c# programming

Hi, anyone knows anything about the developments with c' programming under windows machines?
O' Reilly had ported the rotor to Linux, but I dont know anyone who has actually compiled it to the end.
I am using a Linux Mandrake box 2.2.17 and gcc v3.1, after many error messages down the line I got this after being able to compile PAL, undefined reference to _fp_hw.

anyone with a clue to this please respond, if there is a better place to ask this question please let me know aswell.

Thank you!
