            Bug ID: 26136
           Summary: when make it shows "make: *** No rule to make target
                    '../alloc.c'. Stop"
           Product: gdb
           Version: 9.2
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: build
          Assignee: unassigned at sourceware dot org
          Reporter: hyc6643 at 126 dot com
  Target Milestone: ---

Command as below:
 cd gdb/gdbserver
 mkdir buid
 cd build
 ./configure --target=arm-poky-linux-gnueabi --host=arm-poky-linux-gnueabi
 make

it show the message as summary.

Solution:
 add correct path to gdb/gdbserver/Makefile.in line 583
 from 'alloc-ipa.o: ../alloc.c' to 'alloc-ipa.o: ../../alloc.c'

But ../alloc.c is correct, since the full path is gdb/alloc.c.

The commands don't make sense.  Apart from the "buid" / "build" typo, you seem
to be running ./configure in an empty directory, which doesn't make sense.

But it sounds like you are running gdbserver's configure script directly.  You
need to run the top-level configure so that the whole tree is built.

If needed, you can pass --disable-binutils, --disable-gas, etc, to skip
building the other tools.

my fault, my steps are

 cd gdb/gdbserver
 mkdir buid
 cd build
 ../configure --target=arm-poky-linux-gnueabi --host=arm-poky-linux-gnueabi
 make

Wait, which version of GDB are you running?  The gdbserver directory has been
moved to the top-level in GDB 9 I think.  Before that, it was fine to run
gdbserver's configure directly.  After that, you must run the top-level
configure.

Anyhow, if this a problem that applies to an old version, we'll mark the bug as
obsolete.  So please let us know the version of GDB you are compiling.

As suggested to build the gdbserver in the gdb/gdbserver/README:

% mkdir obj
% cd obj
% path-to-gdbserver-sources/configure
% make


after first three commands the Makefile will be generated in the obj folder,
its fullpath is:

gdb/gdbserver/obj/Makefiile

but the fullpath of alloc.c is:

gdb/alloc.c


so if the Makefile wants to use the alloc.c, it needs to check two top levels
of the directory:

../../alloc.c

Ok sorry, so it is only in master (and therefore in the upcoming GDB 10) that
the gdbserver directory was moved, and build instructions have changed.  Still,
these instructions are the "old" way.  So I'd say, try building from master, if
you still encounter some issues there, we can patch it.

1.5 years without a reply, plus I think the new approach works.
