# Building apps

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"

```

# Caveats

* 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.
