I’ve been looking at some web java-based screencasting apps, namely screenr and Screencast-o-matic, which look suspiciously similar. I wanted to record a voiceover along with a screencast, but couldn’t get it to work – on a Windows 7 x64 machine with 64-bit Java 7 installed (as well as I think 32-bit Java 7).
Long story short, the only way I could get either tool to recognize the fact I had any sound recording devices at all was to run it in Internet Explorer 64-bit (heaven forbid!). Hopefully this helps someone – if you know why this is, I’d be curious to find out.
Boost is a great set of libraries that is pretty generally available – on Linux, that is. On Windows, though there are installers available, I tend to have better luck building it myself, though I always need to go digging for the instructions I wrote “last time” I built it. So, here for my reference and yours, is how I build Boost, for Visual C++ version X: (pretend it’s all on one line)
bjam --build-dir=vcX toolset=msvc-X.0 architecture=x86 link=shared
threading=multi runtime-link=shared variant=debug,release
--without-mpi --prefix=boost-vcX-install stage
For a 64-bit build, I add “x64” to all directory names, and this parameter:
