We're currently pulling gnulib's errno module as a dependency of some other module. That provides an errno.h that defines EILSEQ to a distinct value if the system's errno.h doesn't define it already. However, GNU iconv does this: /* Get errno declaration and values. */ #include <errno.h> /* Some systems, like SunOS 4, don't have EILSEQ. Some systems, like BSD/OS, have EILSEQ in a different header. On these systems, define EILSEQ ourselves. */ #ifndef EILSEQ #define EILSEQ @EILSEQ@ #endif That's in: http://git.savannah.gnu.org/cgit/libiconv.git/tree/include/iconv.h.in The "different header" mentioned is wchar.h. This is handled in: http://git.savannah.gnu.org/cgit/libiconv.git/tree/m4/eilseq.m4 which defines @EILSEQ@ to ENOENT if EILSEQ isn't found in either errno.h or wchar.h. So if iconv sets errno to EILSEQ on such system's, it's really setting it to ENOENT. And when we check for EILSEQ, we're checking for gnulib's value. The result is we won't detect the error correctly. As we dropped support for both SunOS 4 or old BSD/OS, maybe we don't need to care about the wchar.h issue anymore. Still, AFAICS, gnulib's m4/errno_h.m4 doesn't know that EILSEQ may be defined in wchar.h, and so on such systems, ISTM gnulib ends up defining an incompatible EILSEQ itself, but I think that should be fixed on the gnulib side, by making it extract the EILSEQ value out of the system's wchar.h, like GNU iconv does. So that leaves handling the case of gnulib making up a EILSEQ value, which we take as meaning the system really doesn't really define it, which will be the same systems GNU iconv sets errno to ENOENT instead of EILSEQ. Looking at glibc's iconv it seems that ENOENT is never used there. It seems it's safe to always treat ENOENT the same as EILSEQ. The current EILSEQ definition under PHONY_ICONV is obviously stale as gnulib garantees there's always a EILSEQ defined. Tested on x86_64 Fedora 20. gdb/ 2014-11-14 Pedro Alves <palves@redhat.com> * charset.c [PHONY_ICONV && !EILSEQ] (EILSEQ): Don't define. [!PHONY_ICONV] (gdb_iconv): New function. [!PHONY_ICONV] (iconv): Redefine to gdb_iconv. |

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.
