Thanks. Shouldn't we then add a cygwin target as below?
$(MAKE) "CC=gcc -mno-cygwin" mingw
This would be a misnomer, but you may want to do it anyway.
No, because in this case, mingw is still the target; Cygwin just happens
to be the build environment. With the s/gcc/$(CC)/ change, the Makefile
basically doesn't care if you are building the mingw target using a
MinGW build environment or a Cygwin build environment, and this works
out just fine.
[ I guess this requires an explanation:
In addition to all of Mike's good information, I'd like to add that
''make posix'' works just fine for the Cygwin target.
Unless you want readline support or you want to build shared objects
(DLLs) instead of a static library. But then most people building Lua
from source could figure this out. The rest should be able to use
LuaBinaries, I should think. ;)
For those who can't or don't want to figure this out, the following
build configuration works for me:
$(MAKE) "LUA_A=lua51.dll" "LUA_T=lua.exe" \
"AR=$(CC) -shared -o" "RANLIB=strip --strip-unneeded" \
"MYCFLAGS=-DLUA_USE_POSIX -DLUA_USE_DLOPEN -DLUA_BUILD_AS_DLL" \
"MYLIBS=-lreadline -lhistory -lncurses" "MYLDFLAGS=-s" lua.exe
It's not particularly important to me to have this added to the
distribution, I just wanted to provide it here.
As an aside, it seems that no Cygwin header declares _longjmp/_setjmp,
but glibc defines them and they seem to work. Otherwise, there are no
other build warnings. Nice!
