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

Most of these dependencies are unfortunate; we aim to drastically shrink the
|
2016-10-06 01:10:37 +03:00
|
|
|
list in upcoming versions. `vere` proper makes use of GMP, OpenSSL, libcurl, and
|
2016-09-12 22:29:35 +03:00
|
|
|
libsigsegv. The multiple build tools are a result of bundled libraries, slated
|
|
|
|
|
for future unbundling or removal wherever possible.

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`.
