Hi List:

I just got a small suggestion to the setup.exe of cygwin. I feel it could
be useful to add a function, which makes it possible to export the package
list (that you currently installed or going to install) into a file (txt for
example), or at least allow people to copy the characters from setup.exe.
This will make a person easily set up a cygwin environment that exactly the
same as someone else who shares his package list. You know when developing
programs, sometimes it is important to have the same version of compilers or
tools. And this could also help to specify which "version" of cygwin you are
using.


I think what you're looking for is '/etc/setup/installed.db' or the output
of 'cygcheck -c[d]'

I've wondered about this too... So if I have changed my Cygwin setup on one 
machine and I want to duplicate those changes on another machine, all I have 
to do is copy installed.db to the other machine and run setup.exe there?

[想 李]

Thanks Larry, good to know "cygcheck" command and install.db.
Sorry that I should have take a look at FAQ more carefully since
all of above have been talked there.

But what I suggested on the other hand is the same as Michael's idea.
I would like to see if cygwin's setup.exe could somehow "import" an
install.db file and perform setup automatically to copy a cygwin
environment with all of your preferred packages. 

This will make life easier without manually choose those packages
one by one from such a long list. You know, I always want to save my
hard disk but always forget something and have to run setup.exe
again and again. This will also give great ease when you transfer your
work from different computers, or when telling your colleague to
create the same cygwin env as yours.

Or, maybe this function also has been implemented by some cygwin
commands else? Please let me know if it exists. Thanks.

Putting "/etc/setup/installed.db" in place before running 'setup.exe'
should make it think all those packages are installed.  Switching to
"Reinstall" for "All" should make it reinstall the packages at the
version specified, if those exists.  This does presuppose that you
have a local package directory with all the packages/versions you
want and that you've told 'setup.exe' to install from that local
package directory.

FYI, I haven't tested this process myself.  Bumps and bruises may
occur. ;-)

That makes sense, thanks.


This does presuppose that you
have a local package directory with all the packages/versions you
want and that you've told 'setup.exe' to install from that local
package directory.


Why is that? If I'm set up to install from the Internet wouldn't reinstall 
all go there? I've never kept a local package directory...

That would replicate the installed packages, but not the versions, since
setup would, by default, pull in the latest. The usual way is to edit
installed.db on the new machine to change all the versions to 0.0,
otherwise setup would think that they are already installed and won't
bother installing them.  You might be able to select "Reinstall" with the
unmodified installed.db, but I haven't tested this hypothesis...

Because the versions you had on your old machine may no longer be
available on Cygwin mirrors.

If you want to replicate the packages, but not the versions, installing
from the Internet is fine (again, change all versions to 0.0 if you want
that, to make sure setup picks up the packages).

That is what I would usually want to do, so editing installed.db and 
installing from the internet is the way to go for me.

Thanks...
