[Mono-dev] Crash using Crystal Reports on Linux Mono

Joshua,
I'm fairly certain that Crystal Reports will not run on linux, as the managed
DLL's are mostly just wrappers around CR's win32 and COM api's.
This most likely includes both the front end GUI and back end to generate the
reports themselves.
Hence is why we are now using iTextSharp
( http://itextsharp.sourceforge.net/ ) for our reporting needs in our ASP.NET
application (not that it's in the same ballpark, though).
Only the Crystal Enterprise server can run on linux (if you purchase the linux
version).
I hope one day they provide a purely managed version of the apis needed to
connect to CE, then you can do a pure linux solution with asp.net apps at
least.
Cheers!
Curtis.
