Cross building gdbserver for --host=x86_64-w64-mingw32 with gcc 4.8.4 20141219 (Fedora MinGW 4.8.4-1.fc20), I get: src/gdb/gdbserver/tracepoint.c: In function 'cmd_qtdp': src/gdb/gdbserver/tracepoint.c:2577:7: error: unknown conversion type character 'l' in format [-Werror=format=] trace_debug ("Defined %stracepoint %d at 0x%s, " ^ src/gdb/gdbserver/tracepoint.c:2577:7: error: unknown conversion type character 'l' in format [-Werror=format=] src/gdb/gdbserver/tracepoint.c:2577:7: error: too many arguments for format [-Werror=format-extra-args] src/gdb/gdbserver/tracepoint.c: In function 'stop_tracing': src/gdb/gdbserver/tracepoint.c:3447:7: error: unknown conversion type character 'l' in format [-Werror=format=] trace_debug ("Stopping the trace because " ^ src/gdb/gdbserver/tracepoint.c:3447:7: error: too many arguments for format [-Werror=format-extra-args] src/gdb/gdbserver/tracepoint.c: In function 'collect_data_at_tracepoint': src/gdb/gdbserver/tracepoint.c:4651:3: error: unknown conversion type character 'l' in format [-Werror=format=] trace_debug ("Making new traceframe for tracepoint %d at 0x%s, hit %" PRIu64, ^ src/gdb/gdbserver/tracepoint.c:4651:3: error: too many arguments for format [-Werror=format-extra-args] src/gdb/gdbserver/tracepoint.c: In function 'collect_data_at_step': src/gdb/gdbserver/tracepoint.c:4687:3: error: unknown conversion type character 'l' in format [-Werror=format=] trace_debug ("Making new step traceframe for " ^ trace_debug is a macro that calls: static void trace_vdebug (const char *, ...) ATTRIBUTE_PRINTF (1, 2); The calls that fail checking use PRIu64, etc., like: trace_debug ("Defined %stracepoint %d at 0x%s, " "enabled %d step %" PRIu64 " pass %" PRIu64, tpoint->type == fast_tracepoint ? "fast " : tpoint->type == static_tracepoint ? "static " : "", tpoint->number, paddress (tpoint->address), tpoint->enabled, tpoint->step_count, tpoint->pass_count); gnulib's stdio/printf module replacements may make %llu, etc. work on mingw, instead of the MS-specific %I64u, and thus may make PRIu64 expand to %llu. However, gcc isn't aware of that, because libiberty's ansidecl.h defines ATTRIBUTE_PRINTF as using attribute format(printf). But, with that format, gcc checks for MS-style format strings (%I64u). In order to have gcc expect gnu/standard formats, we need to use gnu_printf format instead. Which version to use (printf/gnu_printf) depends on msvcrt and mingw version, and so gnulib has a configure-time check, and defines _GL_ATTRIBUTE_FORMAT_PRINTF accordingly. Since _GL_ATTRIBUTE_FORMAT_PRINTF is compatible with ATTRIBUTE_PRINTF, the fix is simply to make use of the former. gdb/ChangeLog: 2015-11-17 Pedro Alves <palves@redhat.com> * common/common-defs.h (ATTRIBUTE_PRINTF): Redefine in terms of _GL_ATTRIBUTE_FORMAT_PRINTF after including ansidecl.h. |

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.
