Before you begin, you'll first need to properly configure the Prerequisites as described below.
Then to build, run:
$ ./gradlew build
To publish the artifacts to your Maven local repository for use in your own project, run:
$ ./gradlew publishToMavenLocal
Conscrypt requires that you have Java, BoringSSL and the Android SDK configured as described below.
The build uses a version of Gradle which requires a Java 11 JRE to run, however to ensure backward compatibility Conscrypt itself is compiled with a Java 8 JDK using Gradle's recent Java toolchain support. At the least, you will need to install Java 11 to run Gradle, but if you do not also have Java 8 then depending on the OS, Gradle will try and install it automatically.
Download and install the latest Android SDK and set the ANDROID_HOME
environment variable to point to the root of the SDK (e.g. export ANDROID_HOME=/usr/local/me/Android/Sdk
).
Before you can build BoringSSL, you'll first need to set up its prerequisites.
Once the environment is properly configured, follow the steps below for your platform.
Checkout BoringSSL to a directory of your choice and then build as follows:
git clone https://boringssl.googlesource.com/boringssl cd boringssl # Also need to set an environment variable to point to the installation location. export BORINGSSL_HOME=$PWD
To build the 64-bit version on a 64-bit machine:
mkdir build64 cd build64 cmake -DCMAKE_POSITION_INDEPENDENT_CODE=TRUE \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_ASM_FLAGS=-Wa,--noexecstack \ -GNinja .. ninja
When building Conscrypt on macOS it will build libraries for both x86 and ARM, and so BoringSSL must also be build for each of these.
To build the x86_64 version:
mkdir build.x86 cd build.86 cmake -DCMAKE_POSITION_INDEPENDENT_CODE=TRUE \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_ASM_FLAGS=-Wa,--noexecstack \ -DCMAKE_OSX_ARCHITECTURES=x86_64 \ -GNinja .. ninja
To build the arm64 version:
mkdir build.arm cd build.arm cmake -DCMAKE_POSITION_INDEPENDENT_CODE=TRUE \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_ASM_FLAGS=-Wa,--noexecstack \ -DCMAKE_OSX_ARCHITECTURES=arm64 \ -GNinja .. ninja
This assumes that you have Microsoft Visual Studio 2017 installed along with both the Windows 8.1 and 10 SDKs and that your machine is capable of compiling 64-bit.
Unlike earlier versions, Visual Studio 2017 doesn‘t appear to set an environment variable to simplify building from the command line. The instructions below assume the default installation of the community edition. To use another edition or a non-standard install path, you’ll need to modify the paths below as appropriate.
To build in 64-bit mode, set up with this command line:
call "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat" x86_amd64 mkdir build64 cd build64 cmake -DCMAKE_POSITION_INDEPENDENT_CODE=TRUE ^ -DCMAKE_BUILD_TYPE=Release ^ -DCMAKE_C_FLAGS_RELEASE=/MT ^ -DCMAKE_CXX_FLAGS_RELEASE=/MT ^ -GNinja .. ninja
32-bit mode is no longer supported.
To see coverage numbers, run the tests and then execute the jacocoTestReport rule
./gradlew check jacocoTestReport
The report will be placed in openjdk/build/reports/jacoco/test/html/index.html
