issue regarding UDP-socket demo about dpdk-ans HOT 6 CLOSED

Maybe it related to txq_flags:0xfffff1ff.
You may set txconf->txq_flags = 0;
or you try the latest dpdk-ans.

Thank you for the reply !!

It says that the latest dpdk-ans is compatible with:
Development environment is based on x86_64-native-linuxapp-gcc;
Linux version： 4.4.0-45-generic (Ubuntu 16.04.1 LTS).
GCC version： gcc version 5.4.0 20160609.

But I have Linux version: 3.13.0-32-generic (ubuntu 14.04). Will the latest version of dpdk-ans work fine with my configuration?

from dpdk-ans.

And with the latest version, when I run install_deps it asks me to generate librte_ans.a/librte_anssock.a separately.

./install_deps.sh

Start to generate librte_ans.a/librte_anssock.a for -mnative.
Your native march is corei7-avx.
Your native march is none of westmere/sandybridge/ivybridge/haswell/broadwell.
You may generate librte_ans.a/librte_anssock.a based on your -mnative by manual,
Or ask help from ANS develop team.

maybe it support 3.13.0-32-generic (ubuntu 14.04), but you could update your gcc to 5.4.0. the march name(corei7-avx) cloud change to another name

from dpdk-ans.

I did update my gcc version to 5.4.0, gcc (Ubuntu 5.4.1-2ubuntu1~14.04) 5.4.1 20160904
But the latest version of ans (17.08) is giving error while compilation,
dpdk-ans-ans-17.08/ans# make
LD ans
/usr/bin/ld: /root/dpdk_latest/dpdk-ans-ans-17.08/librte_ans/librte_ans.a(ans_init.o): unrecognized relocation (0x2a) in section `.text'
/usr/bin/ld: final link failed: Bad value
collect2: error: ld returned 1 exit status
make[1]: *** [ans] Error 1
make: *** [all] Error 2

This was not the case when I was compiling with older versions of dpdk-ans. Is it because of compatibility with 14.04 version of ubuntu ?? or this seems to be some different issue.

from dpdk-ans.

shall upgrade binutils.
