ossl_ics-openvpn

This script is inspired from platform_external_openssl by Arne Schwabe for ics-openvpn and works with OpenSSL 3.0 and greater.

Supported Android-Targets: arm | arm64 | x86 | x86_64

Supported CMake Lib-Types: STATIC | SHARED

This script is refactored and reduced to its minimum, using only some parts of its origin. The goal was to automate the necessary steps to create a prepared OpenSSL-Source which can be used in ics-openvpn CMake. The original adopted script by Arne Schwabe is completely static, and has to adapted with each Major OpenSSL-Update to keep working. Downgrade or Upgrade isn't possible without mandatory changes in the original files like [import_openssl.sh] or [openssl.cmake], this is a big issue for maintenance. With my script it's possible to use shared libtype in CMakeLists.txt to reduce the APK-Size significantly, in tests up to 50% downsizing is possible (Universal-APK).

Main functions:

• Use the official OpenSSL Git-Repo
• Alternative use of *.tar.gz Archives from Path or Web
• Search for necessary *.c files in Makefile
• Read CPP/C-Flags from Makefile
• Read ASM Compiler-Flags from configdata.pm
• Create Assembler-Code (Perl-ASM)
• Expand *.in to .c/.h/.icx files
• Apply patches from Patch-Folder
• Create openssl.cmake for ics-openvpn (Automatic)

Usage (Interactive):

./generate.sh

Usage (Tar/Web-Method):
