Hi -- I installed phenix-installer-1.6-289-intel-linux-2.6.tar on my Fedora Core 5 linux partition and most things run -- but not solve (which I was first trying from autosolve). As recommened by the documentation, when I type phenix.solve, here's what I have --- [root@ausinger oth32_c]# phenix.solve binary=/usr/local/phenix-1.6-289/build/intel-linux-2.6/solve_resolve/exe/solve SOLVEDIR=/usr/local/phenix-1.6-289/solve_resolve/ext_ref_files SYMOP=/usr/local/phenix-1.6-289/solve_resolve/ext_ref_files/symop.lib SYMINFO=/usr/local/phenix-1.6-289/solve_resolve/ext_ref_files/syminfo.lib CCP4_OPEN=UNKNOWN SOLVE_RESOLVE_MALLOC_MAX=1862380800 /usr/local/phenix-1.6-289/build/intel-linux-2.6/solve_resolve/exe/solve: error w hile loading shared libraries: /usr/local/phenix-1.6-289/build/intel-linux-2.6/l ib/libimf.so: cannot restore segment prot after reloc: Permission denied Do you know what I can do about this?
