We don't know what packages you've installed, so can't say if this is a
problem with your installation or a more general one. Please read and
follow the Cygwin problem reporting guidelines at
<http://cygwin.com/problems.html>, particularly the part about attaching
the output of "cygcheck -svr" (as an uncompressed text *attachment*).

What makes you believe that? The contents of the libjpeg62 is a single
DLL, /usr/bin/cygjpeg-62.dll (which, BTW, is a compatibility DLL -- you
should be installing libjpeg6b for a more current one). However, if you
select the right packages, libjpeg6b should be selected automatically for
you.

It's not a lib, it's an include file. But yes, it's supposed to be under
/usr/include once you've installed the right packages.

Because you're reinstalling the wrong library. Try "cygcheck -l
libjpeg62" to see the contents of that package on your system.

I doubt that setup "forgets" to install any package that was selected by
the user. Try searching for the file you need on the Cygwin package
search page at <http://cygwin.com/packages/>, and then install that
package using setup.

Plenty to learn, then... :-)
