[Angstrom-distro-users] Java and AWT

[Carlos Torrejón Sampedro]

Hi!

I just write to tell you how I "solved" my problems or where did they 
come from.

After installing gpe, I finally decided to use ipkg  in console mode 
because I didn't like GPE Program Manager. When I was installing some 
classpath y realize that "file" dependant package was telling me thath 
couldn't be configured. That made ldconfig not to work properly and 
because of that I had all my problems.

After checking that problems I realize that my repositories were mixing 
2007 and 2008 packages.That made to fail configuring dependant packages.

I hope someone having same problem, can find this post and solve his 
problems.

Thank you very much Oliver. Your comment about ldconfig made me work in 
the right way and check dependant packages. Thank you very much again.

Regards,

Carlos Torrejón.
