Compiling with LDB toolchain

This document describes how to compile Doris using the LDB toolchain. This method is currently used as a supplement to the Docker compilation method to facilitate developers and users without a Docker environment to compile Doris source code.

You can still compile the latest code using the Docker development image: apache/doris:build-env-ldb-toolchain-latest

Thanks to Amos Bird for this contribution.

Prepare the environment

This works for most Linux distributions (CentOS, Ubuntu, etc.).

  1. Download ldb_toolchain_gen.sh

The latest ldb_toolchain_gen.sh can be downloaded from here. This script is used to generate the ldb toolchain.

For more information, you can visit <https://github.com/amosbird/ldb_toolchain_gen> 2. Execute the following command to generate the ldb toolchain

1. sh ldb_toolchain_gen.sh /path/to/ldb_toolchain/

where /path/to/ldb_toolchain/ is the directory where the toolchain is installed.

After successful execution, the following directory structure will be created under /path/to/ldb_toolchain/.

1. ├── bin 2. ├── include 3. ├── lib 4. ├── share 5. ├── test 6. └── usr 3. Download and install other compiled components

  1. Java8
  2. Apache Maven 3.6.3
  3. Node v12.13.0

If your environment is somehow minimal, additional packages should be installed before compiling Doris. The following instructions describe how to setup a minimal CentOS 6 box to compile Doris. Other linux distros should be similar.

``` 1. # install required system packages 2. sudo yum install -y byacc patch automake libtool make which file ncurses-devel gettext-devel unzip bzip2 zip util-linux wget git python2

  1. install autoconf-2.69

  2. wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz && \
  3. tar zxf autoconf-2.69.tar.gz && \
  4. cd autoconf-2.69 && \
  5. ./configure && \
  6. make && \

  7. make install

  8. install bison-3.0.4

  9. wget http://ftp.gnu.org/gnu/bison/bison-3.0.4.tar.gz && \
  10. tar xzf bison-3.0.4.tar.gz && \
  11. cd bison-3.0.4 && \
  12. ./configure && \
  13. make && \
  14. make install ```
  15. Download Doris source code

1. git clone https://github.com/apache/doris.git

After downloading, go to the Doris source directory, create the custom_env.sh, file, and set the PATH environment variable, e.g.

1. export JAVA_HOME=/path/to/java/ 2. export PATH=$JAVA_HOME/bin:$PATH 3. export PATH=/path/to/maven/bin:$PATH 4. export PATH=/path/to/node/bin:$PATH 5. export PATH=/path/to/ldb_toolchain/bin:$PATH

Compiling Doris

Enter the Doris source code directory and execute:

1. $ cat /proc/cpuinfo | grep avx2

Check whether the compilation machine supports the avx2 instruction set

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

1. $ USE_AVX2=0 sh build.sh

If supported, execute sh build.sh directly

This script will compile the third-party libraries first and then the Doris components (FE, BE) later. The compiled output is in the output/ directory.
