Following the wiki/Building/MSWindows, we can get a 64-bit build environment with almost everything needed.
pkgconfig file for nvenc7
pkgconfig file for NVAPI
64-bit packaging improvements in r14814: we can have both versions installed now.
python ./configure.py --cuda-root="c:\\Program Files\\NVIDIA GPU Computing Toolkit\\CUDA\\v8.0"
/EHsc" and "
/FORCE" from siteconf.py.
BOOST_USE_WINDOWS_H=1 in EXTRA_DEFINES of setup.py to workaround this boost bug: http://stackoverflow.com/questions/18134148/
python ./setup.py build -c mingw32 python ./setup.py install
rm -fr build && python3 ./setup.py clean then repeat the build with python3.
Fails: does not build with mingw, not sure how easy it would be to fix (uses DX / MSVC macros)
--with-nvenc7should not be needed, nvenc should be detected automatically)
r14815 makes it possible to build the codec using Cython. Still TODO: the CUDA kernels cannot be compiled with nvcc and mingw, or at least I haven't been able to figure out how. (the documentation does seem to indicate that it should be possible) Options:
The gtkglext problem is upstream and is not in our (to be upstreamed) port of pygtkglext. Created a ticket for it: mingw-w64-x86_64-gtkglext DLL wrongly imports DllMain.
Found a solution: build gtkglext with "-mwindows", so we now have opengl with 64-bit builds! (PS: it seems that simply building from source is enough)
r14852 fixes the keyboard with 64-bit builds. (was a ctypes method signature error)
It's likely that there are other places where we should be more strict with C API signatures. 64-bit builds are more likely to expose these problems.
64-bit builds are also likely to be much faster at video decoding.
@afarr: over to you to find some bugs. Please bug smo to make sure you can reproduce these builds on your own environment.
Here's how to differentiate them from now on:
Alright, so I pulled down all three installers and gave it a whirl against a 2.0 r13454 server (latest package available on my Fedora 25 machine, for some odd reason sound is completely borked when I build from source - am investigating):
--opengl=no...which I was going to do anyways because Intel

But other than that it appears to work fine.
Appears to work fine, however there's a typo when importing gsview:
2017-01-25 14:43:42,215 Error initializing printing support: 2017-01-25 14:43:42,215 cannot find gsprint.exe in 'C:/Program Files (x86)/Xpra\gsview'
The last slash is a backslash not a forward slash.
Other than that seems to work fine.
Same error with gsview:
2017-01-25 15:09:02,451 Error initializing printing support: 2017-01-25 15:09:02,451 cannot find gswin32c.exe in 'C:/Program Files/Xpra\gsview'
Although I do wonder if it's possible to use the 32-bit gsview for printing
The session info does not denote what architecture the client and server are running, and since we'll be mixing 32 and 64 bit builds, it would make sense to put that information in the Session Info page.
Passing back to you - if you feel it's unnecessary, then go ahead and close (unless you have anything else that needs to be done) as I can't seem to find anything wrong with any of the builds. Anecdotally, video performance *feels* better because I can play FTL at a notably better FPS with the 64-bit build. I wish I had some hard data to back that up, but until then anecdotal evidence will have to suffice.
Performance is notoriously hard to measure.
Good point about the ability to distinguish builds, r15115 adds the "64bit" string to the about dialog.
pycuda update: had to do this to get pycuda 2019.1.2 to build on MSYS2:
pushd src/cpp ln -sf ../../bpl-subset/bpl_subset/boost pycudaboost popd pacman -S mingw-w64-x86_64-python3-mako mingw-w64-x86_64-python3-decorator
