My question is about using the NXT Toolbox in simulink. Since there is no built in block for reading the compass sensor, I would like to write an S-function containing C-code with libraries from nxtOSEK (ecrobot_interface.h mainly), which have methods for reading the compass sensor. I have tried using the s-function builder as well as writing the c-file manually from a template, and also the Code Legacy Tool. None of these manages to compile the c-code. I get lots of (>100) syntax errors in library files not written by me, for example:
C:\Matlab\R2012a\targets\nxtOSEK\lejos_nxj\src\nxtvm\javavm\classes.h(70) : error C2143: syntax error : missing ')' before '('
Is there something special I need to think about when using external libraries in C mex S-functions?
