I think the key is to generate the liblua51.dll.a file using the
instructions that were just posted, and stick that into the pdlua
folder, set -L., then -llua51 should just work. The .dll.a file seems
to expose the DLL symbols in a way that ld understands. If that
works, I'll include it in the build machine.

I just built that lua-5.1.4 package in MinGW.
Just typing 'make mingw'produces liblua.a and lua51.dll in src.
liblua.a is somewhat larger than the dll.
'Make install' copies liblua.a into /usr/local/lib and creates an
empty directory /usr/local/lib/lua.
The error in the latest autobuild log
(2011-03-27_03.31.00_mingw32_nt-5.1_windowsxp-i386_pd-extended.txt) is

\ld.exe: cannot find -llua51.dll
So maybe it should be looking for -llua instead of -llua51.dll.
Or else placing lua51.dll in /usr/local/lib or /usr/local/lib/lua
might work. The lua wiki seems to imply that you should link against
the dll.
I'll change it to -llua first as that seems consistent with the rest
of the MinGW Pd build.

Hmm, turns out it was already installed on the Windows build machine,
but I just updated it. Something with the way pdlua is being linked
makes it not able to find lua51.dll. My guess is because the Lua
build
system doesn't generate a liblua51.dll.a to put in /usr/local/lib,
like
the other libs there. libogg for example. I don't know how to
generate
the liblua51.dll.a, do you?

If you get the latest source here:

Yeah, we can build Lua on Windows and install it into the MinGW
path.
That's how the rest of the libraries are currently handled. Then
the
installer grabs the .dlls from the MinGW install path.
Have you successfully built Lua on Windows? If so, let me know the
details, and I'll install it on the build server.

From the gnu make manual it seems that running pkg-config is not
recommended inside a Makefile. It should probably be done in the
configure stage, but anyway, since liblua has different names on
each
platform, pkg-config only returns that name.
So I ended up just hard-coding liblua names and lua.h path for
each OS
in the Makefile.
Now the nightly build for Windows is failing because it can't
resolve
-llua51.dll. It seems that there is no standard place to put
that dll.
Sooo, maybe pd-extended should build lua as well, like
portaudio, or
should the dll be put in pd/bin, like pthreads.dll?

Martin,
I think you could put different pkg-config lines in the per-OS
section
of the Makefile, and that would work for differences between
Debian/Ubuntu, Mac OS X, and Windows liblua. That won't help if
different GNU/Linux distros have different names for the lib tho.

Hello,
In the original Makefile.static for pdlua it is defined:
lua-5.1.3
This worked for me on OSX.

From my limited experience, Lua 5.1 libraries have different

all over the place, even in different GNU/Linux distros (lua51,

"pkg-config lua --libs" should do it on Mac OS X/Fink.
