Starting from DPDK 21.05, pkg-config becomes the only official way to build DPDK apps. Because of it go-dpdk uses #cgo pkg-config directive to link against your DPDK distribution.

Go compiler may fail to accept some C compiler flags. You can fix it by submitting those flags to environment:

export CGO_CFLAGS_ALLOW="-mrtm"
export CGO_LDFLAGS_ALLOW="-Wl,--(?:no-)?whole-archive"

• Only dynamic linking is viable at this point.
• If you isolate CPU cores with isolcpus kernel parameter then GOMAXPROCS should be manually specified to reflect the actual number of logical cores in CPU mask. E.g. if isolcpus=12-95 on a 96-core machine then default value for GOMAXPROCS would be 12 but it should be at least 84.
