[dpdk-users] Problems building pktgen

[David Aldrich]

 Hi

I am trying to build DPDK PktGen on Centos 7 using gcc 4.8.5, using the
HEAD revisions of DPDK and pktgen.  The build is failing:

[76/2153] /usr/bin/meson --internal exe --capture lib/ip_frag.sym_chk --
/data/daldrich/pktgen/dpdk/buildtools/check-symbols.sh
/data/daldrich/pktgen/dpdk/lib/librte_ip_frag/version.map
lib/librte_ip_frag.a
FAILED: lib/ip_frag.sym_chk
/usr/bin/meson --internal exe --capture lib/ip_frag.sym_chk --
/data/daldrich/pktgen/dpdk/buildtools/check-symbols.sh
/data/daldrich/pktgen/dpdk/lib/librte_ip_frag/version.map
lib/librte_ip_frag.a
rte_frag_table_del_expired_entries is flagged as experimental
but is not listed in version map
Please add rte_frag_table_del_expired_entries to the version map

Are the "Please add xxxx to the version map" messages errors or just
warnings?

I have put a longer version of this question on StackOverflow, which I
would be grateful if anyone could take a look at:

I answered your post on Stack Overflow, but it is not normally were I look for Pktgen related questions.

The short answer is the errors appear to be from DPDK not having experimental APIs enabled, but I could be wrong.

Let me know if you can not get it working with the step I provided, the problem will be I do not build Pktgen on CentOS.

Thank you for your help, it is building ok now.  Where is the best place to
ask for help with using pktgen?
