Hi -- I was installing the latest version of CCP4 6.2.0 on my machine which uses Linux Fedora Core 5. When downloading the CCP4 package, I used the 'generic linux (x86) option'. The package contains an package for Coot v 0.6.2 which I tar'ed and uncompressed, but when I try to run it, I get this error ./coot-real ./coot-real: error while loading shared libraries: libgio-2.0.so.0: cannot open shared object file: No such file or directory ./coot: line 254: 16409 Floating point exception$COOT_PREFIX/bin/guile -s $COOT_PREFIX/share/coot/scheme/coot-crash-catcher.scm $coot_real $* Do you know how I can overcome this problem?
