The specific problem I have is this: I have an old (but up-to-date) Cygwin 32-bit installation that has evolved over the past ten years or so. I want to move to a 64-bit Cygwin, with the same facilities.
While the Cygwin graphical installer is moderately nice, it is not "transportable" (Ie you can't copy-and-paste the lines in its windows). So what I'm looking for is this:
- A way to extract a list of currently-installed packages from Cygwin
- A command-line method to say to the installer "Please install this list"
Is this possible? I know I could do it by adding packages ad-hoc, as I find I need them, but this usually happens according to Murphy's Law; that is, either when I'm in a hurry, or don't have an Internet connection, or both.
2Please be aware that not all 32-bit packages are available in the 64-bit version ... – DavidPostill – 2014-12-13T08:09:21.370
@DavidPostill : Yes, thank you, I knew that but it's good to have it recorded here. – Brent.Longborough – 2014-12-13T08:16:11.247
I can't think of an easy way to do this. You might get a better response from the cygwin mailing list where most of the cygwin experts and developers hang out ...
