[Help-gsl] GSL in RTAI-3.2 (kernel module)

[Stefan Lænner]

Hello!

 

I’m currently working on a realtime control algorithm implemented under
RTAI-3.2. For this purpose I would like to use functionalities in Gnu
Scientific Library. The error occurs when the control algorithm is compiled
as a kernel module. Here’s a cut-out of the errors from the compilation:

Does anyone know if it is possible to use GSL in a kernel module??

 

Is GSL a “user space library” which makes usage of types defined in
/usr/include/sys/types.h, and thereby conflicting with the types used when
compiling a kernel module defined in /usr/src/linux/include/linux/types.h? 

 

 

Best regards
