Re: [Machinekit] Re: MachineKit build error on debian stretch

gcc-6.3.0 has MUCH stricter type checking etc and throws up many such warnings. It also threw some errors in 2 of the maths functions, which when you looked at the code, beggared belief that they had ever worked. Those have been fixed. There are a lot of instances in the code where things have been 'gotten away with' for a long time. Passing char* to parameters which are defined as taking const char* and vice versa is a prime example. So long as it builds, don't worry overly. The mesa code in particular is low level C device driver stuff, written outside the project and we are not going to mess with it unnecessarily. ;-) On 19/07/17 15:49, med2...@comcast.net wrote: Ok I have made progress.  make ran to completion but there were some warning from the hal component.
