This explains how to construct a development version of NEURON using
anonymous cvs.

1) create a neuron directory which will hold the entire development
   tree and cd to it. On my machine it is $HOME/neuron

2) you will always need this to do the original checkout and get the updates
   export CVS_RSH=ssh (for bash)
   setenv CVS_RSH ssh (for tcsh)
   (best put in .bashrc or .tcshrc since you may forget this later)
	If this is missing, then cvs commands will seem to hang for
	a minute or so and then fail with the message:
		miris.med.yale.edu: Connection refused


3)
Checkout and build the InterViews release branch (this is only done once)
  
   If you have a current version 15 of InterViews you can use it and skip
this step (until and  unless interviews starts getting revised again).

cvs -d :ext:anonymous@www.neuron.yale.edu:/home/cvsroot checkout \
 -r iv-rel15 -d iv iv
when the password is requested type "neuron" without the double quotes.
	If the cvs command hangs for a minute and then fails with the
	message:
		miris.med.yale.edu: Connection refused
	then your CVS_RSH environment variable is not ssh.
	The first time cvs connects to www.neuron.yale.edu your machine
	may respond with the message:
The authenticity of host 'www.neuron.yale.edu (130.132.220.62)' can't be established.
RSA key fingerprint is 5d:85:7c:b0:e2:4e:4f:13:d8:f0:b8:15:70:7d:db:2a.
Are you sure you want to continue connecting (yes/no)?
	type "yes" without the quotes and it will continue to the point
	where it asks for the password. (Then type "neuron" without the quotes.)

I build InterViews as follows (assuming that $IV is set to the source
code location)
    cd $IV
    sh build.sh
    make
    make install
Note that the above will install in $IV/i686 if you are on a linux machine.
If the build.sh command fails, you may need more recent versions of
autoconf and automake. Mine are
[hines@NeuronDev nrn-5.4]$ automake --version
automake (GNU automake) 1.6.3
[hines@NeuronDev nrn-5.4]$ autoconf --version
autoconf (GNU Autoconf) 2.53
Any newer versions will also work. See more info below.

4) Check out the neuron development branch
cvs -d :ext:anonymous@www.neuron.yale.edu:/home/cvsroot checkout -r nrn-dev5_4 -d nrn nrn
when the password is requested type "neuron" without the double quotes. 
  

    You may wish to rename this directory for clarity.

You must construct some distribution files using the four commands:
aclocal
autoheader
automake
autoconf

(There are some potential pitfalls in the installation of these programs
  I recommend building
from source obtained from www.gnu.org.  This will place things in /usr/local
  Then make sure that
the programs being run are in /usr/local/bin and not in /usr/bin.)

5) It is useful to keep the source and build directories separate.  In
this way one can readily 
build neuron with different flags for the
purposes of profiling, code coverage, static vs shared libraries, etc. without
doing a "make clean" and losing all the compiled objects.
Additionally, a separate build library allows you to build 
for different architectures with the same source tree.
In short, it is best not to build anything in the source tree.

6) Let's assume that InterViews is installed in $IV and that neuron
source is located in $NRNS
These variables can be set using export (bash) or setenv (tcsh).
Now you need to create a build directory with
a name that indicates the purpose of this build (eg nrn-5.4) and cd
to this directory.

Now the configure command is:
  $NRNS/configure --prefix=`pwd` --srcdir=$NRNS --with-iv=$IV
you can use relative addressing (eg ..) for everything except -with-iv=
since this will need to be accessed from deep within the tree

Make is done in the usual way:
  make
  make install

the path is then set to include $PWD/i686/bin

If "make" fails or you don't seem to be getting the latest changes,
it may be because your working copy is not using the
nrn-dev5_4 branch. There should be a $NRNS/CVS/Tag file with the contents
Tnrn-dev5_4
If the file is missing or indicates you are using the wrong branch
then switch to the nrn-dev5_4 branch with
  cd $NRNS
  cvs update -r nrn-dev5_4

7) An example for profiling:

Profiling (using bash)
# create a 'profile' directory; cd profile; export NPROF=$PWD
export CFLAGS="-pg"
export CXXFLAGS="-pg"
export linux_nrnmech=no
$NRNS/configure --disable-shared --prefix=$NPROF --srcdir=$NRNS
make
make install
# cd to some model to test
$NPROF/i686/bin/nrnivmodl
i686/special batch_.hoc
gprof i686/special > temp


How to make a neuron rpm.
1) Install InterViews in /usr/local/iv
./configure --prefix=/usr/local/iv
make
su
make install

2) Install NEURON in /usr/local/nrn
../nrn/configure --prefix=/usr/local/nrn --with-iv=/usr/local/iv \
  --srcdir=../nrn --enable-rpm-rules --with-nrnjava --disable-static
make
su
make install
make rpm
This will create something like
/usr/src/redhat/RPMS/i386/nrn-5.5-1.i386.rpm


How to make a Mac dmg
The following is out of date in some points. e.g. the CopyDisk refers to
osx 10.2 and nowadays we use hdiutil to do everything under shell script control.
See cvs2osx11dmg for a script that specifies the entire process from cvs to
dmg. The x11 refers to the use of the xdarwin version of X11.

1) Install InterViews in /Applications/NEURON-5.5/nrn
./configure --prefix=/Applications/NEURON-5.5/iv

2) Install NEURON in /Applications/NEURON-5.5/nrn
./configure --prefix=/Applications/NEURON-5.5/nrn --with-iv=/Applications/NEURON-5.5/iv

3) With a finder window view the directory
/Applications/NEURON-5.5/nrn/powerpc/bin
This is required for the applescript to find the macnrn.term file.
Note: Don't bother, now done in the src/mac/after-install script

4) The nrngui, mknrndll, neurondemo, mos2nrn, idraw applescripts should be
in /Applications/NEURON-5.5 . Reuse the applescripts from a previous installation
along with their icons.
The applescript text is nrn/src/mac/prototype_applescript.txt .
Note: Now done by "make install" when src/mac/launch_inst.sh script is called.

5) sh nrn/src/mac/after-install.sh
to clean up the installation directory, remove irrelevant executables,
strip the important executables, and create the neurondemo. This will reduce
the size of an installation package from more than 12MB to less than 4MB.

6) Create a NEURON-5.5.dmg file using /Applications/Utilities/CopyDisk.
It is a good idea to create a NEURON-5.5 folder somewhere and temporarily
drag the /Applications/NEURON-5.5 folder to it and copy the former in order
to get a dmg file which when opened shows the NEURON-5.5 folder instead of
the contents. This makes it easier to install by dragging the NEURON-5.5
folder to where the user wants it (/Applications).
Note: now done by src/mac/mkdmg.sh .
