Subject: Re: [OMPI devel] Session directories in $HOME?
From: Ralph H Castain (rhc_at_[hidden])
Date: 2008-03-31 16:10:05


Here is the problem - the following code was changed in session_dir.c:

-#ifdef __WINDOWS__
-#define OMPI_DEFAULT_TMPDIR "C:\\TEMP"
-#else
-#define OMPI_DEFAULT_TMPDIR "/tmp"
-#endif
-
 #define OMPI_PRINTF_FIX_STRING(a) ((NULL == a) ? "(null)" : a)

- prefix = strdup(getenv("TMPDIR"));

- }
- else { /* ow. just use the default tmp directory */
- prefix = strdup(OMPI_DEFAULT_TMPDIR);
+ else { /* General Environment var */
+ prefix = strdup(opal_tmp_directory());
     }

I believe the problem is that opal_tmp_directory doesn't have
OMPI_DEFAULT_TMPDIR - it just defaults to $HOME.

This should probably be fixed.
