FYI: How to build Insight for 64-bit linux with system Tcl et al

[Keith Seitz <keiths at redhat dot com>]

I sent a user these instructions some time ago. Someone was recently
asking on #gdb, so I thought I would publish this to the mailing list.

I am attempting to switch insight to GIT, but no ETA yet.

------

1) Download/checkout gdb 7.6 (or 7.5 or HEAD)
You can find directions for this on gdb's home page. The 7.6 release is
imminent, so I would grab that via CVS (it's easier). You want to check
out the "gdb_7_6-branch":

$ cvs -d:pserver:anoncvs@sourceware.org:/cvs/src login
[enter "anoncvs" as the password]
$ cvs  -d:pserver:anoncvs@sourceware.org:/cvs/src co -r gdb_7_6-branch gdb

2) Install build dependencies
In addition to Insight's build requirements, you will need all of gdb's
build dependencies installed. On Ubuntu 12, I believe you need to grab:

tcl8.5, tk8.5, -dev
itcl3, itk3, -dev
iwidgets4
bison, flex
texinfo
ncurses-dev

You will also need autoconf-2.64 and automake-1.11 to regenerate some
configure files.
These can be downloaded from gnu.org.

3) Checkout the the insight sources
You can grab the "missing" sources from CVS. If you are in the branch
checked out in #1, simply do:

$ cd src
$ cvs -d:pserver:anoncvs@sourceware.org:/cvs/src update -dA gdb/gdbtk libgui

4) Patch configury and regenerate
Apply the patch I've attached to the sources. This patch will allow you
to use the tcl, tk, itcl, etc that you installed in  #2:

$ pwd
/home/keiths/gdb-7.6/src
$ patch -p1 < /path/to/tcl.m4.patch
patching file config/tcl.m4

Now regenerate the affected configure files [You can safely ignore all
the warnings.]:

$ cd libgui
$ autoreconf
$ cd ../gdb
$ aclocal -Ignulib/import/m4
$ autoconf
$  cd gdbtk
$ autoreconf

4) Build insight
$ pwd
/home/keiths/gdb-7.6
$ mkdir linux; cd linux
$ ../src/configure --prefix=/usr/local
$ make all-gdb install-gdb

That should be all you need to do! It sounds like a lot, but it is
actually pretty simple. Or maybe it is for me because I've been doing
this for a long time.
