Hi!

yesterday i have managed to compile Gem on W32 (surprisingly
simple that was)

Can I ask which compiler do you use on w32?

Micro$oft Visual Studio 2003 (i know it's outdated, but it's the newest VS we have here at the university; gcc rulez)

Shall we try to switch the Gem build to MinGW? Then we'll have
automated builds, and you'll be able to make Gem Windows binaries by
cross-compiling on GNU/Linux.

this version has been compiled with DirectShow9 and QuickTime7.2
support. support for tablets has been further removed.

I guess they have to be both installed for having Gem loading.

you don't need QuickTime installed; it will be autodetected on load
and used accordingly. i don't know about DirectX, but i guess you will need it beforehand.

note: i should have written DirectX-9 instead of DirectShow-9 to avoid confusion.

please test and report any bugs.

Thank you, I'll give many tries!

cool :-)

if you feel up to it. i currently don't really want to spend time in getting code compile against DirectX with mingw. (for Gem you also have to compile parts of the DirectShow examples)

There are already a lot of DirectX headers in MinGW, you might not
need the DirectX SDK at all. I didn't need the Windows DDK for the
HID stuff, all of the headers I needed are included in MinGW. These
look all relevant:

direct.h dxerr8.h dxerr9.h d3d9.h d3d9caps.h d3d9types.h

i also would not like to have a stripped down version of Gem (without DirectX and QuickTime) compiled and widely distributed.

and you would have to change your policy of importing code to repositories, as i don't think importing DirectX-SDK (some versions of which you can only download from a "genuine windows machine" (or
however they call it)) and Quicktime-SDK (for which you currently need an
apple user-account to download) would be a good idea.

These would have to be installed on the build machine. We couldn't
include them in the SVN. Just like the Apple builds require XCode.
I am guessing it would only be the Quicktime SDK that we'd need to
install.

nevertheless it would be cool if you could include the new binary into the next pd-extended release.

hmm, i don't know. this is what get's included by the relevant files: dshow.h qedit.h streams.h atlbase.h atlconv.h dvdmedia.h

if they are in mingw, i would be happy.

These are:

dshow.h qedit.h dvdmedia.h

These are not:

streams.h atlbase.h atlconv.h

There are people building DirectShow apps on MinGW, but I don't know
how involved the setup is:

yes, i am only talking about the SDKs here (XCode is an IDE, isn't
it?): packages providing header-files to include and library-files
to link against. nothing that fummels with the registry or the like. it's fine if we don't have to include them in the pure-data svn.

iirc, last time someone was trying to build gem4win32 with mingw/ cygwin (i think it was thoralf; but i could be mistaken - excuse my
ignorance), they had to patch the DirectShow-headers...

Quoting chris clepper cgclepper@gmail.com:

Those look outdated since they are referring to DirectShow still being part of DirectX.

otoh, i used DirectX-9.0 too for my builds. i guess i haven't really
understood the versioning scheme of M$....

GEM doesn't need DirectX, rather it requires DirectShow. DirectShow is part of the massive windows SDK and the DLLs are supposedly part of a default install of XP and Vista (I have never even used the latter).

i never understood the difference between DirectX and DirectShow. isn't the latter just a part of the former? just like Direct3D?

anyhow, at least when installing the SDK i had to also install a redistributable runtime-environment. i don't know whether this is needed for an end-user of Gem too (my only w32 machine now has the runtime-environment installed, so i cannot check :-))

These would have to be installed on the build machine.  We couldn't

Yes, just the QT SDK is needed.

i probably misunderstood the original question. right, as far as quicktime is concerned, only the QT SDK is needed.
