I've downloaded the latest eclipse (.tar.gz) and unpacked it to /usr/bin and created a launcher for it, but it doesn't launch.
I also created a shell script on the desktop called eclipse.sh, content :
cd /usr/bin/eclipse
./eclipse

and did a chmod 755 /Desktop/eclipse.sh in a terminal as root.
I did a chmod 775 on the eclipse executable as well, but it still won't launch

NB I followed the same procedure with Bluegriffon and that runs OK.

I bet I'm missing something obvious, but just can't think what.

Box is AMD Phenom ll x4 / 8GB DDR3 running Mint 17.1 LXDE.

Is the file executable? (chmod +x ....)

chmod 755 makes it executable, I did that. - the 7 = R-W-X, the 5 = R-X

Have you java installed?

Have you followed the install instructions here: https://wiki.eclipse.org/Eclipse/Ins...to_use_the_JVM

It was something obvious - 64 bit version on a 32 bit distro - Doh!
