I saw this on PPC64 once: not installed on target (gdb) PASS: gdb.trace/actions.exp: 5.10a: verify teval actions set for two tracepoints break main Breakpoint 4 at 0x10000c6c: file ../../../src/gdb/testsuite/gdb.trace/actions.c, line 139. (gdb) PASS: gdb.trace/actions.exp: break main run Starting program: /home/palves/gdb/build/gdb/testsuite/outputs/gdb.trace/actions/actions tstatus Breakpoint 4, main (argc=1, argv=0x3fffffffebb8, envp=0x3fffffffebc8) at ../../../src/gdb/testsuite/gdb.trace/actions.c:139 139 begin (); (gdb) tstatus Trace can not be run on this target. (gdb) actions 1 Enter actions for tracepoint 1, one per line. End with a line saying just "end". >collect $regs >end (gdb) PASS: gdb.trace/actions.exp: set actions for first tracepoint tstart You can't do that when your target is `native' (gdb) FAIL: gdb.trace/actions.exp: tstart info tracepoints 1 Num Type Disp Enb Address What 1 tracepoint keep y 0x00000000100007c8 in gdb_c_test at ../../../src/gdb/testsuite/gdb.trace/actions.c:74 collect $regs not installed on target ... followed by a cascade of FAILs. The "tstatus" was supposed to detect that this target (native) can't do tracepoints, but, alas, it didn't. That detection failed because 'gdb_test "break main"' doesn't expect anything, and then the output was slow enough that 'gdb_test "" "Breakpoint .*"' matched the output of "break main"... The fix is to use gdb_breakpoint instead. Also check the result of gdb_test while at it. Tested on x86-64 Fedora 20, native and gdbserver. gdb/testsuite/ChangeLog: 2015-04-07 Pedro Alves <palves@redhat.com> * gdb.trace/actions.exp: Use gdb_breakpoint instead of gdb_test that doesn't expect anything. Return early if running to main fails.
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.
