Install instructions

To install or develop the Solri version of Urbit, you need to build it from source.

Build instructions

External dependencies

vere, the Urbit virtual machine, depends on the following:

• C compiler (gcc or clang)
• GNU Make
• GMP
• CMake
• automake, autoconf, and libtool
• OpenSSL
• libsigsegv
• libcurl
• curses implementation (ncurses on Linux distributions, OS curses otherwise)
• Ragel
• re2c

Most of these dependencies are unfortunate; we aim to drastically shrink the list in upcoming versions. vere proper makes use of GMP, OpenSSL, libcurl, and libsigsegv. The multiple build tools are a result of bundled libraries, slated for future unbundling or removal wherever possible.

Building

Our Makefile should handle the build smoothly on all supported platforms. It's just a simple Makefile, written by hand for GNU Make, and the most complicated parts of its internal machinery have to do with the varied build systems of the bundled libraries.

Useful targets are the default all, clean, and distclean. The last may not produce an entirely clean distribution directory, and runs a bundled library's configure script; git clean may be a better option.

The vere binary is produced in bin/urbit.

Building the Debian Package

To build a .deb file for installation on Debian platforms, perform the following steps:

• Run sudo apt install devscripts to install the debuild utility.
• Update the debian/changelog to reflect the changes in this release.
• If necessary, update the year of the copyright in debian/copyright.
• Clean any build artifacts: Run make clean and delete the bin directory, if it exists.
• Run tar -xcvf ../urbit-x.y.z.orig.tar.gz . from the top-level folder in the repo. This command will create an archive in the directory above the current directory, which will be used in packaging.
• Run debuild -us -uc, also from the top-level folder in the repo. This creates a .deb file in the folder above the current directory.

The resulting .deb file should now exist in the folder above the current directory. To test that the .deb file works properly, you can perform the following steps:

• Uninstall urbit: sudo apt remove urbit.
• Run sudo dpkg -i ../urbit-x.y.z_amd64.deb to install the new version.
• Boot up a ship using the urbit command.
