Re: 1.5.25: Cygwin, LAPACK, and ssh -- output "swallowed"

Concise problem description:
A C/C++ program that incorporates LAPACK functions "swallows" program output when run (as a command) over an ssh connection.

In all of the following, "hollyberry" is running Cygwin 1.5.25 on XP; "bruno" is running Debian testing (2.6.26-1-amd64 kernel).

Example 1 (swallowed output):

jkramer3@bruno:~$ ssh hollyberry ./testdgtsv.exe
jkramer3@bruno:~$ ssh hollyberry "./testdgtsv.exe"
jkramer3@bruno:~$

No output is printed, which I'm describing as "swallowed".

Example 3 (logging in to the Cygwin machine using ssh (essentially making it a local session) also works):

jkramer3@bruno:~$ ssh hollyberry
Last login: Tue Dec 30 15:56:52 2008 from 192.168.1.4

jkramer3@HOLLYBERRY ~
$ ./testdgtsv.exe
   6.5
  12.0
  15.5
  19.5
  20.5

$ logout

Jim,


This may be an issue with your path. In your example 1, try

ssh hollyberry echo '$PATH'

The LAPACK dll is in /usr/lib/lapack/, so that will need to be in your path.

Hope this helps.
