This patch decouples the kernel-specific implementation of the dynamic linker from its kernel-agnostic binary interface. The name of the kernel-specific dynamic linker binary now corresponds to the kernel, e.g., 'ld-linux.lib.so' or 'ld-nova.lib.so'. Applications are no longer linked directly against a concrete instance of the dynamic linker but against a shallow stub called 'ld.lib.so'. This stub contains nothing but the symbols provided by the dynamic linker. It thereby represents the Genode ABI. At system-integration time, the kernel-specific run/boot_dir back ends integrate the matching the kernel-specific variant of the dynamic linker as 'ld.lib.so' into the boot image. The ABI symbol file for the dynamic linker is located at 'base/lib/symbols/ld'. It contains the joint ABI of all supported architectures. The new utility 'tool/abi_symbols' eases the creation of such an ABI symbol file for a given shared library. Its result should be manually inspected and edited as needed. The patch removes the 'syscall' library from 'base_libs.mk' to avoid polluting the kernel-agnostic ABI with kernel-specific interfaces. Issue #2190 Issue #2195
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.
