I like the new release for the most part, but my *compressed* image is now 80k larger than my 21_rc4a build, which makes me sad and. Is there some low hanging fruit I can disable to trim that down? My program is now 20k over my 512k limit

[thomastaranowski]

Ok, my bad. There were some stale files in the html directory that got pulled in. It's still 20k larger though, so tips would be appreciated

Under the project compiler settings you could try the Optimize for Size (-Os) setting and see what happens. Also depending on the size of your HTML/CSS/Javascript files I've found that running the optimizers that strip out all the non-essential whitespace can have an effect. Of course then you have to keep two copies of those files around because they are VERY hard to work with once all the whitespace is gone. And in JS files some of the optimizers require that every line end with ; or the optimized code won't run correctly.

By default support for exceptions and RTTI is off, you can make sure those boxes aren't checked (Under the C++ Compiler settings Miscellaneous section).

Tod,

Thanks for the reply. I'm already doing -Os If I recall, it made about a 10-15% difference at the time.

I was using the yuicompressor as part of my web development toolchain prior to building the netburner image, but I've switched to using htmlcompressor now, as it compresses the html as well (http://code.google.com/p/htmlcompressor ). The only issue I had was I had to disable comment compression, otherwise my <!-- FUNCTIONCALL --> tags would be stripped out. It's been working reliably for several months now, and saved me about 15-20k of space.
