openssl

Build differently named 32 and 64 bit binaries for OpenSSL on Windows

CREDITS

Ideas were borrowed from here.

PREREQUISITES

1. openssl source: tested with openssl-1.0.2s.tar.gz.
2. nasm binary: tested with nasm-2.14.02-win32.zip.
3. fnr binary: tested with fnr.zip.
4. perl 5: tested with ActivePerl 5.28.1.2801 x64.
5. msvc: tested with MSVS 2019 Community Edition.
6. openssl build scripts: tested with these scripts.

STEPS

1. Place nasm.exe in C:\local\libs\nasm\bin
2. Place fnr.exe in C:\local\libs\fnr\bin
3. Install Perl 5 (ActivePerl recommented; it will install to C:\Perl64)
4. Extract scripts in openssl_1.0.x_build_scripts.7z to C:\local\temp\openssl
5. Extract openssl source to C:\local\temp\openssl (so that source is in C:\local\temp\openssl\openssl-1.0.x)

At this point, the build process can be fully automated by placing these scripts into C:\local\temp\openssl and running Build.bat. The automated scripts makes steps 7 and 8 unnecessary, but they've been added here for convenience and reference, and in case issues with the automated scripts arise in the future.

Steps 7 and 8 require saving these scripts into C:\local\temp\openssl.

7. Build the x64 binaries (scripts assume the above mentioned locations)

   1. copy the folder openssl-1.0.x to openssl-1.0.x_x64. If the folder already existed, delete it first!
   2. Use MSVS to replace all occurrences (in openssl-1.0.x_x64 folder) of the text listed below (Open MSVS without a project, Edit -> Find and Replace -> Replace in Files (include subfolders, match case)):
      • eay32 -> eay64 (70 occurrences)
      • 32dll -> 64dll (23 occurrences)
      • openssl.exe -> openssl64.exe (28 occurrences)
   3. Run Buildx64_1.bat. Should report 'Configured for VC-WIN64A'.
   4. Use MSVS to replace all occurrences (in openssl-1.0.x_x64 folder) of the following text:
      • EAY32 -> EAY64 (2 occurrences)
      • 32dll -> 64dll (2 occurrences)
      • E_EXE=openssl -> E_EXE=openssl64 (3 occurrences)
   5. Run Buildx64_2.bat
      • Should report 'passed all tests'
      • Files will be placed in C:\local\libs\openssl
      • Output is libeay64.dll (uses libeay64.lib)

8. Build the x86 binaries (scripts assume the above mentioned locations)

   1. copy the folder openssl-1.0.x to openssl-1.0.x_x86. If the folder already existed, delete it first!
   2. Use MSVS to replace all occurrences (in openssl-1.0.x_86 folder) of the following text:
      • openssl.exe -> openssl32.exe (28 occurrences)
   3. Run Buildx64_1.bat
      • Should report 'Configured for VC-WIN32'
   4. Use MSVS to replace all occurrences (in openssl-1.0.x_x86 folder) of the following text:
      • E_EXE=openssl -> E_EXE=openssl32 (4 occurrences)
   5. Run Buildx64_2.bat
      • Should report 'passed all tests'
      • Files will be placed in C:\local\libs\openssl
      • Output is libeay64.dll (uses libeay64.lib)
