I've been doing some work with chicken and the IUP GUI framework. For the last while, I have been using IUP 3.17. I recently decided to try and get onto the latest version of IUP (3.19.1) and it appears that the IUP developers have changed the name of or removed one of the header files between 3.17 and 3.19.1. The missing file is include/iup_pplot.h. This is causing the iup egg to be unable to build when linked with the new versions of IUP. I'm hoping that the developer of the iup egg is on the list and can maybe take a look. The egg has been wonderfully useful to me and I really appreciate all the work that went into it.
Thanks,
Jeff
