This is a redesign of the root and parent interfaces to eliminate blocking RPC calls. - New session representation at the parent (base/session_state.h) - base-internal root proxy mechanism as migration path - Redesign of base/service.h - Removes ancient 'Connection::KEEP_OPEN' feature - Interface change of 'Child', 'Child_policy', 'Slave', 'Slave_policy' - New 'Slave::Connection' - Changed child-construction procedure to be compatible with the non-blocking parent interface and to be easier to use - The child's initial LOG session, its binary ROM session, and the linker ROM session have become part of the child's envirenment. - Session upgrading must now be performed via 'env.upgrade' instead of performing a sole RPC call the parent. To make RAM upgrades easier, the 'Connection' provides a new 'upgrade_ram' method. Issue #2120
This directory contains ports of popular 3rd-party software to Genode. Usage ----- The tool './tool/ports/prepare_port' in the toplevel directory automates the task of downloading and preparing the library source codes. You can select individual packages that have to be prepared by specifying their base names (without the version number) as command-line argument. For example, the following command prepares both the C library and the Freetype library: ! ./tool/ports/prepare_port libc freetype To compile and link against 3rd-party libraries of the 'libports' repository, you have to include the repository into the build process by appending it to the 'REPOSITORIES' declaration of your '<build-dir>/etc/build.conf' file. Under the hood -------------- For each library, there is a file contained in the 'libports/ports/' subdirectory. The file is named after the library and contains the library-specific rules for downloading the source code and installing header files. How does 'libports' relate to the other repositories? ----------------------------------------------------- Most libraries hosted in the 'libports' repository expect a complete C library, which is provided with the 'libc' package. Please do not forget to prepare the libc package when using any of the other libports packages. The libc, in turn, depends on the 'os' repository for its back end. Because the 'os' repository is the home of the dynamic linker, libraries contained in 'libports' are safe to assume the presence of the dynamic linker and, thus, should be built as shared libraries.
