Hello ! Up to now it had never been a problem using some maths in RT space. I alwas just linked libm.a statical to my kernel mod and that was it. Since I don't use very komplex math, only sine, cosine, exp, arc* I never made a fuss about it. My glibc version 2.1.3 now wnats to do a standard error output for some functions where a reange check is performed (like asin). Now I am in big trouble since insmod cries for unresolved function, fputs and stderr. My question is: Has anybody found out how to turn the default output to stderr from libm of ?? I really don't need this facillity since I avery carefully check all operands before calling this function ! blue skies Jan Albiez -- -- Jan Christian Albiez -- -- FZI -- Haid-und-Neu-Str. 10-14 -- 76131 Karlsruhe -- +49 721 9654 206 -- -- segmentation violation in module reality.o ... ... please shutdown your universe and reboot -- ----- End of forwarded message from [EMAIL PROTECTED] ----- -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] -- For more information on Real-Time Linux see: http://www.rtlinux.org/rtlinux/
