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 -lstdc++ helloClass.o: In function `rte_lcore_id': helloClass.cpp:(.text+0x7): undefined reference to `per_lcore__lcore_id' helloClass.o: In function `rte_get_master_lcore': helloClass.cpp:(.text+0x15): undefined reference to `rte_eal_get_configuration' helloClass.o: In function `rte_lcore_is_enabled': helloClass.cpp:(.text+0x2a): undefined reference to `rte_eal_get_configuration' helloClass.o: In function `HelloClass::HelloClass(int, char**)': helloClass.cpp:(.text._ZN10HelloClassC2EiPPc[_ZN10HelloClassC5EiPPc]+0x20): undefined reference to `rte_eal_init' helloClass.cpp:(.text._ZN10HelloClassC2EiPPc[_ZN10HelloClassC5EiPPc]+0x4b): undefined reference to `__rte_panic' helloClass.o: In function `HelloClass::run()': helloClass.cpp:(.text._ZN10HelloClass3runEv[HelloClass::run()]+0x3f): undefined reference to `rte_eal_remote_launch' helloClass.cpp:(.text._ZN10HelloClass3runEv[HelloClass::run()]+0x80): undefined reference to `rte_eal_mp_wait_lcore' collect2: ld returned 1 exit status make: *** [helloClass.o] Error 1 All the Best, Hamid
