Compiling Conscrypt

In this step, gradle-4.8.1-all is automatically downloaded from /root/.gradle/wrapper/dists.

2

cd /home/conscrypt
./gradlew

If a proxy is used, run the following commands. Configure the host name, port number, user name, and password of the proxy based on the actual proxy environment.

./gradlew -Dhttp.proxyHost=proxysg.huawei.com -Dhttp.proxyPort=8080 -Dhttps.proxyHost=proxysg.huawei.com -Dhttps.proxyPort=8080  -Dhttps.proxyUser= -Dhttps.proxyPassword=  -Dhttp.proxyUser= -Dhttp.proxyPassword=

If the following error message is displayed when you run ./gradlew:

use the following method to resolve the problem:

1. Go to the /root/.gradle/wrapper/dists/gradle-4.8.1-all/6fmj4nezasjg1b7kkmy10xgo2 directory.

   cd /root/.gradle/wrapper/dists/gradle-4.8.1-all/6fmj4nezasjg1b7kkmy10xgo2

   Note: The 6fmj4nezasjg1b7kkmy10xgo2 directory may be different. Replace the directory with the actual one.

2. Download the Gradle source code.

   1	wget https://services.gradle.org/distributions/gradle-4.8.1-all.zip --no-check-certificate

3. Decompress the gradle-4.8.1-all.zip package.

   1	unzip gradle-4.8.1-all.zip

4. Go to the /home/conscrypt directory.

   1	cd /home/conscrypt

5. Perform the compilation again (set the proxy host, port, user name, and password based on the actual environment):

   ./gradlew -Dhttp.proxyHost=proxysg.huawei.com -Dhttp.proxyPort=8080 -Dhttps.proxyHost=proxysg.huawei.com -Dhttps.proxyPort=8080  -Dhttps.proxyUser= -Dhttps.proxyPassword=  -Dhttp.proxyUser= -Dhttp.proxyPassword=

1. Open the build.gradle file.

   1	vim build.gradle

2. Press i to enter the insert mode and add aarch64 to the file name extension of the original 64-bit build file.
   • Add the following code to line 12:

         arm64 = 'aarch64'

     

   • Modify line 21.

             nativeClassifier64Bit = classifierFor(osName, arm64)

     

3. Add the platform configuration to line 291.

           linux_aarch64 {
                architecture "aarch64"
                operatingSystem "linux"
           }

   

4. Change the 64-bit architecture to linux_aarch64 when building jni-library.
   • Comment out line 304 and change arch64Name in line 305 to linux_aarch64.

                 //if (build32Bit) { targetPlatform arch32Name }
                if (build64Bit) { targetPlatform "linux_aarch64" }

     

   • Modify the content in line 326 to aarch64.

     

5. Add the address of the specified header file to args during Clang or GCC compilation.

   Modify lines 339 and 342 to ensure that they are consistent with the GCC path.

   On CentOS, modify the file as follows:

                                   "-I$jniSourceDir/main/include",
                                   "-I$jniSourceDir/unbundled/include",
                                   "-I/usr/include/c++/4.8.2",
                                   "-I/usr/include/c++/4.8.2/aarch64-redhat-linux",

   

   On openEuler, modify the file as follows:

   "-I$jniSourceDir/main/include",
   "-I$jniSourceDir/unbundled/include",
   "-I/usr/include/c++/7.3.0",
   "-I/usr/include/c++/7.3.0/aarch64-linux-gnu",

   

6. Modify the code for generating library information.
   • Modify lines 419 to line 428.

                 def archName = binary.targetPlatform.architecture.name
                 def archNameR = archName
                 if(archName == 'aarch64'){
                   archNameR = 'aarch_64'
                 }
                 archName = archName.replaceAll('-','_')
                 def classifier = classifierFor(osName, archName)
                 def classifierR = classifierFor(osName,archNameR)
                 def sourceSetName = sourceSetName("$classifier")
                 def source = binary.sharedLibraryFile

     

   • Change the content in lines 435 and 437 to classifierR.

     

7. Press Esc, type :wq!, and press Enter to save the file and exit.

1. Open the build.gradle file.

   1	vim build.gradle

2. Press i to enter the insert mode, modify line 39, and add lines 40 to 43.

                    gcc(Gcc){
                     target("linux_aarch64") {
                     cppCompiler.executable = "/usr/bin/gcc"
                     }
                   }

   

3. Add the following code to lines 160 to 162:

       dependencies {
           errorprone("com.google.errorprone:error_prone_core:2.3.3")
       }

   

4. Press Esc, type :wq!, and press Enter to save the file and exit.

1. Create a gradle.properties file.

   1	touch gradle.properties

2. Add the following content to the file, save the file, and exit. Configure the host name, port number, user name, and password of the proxy based on the actual proxy environment.
