The file /usr/local/bin/fpc should be used as compiler executable if it can't be found in $SDKHOME/bin. Does it exists? No symlink should be needed.
Most basic types are declared in system.ppu. FPC 2.6.4 doesn't has ppudump with XML output capability therefore system.ppu can't be parsed. The only way to fix this is to use newer FPC version.
As of EAccessViolation - I encountered it myself. Some version of FPC can't handle empty parameters. It's was fixed in newer FPC versions. As a workaround (besides switching to newer FPC version) you can set something in "additional compiler options" field in SDK settings. E.g. "-O3".

The usage of the plugin is to effectively write and analyze code. It's ideal for cases when no GUI design needed - game development or server programming. But even for GUI applications the plugin can be used to write code.
After programming in such IDEs as Eclipse and especially IDEA I'm not satisfied with usability of existing Pascal IDE's in writing code anymore. It's hard to explain to someone who didn't try IDEA (I didn't believe it myself
). May be some video demos can explain better.
