Crashing PDFs and Login screen after Yt installation
Dear all I have recently tried to install Yt, including Enzo, with the installation script provided in the Yt webpage; setting the Enzo flag=1 and installing as superuser in /usr/local all the files I had the following two problems: 1) the enzo clone was not installed... just before finishing the script said something like Python SSL not found or supported, and the enzo installation was aborted. 2) After all this, I was not able to (a) open any pdf file either with evince or xpdf (under linux; either ubuntu 10.04 and linux mint 13 - running gnome), (b) login .. my "welcome screen" was off, completely gone or black as in my laptop (a toshiba with linux mint). so I could not login! In the case of my desktop at work, I had to reinstall the operating system. Have any of the people of this forum seen this kind of problems? Any ideas what might have gone wrong or how to fix this? cheers, hector
Hi Hector, Sorry to hear you're having trouble. The first issue is an easy fix, you must install the libssl-dev package before running the install script. Your OS issues are troubling and we'd like to make sure that this issue isn't repeated. To figure out exactly what happened, we need to know how you ran the install script. Unfortunately you haven't given us enough information to figure out what went wrong. Please let us know exactly what you did, and if you can, please forward us the install log file for the failed installation. Normally the install script shouldn't be able to write to system directories like /usr/local, but if you ran the script using escalated privileged (e.g. with sudo), it may have overwritten important system files. In general, the install script is not supposed to be run with root privileges. Cheers, Nathan On 7/23/12 12:52 PM, Héctor Aceves Campos wrote:

Hi Nathan and Hector, I'm sorry for your trouble! I suspect that what happened wasn't that yt overwrote any files. I think it only installed new files, but what ended up happening is that Ubuntu searches /usr/local *first*, and then searches the rest of LD_LIBRARY_PATH. So in doing so, it hit an incompatible libpng (which we should update anyway) and which then killed theo ther stuff. I suspect the contents of /usr/local could have been wiped and it would have been okay. I've issues a pull request with some fixes to the install script that will: * Tell you which packages you need to install on Ubuntu * Refuse to install in /usr/local * Refuse to run as sudo I think this should cover these use cases. Again, I'm sorry this caused you any troubles. Hopefully we can work them out! And, thanks for bringing them to our attention. It stinks that this happened, but I think we can try to make sure it doesn't happen again to you or anybody else. -Matt On Mon, Jul 23, 2012 at 7:56 PM, Nathan Goldbaum <nathan12343@gmail.com> wrote:

Hi Nathan and Matt, Thanks for your prompt reply. Yes, I installed it as "sudo" ; since I want it to be available to several users (in particular some grad students). Unfortunately I did it in /usr/local and the $PATH points to /usr/local as a lookup directory first. I guess that the best way -probably under the assumption that Yt and Enzo be available to several people-- is to proceed as follows: a) Install the libssl-dev package b) Install in directory /opt c) Set the appropiate environment flags later... (including PATH=$PATH:/opt..... LD_LIBRARY=/opt/yt.....) I will try it this way in my laptop... before I screw the department's computer! :-) Thanks again, and will let you know about it.

I think that sounds good -- note also that the install script comes with an "activate" script which will set these variables for you, and that way you can enter/exit the yt environment at will. Let us know if this doesn't work, and good luck! Matt

Hi Nathan and Matthew I was able to solve the difficulties with the installation of Yt+Enzo by reinstalling everything in a /home/usr/local directory instead of the /usr/local with root privileges. As I mentioned, in the root partition gave me errors such as not been able to get a login screen etc, (even problems with my wireless connection!!); so I decided to put everything in my HOME directory. More over, it is quite convenient here if new problems are added; as one David Collins helped us (several students and me) at the National Observatory of Mexico. Although not the right forum here, I just want to let the Yt and Enzo community that a postdoctoral position in astrophysics is open at the National University of Mexico ...here is the link: * http://www.astroscu.unam.mx/IA/images/PostdoctoralpositionAstrophysics.pdf* just in case some one is interested..... well, thanks for all your help .. hector On Mon, Jul 23, 2012 at 6:56 PM, Matthew Turk <matthewturk@gmail.com> wrote:
