Hi,
I'm taking a shot at building Lua with Clang on Windows and I'm stalled out on modifying the standard Lua makefile. I've tried both the GNU Win32 Make (3.8.1) and Digital Mars Make (It came with DLang). All the below work is with GNU Make.
To modify the Makefile for Windows, I changed CC = clang. Then I've replaced *.o with *.obj in the file and created a new target called clang which looks like this (full modified makefile here:
https://pastebin.com/BXGvrPiD)
clang:
$(MAKE) "LUA_A=lua53.dll" "LUA_T=lua.exe" \
"AR=lib" \
"SYSCFLAGS=-DLUA_BUILD_AS_DLL" "SYSLIBS=" "SYSLDFLAGS=-s" lua.exe
$(MAKE) "LUAC_T=luac.exe" luac.exe
mingw:
$(MAKE) "LUA_A=lua53.dll" "LUA_T=lua.exe" \
"AR=$(CC) -shared -o" "RANLIB=strip --strip-unneeded" \
"SYSCFLAGS=-DLUA_BUILD_AS_DLL" "SYSLIBS=" "SYSLDFLAGS=-s" lua.exe
$(MAKE) "LUAC_T=luac.exe" luac.exe
The above is my attempt to modify the mingw target which I have also included for reference. I've tried the clang target with -shared and -o left in and removed, both with no success. This is the result of my latest attempt with -shared and -o left in:
C:\Users\russh\lua\lua-5.3.5\src> make clang
make "LUA_A=lua53.dll" "LUA_T=lua.exe" \
"AR=clang -std=gnu99 -shared -o" \
"AR=lib -shared -o" \
"SYSCFLAGS=-DLUA_BUILD_AS_DLL" "SYSLIBS=" "SYSLDFLAGS=-s" lua.exe

It seems to me to be missing the compile step and going straight to the link step?
Any input would be appreciated.
