And if I fix this error I come to another file where I have to fix another error and so on. Therefore, I cannot simply include ctype.

Most of the issues related to using pktgen 22.04.01 with the latest DPDK 22.11.1 are referenced (indirectly, of course) in the DPDK release file, which can be found at doc/guides/rel_notes/release_22_11.rst (or here)

The main issue appears to be how they've reworked their BUS / PCI libraries, and correspondingly the headers.

There are two things you'll have to do differently than the basic setup steps:

1. build DPDK with the enable_driver_sdk option, e.g.:

    meson -Dexamples=all -Denable_driver_sdk=true build
    ninja -C build
    sudo ninja install

-Dexamples=all isn't necessary, but gives you the example programs. The crucial part is the -Denable_driver_sdk=true, which will add capability and install a few header files that wouldn't exist otherwise, e.g. bus_driver.h

2. Update their pktgen code so it compiles:

• lib/common/pg_strings.h: add #include <ctype.h>
• app/pktgen-port-cfg.h: comment out the line {RTE_ETH_RX_OFFLOAD_HEADER_SPLIT, _(HEADER_SPLIT)}, (It may be the case that RTE_ETH_RX_OFFLOAD_HEADER_SPLIT could simply be substituted with RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT, but that may be an incomplete fix. If you plan to offload RX header splitting to the hardware, you'll want to make sure this is properly working)
• app/pktgen-port-cfg.c: comment out .split_hdr_size = 0
• every file with #include <rte_bus_pci.h> (app/pktgen-latency.c, app/pktgen-port-cfg.c, app/pktgen-stats.c, app/pktgen-rate.c): add the following:

    #include <rte_bus.h>
    #include <bus_pci_driver.h>
    #include <bus_driver.h>
