RTAI with 4.19.152 - Bugs Fixed. Testers Needed

=== Installing RTAI === Commands marked with # specify root, commands marked with $ are user commands. 1.) Download the RTAI source $ git clone https://github.com/NTULINUX/RTAI.git 2.) Patch kernel with IPIPE, in this case we use 4.19.152 # rm -rf /usr/src/000*.patch /usr/src/linux # cd /usr/src # wget https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.19.152.tar.xz # tar xf linux-4.19.152.tar.xz # ln -sfv linux-4.19.152 linux # cp -aLv /path/to/this/RTAI-git-tree/ksrc/patches/v4.19.152/*.patch /usr/src/ # cd linux # patch -p1 < ../0001*.patch # patch -p1 < ../0002*.patch # patch -p1 < ../0003*.patch # patch -p1 < ../0004*.patch # make olddefconfig # make menuconfig Configure to your needs # make bzImage && make modules # make install && make modules_install 3.) Update grub Refer to your distribution documentation to do this. Generally for newer distros: # grub-mkconfig -o /boot/grub/grub.cfg 4.) Configure, build and install RTAI (MUST BE BOOTED INTO YOUR NEW RTAI KERNEL) $ cd ~/RTAI $ ./autogen.sh $ make menuconfig Configure to your needs. You may also use ./configure instead. For a full list of possible options: $ ./configure --help To build and install RTAI: $ make # make install === To create an RTAI .deb package === Remove any previously installed RTAI packages: # apt-get purge linux-*-rtai* rtai-modules* Notice: You must run the command above from inside a directory that does not contain any .deb packages, otherwise you may see errors such as: E: Unable to locate package linux-4.19.152-rtai_4.19.152-rtai-1_amd64.changes $ cd ~/RTAI $ ./autogen.sh $ ./debian/configure 4.19.152 rtai FIXME: In some cases (undetermined as of yet) you may need to use this command instead: $ ./debian/configure 4.19.152 rtai amd64 Now you are ready to build the actual package: $ dpkg-buildpackage -uc -us 5.) LinuxCNC Configure LinuxCNC: $ cd linuxcnc/src $ ./autogen.sh $ ./configure For a full list of possible options: $ ./configure --help Now build LinuxCNC: $ make Allow LinuxCNC to change permissions as needed: # make setuid To test LinuxCNC in a run-in-place environment: $ cd ../ && . ./scripts/rip-environment To run LinuxCNC latency test in said environment: $ latency-test Or to run LinuxCNC itself: $ linuxcnc For more information on building and installing LinuxCNC, please visit: http://linuxcnc.org/docs/master/html/code/building-linuxcnc.html
