Follow the guidelines below for building Electron on Linux.
At least 25GB disk space and 8GB RAM.
Python 2.7.x. Some distributions like CentOS 6.x still use Python 2.6.x so you may need to check your Python version with python -V.
Please also ensure that your system and Python version support at least TLS 1.2. For a quick test, run the following script:
$ python ./script/tls.py
If the script returns that your configuration is using an outdated security protocol, use your system's package manager to update Python to the latest version in the 2.7.x branch. Alternatively, visit https://www.python.org/downloads/ for detailed instructions.
Node.js. There are various ways to install Node. You can download source code from nodejs.org and compile it. Doing so permits installing Node on your own home directory as a standard user. Or try repositories such as NodeSource.
clang 3.4 or later.
Development headers of GTK+ and libnotify.
On Ubuntu, install the following libraries:
$ sudo apt-get install build-essential clang libdbus-1-dev libgtk-3-dev \
libnotify-dev libgnome-keyring-dev libgconf2-dev \
libasound2-dev libcap-dev libcups2-dev libxtst-dev \
libxss1 libnss3-dev gcc-multilib g++-multilib curl \
gperf bison On RHEL / CentOS, install the following libraries:
$ sudo yum install clang dbus-devel gtk3-devel libnotify-devel \
libgnome-keyring-devel xorg-x11-server-utils libcap-devel \
cups-devel libXtst-devel alsa-lib-devel libXrandr-devel \
GConf2-devel nss-devel On Fedora, install the following libraries:
$ sudo dnf install clang dbus-devel gtk3-devel libnotify-devel \
libgnome-keyring-devel xorg-x11-server-utils libcap-devel \
cups-devel libXtst-devel alsa-lib-devel libXrandr-devel \
GConf2-devel nss-devel Other distributions may offer similar packages for installation via package managers such as pacman. Or one can compile from source code.
$ git clone https://github.com/electron/electron
The bootstrap script will download all necessary build dependencies and create the build project files. You must have Python 2.7.x for the script to succeed. Downloading certain files can take a long time. Notice that we are using ninja to build Electron so there is no Makefile generated.
$ cd electron $ ./script/bootstrap.py --verbose
If you are using editor supports JSON compilation database based language server, you can generate it:
$ ./script/build.py --compdb
If you want to build for an arm target you should also install the following dependencies:
$ sudo apt-get install libc6-dev-armhf-cross linux-libc-dev-armhf-cross \
g++-arm-linux-gnueabihf Similarly for arm64, install the following:
$ sudo apt-get install libc6-dev-arm64-cross linux-libc-dev-arm64-cross \
g++-aarch64-linux-gnu And to cross-compile for arm or ia32 targets, you should pass the --target_arch parameter to the bootstrap.py script:
$ ./script/bootstrap.py -v --target_arch=arm
If you would like to build both Release and Debug targets:
$ ./script/build.py
This script will cause a very large Electron executable to be placed in the directory out/R. The file size is in excess of 1.3 gigabytes. This happens because the Release target binary contains debugging symbols. To reduce the file size, run the create-dist.py script:
$ ./script/create-dist.py
This will put a working distribution with much smaller file sizes in the dist directory. After running the create-dist.py script, you may want to remove the 1.3+ gigabyte binary which is still in out/R.
You can also build the Debug target only:
$ ./script/build.py -c D
After building is done, you can find the electron debug binary under out/D.
To clean the build files:
$ npm run clean
To clean only out and dist directories:
$ npm run clean-build
Note: Both clean commands require running bootstrap again before building.
Prebuilt clang will try to link to libtinfo.so.5. Depending on the host architecture, symlink to appropriate libncurses:
$ sudo ln -s /usr/lib/libncurses.so.5 /usr/lib/libtinfo.so.5
See Build System Overview: Tests
The default building configuration is targeted for major desktop Linux distributions. To build for a specific distribution or device, the following information may help you.
libchromiumcontent locallyTo avoid using the prebuilt binaries of libchromiumcontent, you can build libchromiumcontent locally. To do so, follow these steps:
$ git submodule update --init --recursive
--build_release_libcc switch to bootstrap.py script:$ ./script/bootstrap.py -v --build_release_libcc
Note that by default the shared_library configuration is not built, so you can only build Release version of Electron if you use this mode:
$ ./script/build.py -c R
clang instead of downloaded clang binariesBy default Electron is built with prebuilt clang binaries provided by the Chromium project. If for some reason you want to build with the clang installed in your system, you can call bootstrap.py with --clang_dir=<path> switch. By passing it the build script will assume the clang binaries reside in <path>/bin/.
For example if you installed clang under /user/local/bin/clang:
$ ./script/bootstrap.py -v --build_release_libcc --clang_dir /usr/local $ ./script/build.py -c R
clang
To build Electron with compilers like g++, you first need to disable clang with --disable_clang switch first, and then set CC and CXX environment variables to the ones you want.
For example building with GCC toolchain:
$ env CC=gcc CXX=g++ ./script/bootstrap.py -v --build_release_libcc --disable_clang $ ./script/build.py -c R
Apart from CC and CXX, you can also set the following environment variables to customise the build configuration:
CPPFLAGSCPPFLAGS_hostCFLAGSCFLAGS_hostCXXFLAGSCXXFLAGS_hostARAR_hostCCCC_hostCXXCXX_hostLDFLAGSThe environment variables have to be set when executing the bootstrap.py script, it won't work in the build.py script.
