Also, sharp/cacko roms are just ipk, pdaxrom say armv5tel.ipk at the end.
I do have a lot of other tricks on that installation guide I posted above, suggestions for making sure you have the right ones.
Also there is a command that checks to see if you have all the right dependencies, the right libraries,
http://elsix.org purports to feed you links to the OS you say you have, I am not sure how good that facility is.
But you can also run the ldd command to see if you have all the dependencies:
http://sdjf.esmartdesign.com/commands/ldd.htmlIf there are missing libraries, it will tell you, and then you check the feeds or even better just stick the library name into google and see what sites come up.
Any file I link to from my site says in the writeup if it works on the early Sharo ROMs I run, but I don't have pages about all that many apps, just ones I was inspired to write about.
