InterfacePointers::Cvar() returns nothing in x86-64-support-sourcesdk

[Be1zebub]

it works well on master, but it returns nullptr on x86-64-support-sourcesdk

reproduce:

#include <GarrysMod/Lua/Interface.h>
#include <GarrysMod/Interfaces.hpp>
#include <GarrysMod/InterfacePointers.hpp>
#include <icvar.h>

GMOD_MODULE_OPEN() {
    ICvar* icvar = InterfacePointers::Cvar();
    if (!icvar) {
        LUA->PushSpecial(GarrysMod::Lua::SPECIAL_GLOB);
        LUA->GetField(-1, "print");
        LUA->PushString("Failed to get ICvar interface!");
        LUA->Call(1, 0);
    	LUA->Pop();
    }
    
    return 0;
}

You need to make a little changes in the ResolveSymbol function:

template<class T>
static inline T *ResolveSymbol(
	SourceSDK::FactoryLoader &loader, const Symbol &symbol
)
{
	if( symbol.type == Symbol::Type::None )
		return nullptr;

#if defined SYSTEM_WINDOWS

	/*auto iface = reinterpret_cast<T **>( symbol_finder.Resolve(
		loader.GetModule( ), symbol.name.c_str( ), symbol.length
	) );
	return iface != nullptr ? *iface : nullptr;*/

	auto iface = reinterpret_cast<T *>( symbol_finder.Resolve(
		loader.GetModule( ), symbol.name.c_str( ), symbol.length
	) );
	return iface != nullptr ? iface : nullptr;

#elif defined SYSTEM_POSIX

	return reinterpret_cast<T *>( symbol_finder.Resolve(
		loader.GetModule( ), symbol.name.c_str( ), symbol.length
	) );

#endif

}

After this changes, the remaining interfaces will be dereferenced correctly for Windows platform.

By the way, the solution to your issue is found in the previous post.

hi, im using linux.
so its not a point.

In that case, you should provide more information about your issue because everything works fine for me when cloning from x86-64-support-sourcesdk repository. Another way, your problem is no longer relevant.
