Implicit declaration warning:
../lib/librte_eal/windows/eal.c:371:6: warning: implicit declaration of function 'rte_service_init' is invalid in C99 [-Wimplicit-function-declaration]
        if (rte_service_init()) {
            ^
1 warning generated.

Adding "#include <rte_service_component.h>" in windows/eal.c should solve it.

Getting some linker error:
   Creating library drivers\librte_bus_vdev.dll.a and object drivers\librte_bus_vdev.dll.exp
bus_vdev_vdev.c.obj : error LNK2019: unresolved external symbol rte_log_register_type_and_pick_level referenced in function __vdev_logtype_bus
drivers\librte_bus_vdev-0.200.3.dll : fatal error LNK1120: 1 unresolved externals

Probably just a missing export for "rte_log_register_type_and_pick_level" in rte_eal_exports.def?

After adding the missing include and export, compilation and linking are successful.
I see some errors when running the app though:

EAL: error allocating rte services array
EAL: FATAL: rte_service_init() failed
EAL: rte_service_init() failed
PANIC in main():
