I just unpacked DocFetcher-1.6 Portable on some samba mount and tried to start from a Linux box on the command line. Instead of starting, the program stopped with UnsatisfiedLinkError complaining about swt-gtk (sorry, again). The Linux is Ubuntu 12.04 Precise 64 bit. The Java is openjdk-6 64bit.

$ ./DocFetcher.sh

Any further information I should provide?

Discussion

  • Sorry, I solved it myself: Turns out I didn't have write permission in the Samba folder where DocFetcher is installed. Starting ./DocFetcher.sh while having write permission in that folder worked fine.

    (Note for the great developers of this excellent software: This is something you could explicitly check for during startup..)

    Thanks, I'll see what I can do about it.
