[yt-users] Csh environment setting bug

[Alice Coucke]

Hi Britton,

Thanks a lot for answering me. I asked and my computer came with Lion ... I do not really understand why these issues occurred but anyway yt works perfectly until now !

Best regards,

Alice

Hi Alice,

First of all, welcome to yt!

Someone is looking into your csh issues and will reply to the list with an update soon.

I recently installed yt on a machine running OSX Lion and did not have the issues you reported with zlib and compilers.  My experience was with a brand new machine that did not have previously installed compilers or libraries.  In your case, was this a clean install like mine, or did you upgrade to Lion from an older OS?  If it is the latter, my suspicion is that your issues were related to having some outdated libraries in your path.  I think, in general, setting the environment variable "export CC=gcc" on Lion will minimally do no harm, so we will add a note on that to the install script.

Hello everyone,

It looks like there is a bug with the csh environment setting. I am a Unix beginner so I might have done an error.
I had to make these modifications to the install script to set up yt in a csh shell OSX Lion machine :

* Disable the install of zlib. The HDF5 build failed because of some sort of version confusion.

* Force the use of gcc over the newer clang compiler by setting :
export CC=gcc
at the top of the install script. Matplotlib-1.1.0 fails to compile with the default Lion cc which is clang based.

Once installed, I had difficulties to run it. I tried to follow the Extremely Simple Data Inspection.


$ yt stats $YT_DEST/src/yt-hg/tests/DD0010/moving7_0010


BUT that is what happens :


yt : [ERROR    ] 2012-03-23 11:17:08,651 Couldn't figure out output type for /Users/acoucke/yt-i386:/src/yt-hg/tests/DD0010/moving7_0010

    retval = self.onecmd(argv)

  File "/Users/acoucke/yt-i386/src/yt-hg/yt/utilities/command_line.py", line 44, in _fix_pf
    raise IOError
IOError


Then if I type :


$ echo $YT_DEST

/Users/acoucke/yt-i386:


It seems that there is an unexpected colon here because :


$ ls /Users/acoucke/yt-i386:
ls: /Users/acoucke/yt-i386:: No such file or directory


I have to use :


setenv YT_DEST /Users/acoucke/yt-i386




to make that works.







Best,
