I have finally managed to build Windows installers for 2.3.0. They can be found here:
http://ftp.lyx.org/pub/lyx/devel/lyx-2.3/ Let me emphasize again that THESE ARE FOR TESTING ONLY!!!! I have tested them a little bit myself, but not a whole lot. They seem to work, basically---I compiled the tutorial---but that's as far as I'm going to go in vouching for them. My understanding of the installer code is pretty basic at this point. The executables were cross-compiled using MinGW on Linux. So these are not at all the same binaries that we have previously been distributing. The installers themselves, however, are pretty much the same, though without the "Update MiKTeX" code, which has just been commented out. If we want to include it, but issue some kind of warning, then I think that will need to be translated. I know where to put the translated strings, but I'm not entirely sure how to get them from the translators, and that will of course take time. Longer term, I have some thoughts about how to improve our situation on Windows, and there's been vigorous discussion over on the user list. But I'll save that for after we get an installer for 2.3.x. Riki PS Certainly one thing I've learned is that installing LyX with MikTeX takes *forever*, and I've got a fast internet connection. It would be nice to know what packages we need to install to compile the User Guide, etc, and just install those, rather than every single package LyX could possibly need. This is not trivial, since some of those are font definitions.
