Build Instructions
==================

Tools
-----
The commercial PGP was compiled with Microsoft Visual C++ version
5.0, and the installer built with InstallShield 3.00.077, but any
similar version should do. This archive contains everything used
internally by PGP Inc. to build the binaries that PGP ships,
except:

  * The .pdf manuals have been omitted.
  * A large animation (.avi) played during key generation has been
    omitted.
  * The original setup.rul file for installation suffered an error
    if it didn't have the manuals. This has been changed (the
    bHaveManual flag and associated logic) to work properly in
    this case.
  * The install script build.bat was very sensitive to its
    environment and expected things set up in bizarre ways. The
    version published here has been entirely rewritten to be less
    ugly.

There are a number of versions generated: business, personal, OEM,
with RSA or without, etc. The material presented here can build
any of them. Most are fairly similar, but the business security
package has an installer for the admin version which contains an
installer for the user (non-admin) version, so you'll have to
build the latter first.

The Windows code is not arranged to allow simultaneous builds of
different versions, so you are limited to building one version at
a time. Once you have selected a configuration, building the
executables is fully automated, but packaging them for
installation requires attention.

Source code flags
-----------------
Client flags are set in clients/pgp/shared/pgpBuildFlags.h.

  * The first set of flags are for beta and demo versions, set to
    0 for production releases.
  * The second set are for freeware, business, and personal. One
    of these three should be checked.
  * The Admin flag should be 0 unless it's a Business Admin
    build.
  * The No License Number flag should be set to 1 for freeware or
    OEM builds.
  * The NO_RSA flags need to be set to 0 to enable RSA. While you
    can have NO_RSA_KEYGEN set to 1 (keygen disabled) and
    NO_RSA_OPERATIONS set to 0 (operations enabled), the opposite
    is illogical and illegal.

Library flags are set in libs/pgpcdk/priv/include/pgpSDKBuildFlags.h.
There are fewer, as they just indicate library support for various
algorithms.

The RSA flags are like the last two in pgpBuildFlags.h, but use
positive logic; they indicate RSA support, not lack of it as in
pgpBuildFlags.h.

There are some other flags for conventional encryption, but it's
unlikely that you'll want to change them.

Building
--------
  * In Visual C++ 5.0, open the workspace clients/pgp/win32/pgp55.dsw.
  * Using the "Build/Set Active Configuration..." menu item, select
    the "PGP55 - Win32 Release" configuration.
  * Set the option flags in the source code as desired.
  * Start the build (F7).
  * Twiddle your thumbs for a bit while it builds.

InstallShield Theory of Operation
---------------------------------
The most important part of InstallShield is a little language
interpreter in a file called setup.exe; this is what actually
runs to start an installation. It interprets a compiled form of
an input script, traditionally called setup.rul. The interpreter
needs a few auxiliary files such as .dll files to start work
uncompressing, and unpacks some more from a _setup.lib file.
The script can do anything; it's just optimized for program
installation. PGP includes an uninstaller created with
InstallShield.

You build a directory tree and package it up in a compressed
archive, typically called data.z for the installer to unpack on
the target system. Some files (in the tempstuff directory) are
used only during installation and are removed after that.

The archive can be split across multiple disks if necessary;
the interpreter can deal with that cleanly with the aid of a
setup.pkg file telling it where to find things.

Finally, the entire assemblage of interpreter, compiled script,
auxiliary files and archive can be bundled up in a single
self-extracting .exe file.

Installer flags
---------------
win32/Installer/setup/setup.ini needs the correct name and
version number (such as "PGP Freeware version 5.5.2").

win32/Installer/setup/setup.rul contains two TITLE fields. They
are normally identical, unless there are to be two lines on the
InstallShield blue screen. In this case, the first TITLE field
should have a n in it for the line break, and the TITLE2 field
should have a comma and space instead. We have always used only
one line except for Qualcomm Builds, which is "PGP for Personal
Privacy, version 5.5.xnQualcomm OEM".

There are a number of flags in setup.rul which should be set to
values corresponding to the program options. Most are in a block
up at the front, except for PRODUCT_VERSION. (And a dozen places
that "5.5" is referred to.)

The ISADMIN flag has three possible settings. TRUE and FALSE are
for Business Security builds, TRUE for admin and FALSE for user.
Personal Privacy and Freeware builds use NULL.

PGP_NO_LICENSE_NUMBER is analogous to the one mentioned above,
set to 1 for a freeware or OEM build.

IS_QUALCOMM_BUILD is, well, whether or not it's a Qualcomm OEM
build.

Arranging the installation
--------------------------
The manual part of the installation involves building an image
in the Installer/DATA directory of what you want installed. Not
complicated, but tedious. (All directories mentioned here are
relative to clients/pgp/win32 unless indicated otherwise.)

Clean up the installer directory Installer/DATA/. Remove any
CVS or RCS subdirectories or anything else that might confuse
InstallShield.

Create the directories

  Installer/DATA/Admin/ (Business Security Admin only)
  Installer/DATA/Admin/ClientInstaller/ (likewise)
  Installer/DATA/Eudora/
  Installer/DATA/Eudora/Regular/
  Installer/DATA/Eudora/fourdoto/
  Installer/DATA/Exchange/
  Installer/DATA/Pgp55/
  Installer/DATA/WinSysDir/
  Installer/DATA/Pgp55/signatures/ (Not for unsigned test builds)
  Installer/DATA/Pgp55/signatures/Eudora 3 plugin sig/ (likewise)
  Installer/DATA/Pgp55/signatures/Eudora 4 plugin sig/ (likewise)
  Installer/Uninstaller/tempstuff/

The manual in Adobe PDF format is not included in this book, but
if it were, you would create an Installer/DATA/Manual/ directory
for it.

Go to PGP55/Release/. There will be a whole bunch of executables
and .dll's in there. Copy these to the following directories in
DATA/:

pgpplugin.dll       -> DATA/Eudora/Regular/
EudoraPluginV4.dll  -> DATA/Eudora/fourdoto/pgpplugin.dll
pgpExch.dll         -> DATA/Exchange/
PGPadmin.exe        -> DATA/Admin/ (Business Security admin only)
PGPkeys.exe         -> DATA/Pgp55/
PGPlog.exe          -> DATA/Pgp55/
PGPtools.exe        -> DATA/Pgp55/
PGPtray.exe         -> DATA/Pgp55/
PGP55cd.dll         -> DATA/WinSysDir/
PGP55km.dll         -> DATA/WinSysDir/
PGP55mn.dll         -> DATA/WinSysDir/
PGP55rd.dll         -> DATA/WinSysDir/
PGP55sc.dll         -> DATA/WinSysDir/
PGPsdk.dll          -> DATA/WinSysDir/
PGPsdkKS.dll        -> DATA/WinSysDir/

Use the setbmps.bat script to copy the appropriate splash-screen
bitmaps into the tempstuff directories. Run setbmps X, where X
is b for Business Security, p for Personal Privacy, or f for
freeware.

For Business Security builds, copy

  Installer/keyrings/BUSpubring.pkr -> Installer/tempstuff/pubring.pkr

For other builds, copy

  Installer/keyrings/OTHERpubring.pkr -> Installer/tempstuff/pubring.pkr

Also copy

  Installer/Extras/eudora.url   -> Installer/DATA/Pgp55/
  Installer/Extras/adobe.url    -> Installer/DATA/Pgp55/

The commercial PGP also includes keygen.avi in the DATA/Pgp55/
directory, but it is a large (800K) animation which serves only to
entertain you while a key is being generated, so has been omitted
from this book. The program works fine without it; it just displays
a boring blank window during key generation.

Next, install the correct readme, help, etc. files as follows. Note
that you'll have to skip the steps involving the .pdf manuals, as
they aren't included in this book.

Business Security Build with full RSA support:
----------------------------------------------
Extras/Readme.txt        -> DATA/Pgp55/
licenses/license.txt     -> DATA/Pgp55/
Help/pgp55.CNT           -> DATA/Pgp55/
Help/pgp55.hlp           -> DATA/Pgp55/
Extras/PGP55win.pdf      -> DATA/Manual/

For an Admin build, also:
-------------------------
Extras/cso.pdf           -> DATA/Admin/
non-admin disk images    -> DATA/Admin/ClientInstaller/

Personal Privacy build with RSA support (but not keygen):
---------------------------------------------------------
Extras/Readme.txt        -> DATA/Pgp55/
licenses/license.txt     -> DATA/Pgp55/
Help/pgp55PER.CNT        -> DATA/Pgp55/pgp55.CNT
Help/pgp55PER.hlp        -> DATA/Pgp55/pgp55.hlp
Extras/PGP55winPER.pdf   -> DATA/Manual/PGP55win.pdf

Personal Privacy build without RSA support:
-------------------------------------------
Extras/Readme.txt        -> DATA/Pgp55/
licenses/perdhlic.txt    -> DATA/Pgp55/
Help/pgp55PERDH.CNT      -> DATA/Pgp55/pgp55.CNT
Help/pgp55PERDH.hlp      -> DATA/Pgp55/pgp55.hlp
Extras/PGP55winPERDH.pdf -> DATA/Manual/PGP55win.pdf

Freeware build:
---------------
Extras/ReadmeFREE.txt    -> DATA/Pgp55/Readme.txt
licenses/freelic.txt     -> DATA/Pgp55/license.txt
Help/pgp55FREE.CNT       -> DATA/Pgp55/pgp55.CNT
Help/pgp55FREE.hlp       -> DATA/Pgp55/pgp55.hlp

Edit DATA/Pgp55/Readme.txt to put in the correct date,
version number, etc.

Finally
-------
Check Installer/Build.bat and replace the reference to
c:ishield32 at the front with wherever you have InstallShield.
You are now ready to invoke InstallShield's various components
on the directory tree you have created. This part is automated;
from the Installer/ directory, run build.bat. It pauses after
each script compile, but you should be alert for other errors.
(exebuild is particularly error-prone.)

This will package up the uninstaller, add it to the DATA
directory, package up the DATA directory, and split it among
disk images in the Installer/Images/ directory. And finally,
in Installer/ will be a complete self-extracting installation
archive pgpinst.exe.
