Disable gdb Python support?

Disable gdb Python support?

[Grant Edwards]

We've been using crosstool-ng for a couple years -- we're currently
using 1.12.  Gdb used to work find for us, but it seems to have broken
when we switched our configuration from 6.8 to 7.2. It appears that
newer versions of gdb are being built with some sort of Python
dependency:

ldd ./arm-linux-gdb
        linux-gate.so.1 (0xffffe000)
        libncurses.so.5 => /lib/libncurses.so.5 (0xb7743000)
        libz.so.1 => /lib/libz.so.1 (0xb772e000)
        libm.so.6 => /lib/libm.so.6 (0xb7707000)
        libpthread.so.0 => /lib/libpthread.so.0 (0xb76ee000)
        libdl.so.2 => /lib/libdl.so.2 (0xb76e9000)
        libutil.so.1 => /lib/libutil.so.1 (0xb76e5000)
>>>>    libpython2.6.so.1.0 => /usr/lib/libpython2.6.so.1.0 (0xb758a000)
        libexpat.so.1 => /usr/lib/libexpat.so.1 (0xb7560000)
        libc.so.6 => /lib/libc.so.6 (0xb7410000)

That's causing problems for us since not all of our host machines have
the same python versions installed.

We didn't seem to have this problem with gdb 6.8.

Is there any way to disable the Python support when crosstool-ng
builds the host-side gdb?

Yes, in the menuconfig:
  Debug facilities  --->
  [*] gdb  --->
      [ ] Enable python scripting

Hmm.  That must be something added since 1.12. It doesn't show up in
my .config file nor when when I do ./ct-ng menuconfig.

I tried a couple more recent versions, but my build scripts failed at
the "./configure --local" stage, and I haven't had time to figure out
how I need to change my build scripts and documenation.

It's probably time to figure out the current spelling for "./configure
--local"...

Nope, it probably isn't in ct-ng 1.12; it's been added after that.
In 1.12, the python dependencies was not caught, so there was no
provision against it sneaking in.

Note that 1.12.x is no longer maintained. The current maintained series
is the 1.16.x. Please upgrade.

Since switching to autoconf, the switch was renamed --enable-local. With
autoconf, it;s notpossible (AFAIK) todefine custom switches, besides the
--with-XX or --enable-XXX forms, hence the --enable-local.

Ah!  I had started looking through changelogs, but hadn't found that
yet.  I just tweaked by build script and am now building using ct-ng
1.16 with gdb's python support disabled.

Thanks!
