Subject: [dpdk-dev] g++: undefined reference to
Date: Thu, 2 Jan 2014 13:05:00 +0330 [thread overview]
Message-ID: <CACu58pBirLHpm51RCXWbsQZF=NVGtCYkc-+e9ffUQLxpOgxNeQ@mail.gmail.com> (raw)
Hi,
I wanted to write a simple program using class (object oriented). I've
attached my helloClass.cpp and also Makefile. after runnig make I get
below errors.
I think:
1. it is the problem of using c code in c++
2. I've used extern "C" in helloClass.cpp
3. Should I recompile the DPDK from source with gcc -c argument for
compatibility with g++?
Thanks in advance.
g++ -c helloClass.cpp
-I/home/hamid/dpdk/dpdk-1.5.1r1/x86_64-default-linuxapp-gcc/include
g++ helloClass.o
-I/home/hamid/dpdk/dpdk-1.5.1r1/x86_64-default-linuxapp-gcc/include
