This patch removes the component_entry_point library, which used to proved a hook for the libc to intercept the call of the 'Component::construct' function. The mechansim has several shortcomings (see the discussion in the associated issue) and was complex. So we eventually discarded the approach in favor of the explicit handling of the startup. A regular Genode component provides a 'Component::construct' function, which is determined by the dynamic linker via a symbol lookup. For the time being, the dynamic linker falls back to looking up a 'main' function if no 'Component::construct' function could be found. The libc provides an implementation of 'Component::construct', which sets up the libc's task handling and finally call the function 'Libc::Component::construct' from the context of the appllication task. This function is expected to be provided by the libc-using application. Consequently, Genode components that use the libc have to implement the 'Libc::Component::construct' function. The new 'posix' library provides an implementation of 'Libc::Component::construct' that calls a main function. Hence, POSIX programs that merely use the POSIX API merely have to add 'posix' to the 'LIBS' declaration in their 'target.mk' file. Their execution starts at 'main'. Issue #2199
File terminal is a service that provides a terminal-session interface and redirects the terminal input and output to a file. ! <config> ! <policy label_prefix="client1" filename="test.txt" /> ! <policy label_prefix="client2" filename="file.dat" io_buffer_size="4K"/>h ! <libc stdout="/dev/log"> ! <vfs> ! <dir name="dev"> <log/> </dir> ! <fs/> ! </vfs> ! </libc> ! </config> To keep things simple, a client can only open one file at the moment.
