Hi everyone, I am using Scientific Linux 5.5 and I have two little problems right now. 1. After enabling rpmforge-extra repository, I did yum update but there were errors like ---------------------- Loaded plugins: downloadonly, kernel-module, priorities 280 packages excluded due to repository priority protections Setting up Install Process Package tcp_wrappers is obsoleted by tcp_wrappers-libs, trying to install tcp_wrappers-libs-7.6-57.el5.rfx.i386 instead Resolving Dependencies --> Running transaction check --> Processing Dependency: tcp_wrappers for package: nfs-utils ---> Package tcp_wrappers-libs.i386 0:7.6-57.el5.rfx set to be updated --> Finished Dependency Resolution 1:nfs-utils-1.0.9-44.el5.i386 from installed has depsolving problems --> Missing Dependency: tcp_wrappers is needed by package 1:nfs-utils-1.0.9-44.el5.i386 (installed) Beginning Kernel Module Plugin Finished Kernel Module Plugin Error: Missing Dependency: tcp_wrappers is needed by package 1:nfs-utils-1.0.9-44.el5.i386 (installed) You could try using --skip-broken to work around the problem You could try running: package-cleanup --problems package-cleanup --dupes rpm -Va --nofiles --nodigest ---------------------- 2. I found octave was not in SL 5's repository by default. I tried to compile it from source but got stuck at GNU readline libraries: ------------ configure: WARNING: I couldn't find -ltermcap, -lterminfo, -lncurses, -lcurses, or -ltermlib! checking for rl_set_keyboard_input_timeout in -lreadline... no configure: WARNING: I need GNU Readline 4.2 or later configure: error: this is fatal unless you specify --disable-readline -------------- I grabbed readline's latest source from http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html , compiled and installed with default configuration. But the error still exists. Or is there a repository containing Octave that is friendly to SL5 ? Could you please help? Thanks.
