Re: [Minios-devel] [UNIKRAFT/LIBLUA PATCH 0/3] support for the lua language

["Justin He (Arm Technology China)" <Justin.He@xxxxxxx>]

Hi Felipe
Besides, I found another 2 issues:
1. some head files are missing after fetching the liblua src codes
root@jong:~/hj/UK/apps/helloworld# ll  
/root/hj/UK/apps/helloworld/build/liblua/include/
total 28
drwxr-xr-x 2 root root 4096 9月   2 12:52 ./
drwxr-xr-x 4 root root 4096 9月   2 12:53 ../
lrwxrwxrwx 1 root root   71 9月   2 12:52 lauxlib.h -> 
/root/hj/UK/apps/helloworld/build/liblua/origin/lua-5.3.5/src/lauxlib.h
lrwxrwxrwx 1 root root   71 9月   2 12:52 luaconf.h ->

lrwxrwxrwx 1 root root   67 9月   2 12:52 lua.h ->

lrwxrwxrwx 1 root root   70 9月   2 12:52 lualib.h ->

root@jong:~/hj/UK/apps/helloworld# ll

ls: cannot access 
'/root/hj/UK/apps/helloworld/build/liblua/origin/lua-5.3.5/src/lauxlib.h': No 
such file or directory
root@jong:~/hj/UK/apps/helloworld#

I guess something wrong in Makefile.uk
# TO_INC
UK_PREPARE += $(LIBLUA_BUILD)/include/lua.h
UK_PREPARE += $(LIBLUA_BUILD)/include/luaconf.h
UK_PREPARE += $(LIBLUA_BUILD)/include/lualib.h
UK_PREPARE += $(LIBLUA_BUILD)/include/lauxlib.h
UK_PREPARE += $(LIBLUA_BUILD)/include/lua.hpp

2. seems liblua can't be built with nolibc enabled, no signal.h is found

3, with newlib enabled, the helloworld app (almost dummy main()) can't
be linked:
