Re: luarocks on WinXP and minGW/msys fails

[Vyacheslav Egorov <mister.aleph@...>]

I've recently tried LuaRocks in my customized Lua-environment (Win32,
MinGW) and discovered that it almost unusable (by "unusable" I mean
that I had to patch here and there to make it work. Maybe my build
environment is just insane, so it is not LuaRocks' fault, but
mine...). There were several reasons:

I have lua51.dll (this name is used in _official_ Lua Makefile), but
all binary rocks depend on lua5.1.dll. So, I had to patch LuaRocks so
it will prefer source rocks to prebuilt ones;
Unfortunately, it is common for the source rocks to have a

win32 { build_pass = true }

in their rockspecs, so I had to unpack rock and manually change rockspec...

But then I discovered that rocks use Makefiles, instead of some
os-agnostic lua-based build engine! Even more, Windows makefiles use
MSVS as if it is the only compiler under Windows.

There also were several obscure bugs (probably related to MinGW's
back-slash intolerance), e.g. generated orbit.bat contained the
following path:

"D:/Tools/Lang/Lua/lua-5.1.2/bin//D:\Tools\Lang\Lua\lua-5.1.2\bin\\lua.exe"

LuaRocks also does not expect to find MinGW tools (e.g. mkdir) in PATH
instead of it's own tools. I had to insert some kludges into fs.win32
to convert '\' to '/'.
