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) - Git MinGW or MS WSL shell to convert tls.tcl into .h file - 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 Open SSL 1.1.1 At Visual Studio x64 native prompt: cd %SSLBUILD% 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) Configure Open SSL 3.0+ At Visual Studio x64 native prompt: cd %SSLBUILD% set Path=%PATH%;C:\Program Files\NASM;C:\Strawberry\perl\bin perl ..\Configure VC-WIN64A no-shared no-filenames threads no-ssl2 no-ssl3 --prefix="%SSLINSTALL%" --openssldir="%SSLCOMMON%" # Not used options: no-asm no-zlib no-comp no-ui-console no-autoload-config (1f) Build OpenSSL nmake nmake test nmake install ----------------------------- 2) Build TclTLS set BUILDDIR=\path\to\build\tcltls set TCLINSTALL=\path\to\tcl set INSTALLDIR=%TCLINSTALL%\lib set SSLINSTALL=\path\to\openssl\dir 2a) Unzip distribution to %BUILDDIR% 2b) Start Visual Studio shell At Visual Studio x64 native prompt: cd %BUILDDIR%\win nmake -f makefile.vc TCLDIR=%TCLINSTALL% SSL_INSTALL_FOLDER=%SSLINSTALL% nmake -f makefile.vc install TCLDIR=%TCLINSTALL% INSTALLDIR=%INSTALLDIR% 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
