1 Building Firefox 32-bit On Linux 64-bit 2 ======================================= 3 4 .. note:: 5 6 Unless you really want to target older hardware, you probably 7 want to :ref:`Build Firefox 64-bit <Building Firefox On Linux>` 8 since it is better-supported. 9 10 Before following these 32-bit-Firefox-specific instructions, follow 11 the :ref:`Building Firefox On Linux` instructions to ensure that 12 your machine can do a normal build. 13 14 Instructions for Ubuntu 19.10 15 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 16 17 These steps were verified to work as of June 2020. 18 19 #. Run ``rustup target install i686-unknown-linux-gnu`` to install the 20 32-bit Rust target. 21 #. Install 32-bit dependencies with the following command (this shouldn't try to 22 remove packages. If this is the case, those instructions won't work as-is): 23 24 .. code:: 25 26 sudo apt install gcc-multilib g++-multilib \ 27 libgtk2.0-dev:i386 libgtk-3-dev:i386 libpango1.0-dev:i386 libxt-dev:i386 \ 28 libx11-xcb-dev:i386 libpulse-dev:i386 libdrm-dev:i386 29 30 #. Then, create a ``mozconfig`` file in your Firefox code directory 31 (probably ``firefox``) that looks like the following example: 32 33 .. code:: 34 35 ac_add_options --target=i686 36 37 #. Run ``./mach build``.
