I use both Windows and cygwin X11 gvim -- mostly the former out of
convenience and speed. I often shell out for filtering, and I'm careful to
ensure that my vimrc shell setting directs commands to cygwin's bash:
let &shell='set HOME=c:\cygwin\home\'.$USERNAME.'&
\ c:\cygwin\bin\bash.exe -i'
However, I recently started to get the following message when sending
expressions to octave:
/usr/bin/octave-3.6.2.exe: error while loading shared libraries: ?:
cannot open shared object file: No such file or directory
I know there there isn't anything *fundamentally* wrong because when I
start up cygwin normally via the mintty shortcut, octave starts fine. I
thought it was a $PATH problem, so I rejigged .bashrc to ensure that the
path is the same regardless of whether I start bash from the mintty
shortcut or shell out from Windows gvim. This does not solve the problem.
I confirmed that $LD_LIBRARY_PATH is empty regardless of how bash is
started up, so I don't think that's the problem.
Can anyone suggest what might be causing the octave error if not $PATH and
$LD_LIBRARY_PATH? Again, there is no problem when invoked from a bash
shell that is started from the mintty shortcut. Furthermore, there was no
problem at all before a few days ago. The only big change is that my admin
deleted Matlab 2012a, but I have Matlab 2013a (in a different path). But
the fact that octave runs from a normally started bash tells me that this
should not be a show stopper (if in fact it's even the cause).
Note that I work in a locked down environment, so I can't upgrade anything
and downloading stuff is hit-and-miss.
