I have encountered a problem installing Cygwin using a recent setup.exe.
I looked for previous posts about this subject and found a few. However
they did not answer my questions. Following are references to similar posts:
I am attempting to download all cygwin packages locally, but only
install a minimal selection of those packages for the moment. Basically
i want to create a CD with a snapshot of all Cygwin packages from a
point in time.
I previously had a bare bones cygwin install. I re-downloaded setup.exe
from the website (using a recent setup.exe as of early May 2008) as i
couldn't find the old setup.exe i used to perform the previous install.
I then removed any old cache files but not the old C:\cygwin install. I
then executed setup.exe and selected Download but not install, and asked
it to download everything. I came back after work and the download was
Then i re-ran the setup.exe this time I selected install from local
directory and chose a number of packages to install. At various points
during the install i had a message box pop up:
"Can't open (null) for reading: No such file"
After displaying this the install then moves onto the next package. Some
of them seem to install successfully others do not.
I eventually got sick of the message box and aborted the installation
The questions i have are:
1) What is the cause of this "Can't open (null)" message box?
2) Is there any way of salvaging my current package download cache?
I would rather not re-download everything again (though would preferr
this to a labour intensive task) and also would not like to go through
and for each package that fails to install do some manual task to clean up.
3) Is it best that i wipe the existing (now partial) install of cygwin
from my system and try to start from a clean slate?
4) If i have to re-download everything or do this again in the future,
what is the best way to avoid this problem?
Just a side question, Does anyone know how much disk space it takes to
