Yes, I saw it and I have updated my installation. I see the import library now, but my very preliminary tests (test_ada and a simple build) have failed so far:

- test_ada does not produce an executable - see the tarball (sorry, output to the screen is missing, but there was nothing much to see anyway).

- a simple build finds the static library and then the duplicate symbols problem is back.


I guess PLplot needs to be told to use the import library before trying the static one. I have not had time yet to do the manual steps that you suggest.

Not done yet ...
