Thanks so much Florian
I tried altering line 217 from "8.0" to "16.0" and it didn't allow the
make check to pass so I disabled the euler call with a return as
suggested. This allowed the ImathTest to pass. Then I got quite a ways
through IlmImfTest before it failed when trying to open a blank file:
Error -- caught exception: Cannot open image file "imf_test_rgba.exr".
Cannot initialize semaphore (No such file or directory).
assertion "false" failed: file "testRgba.cpp", line 418
Then if i comment this out it still catches on the same issue (no such
file) in a later process. This is with a fresh download of cygwin so if
there is something obvious I'm doing wrong I'm all ears :-)
Thanks

For older versions of Windows we had to disable the code
in testExtractEuler.cpp because it failed for no good reason.
We thought it was a compiler bug, but it could also be a
problem with some library that is used by both Visual C++
and cygwin.
Try changing line 217 in testExtractEuler.cpp from
float eps = 8.0 * limits<float>::epsilon();
to
float eps = 16.0 * limits<float>::epsilon();
If make check still fails, disable the test by putting a return
statement at the beginning of function testExtractEuler(),
at line 240. If make check succeeds after that, you can use
the OpenEXR libraries (they don't use Euler angles). Just don't
call the Euler angle extraction functions in your own code unless
you figure out how to fix them.
