It looks like Lua puts the commands to 'ar' into the AR variable. Your build environment or configuration sets the AR variable to the appropriate binary for your system, overwriting these commands. Then when building, ar complains that it's missing a valid command. As a workaround, here's a patch that ought to solve it: diff --git a/liblua/Makefile b/liblua/Makefile index d71c75c..ee52283 100644 --- a/liblua/Makefile +++ b/liblua/Makefile @@ -11,7 +11,7 @@ CFLAGS= -O2 -Wall -Wextra -DLUA_COMPAT_5_2 $(SYSCFLAGS) $(MYCFLAGS) LDFLAGS= $(SYSLDFLAGS) $(MYLDFLAGS) LIBS= -lm $(SYSLIBS) $(MYLIBS) -AR= ar rcu +AR= ar RANLIB= ranlib RM= rm -f @@ -56,7 +56,7 @@ o: $(ALL_O) a: $(ALL_A) $(LUA_A): $(BASE_O) - $(AR) $@ $(BASE_O) + $(AR) rcu $@ $(BASE_O) $(RANLIB) $@ $(LUA_T): $(LUA_O) $(LUA_A) I'll see what I can do to get this fixed in upstream Lua.

The lua version on the OpenWRT device that is being used is Lua 5.1.5. Trying with the "--with-liblua=included" option, it tried to compile liblua, however it still failed with the attached error log. But it seems some progress were made. Do you have any other suggestions I could try? Thanks Daniel On 04/05/2018 10:30 AM, Daniel Miller wrote: Bruno, Thanks for following up. It appears that you might have a version of Lua installed that is incompatible with Nmap. You can force Nmap to build and statically link the Lua 5.3.3 source that's included with Nmap by passing --with-liblua=included to configure. Let us know if this fixes the issue for you.

If it doesn't I will reply with the error on clear text). Compiling with the "--without-liblua" works flawlessly.

However, there shouldn't be any reason that it wouldn't compile on OpenWrt. Can you change the package's makefile so that it doesn't use --without-liblua in configure and then report what actually happens? What are the specific errors that happen?

I'm trying to run nmap scripting on OpenWRT, so the router let me know if there are vulnerabilities on my network to be patched. However, the nmap version for OpenWRT is missing scripting support ( https://github.com/openwrt/packages/issues/4472) The scripts are written in lua. So, what I'm planning to do is run all the scripts available from lua itself. Do I have to rewrite part of NSE or is there an easy way to do it? Or is there a way to enable scripting on OpenWRT with liblua?
