Using GNU Library functions with QNX Momentics   
I have a C project where I would like to use some of the functions from the GNU Library in an embedded system. How might
 I set up QNX Momentics so that I can access the GNU Library functions? 

Thanks

What GNU Library you are talking about?

Re: Using GNU Library functions with QNX Momentics   
The GNU Scientific Library, specifically the functions for creating polynomial fits to data sets. 

https://www.gnu.org/software/gsl/manual/html_node/Multi_002dparameter-fitting.html

The problem I am addressing right now is determining the a,b,c values of a least squares polyfit
y=ax^2+bx+c  

for a set of ten x and y data points. This is part of a control loop running at 1000 Hz, so the computation needs to be 
done pretty quickly.

First you need to compile this library for qnx, or find if somebody else 
ported it already.
Then you just follow standard docs on how to include library in your 
build system

Re: Using GNU Library functions with QNX Momentics   
I wasn't able to find one already ported but I can try and compile it myself. 

Thanks
