taskkill - error while loading shared libraries - LD_LIBRARY_PATH?

[Robert Mark]

Hi All,

I have upgraded to Cygwin 1.7 (CYGWIN_NT-5.1 1.7.1(0.218/5/3)
2009-12-07 11:48) and am having trouble running a windows commands
that I use a lot as part of Cygwin. For example, when I use taskkill I
get:

/c/WINDOWS/system32/taskkill.exe: error while loading shared
libraries: ?: cannot open shared object file: No such file or
directory

I have read some posts from this list and seen discussion around
LD_LIBRARY_PATH being the path for DLLs. In my environment the
LD_LIBRARY_PATH variable is not set. I try "export
LD_LIBRARY_PATH="$PATH" but that doesn't fix the issue either.

Any advice as to how I can get this working would be most appreciated!

Rob

Hi All,

No one else has seen this sort of issue before?

Since taskkill is a Windows app and not a Cygwin one, there is no
benefit to fiddling with LD_LIBRARY_PATH, even if Cygwin apps
would otherwise be affected by it (they won't be).  I find the
terminology of the error you see to particularly interesting, since it
doesn't look like your standard Windows error report and certainly
doesn't match the format I see when I force taskkill to error out.
But that's a MS issue/oddity that's better addressed in a Windows
forum.

OK, I now know it has nothing to do with LD_LIBRARY_PATH - instead
it's a cygdrive prefix issue.

Turns out it was my cygdrive mount was not being set properly. I was
changing the cygdrive mount in my own .bash_profile (via "mount
--change-cygdrive-prefix /") because at the time I was not admin of
the computer and couldn't edit /etc/profile or /etc/fstab. It seems
this is too late: by the time my .bash_profile is evaluated, the PATH
(or something else?) had already been set up and the paths are
screwed.

I fixed up the rights on Windows so I am admin now,  /etc/fstab like so:
none / cygdrive binary,posix=0,user 0 0

And now I can execute the Windows commands as usual.

You don't have to run under an admin account.  If the cygdrive prefix
is marked as "user" /etc/fstab, you can override it in your user's
/etc/fstab.d/$USER fstab file.

Actually, the cygdrive prefix is "user" by default if you don't
have an entry in /etc/fstab.
