	Windows DLL Build instructions using nmake build system
	2020-10-15 [email protected]
	2023-04-23 Brian O'Hagan

Properties:
- 32 bit DLL
- 64 bit DLL
- VisualStudio 2015
Note: Vuisual C++ 6 does not build OpenSSL (long long syntax error)
Note: Visual C++ 6 does not build OpenSSL (long long syntax error)
- Cygwin32 (temporary helper, please help to replace by tclsh)
- OpenSSL statically linked to TCLTLS DLL.
Note: Dynamic linking also works but results in a DLL dependeny on OPENSSL DLL's
Note: Dynamic linking also works but results in a DLL dependency on OPENSSL DLL's

1) Build OpenSSL static libraries:

(1a) Get OpenSSL
  https://github.com/openssl/openssl/releases/download/OpenSSL_1_1_1t/openssl-1.1.1t.tar.gz

OpenSSL source distribtution unpacked in:
c:\test\tcltls\Openssl_1_1_1h
  OpenSSL source distribution unpacked in:
  C:\Users\Brian\Documents\Source\Build\openssl-1.1.1t

(1b) Install Perl from https://strawberryperl.com/
- Install Perl from http://strawberryperl.com/download/5.32.0.1/strawberry-perl-5.32.0.1-32bit.msi
  to C:\perl
  https://strawberryperl.com/download/5.32.1.1/strawberry-perl-5.32.1.1-64bit.msi
  to C:\Strawberry\perl
  (ActivePerl failed due to missing 32 bit console module)
- Install NASM Assembler:

(1c) Install NASM Assembler from https://www.nasm.us/
https://www.nasm.us/pub/nasm/releasebuilds/2.15.05/win32/nasm-2.15.05-installer-x86.exe
  to C:\Program Files (x86)\NASM
  
-> Visual Studio x86 native prompt.
  https://www.nasm.us/pub/nasm/releasebuilds/2.16.01/win64/nasm-2.16.01-installer-x64.exe
  to C:\Program Files\NASM

(1d)
- Configure
  At Visual Studio x86 native prompt:

set Path=%PATH%;C:\Program Files (x86)\NASM;C:\Perl\perl\bin
set Path=%PATH%;C:\Program Files\NASM;C:\Strawberry\perl\bin

perl Configure VC-WIN32 --prefix=c:\test\tcltls\openssl --openssldir=c:\test\tcltls\openssldir no-shared no-filenames threads
perl ..\Configure VC-WIN64A no-asm no-ssl3 no-zlib no-comp no-ui-console no-autoload-config --api=1.1.0 --prefix="%installdir%" --openssldir="%commoninstalldir%" -DOPENSSL_NO_DEPRECATED


nmake
nmake test
namke install
nmake install

2) Build TCLTLS

Unzip distribution in:
c:\test\tcltls\tcltls-1.7.22
2a) Unzip distribution in:
C:\Users\Brian\Documents\Source\Build\tcltls-b5c41cdeb6

-> start cygwin bash prompt
2b) Start BASH shell (MinGW62 Git shell)

cd /cygdrive/c/test/tcltls/tcltls-1.7.22
cd /c/Users/Brian/Documents/Source/Build/tcltls-b5c41cdeb6
./gen_dh_params > dh_params.h

od -A n -v -t xC < 'tls.tcl' > tls.tcl.h.new.1
sed 's@[^0-9A-Fa-f]@@g;s@..@0x&, @g' < tls.tcl.h.new.1 > tls.tcl.h
rm -f tls.tcl.h.new.1

-> Visual Studio x86 native prompt.
2c) Start Visual Studio shell

cd C:\test\tcltls\tcltls-1.7.22\win
cd C:\Users\Brian\Documents\Source\Build\tcltls-b5c41cdeb6\win

nmake -f makefile.vc TCLDIR=c:\test\tcl8610 SSL_INSTALL_FOLDER=C:\test\tcltls\openssl

nmake -f makefile.vc install TCLDIR=c:\test\tcl8610 INSTALLDIR=c:\test\tcltls SSL_INSTALL_FOLDER=C:\test\tcltls\openssl

3) Test

Start tclsh or wish

lappend auto_path {C:\test\tcltls\tls1.7.22}
package require tls

A small "1.7.22" showing up is hopefully the end of this long way...
package require http
http::register https 443 [list ::tls::socket -autoservername true]
set tok [http::data [http::geturl https://www.tcl-lang.org]]
::http::cleanup $tok

Modified win/makefile.vc from [2103458bde] to [02934efb2a].

# Nmake is a pretty weak environment in syntax and capabilities
# so this file is necessarily verbose. It's broken down into
# the following parts.
#
# 0. Sanity check that compiler environment is set up and initialize
#    any built-in settings from the parent makefile
# 1. First define the external tools used for compiling, copying etc.
#    as this is independent of everything else.
# 2. Figure out our build structure in terms of the directory, whether
#    we are building Tcl or an extension, etc.
# 3. Determine the compiler and linker versions
# 4. Build the nmakehlp helper application
# 5. Determine the supported compiler options and features
# 6. Parse the OPTS macro value for user-specified build configuration
# 7. Parse the STATS macro value for statistics instrumentation
# 8. Parse the CHECKS macro for additional compilation checks
# 9. Extract Tcl, and possibly Tk, version numbers from the headers
# 10. Based on this selected configuration, construct the output
#     directory and file paths
# 11. Construct the paths where the package is to be installed
# 12. Set up the actual options passed to compiler and linker based
#     on the information gathered above.
# 13. Define some standard build targets and implicit rules. These may
#     be optionally disabled by the parent makefile.
# 14. (For extensions only.) Compare the configuration of the target
#     Tcl and the extensions and warn against discrepancies.
#
# One final note about the macro names used. They are as they are
# for historical reasons. We would like legacy extensions to
# continue to work with this make include file so be wary of
# changing them for consistency or clarity.

# 0. Sanity check compiler environment

#           0 -> link to static C runtime for static Tcl build.
#           Does not impact shared Tcl builds (STATIC_BUILD == 0)

# USE_THREAD_ALLOC - 1 -> Use a shared global free pool for allocation.

# TMP_DIR - directory where object files are created
# OUT_DIR - directory where output executables are created
# Both TMP_DIR and OUT_DIR are defaulted only if not defined by the
# parent makefile (or command line). The default values are
# based on BUILDDIRTOP.
# STUBPREFIX - name of the stubs library for this project
# PRJIMPLIB - output path of the generated project import library
# PRJLIBNAME - name of generated project library
# PRJLIB     - output path of generated project library
