Re: Proxy DLL for Lua 5.1; can't get it to work with statically linked liblua

I tried that, but couldn't get it to work either. When I use
-DLUA_API=__declspec(dllexport), it's overwritten by #define LUA_API
extern in luaconf.h (so symbols don't get exported). When I use
LUA_BUILD_AS_DLL, which should have the same effect as setting
LUA_API, I get bunch of "undefined reference to `_imp__lua_sethook'"
warnings.

You suggestion made me to review the related code one more time and it
turned out that I also need to set LUA_CORE or LUA_LIB along with
LUA_BUILD_AS_DLL to get LUA_API properly assigned.

Here is the makefile target that works for both Lua 5.1 and Lua 5.2
(you may want to disable redefine warning with -Wp,-w):

"$(MAKE)" "LUA_T=lua.exe" \
"AR=$(AR) -o" "RANLIB=strip --strip-unneeded" \
"MYCFLAGS=-DLUA_CORE -DLUA_BUILD_AS_DLL" lua.exe
