Thank you. I didn't read the readme, but I did read the sources. As far as I understand it, it simply can use the -T option to add a list of additional files from a wrapper. Reini suggest to add the dll to the same address of the shadowed packages. If I read the sources right, that is not even necessary, as it bases all files in an incremental way. I am currently working on it.

Cygwin + Python: unable to remap
Hello, I knew in advance this would be one of the difficult points. I compiled python and ncurses on a prefix. Now I get the following error: 2 [main] python2.6 1180 P:\cygwin\home\prefix\gentoo\usr\bin\python2.6.exe: *** fatal error - unable to remap P:\cygwin\home\prefix\gentoo\usr\bin\cygncurses5.dll to same address as parent: 0x27 != 0x35 I tried to do rebaseall twice, but it doesn't solve it. I can find postings on the web, where some related issues origin from pythons caching mechanisms. Does this rather look like a python or a cygwin issue? Any ideas how to solve it?
