After some searching on the forums, it appears that my problem is quite frequent, but I can't seem to get it solved. I am running JDK6 on Ubuntu 9.10 64bit. I have set up everything like the lejos 3.0 README said, but when I go to run checkDistribution.sh I get this:
- Code: Select all

So, how do I get this lib into the java.library.path?
I tried a possible solution I found on the forums which said to compile the code under the /home/bits/lejos/src/comms/libjirtrcx, but when I do that I get an error that says that jni.h cannot be found.
- Code: Select all
bits@bits-laptop:~/lejos/src/comms/libjirtrcx$ make

make: *** [/libjirtrcx.so] Error 1
I've never coded in C, so I don't know how to solve that one.
Thanks for any help!

I solved this problem. Solving it was rather tricky, so I may post a little tutorial on how to do it.
