PTXdist ======= Installation ------------ To install PTXdist, just run ./configure --prefix to configure the packet (FIXME: make this --prefix=/path..., probably by really autoconfigurizing), then make to build everything and make install in case you want to install it. Make sure your $PATH environment variable points to /bin, because that's where the ptxdist frontend program is being installed to. For developers who want to work with svn versions of PTXdist it is only necessary to run "./configure && make" and set the PATH variable to the bin/ directory inside the PTXdist tree. Quickstart ---------- For the impatient: try out to compile your own Linux system for generic i586 and above machines by cloning the generic-i586-glibc project: somewhere$ ptxdist clone generic-i586-glibc myproject This copies the generic-i586-glibc project into ./myproject, which is your "workspace" for the following actions. Change into your project's workspace and build everything: somewhere$ cd myproject somewhere/myproject$ ptxdist go This builds a root filesystem into the root/ directory of your workspace. You can try it with somewhere/myproject$ chroot root/ /bin/sh If you have more time to find out how it works, read on. Idea ---- PTXdist is a tool which can be used to generate a root tree for all kinds of Linux systems. It was written with embedded systems in mind, but there is no reason why you can't use it to configure your firewall, router or whatever dedicated "device" comes to your mind. The job works like this: you run 'ptxdist menuconfig', configure what you need and get a .config file. Run 'ptxdist go' and you'll find a root tree in root/. Voila. Directory Layout ---------------- These files and directories are supposed to be in an empty project directory: kernel-patches-native/ contains patch series for the kernel which is compiled natively (for simulation) kernel-patches-target/ contains patch series for the target kernel kernelconfig.native kernel .config file for the native kernel kernelconfig.target kernel .config file for the target kernel patches/ project specific patches, overwrites the generic ones from PTXdist projectroot/ put files here which are to be copied over to the target's root directory, like for example etc files, scripts, ... Note that the copying has to be done explicitly by some project specific rule file. ptxconfig .config file to configure the userland for your project. rules/ contains project specific rules src -> ... link to point to your directory containing tarball files for the packets. Additionally some other directories are being built when you run "ptxdist go" or other start other build targets. build-host/ build directory for host tools build-cross/ build directory for cross tools build-target/ build directory for target tools images/ 'ptxdist images' creates tarballs and filesystem images in this directory. local/ tools which are installed locally go to this dir root/ root filesystem for the target state/ state files (show in which state packages currently are during the compilation) For more details look at the output of 'ptxdist --help' or see the PTXdist manual.
