Hi, I ran into couple of hiccups when using the install script on Ranger, so I thought I'd share. The first is that "svn export" doesn't work with the version of Subversion on Ranger (1.1.4). At least, I'm using it's a version issue, since the command works on my laptop with version 1.4.6. Here's the error: login3$ svn export http://svn.enzotools.org/yt/trunk/doc/ install_script.sh svn: REPORT request failed on '/yt/!svn/vcc/default' svn: Cannot replace a directory from within I don't think this is very big deal, but it may be worth mentioning on the Wiki that "wget http://svn.enzotools.org/yt/trunk/doc/ install_script.sh" is a work around. Personally, I find this preferable, since I really hope I'm not reinstalling so often that I need to update the script regularly. The second bump in the road was when it went to build zlib, since that was the default. I'm not sure that the tried to download the packages, but the URL http://yt.enzotools.org/dependencies/ zlib-1.2.3.tar.bz2 throws a 404. Setting YT_DIR=/share/home/00336/rwagner/yt-x86_64/src/yt-trunk-svn/ tar: zlib-1.2.3.tar.bz2: Cannot open: No such file or directory tar: Error is not recoverable: exiting now tar: Child returned status 2 tar: Error exit delayed from previous errors Installing ZLIB ./install_script.sh: line 121: cd: zlib-1.2.3: No such file or directory Failure. Check /share/home/00336/rwagner/yt-x86_64/yt_install.log. This was fixed by setting INST_ZLIB=0. Again, not a big deal. Other than these items, the install went perfectly, and all of the installed packages seem to be working fine. --Rick
