Linking with XulRunner v.34 to create an XPCOM extension for Firefox

Question

I am using the latest Gecko SDK (xulrunner-34.0.5.en-US.win32.sdk) with MSVS 2013 and I am facing serious issues with the linker (and apparently I am not the only one).

After a lot of workarounds for various issues I get these linker errors:

            Error   3   error LNK2001: unresolved external symbol "enum tag_nsresult __cdecl NS_TableDrivenQI(void *,struct nsID const &,void * *,struct QITableEntry const *)" (?NS_TableDrivenQI@@YA?AW4tag_nsresult@@PAXABUnsID@@PAPAXPBUQITableEntry@@@Z)   C:\Users\user\Desktop\sample\sample\sample\nsSample.obj sample

I have added ALL the LIB files from the SDK and still nothing. I have found similar problems from other developers, but no solutions:

https://bugzilla.mozilla.org/show_bug.cgi?id=682259

The last link is supposed to provide a solution, but it is not working for me (and for another user at that page).

Has anyone any hints/solutions/suggestions for this issue?

UPDATE:

After defining XP_WIN, I get only one linker error:

LNK2001: unresolved external symbol "public: unsigned short const * __thiscall nsAString::BeginReading(void)const " (?BeginReading@nsAString@@QBEPBGXZ) C:\Users\user\Desktop\sample\sample\sample\nsSample.obj sample

That seems to bring me at the same place as this guy:

UPDATE2:

This had to do with a previous problem that I had with conflicting typedefs for char16_t inside mozilla's Char16.h and MS's yvals.h:

typedef wchar_t char16_t;
vs
typedef unsigned short char16_t;

My new solution was to define the _CHAR16T to prevent MS headers typedef-ing char16_t.

Answer 1

OK. The problems were:

1. I had to define XP_WIN.
2. I had to define _CHAR16T to prevent MS headers typedef-ing char16_t.

These are the libs that I have as dependencies on at the moment:

crmf.lib
nss3.lib
unicharutil_external_s.lib
mozjs.lib
xpcomglue.lib
xpcomglue_staticruntime.lib
xpcomglue_staticruntime_s.lib
xpcomglue_s.lib
mozglue.lib
mozalloc.lib
