This patch removes possible ambiguities with respect to the naming of kernel-dependent binaries and libraries. It also removes the use of kernel-specific global side effects from the build system. The reach of kernel-specific peculiarities has thereby become limited to the actual users of the respective 'syscall-<kernel>' libraries. Kernel-specific build artifacts are no longer generated at magic places within the build directory (like okl4's includes, or the L4 build directories of L4/Fiasco and Fiasco.OC, or the build directories of various kernels). Instead, such artifacts have been largely moved to the libcache. E.g., the former '<build-dir>/l4/' build directory for the L4 build system resides at '<build-dir>/var/libcache/syscall-foc/build/'. This way, the location is unique to the kernel. Note that various tools are still generated somewhat arbitrarily under '<build-dir>/tool/' as there is no proper formalism for building host tools yet. As the result of this work, it has become possible to use a joint Genode build directory that is usable with all kernels of a given hardware platform. E.g., on x86_32, one can now seamlessly switch between linux, nova, sel4, okl4, fiasco, foc, and pistachio without rebuilding any components except for core, the kernel, the dynamic linker, and the timer driver. At the current stage, such a build directory must still be created manually. A change of the 'create_builddir' tool will follow to make this feature easily available. This patch also simplifies various 'run/boot_dir' plugins by removing the option for an externally hosted kernel. This option remained unused for many years now. Issue #2190 |

This directory contains tools for managing and using the source code of Genode. :'create_builddir' The 'create_builddir' tool provides a convenient way to create build directories for different platforms. Its usage information is printed when starting the tool without arguments. :'builddir/': This directory contains a Makefile template and configuration snippets used by the 'create_builddir' tool. :'tool_chain': This tool downloads, builds, and installs the tool chain needed to build the Genode OS Framework. For getting usage information, start the tool without arguments. :'create_iso': This simple tool helps to build bootable ISO images from your build of Genode. For getting usage information, start the tool without arguments. :'create_grub2': This tool prepares a partitioned disk image with GRUB2 as boot loader. :'grub2-head.img': This file is the head part of a partioned disk image including an installation of GRUB2 as boot loader. GRUB2 is available from http://www.gnu.org/software/grub/ and in major Linux distributions. Steps to reproduce the image creation can be found in 'create_grub2'. :'beautify': Beautify is a coding-style checking tool that analyzes source code for its adherence to Genode's coding style as described in 'doc/coding_style.txt'. Whenever possible, the tool tries to fix the issues and outputs a corrected file. Some corrections, however, require human interaction. In this case, the tool stops the analysis with an error. :'parse_cxx': This tool is a C++ parser used as front-end for Beautify. :'cxx_to_html': This tool converts a C++ source file to a HTML view to be used for the API documentation at the genode.org website. It relies on 'parse_cxx' to do the actual C++ parsing. :'fix_include_ifndef': This tool helps with assigning consistent include guards to header files. :'boot': This directory contains boot-loader files needed to create boot images. :'autopilot': Autopilot is a tool for the automatic execution of run scripts among multiple base platforms.
