Below is the table describing environment variable which control configuration of PW32 (i.e. runtime library itself) or used by it to perform API requests.
Note: you may set none variables and still get sane behaviour. However, proper setup is recommended.
| PW32_PREFIX | Directory, where PW32 is installed (POSIX path syntax) |
| ROOT_DRV | Partition (drive) mounted as root (/). You should set this to partition where your $(prefix) is. If you don't set this, current drive will be treated as root, so you'll be ok if you'll keep yourself within single drive. |
| MNT_PNT | Mount point to support Cygwin's way of accessing arbitrary partitions. File on partition <drive> will be accessed as $(MNT_PNT)/<drive>/<path>, e.g. if set MNT_PNT=/cygdrive, /cygdrive/e/dir/file.txt would be "valid" path. Note that such way of accessing other partitions is deprecated. Use /mnt_<drive>/<path> instead. Value of MNT_PNT must begin with '/' and not end with it! Default value '/' will give (deprecated even by Cygwin) syntax //<drive>/<path> . |
| USER | Your login name (takes precedence over LOGNAME) |
| GROUP | Your group name |
| STRACE | Enable strace facility for programs if debugging version
of pw32.dll is active. Syntax: STRACE=<option>:<value>(;<option>:<value>)* Valid options are:
|
| TZ | You should set this to negative of your GMT offset to get local time correctly deduced. E.g. TZ=-02:00 for Europe (GMT+2). Read susv2 for more information. |
| HOME | Path to your home directory. |
| LOGNAME | Your login name |
