Linux GDB compilation problem

Linux GDB compilation problem

[Pierre Muller]

    I have a trouble to compile gdb on my new linux box.

   I have the sources on a subdir of

    /data dir that is a mount of a fat32 partition
(used with cygwin in binmode, so that there are no
lineend problems)

   Trying to compile GDB for linux in a subdir of my /home dir
that is a mount of another partition,
   I can successfully configure
but running "make all-gdb" ends with the following error :
  A mv command fails because it tries to move a file
from my compilation dir into a subdir of the sourcedir.

    Shouldn't it be possible to confugre and make even if
the source is on another mount or even only read-only
(on a cd-rom or owner by someone else ?)

    I don't think that its normal that
the make process change the source dir !

   The precise location where this happens is in
   [all-opcodes]
     [1] [all-recursive-am]
     [2] [all-recurvise]
     [3] [POTFILES.in]
     [4] [po/POTFILES.in]

Can't build binutils with read-only source; Was: Linux GDB compilation problem

[Andrew Cagney]

The below was sent to GDB@

As far as i can tell the analysis is correct.  A simple build shouldn't 
be trying to modify files in the ``read only'' src/opcodes tree.

enjoy,
Andrew

Re: Can't build binutils with read-only source; Was: Linux GDB compilation problem

Hi Pierre,

  Your message has been forwarded to the binutils mailing list, since
  the opcodes library is officially part of that project.

  You are correct however, a simple build of the opcodes library, as
  part of GDB or for any other reason, should not try to modify the
  source directory.

  Can you provide some more information please ?  Which version of the
  binutils sources are you using.  (If you build the objdump
  disassembler program and run "objdump --version", this should tell
  you).  What file was the build process trying to move into the
  source directory ?

  The all-recursive-am target is for the automatic rebuilding of the
  Makefile.  In this case it would appear that make is trying to
  rebuild the Makefile.in or config.h files in the source directory.
  This would indicate that the timestamps on your Makefile.am or
  config.in files are wrong (or you have edited them).

Cheers
