I finally got to install Dropbox on linux. It’s made for Nautilus (Gnome) so it didn’t work in Mandriva 2009.0. I couldn’t compile the source for some obscure reason (as usual) so I sent them a mail to ask them where I could download the daemon only. Less than 24 hours later, I got the answer:
DropBox daemon Linux 64bit
DropBox daemon Linux 32bit
Dolphin (KDE 4) didn’t require any special config whatsoever, it just worked right away.
I also installed it on my EeePC 901. It also worked but I had to start the process in a shell and leave the shell open to keep the process alive. I’ll have to figure out how to start a process as a service on this little-too-simple linux.
