I assume that ‘me’ here is really ‘hossening’ so the real change to is /home/hossening/lua/liblua.a right? I worry that you have mis-spelled on of the lines. The code linked compiled so it found the include, but not the lib. Check and make sure you did not mis-spell something here. > > > Replacing > > *MYLIB_PATH += -L$(LUA_LIB) $(shell pkg-config --libs-only-L lua5.3)* > > with > > *MYLIB_PATH += -L$(LUA_LIB) **-L:/home/me/lua/liblua.a* > > > Replacing > > *CFLAGS += -I/usr/include/lua5.3* > > with > > *CFLAGS += -I/home/me/lua/include* > > > In *lib/lua/Makefile*: > > Replacing > > *CFLAGS += $(shell pkg-config --cflags lua5.3)* > > with > > *CFLAGS += -I/home/me/lua/include* > > > Replacing > > LDLIBS += -L$(SRCDIR)/../lua/$(RTE_TARGET)/lib -llua > > with > > LDLIBS += -L$(SRCDIR)/../lua/$(RTE_TARGET)/lib > -L:/home/hosseing/lua/liblua.a > > > > Then, when I make Pktgen, I receive thousands of errors, like this: > */home/me/pktgen-3.5.9/app/../lib/lua/x86_64-native-linuxapp-gcc/lib/libpktgen_lua.a(rte_lua.o): > In function `msghandler':* > */home/me/pktgen-3.5.9/lib/lua/rte_lua.c:244: undefined reference to > `lua_tolstring'* > */home/me/pktgen-3.5.9/lib/lua/rte_lua.c:257: undefined reference to > `luaL_traceback'* > */home/me/pktgen-3.5.9/lib/lua/rte_lua.c:247: undefined reference to > `luaL_callmeta'* > */home/me/pktgen-3.5.9/lib/lua/rte_lua.c:248: undefined reference to > `lua_type'* > */home/me/pktgen-3.5.9/lib/lua/rte_lua.c:252: undefined reference to > `lua_type'* > */home/me/pktgen-3.5.9/lib/lua/rte_lua.c:252: undefined reference to > `lua_typename'* > *...* > > The included Lua header files seem to be OK.
