I am basically trying to compile your code

The following is where I have reached: (I am sorry if the steps I am following may be completely wrong as I am new to C and GCC in general, I am just trying my best to bring this puzzle together)

It has two dependencies:

https://github.com/andlabs/libui
Lua from https://www.lua.org/download.html
I was able to generate two files from the above 2 projects:

liblua.a
libui.a
I was happy so far, but I am not able to figure out how to use the above .a files and compile the zhaozg/lui project.

The instructions on compiling are as follows:

gcc -shared -Isrc src/lui.c -I{LUAINCDIR} -I{LIBUVINCDIR} -lui -llua-5.1 -o luv.so
Also, I am trying to keep the compiled files locally and not have them copied all over /usr/local

So, After a few hours, I reached the following step:

gcc -shared -v -Isrc src/lui.c -I ../lua-src -I ../libui /Users/silva/Documents/test00x/lui/liblua.a /Users/silva/Documents/test00x/lui/libui.a
But now I am stuck at the following error:

gcc -shared -v -Isrc src/lui.c -I ../lua-src  -I ../libui   /Users/silva/Documents/test00x/lui/liblua.a  /Users/silva/Documents/test00x/lui/libui.a

ok some more progress,
looks like this library isn't tested with Lua 5.3 as it says.
I replaced "luaL_checkint" with "luaL_checkinteger" and now I have only one error message which I am trying to solve.

ok __i64toa is not a standard function and hence doesn't work on most compilers.
I just copy pasted the implementation of __i64toa(from WINE) and it worked perfectly

now I have a lui.so using the following command

gcc  -o lui.so  -shared  -framework Foundation -framework AppKit -fPIC -Isrc src/lui.c -I ../lua-src  -I ../libui  -L . -llua -lui

but when I import it, I get the following error

lua: multiple Lua VMs detected
stack traceback:
	[C]: in ?
	[C]: in function 'require'
	controlgallery.lua:3: in main chunk

On Unix you shouldn't link the Lua library when building.

See here:

Do Not Link Modules to the Lua Core Libraries

Although it may be tempting to link modules against the static libraries containing the Lua core (lua*.a), this is not a good idea.

Essentially you are adding a copy of the whole Lua core (or at least large parts of it) to every module. Apart from being a waste of space this may lead to very difficult to diagnose problems. The different instances of the core code don't know anything about each other and may not necessarily be in sync.

In case you built a shared library containing the Lua core (*), please do not link any modules against it, too. I.e. do not specify the name of the Lua core library on the linker line (Windows DLLs are an exception). This makes a hard forward dependency where you really want a lazy backward dependency. Loading this module with a statically linked Lua interpreter would essentially drag in a 2nd Lua core and you get the same problems mentioned above.

In 5.3, you get that multiple Lua VMs detected error. In 5.1, you'd just get really weird behavior and crashes.

EDIT: Also, on Mac, you should add the compiler flags -undefined dynamic_lookup (see the Mac OS X shared libraries (Lua 5.1.3 and later) section in the link above)

Aha!
That worked perfectly!
Thanks a Million!!! I spent my entire day on this.

for everyone else, the command for Mac/Unix is:
gcc -o lui.so -shared -framework Foundation -framework AppKit -fPIC -Isrc src/lui.c -I ../lua-src -I ../libui -L . -lui -undefined dynamic_lookup
