error: lvalue required as unary '&' operand

int CComponentPool::RemoveComponent(char *id)
{
	vector<CMTComponent *>::iterator ci;

	for ( ci = m_Components.begin() ; ci != m_Components.end() ; ci++ )
	{
		if ((*ci)->m_ID == id)
		{
            (*ci)->Stop();
            m_MapComponents.erase(((CMTComponent *)(*ci))->m_Type);
            FreeComponent *hFreeComp = (FreeComponent *)COsLibrary::GetProcAddr(m_MapComponents[((CMTComponent *)(*ci))->m_Type], FCFN);
            hFreeComp(&((CMTComponent *)(*ci)));
            m_Components.erase(ci);
			
			break;
		}
	}
	return 0;
}

相关的的定义如下，

#ifdef WIN32
extern "C" __declspec(dllexport)  void FreeComponent(CMTComponent** pComponent) 
#elif defined(LINUX)
extern "C" void FreeComponent(CMTComponent** pComponent)
#endif
{
    SAFE_DELETE( *pComponent);
}

FuncAddr COsLibrary::GetProcAddr(LibHandle hModule, char *lpProcName)
{
    return dlsym(hModule, lpProcName);
}

std::map <int, LibHandle> m_MapComponents;

这个程序在VC2010下编译没有问题，在LINUX下用gcc编译，在 hFreeComp(&((CMTComponent *)(*ci))); 处编译报错 error: lvalue required as unary '&' operand

FreeComponent(CMTComponent** pComponent)是个库导出函数， 在int CComponentPool::RemoveComponent(char *id)这个文件的头文件里有 typedef void FreeComponent(CMTComponent **);
