Compilation

This document focuses on how to code Doris through source code.

Developing mirror compilation using Docker (recommended)

Use off-the-shelf mirrors

1. Download Docker Mirror

   $ docker pull apache/doris:build-env-ldb-toolchain-latest

   Check mirror download completed:

   $ docker images
   REPOSITORY               TAG                              IMAGE ID            CREATED             SIZE
   apache/doris   build-env-ldb-toolchain-latest   49f68cecbc1a        4 days ago          3.76GB

Note1: For different versions of Doris, you need to download the corresponding mirror version. From Apache Doris 0.15 version, the docker image will keep same version number with Doris. For example, you can use apache/doris:build-env-for-0.15.0 to compile Apache Doris 0.15.0.

Node2: apache/doris:build-env-ldb-toolchain-latest is for compiling trunk code, and will be updated along with trunk code. View the update time in docker/README.md

note:

1. Third-party libraries in images with no-avx2 in their names that can run on CPUs that do not support avx2 instructions. Doris can be compiled with the USE_AVX2=0 option.

2. Dev docker image ChangeLog

3. Doris version 0.14.0 still uses apache/incubator-doris:build-env-1.2 to compile, and the 0.14.x code will use apache/incubator-doris:build-env-1.3.1.

4. Since the docker image of build-env-1.3.1 includes both OpenJDK 8 and OpenJDK 11, please confirm the default JDK version with java -version. You can also switch versions in the following ways (it is recommended to use JDK8 by default)

   Switch to JDK 8:

   alternatives --set java java-1.8.0-openjdk.x86_64
   alternatives --set javac java-1.8.0-openjdk.x86_64
   export JAVA_HOME=/usr/lib/jvm/java-1.8.0

   Switch to JDK 11:

   alternatives --set java java-11-openjdk.x86_64
   alternatives --set javac java-11-openjdk.x86_64
   export JAVA_HOME=/usr/lib/jvm/java-11

1. Running Mirror

   $ docker run -it apache/doris:build-env-ldb-toolchain-latest

   It is recommended to run the container by mounting the local Doris source directory, so that the compiled binary file will be stored in the host machine and will not disappear because the container exits.

   At the same time, it is recommended to mount the maven .m2 directory in the mirror to the host directory at the same time to prevent repeated downloading of maven’s dependent libraries each time the compilation is started.

   $ docker run -it -v /your/local/.m2:/root/.m2 -v /your/local/doris-DORIS-x.x.x-release/:/root/doris-DORIS-x.x.x-release/ apache/doris:build-env-ldb-toolchain-latest

2. Download source code

   After starting the mirror, you should be in the container. The Doris source code can be downloaded from the following command (local source directory mounted is not required):

   $ wget https://dist.apache.org/repos/dist/dev/doris/xxx.tar.gz
   or
   $ git clone https://github.com/apache/doris.git

3. Compile Doris

   First run the following command to check whether the compilation machine supports the avx2 instruction set

   $ cat /proc/cpuinfo | grep avx2

   If it is not supported, use the following command to compile

   $ USE_AVX2=0 sh build.sh

   If supported, compile directly without adding USE_AVX2=0

   $ sh build.sh

   After compilation, the output files are in the output/ directory.

   Note:

   If you are using build-env-for-0.15.0 or later version for the first time, use the following command when compiling:

   sh build.sh --clean --be --fe --ui

   This is because from build-env-for-0.15.0, we upgraded thrift (0.9 -> 0.13), you need to use the —clean command to force the use of the new version of thrift to generate code files, otherwise incompatible code will appear.

   After compilation, the output file is in the output/ directory.

Self-compiling Development Environment Mirror

You can also create a Doris development environment mirror yourself, referring specifically to the docker/README.md file.

Direct Compilation (Ubuntu)

You can try to compile Doris directly in your own Linux environment.

1. System Dependence

   • Before commit ad67dd3 will use the dependencies as follows:

     GCC 7.3+, Oracle JDK 1.8+, Python 2.7+, Apache Maven 3.5+, CMake 3.11+ Bison 3.0+

     If you are using Ubuntu 16.04 or newer, you can use the following command to install the dependencies

     sudo apt-get install build-essential openjdk-8-jdk maven byacc flex automake libtool-bin bison binutils-dev libiberty-dev zip unzip libncurses5-dev curl git ninja-build python autopoint pkg-config
     apt-add-repository 'deb https://apt.kitware.com/ubuntu/ focal main'
     apt-get update && apt-get install cmake

     If you are using CentOS you can use the following command to install the dependencies

     sudo yum groupinstall 'Development Tools' && sudo yum install maven cmake byacc flex automake libtool bison binutils-devel zip unzip ncurses-devel curl git wget python2 glibc-static libstdc++-static java-1.8.0-openjdk

   • After commit ad67dd3 will use the dependencies as follows:

     GCC 10+, Oracle JDK 1.8+, Python 2.7+, Apache Maven 3.5+, CMake 3.19.2+ Bison 3.0+

     If you are using Ubuntu 16.04 or newer, you can use the following command to install the dependencies

     ln -s /usr/bin/gcc-11 /usr/bin/gcc
     sudo apt-get install autoconf automake libtool autopoint

2. Compile Doris

   Compiling with the Docker development image, check whether the avx2 instruction is supported before compiling

   $ cat /proc/cpuinfo | grep avx2

   If supported, use the following command to compile

   $ sh build.sh

   If it is not supported, you need to add USE_AVX2=0

   $ USE_AVX2=0 sh build.sh

   After compilation, the output files are in the output/ directory.

FAQ

1. Could not transfer artifact net.sourceforge.czt.dev:cup-maven-plugin:pom:1.6-cdh from/to xxx

   If you encounter the above error, please refer to PR #4769 to modify the cloudera-related repo configuration in fe/pom.xml.

2. The third party relies on download connection errors, failures, etc.

   The download links of the third-party libraries that Doris relies on are all in the thirdparty/vars.sh file. Over time, some download connections may fail. If you encounter this situation. It can be solved in the following two ways:

   1. Manually modify the thirdparty/vars.sh file

      Manually modify the problematic download connection and the corresponding MD5 value.

   2. Use a third-party download warehouse:

      export REPOSITORY_URL=https://doris-thirdparty-repo.bj.bcebos.com/thirdparty
      sh build-thirdparty.sh

      REPOSITORY_URL contains all third-party library source code packages and their historical versions.

Special statement

Starting from version 0.13, the dependency on the two third-party libraries [1] and [2] will be removed in the default compiled output. These two third-party libraries are under GNU General Public License V3. This license is incompatible with Apache License 2.0, so it should not appear in the Apache release by default.

Remove library [1] will result in the inability to access MySQL external tables. The feature of accessing MySQL external tables will be implemented through UnixODBC in future release version.

Remove library [2] will cause some data written in earlier versions (before version 0.8) to be unable to read. Because the data in the earlier version was compressed using the LZO algorithm, in later versions, it has been changed to the LZ4 compression algorithm. We will provide tools to detect and convert this part of the data in the future.

If required, users can continue to use these two dependent libraries. If you want to use it, you need to add the following options when compiling:

WITH_MYSQL=1 WITH_LZO=1 sh build.sh

Note that when users rely on these two third-party libraries, Doris is not used under the Apache License 2.0 by default. Please pay attention to the GPL related agreements.

• [2] lzo-2.10
