Windows DLL Build instructions using nmake build system 2020-10-15 Harald.Oehlmann@elmicron.de 2023-04-23 Brian O'Hagan Properties: - 64 bit DLL - VisualStudio 2015 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 dependency on OPENSSL DLL's ----------------------------- 1) Build OpenSSL static libraries: set SSLBUILD=\path\to\build\dir set SSLINSTALL=\path\to\install\dir set SSLCOMMON=\path\to\common\dir (1a) Get OpenSSL https://github.com/openssl/openssl/releases/download/OpenSSL_1_1_1t/openssl-1.1.1t.tar.gz Unpack OpenSSL source distribution to %SSLBUILD% (1b) Install Perl from https://strawberryperl.com/ https://strawberryperl.com/download/5.32.1.1/strawberry-perl-5.32.1.1-64bit.msi Install to C:\Strawberry\perl (1c) Install NASM Assembler from https://www.nasm.us/ https://www.nasm.us/pub/nasm/releasebuilds/2.16.01/win64/nasm-2.16.01-installer-x64.exe Install to: C:\Program Files\NASM (1d) Configure At Visual Studio x86 native prompt: set Path=%PATH%;C:\Program Files\NASM;C:\Strawberry\perl\bin perl ..\Configure VC-WIN64A no-shared no-filenames threads no-ssl2 no-ssl3 --api=1.1.0 --prefix="%SSLINSTALL%" --openssldir="%SSLCOMMON%" -DOPENSSL_NO_DEPRECATED # Not used options: no-asm no-zlib no-comp no-ui-console no-autoload-config (1e) Build OpenSSL nmake nmake test nmake install ----------------------------- 2) Build TclTLS set BUILDDIR=\path\to\build\dir set TCLINSTALL=\path\to\tcl\dir 2a) Unzip distribution to %BUILDDIR% 2b) Start BASH shell (MinGW62 Git shell) cd %BUILDDIR% ./gen_dh_params > dh_params.h od -A n -v -t xC < 'library/tls.tcl' > tls.tcl.h.new.1 sed 's@[^0-9A-Fa-f]@@g;s@..@0x&, @g' < tls.tcl.h.new.1 > generic/tls.tcl.h rm -f tls.tcl.h.new.1 2c) Start Visual Studio shell cd %BUILDDIR%\win nmake -f makefile.vc TCLDIR=%TCLINSTALL% SSL_INSTALL_FOLDER=%SSLINSTALL% nmake -f makefile.vc install TCLDIR=c:\test\tcl8610 INSTALLDIR=%TCLINSTALL% SSL_INSTALL_FOLDER=%SSLINSTALL% ----------------------------- 3) Test Start tclsh or wish package require tls 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
