Hi,

I went to http://www.mentor.com/embedded-software/codesourcery and downloaded ALL versions of toolchains and tried them ALL with kindlepdfviewer. These are my findings.

First, I tried the oldest, 2005q1b. Luajit reported error - it needed at least gcc 4.2. So, I skipped versions before 2007q1-10, since the 2007q1-10 was the first to have gcc 4.2. All other versions, 2007q1-10 to 2012.03-57 compiled without errors, with the exception of 2008q1-126. It didn't compile at all. It reported this:

Of those that did compile, zips compiled with 2007q1-10, 2007q1-21 and 2007q3-51 worked on Kindle "out of the box". The rest of them didn't (I suppose they need sysroot).

I also tested linaro that comes with Ubuntu again. This time it compiled (thanks to dave2008's Makefile fix), but of course, it didn't work on Kindle (Again, I suppose it needs sysroot).

Since twobob said that 2008q1 is "the last TC that compiles natively (Runs applications without replacing the onboard system libraries) for the Kindle 3", any idea why it is the only version that didn't work with kpdfview?
