing GRE default preferences. Is this an old-style
embedding a
pp?: file d:/xulrunner-9.0.source/mozilla-release/modules/libpref/src/
Preference
s.cpp, line 1063
###!!! ASSERTION: This is not supposed to fail!: 'Error', file d:/
xulrunner-9.0.
source/mozilla-release/js/src/xpconnect/src/nsXPConnect.cpp, line 983
The actual error occurs inside nsXPConnect.FindInfo when the program
invokes
nsIInterfaceInfoSuperManager.HasAdditionalManagers. Evidentally the
result is false and this causes the Assertion to fail in nsXPConnect.
I've built firefox source several times (xulrunner-9.0) but might be
doing something wrong.
I'm not entirely sure what I might be doing wrong, it may be related
to not calling XPCOMGlueStartup.
I stole the code from winEmbed but have problems with it, namely that
XPCOMGlueEnablePreload and/or XPCOMGlueStartup are undefined symbols.
I discovered this is largely because nsXPCOMGlue.h only defines them
if XPCOM_GLUE is defined. However even if I define this flag (the
tutorials I've read say not to) the system is still unable to locate
the functions.
nsresult rv;
//char * path = "D:\\Orpheus\\orpheus\\bin";
// Sophisticated command-line parsing in action
char *szFirstURL = "http://www.mozilla.org/projects/embedding/";;
int argn;
/*for (argn = 1; argn < argc; argn++)
{
szFirstURL = argv[argn];
}*/
strncpy(gFirstURL, szFirstURL, sizeof(gFirstURL) - 1);
ghInstanceApp = GetModuleHandle(NULL);
// Initialize global strings
TCHAR szTitle[MAX_LOADSTRING];
LoadString(ghInstanceApp, IDS_APP_TITLE, szTitle, MAX_LOADSTRING);
MyRegisterClass(ghInstanceApp);
char path[_MAX_PATH];
GetModuleFileName(ghInstanceApp, path, sizeof(path));
char* lastslash = ns_strrpbrk(path, "/\\");
if (!lastslash)
return 7;
strcpy(lastslash, "\\xpcom.dll");
//rv = XPCOMGlueStartup(path);
//if (NS_FAILED(rv))
// return 3;
strcpy(lastslash, "\\xul.dll");
HINSTANCE xulModule = LoadLibraryEx(path, NULL, 0);
if (!xulModule)
return 4;
nsCOMPtr<nsILocalFile> xuldir;
rv = NS_NewNativeLocalFile(nsCString(path), PR_FALSE,
getter_AddRefs(xuldir));
//if (NS_FAILED(rv))
//return 6;
//*lastslash = '\0';
nsCOMPtr<nsILocalFile> appdir;
rv = NS_NewNativeLocalFile(nsCString(path), PR_FALSE,
getter_AddRefs(appdir));
XRE_InitEmbedding2(xuldir, appdir, nsnull);
InitializeWindowCreator();
// Open the initial browser window
OpenWebPage("www.facebook.com");
This is my command for compiling it. I can't get it to find
XPCOMGlueStartup. I'm not sure if this is what causes the Assertion to
fail but I think it likely.
cl -D "XP_WIN" -Zi -I $XULRUNNER_SDK/include -I $XULRUNNER_SDK/
include/mozilla *.cpp $XULRUNNER_SDK/lib/xpcomglue_s.lib
$XULRUNNER_SDK/lib/xpcom.lib $XULRUNNER_SDK/lib/mozalloc.lib
$XULRUNNER_SDK/lib/nspr4.lib $XULRUNNER_SDK/lib/xul.lib user32.lib -
FI "xpcom-config.h"
I'd be grateful for any insight into better approaches in building the
embedding system.
