Hmm, Ubuntu 64bit binaries were working fine for me on Linuxcoin up until now, 1.6.0 won't start. Is this because of the make install changes? Do I have to run make install from the directory, even for the binary release? And where do the files end up, where do I put configuration files, and what about newer versions? Will these automatically overwrite the previous binary from now on?
No it should just work from the directory like it always did. HOWEVER if you have old .cl files in /usr/bin it might be using those. If you do make install with the binary version it will end up in /usr/bin (that's why I included the entire build tree this time instead of a stripped down tarball).
