openssl_android_scripts

Scripts for build of the openssl lib (for Android x86, x86_6, armeabi-v7a, arm64-v8a).

Windows x86_64 (windows-x86_64/):

openssl-1.1.1i:

    http://smansoft.com/openssl_android_scripts/windows-x86_64/openssl-1.1.1i.android.zip

1. Install Cygwin (including perl, make, gcc for cygwin):

   Cygwin:

    https://sourceforge.net/projects/mingw-w64/
   

2. Add path to Cygwin bin:

    C:\cygwin64
    C:\cygwin64\bin
    C:\cygwin64\sbin
    C:\cygwin64\usr\sbin
    C:\cygwin64\usr\local\bin
   

3. Unpack/install Android.ndk; for example:

    D:/sman/sdk/android/android-sdk.cur/ndk-bundle
   

4. Add Environment Variable ANDROID_NDK_HOME:

    ANDROID_NDK_HOME="d:/sman/sdk/android/android-ndk-r21d"
   

5. Add to the top of path:

    %ANDROID_NDK_HOME%\toolchains\llvm\prebuilt\windows-x86_64\bin
   

6. Add to the top of path:

    %ANDROID_NDK_HOME%/prebuilt\windows-x86_64\bin
   

7. Go to unpacked archive;

8. create in unpacked directory (OPENSSL sources direcroty) new subdirectory: _build;

9. cd ./_build;

   Note: You can create directory _build somewhere or use some other directory for build. Just you need setup variables in the script: _build_openssl.sh.

10. copy file: _build_openssl.sh here;

11. setup in _build_openssl.sh

    export API_LEVEL=23
    

12. setup in _build_openssl.sh

    BUILD_TARGETS="armeabi-v7a arm64-v8a x86 x86_64";
    

    i.e. remove unnecessary or add some other platforms;

13. run:

    bash ./_build_openssl.sh
    

14. built libs and includes will be copied to:

    ./libs/arm64-v8a
    ./libs/armeabi-v7a
    ./libs/x86
    ./libs/x86_64 
    
    ./include
    

Note:

1. This archive contains changed files:

    Configurations/15-android.conf;
    
    Configure (build of apps is disabled, only build of static libs (.a) is provided);
   

2. All paths (in script) should contains only "/" instead "", i.e.:

    D:/sman/sdk/android/android-sdk.cur/ndk-bundle
   

3. Path in ANDROID_NDK_HOME should contains only "/" instead "" too.

4. "" can be used only in PATH:

    %ANDROID_NDK_HOME%\toolchains\llvm\prebuilt\windows-x86_64\bin
    %ANDROID_NDK_HOME%\prebuilt\windows-x86_64\bin
    as operation system (Windows) requires "\";
   

5. open file

    Configurations\15-android.conf
   

   and update:

   this:

        # see if there is NDK clang on $PATH, "universal" or "standalone"
        if (which("clang") =~ m|^$ndk/.*/prebuilt/([^/]+)/|) {
            my $host=$1;
            # harmonize with gcc default
            my $arm = $ndkver > 16 ? "armv7a" : "armv5te";
            (my $tridefault = $triarch) =~ s/^arm-/$arm-/;
            (my $tritools   = $triarch) =~ s/(?:x|i6)86(_64)?-.*/x86$1/;

        } elsif (-f "$ndk/AndroidVersion.txt") {    #"standalone toolchain"
            my $cc = $user{CC} // "clang";
            # One can probably argue that both clang and gcc should be
            # probed, but support for "standalone toolchain" was added
            # *after* announcement that gcc is being phased out, so
            # favouring clang is considered adequate. Those who insist
            # have option to enforce test for gcc with CC=gcc.
            if (which("$triarch-$cc") !~ m|^$ndk|) {
                die "no NDK $triarch-$cc on \$PATH";
            }
            $user{CC} = $cc;
            $user{CROSS_COMPILE} = "$triarch-";
        } elsif ($user{CC} eq "clang") {
            die "no NDK clang on \$PATH";
        } else {
            if (which("$triarch-gcc") !~ m|^$ndk/.*/prebuilt/([^/]+)/|) {
                die "no NDK $triarch-gcc on \$PATH";
            }
            $cflags .= " -mandroid";
            $user{CROSS_COMPILE} = "$triarch-";
        }
   

   to:

            my $host=$1;
            # harmonize with gcc default
            my $arm = $ndkver > 16 ? "armv7a" : "armv5te";
            (my $tridefault = $triarch) =~ s/^arm-/$arm-/;
            (my $tritools   = $triarch) =~ s/(?:x|i6)86(_64)?-.*/x86$1/;
            $cflags .= " -target $tridefault "
                    .  "-gcc-toolchain \$($ndk_var)/toolchains"
                    .  "/$tritools-4.9/prebuilt/$host";

            }
   

   i.e. should be executed code, that "clang" is found (as 'clang' is used instead 'gcc');

6. open file (perl script)

   Configure

   and update:

   this:

    $config{dirs} = [ "crypto", "ssl", "engines", "apps", "test", "util", "tools", "fuzz" ];
   

   to:

    $config{dirs} = [ "crypto", "ssl", "engines" ];
   

   i.e. build of apps and other modules should be excepted (only static libs .a);

Linux (linux-x86_64/):

openssl-1.1.1i:

    http://smansoft.com/openssl_android_scripts/linux-x86_64/openssl-1.1.1i.android.tar.gz

1. Add Environment Variables ANDROID_NDK_HOME and ANDROID_SDK_HOME:

    export ANDROID_SDK_HOME=/home/strgs/sdb.07/sman/sdk/android/android-sdk.cur
    export ANDROID_NDK_HOME=/home/strgs/sdb.07/sman/sdk/android/android-ndk-r21d
   

2. Add follow path to $PATH Environment Variable:

    export PATH=${ANDROID_NDK_HOME}/toolchains/llvm/prebuilt/linux-x86_64/bin:${PATH};
   

3. Go to unpacked archive;

4. Open file (perl script) "Configure"

   and update this line:

    $config{dirs} = [ "crypto", "ssl", "engines", "apps", "test", "util", "tools", "fuzz" ];
   

   to:

    $config{dirs} = [ "crypto", "ssl", "engines" ];
   

   i.e. build of apps and other modules should be excepted (only static libs .a);

5. Create in unpacked directory (OPENSSL sources direcroty) new subdirectory: _build;

6. cd ./_build;

   Note: You can create directory _build somewhere or use some other directory for build. Just you need setup variables in the script: _build_openssl.sh.

7. copy file: _build_openssl.sh here;

8. setup in _build_openssl.sh

    export API_LEVEL=23;
   

9. setup in _build_openssl.sh

    BUILD_TARGETS="armeabi-v7a arm64-v8a x86 x86_64";
   

   i.e. remove unnecessary or add some other platforms;

10. run:

    bash ./_build_openssl.sh
    

11. built libs and includes will be copied to:

    ./libs/arm64-v8a
    ./libs/armeabi-v7a
    ./libs/x86
    ./libs/x86_64
    
    ./include
