I am using DPDK 21.11.2 as packaged on Ubuntu 22.04 LTS.
I have a very simple program that initialize the EAL and then create a small 32b mempool.
Everything works perfectly when dynamically linking with DPDK (pkg-config --libs).
However, when statically linking DPDK (pkg-config --libs --static), I observe weird runtime behaviors. Everything build and link without problem though.
The initialization of the EAL goes well, I can see that DPDK detect static linking in the logs, but creating any kind of mempool will return NULL and rte_errno is set to 2 (file not found).
I am confused as to what kind of magic DPDK is trying to do with static/dynamic linkage detection. As far as I can tell, all DPDK symbols that I use are defined in my statically linked binary.
