I solved my issue by making the following change: In file: src/include/all.mk (line 136) # ${Q}[ -e src/include/io ] || ln -s src/lib/io ${top_srcdir}/src/include ${Q}[ -e src/include/io ] || ln -s ${top_srcdir}/src/lib/io ${top_srcdir}/src/include Then it fails later, because of compilation warnings (I tried to configure with "--enable-werror"): CC src/main/map.c src/main/map.c: In function ‘map_list_mod_apply’: src/main/map.c:1679:3: error: this statement may fall through [-Werror=implicit-fallthrough=] { ^ src/main/map.c:1709:3: note: here case T_OP_ADD: ^~~~ src/main/map.c: In function ‘map_to_request’: src/main/map.c:2433:7: error: this statement may fall through [-Werror=implicit-fallthrough=] if (map->rhs->type == TMPL_TYPE_LIST) { ^ src/main/map.c:2438:3: note: here case T_OP_EQ: ^~~~ In file included from src/freeradius-devel/io/time.h:32:0, from src/freeradius-devel/clients.h:33, from src/freeradius-devel/radiusd.h:60, from src/main/map.c:31: src/freeradius-devel/rad_assert.h:43:30: error: this statement may fall through [-Werror=implicit-fallthrough=] # define rad_assert(_expr) ((void) ((_expr) ?

I go a bit farther now. Include issues, I guess: CC src/protocols/dhcpv4/decode.c In file included from src/protocols/dhcpv4/decode.c:33:0: src/freeradius-devel/dhcpv4/dhcpv4.h:145:1: error: unknown type name ‘RADIUS_PACKET’; did you mean ‘AF_PACKET’?
