Reporting problem requiring rebaseall to solve it.

Reporting problem requiring rebaseall to solve it.

[Daniel Povey]

Reporting problem and solution, but I would appreciate if cygwin
experts could comment on the underlying reasons why this kind of thing
happens and why rebaseall is needed.

I have done a pretty clean install of the latest Cygwin and want to
report a problem (and solution) so people will be able to fix it
themselves.  I am installing on a domain-joined Win7 machine.  My
installation process is to run setup.exe, only choose wget as an extra
package, and then use the apt-cyg script to install extra packages, as
in:
cp apt-cyg /bin
apt-cyg install `cat packages`
where "packages" is a list of the packages I had from a previous install.
When I try to start X, it fails and I get the following errors in
/var/log/XWin.0.log (see bottom of email).l

I was able to fix this problem by doing "rebaseall" [i.e.: close all
cygwin processes, go to "cmd", cd to c:\cygwin\bin,
and type "ash rebaseall".   This gives the following errors which I am
ignoring for the time being:

C:\cygwin\bin>ash rebaseall

/usr/lib/engines/libaep.so: skipped because not writable

The errors in XWin.0.log are below, for search purposes.

FWIW, you don't need to use apt-cyg to automate an install of a certain
set of packages.  Using the '-P' parameter of 'setup.exe' to list out the
packages you want to install will work.

If you're looking for a basic overview of why rebasing is necessary in
some cases, you should read /usr/share/doc/Cygwin/rebase*.README.  This
summarizes things quite well.  If you're looking for more details, the
email archives (cygwin-apps) has allot of discussion about it in the
history.  It's a ways back though. ;-)
