Quoting from the exchange between Michael Haberler and Anders Wallin: >> <AW> sudo update-initramfs -c -k 3.2.21-xenomai+ (I am not sure this is >> required or done by dpkg) > > <MAH> at least the 10.04 dpkg fails to do that for me, maybe this is some > option I am missing; but dpkg and friends are in such deplorable shape in > 10.04 that I prefer not to look into the issue - they are too old to even > compile 3.x kernels. >> <AW> sudo update-grub >
In 10.04LTS, the update-initramfs step fails (don't ask me why; as Michael says, dpkg and friends are in deplorable shape in 10.04) and hence the update-grub step fails too because it finds an incomplete set of boot files. Both steps must be done manually after the fact. However, thanks to the stable of virtual machines I keep on standby for just this sort of testing, I can confirm that, performing the same steps with Michael's .deb files in 12.04LTS, dpkg succeeds not only at the update-initramfs step (watch the scrolling messages in the terminal window or look for the resulting file /boot/initrd.img-3.2.21-xenomai+) but also at the update-grub step (again, watch the scrolling messages in the terminal window), so I needed to perform neither step manually in 12.04LTS. >> <AW> By looking at the output of ./configure I installed the following >> packages. >> >I don't know if this set is minimal or optimal, but at least configure and >> >the build seems to complete.

Watch the warnings scroll in the ./configure output. Of course, dpkg-checkbuilddeps will also list these missing packages, but I find it hard to notice a few non-docs-related files in a big list; besides, this approach offers no statement of what requires the missing packages. Obviously, LinuxCNC builds without these libraries; it just won't be able to do the three things I mention. >> FWIW I would consider this rtos work more important for a linuxcnc 2.6 >> >release than the redis work that just seems to break the build and cause >> >problems on 12.04/12.10. Errm. Let's review the bidding here. In a pristine virtual 12.04LTS host, I just built Michael's experimental LinuxCNC 2.5 based on his threads=xenomai-user configuration and his custom kernel. I then rebooted this host to the regular kernel, pulled the latest from the master branch on git.linuxcnc.org, and built a LinuxCNC 2.6.0~pre simulator. Neither build broke. In the first case redis isn't present, as Michael has already explained, but in the second case redis certainly is present. Where in the build are you running into trouble with redis on a 12.04LTS machine? I'd like to be able to contribute to debugging the problem so we can keep the ball moving forward, but I have nothing to go on.
