The current system maintains a list of target errno constants in the nltvals.def file, then runs a build-time tool to turn that into a C file. This list of errno values is the same for all arches, so we don't need the arch-specific flexibility. Further, these are only for newlib/libgloss environments, which makes it confusing to support other userland runtimes (like Linux). Let's simplify to make this easier to understand & build. We don't namespace the variables yet, but sets up the framework for it. Create a new target-newlib-errno.c template file. The template file is hand written, but the inline map is still automatically generated. This allows us to move it to the common set of objects so it's only built once in a multi-target build. Now we can remove the output from the gentmap build-time tool since it's checked into the tree. Then we stop including the errno lists in nltvals.def since nothing uses it.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
