Hi,
I ported a database application on Windows 2000 using cygwin. For testing reasons I put on a clean (no cygwin installed) Windows 2000 machine the generated app.exe and the cygwin1.dll. For some reason the dbopen() call failed when trying to read the created before database.
After trying to investigating the problem, I found out that it is working if in the registry the following data exists:
HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin\mounts v2
cygdrive flags 22
If this is missing the dbopen() call will fail.
My question is: Because at one point I would like to distribute the product to others also, and I don't want to obligate them to install the cygwin, I would like to know why this string is required, and if my only solution would be to add that key in the registry if the cygwin is not already installed on that machine?
Attempting to hide your application's dependence on Cygwin is not a good idea. We have a steady stream (well, a trickle, anyway) of people who install Cygwin and immediately have problems because unbeknownst to them, something they installed earlier (sometimes a long time ago) included a Cygwin1.dll and multiple Cygwin DLLs on a given system don't coexist well.
I'm no lawyer, but be aware of your obligations under the open source license under which Cygwin is made available (whatever they are).
Thanks a lot, viv
