When the error is text, simply cut and paste the text. Please no private mails. Second the xeno-test you are running is not xenomai 2.6.1 xeno-test, so you have binaries of some other version of xenomai version installed, presumably xenomai 2.5. As explained in the troubleshooting guide, this is a risky situation. > > Regarding the issue with the examples I already read this post > http://www.xenomai.org/pipermail/xenomai/2012-October/026561.html but I > didn't understand exactly what to do with that ...

Using xenomai supposes that you are a C programmer and as such you should already have seen "unresolved symbols", and that you are familiar with using the common unix tools. > > One last question, what does it mean the negative values on the latency > test?? Are they normal?? Yes, this too is an issue which has been discussed many times on this list. -- Gilles.
