cr1901_modernmithro: Any update on merging the litex changes? I'm currently blocked on that for the SD card stuff, among other things.19:07
cr1901_moderntravis was complaining about a missing tcl file19:07
mithrocr1901_modern: Probably not going to happen until the weekend19:08
cr1901_modernOkay... well, adding the spi flash config stuff is also kinda blocked. I guess in the meantime I'll look into conda/appveyor on Windoze19:09
mithrocr1901_modern: Start with openocd I think19:15
cr1901_modernmithro: Well the first thing I need to figure out is how to get prerequisite libraries that you expect the user to have installed already onto a windows machine19:18
cr1901_modern(like libftdi/libusb)19:18
mithrocr1901_modern: That might explain why I was adding libusb to our conda packages...19:22
tpbTitle: GitHub - mithro/conda-hdmi2usb-packages at libusb (at
cr1901_modernmithro: That was a bad example. I'm sure there are others :P19:23
mithrocr1901_modern: OpenOCD doesn't have a lot of dependencies?19:23
cr1901_modernNo... if memory serves, just libusb/libftdi19:24
cr1901_modernwhat I was getting at is that I agree that if your distro provides them, use the distro-provided libusb/libftdi19:24
cr1901_modernBut perhaps Windows should provide them as conda packages b/c the package management stuff on windoze, well kinda sucks19:25
cr1901_modern(not to mention we still need bash)19:25
mithrocr1901_modern: I'd hope to get rid of the bash dependency19:25
cr1901_modernmithro: Could we get rid of make as well possibly/swap to meson?19:26
cr1901_modernWell not now*19:26
mithrocr1901_modern: Potentially - but that is a pretty big ask19:26
cr1901_modernBut just thinking ahead19:26
mithrocr1901_modern: But yes19:26
cr1901_modernmithro: You are aware that there are two ABIs used for Windows, right?19:27
mithrocr1901_modern: Nope!19:27
mithrowell kinda but I don't really care19:27
cr1901_modernFair. Just thinking about whether to build on Windows or cross-compile via mingw.19:29
cr1901_modern Thank God19:30
mithrocr1901_modern: Being able to cross-compile via mingw would be a pretty big win19:30
cr1901_modernmithro: I will see what I can do, as I normally compile natively via mingw6419:31
cr1901_modernI don't have a problem w/ it, but need to experiment19:32
cr1901_modernI wish it were possible to see what files/dep an anaconda package provides19:33
cr1901_modern(without installing it)19:33
mithrocr1901_modern: FYI - You can just download the package and use tar to list the contents19:33
mithrocr1901_modern: The API here -> might have something a bit more useful?19:35
mithrowget -O- | tar -jvx info/recipe/meta.yaml -O19:36
cr1901_modernoh cool19:39
mithrocr1901_modern: I'd like to only upload a new build to anaconda when we actually changed something in which affected the package19:41
cr1901_modernWell I mean, we'll have to upload the windows versions of the packages. They're not uploaded yet!19:42
mithrocr1901_modern: This was more a reason why I was playing with the API / metadata in the meta.yaml file19:43
cr1901_modernmithro: Right now, I don't actually understand. What _is_ the current status of running HDMI2USB/litex-buildenv on Windoze, conda or otherwise?19:45
cr1901_modernI know without conda is unsupported period (although I do it anyway)19:45
mithrocr1901_modern: The only person who is doing it is you and xobs19:45
cr1901_modernWell presumably we're both using mingw64 (can't compile gcc w/o it)19:46
mithrocr1901_modern: Nope, xobs is using that compatibility layer thingy19:46

CarlFKso far I have only heard good things about it (bash on win)19:51
cr1901_modernI use 7, so I don't have access to it19:52
CarlFKoh, well that's a problem19:52

mithroCarlFK[m]: can't until I fixed the above issue that cr1901_modern1 was talking about21:56
CarlFK[m]k - just making sure it didn't slip past me, or get forgotten about21:57
mithroCarlFK[m]: Keep bugging me22:38
