[etherlab-users] Build error in RTW: implicit declaration of function 'xxxxxxxxxxxxx'

[Alex C. Marton]

Dear friends,

I have found the solution to my problem tonight!
It turns out I had set the sample time of my sine wave input 0.001 (the same as 
my model integration step), which is not good! it has to be a continuous signal 
, so the sample time should be 0.
Also, make sure your model doesn't give ANY warnings when you start building it! 
to check this go to your simulink model and select Tools/Simulink Debugger...
Click Play on the upper-left side and see if it says you have any warnings. if 
you do, try to eliminate ALL OF THEM!
Then, the build process will work fine and dandy! 

Thank you for your promp reaction! Wish you all the best!
Alex Marton

Hello!


Thank you for answering! I really need your help on this one.
My linux version is: openSUSE 11.2 "Emerald" - Kernel \r
My RTAI version is 3.7.1
Matlab is R2009b, Simulink version is: v 7.4 and RTW is: v 7.4

Thank you!
Alex
