C++ class declaration and include issues in gsoap

I compile a file in a gsoap project with the following command.
Almost all files in my project are generated by the gsoap tools and i am new to C++ so i cant tell very much about it.

All in all i need to understand if my project could compile at all. Do i need other flags?

gcc -c  -I/usr/include/gsoap soapAuftraegeImportSoap11BindingProxy.cpp

the current error is:

soapAuftraegeImportSoap11BindingProxy.cpp:10: error: 'AuftraegeImportSoap11BindingProxy' has not been declared

this line 10 is:

AuftraegeImportSoap11BindingProxy::AuftraegeImportSoap11BindingProxy()

the file starts with this include:

#include "soapAuftraegeImportSoap11BindingProxy.h"

but in the header file there is no declaration of the class. And nowhere else. See also further errors:

soapAuftraegeImportSoap11BindingProxy.cpp:10: error: 'AuftraegeImportSoap11BindingProxy' has not been declared soapAuftraegeImportSoap11BindingProxy.cpp:10: error: ISO C++ forbids declaration of 'AuftraegeImportSoap11BindingProxy' with no type soapAuftraegeImportSoap11BindingProxy.cpp: In function 'int AuftraegeImportSoap11BindingProxy()': soapAuftraegeImportSoap11BindingProxy.cpp:11: error: 'AuftraegeImportSoap11BindingProxy_init' was not declared in this scope soapAuftraegeImportSoap11BindingProxy.cpp: At global scope: soapAuftraegeImportSoap11BindingProxy.cpp:14: error: 'AuftraegeImportSoap11BindingProxy' is not a class or namespace

Hopefully my question makes sense to you.

just to close this issue , i post my makefile

C=g++
CCPLUS=g++
CFLAGS=-c  #-Wall
