Interesting. Bo's README suggests that "all" doesn't depend on "po".What happens if you specify individual targets:boost, intl, support, mathed, insets, frontends, graphics, controllers, client, qt3, qt4, lyxbase
I can get it to compile with the target 'install', but lyx.exe crashes immediately.
Did anyone succeed to build LyX with MSVC 2005? Joost
