Python Image Library (PIL) build error on Cygwin

[Steve Holden]

Does anyone know the workaround for this error, encountered when trying
to build PIL 1.1.4 from source under cygwin (Python 2.3.3)?

Erk. I *hate* having to mess around with stuff like this.

Rebasing your system should fix the problem. See the following:

Yup, now I can't find the Tk library, but the load errors are gone and
the rest is fixable. This all seems very esoteric, I'm glad it's going
away ...

Does the following from the Cygwin Python README help?

4. _tkinter users should note that Cygwin tcltk is really a Win32
package and hence, does *not* understand Cygwin style paths. To use
the _tkinter module you must define the following environment
variables:

$ export TCL_LIBRARY=$(cygpath -w /usr/share/tcl$version)
$ export TK_LIBRARY=$(cygpath -w /usr/share/tk$version)

Unfortunately that doesn't seem to help:

I'm wondering if I might need to download extra libraries, but I can't
see anything appropriate.

Try

cd /usr/lib
ln -s libtk84.a libtk8.4.a
ln -s libtcl84.a libtcl8.4.aHTHNorman
