question about cygdrive flags string in the registry (Win 2000)

[Viviana Cotirlea]

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?

Thanks a lot,
viv
