Support for "make check" and "make check-install" is + complete, and runs through all the subdirectories here when this + command is issued from the build directory. Please note that + "make check" requires DejaGNU 1.4 or later to be installed. Please + note that "make check-script" calls the script mkcheck, which + requires bash, and which may need the paths to bash adjusted to + work properly, as /bin/bash is assumed. + +Other subdirectories contain variant versions of certain files +that are meant to be copied or linked by the configure script. +Currently these are: + + config/cpu + config/os + config/io + config/locale + +In addition, three subdirectories are convenience libraries: + + libio + Contains the subset of the GNU libio library needed for + C++. Currently not used. + + libmath + Support routines needed for C++ math. Only needed if the + underlying "C" implementation is non-existent, in particular + required or optimal long double, long long, and C99 functionality. + + libsupc++ + Contains the runtime library for C++, including exception + handling and memory allocation and deallocation, RTTI, terminate + handlers, etc. + +Note that glibc also has a bits/ subdirectory. We will either +need to be careful not to collide with names in its bits/ +directory; or rename bits to (e.g.) cppbits/. + +In files throughout the system, lines marked with an "XXX" indicate +a bug or incompletely-implemented feature. Lines marked "XXX MT" +indicate a place that may require attention for multi-thread safety. |
