Cannot compile moongen from github on Centos 8

[rafaelfolco]

This issue is probably a dup of #169
I am opening a new issue since the suggestion on #169 to disable KNI mod doesn't work. Also, I am running centos8.

I was actually able to get to the end of the build after doing two hacks. However, I am looking for ideas on what changes are required for a proper fix in the automated build.
My workaround was to copy the "missing" headers to the build dir:

            cp ./libmoon/deps/dpdk/lib/librte_mempool/rte_mempool.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_net/rte_ether.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_ring/rte_ring.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_net/rte_ip.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_mbuf/rte_mbuf_ptype.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_ether/rte_eth_ctrl.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_kni/rte_kni.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_net/rte_udp.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_ether/rte_dev_info.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_kvargs/rte_kvargs.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_hash/rte_hash.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_ether/rte_tm_driver.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_ether/rte_flow_driver.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_ether/rte_flow.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_ether/rte_tm.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_net/rte_arp.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_net/rte_icmp.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_net/rte_sctp.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/
            cp ./libmoon/deps/dpdk/lib/librte_net/rte_tcp.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/

The 2nd hack was to disable some config settings:

            sed -i -r 's/CONFIG_RTE_EAL_IGB_UIO=y/CONFIG_RTE_EAL_IGB_UIO=n/' libmoon/deps/dpdk/config/common_linuxapp
            sed -i -r 's/CONFIG_RTE_LIBRTE_KNI=y/CONFIG_RTE_LIBRTE_KNI=n/' libmoon/deps/dpdk/config/common_linuxapp
            sed -i -r 's/CONFIG_RTE_LIBRTE_PMD_KNI=y/CONFIG_RTE_LIBRTE_PMD_KNI=n/' libmoon/deps/dpdk/config/common_linuxapp
            sed -i -r 's/CONFIG_RTE_LIBRTE_VHOST=y/CONFIG_RTE_LIBRTE_VHOST=n/' libmoon/deps/dpdk/config/common_linuxapp
            sed -i -r 's/CONFIG_RTE_LIBRTE_VHOST_NUMA=y/CONFIG_RTE_LIBRTE_VHOST_NUMA=n/' libmoon/deps/dpdk/config/common_linuxapp
            sed -i -r 's/CONFIG_RTE_LIBRTE_PMD_VHOST=y/CONFIG_RTE_LIBRTE_PMD_VHOST=n/' libmoon/deps/dpdk/config/common_linuxapp
            sed -i -r 's/CONFIG_RTE_LIBRTE_PMD_TAP=y/CONFIG_RTE_LIBRTE_PMD_TAP=n/' libmoon/deps/dpdk/config/common_linuxapp
            sed -i -r 's/CONFIG_RTE_LIBRTE_AVP_PMD=y/CONFIG_RTE_LIBRTE_AVP_PMD=n/' libmoon/deps/dpdk/config/common_linuxapp

Would you please point me to the Makefile or script to fix this issue ?

Thanks.

@emmericp Would you have any ideas why the .h files from ./libmoon/deps/dpdk/lib are not copied/symlinked to the target build dir at ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/ ?
Thanks in advance

[Rwolkenflitzer]

Thanks for your hacks, helped me with this issue on ubuntu 20.04.

[msherif1234]

Thanks that help me compile on ubuntu 22.04 as well just needed to add

cp ./libmoon/deps/dpdk/lib/librte_kni/rte_kni.h ./libmoon/deps/dpdk/x86_64-native-linuxapp-gcc/include/

but I have linker issues now that need to figure out

@msherif1234 Were you able to fix it? I am running into the same issue.

[g83wang]

@Dhyey-Thummar & @msherif1234

I am also running into the issue. Wondering if we have found a fix for it?

Thank you.

[Dhyey-Thummar]

@g83wang , unfortunately not. The compilation issue still persists. We really wanted to try this, but were not successful. We switched over to using pktGen and trex traffic generator.
