I am building rosettaligand for boinc. Compiling linux versions are straightfoward and easy. But when on windows, life is like in the hell. I hacked a few things to get static rosettaligand version built under cygwin on windows7 32bit, and it run smoothly under cygwin emulator. However, when I tried to run rosettaligand from windows commandline prompt, it said "ERROR: Unique best command line context option match not found for -path. Possible matches include: in:path out:path". I changed the line terminator and remove all path seperator in flags file, but the error persisted. What could be the cause of the error?
