- ugly libdir hack

[packages/rust.git] / rust.spec

# TODO
# - consider a rust-std package containing .../rustlib/$target
#   This might allow multilib cross-compilation to work naturally.

# Conditional build:
%bcond_with	bootstrap
%bcond_with	tests		# build without tests

# The channel can be stable, beta, or nightly
%define		channel		stable

# To bootstrap from scratch, set the channel and date from src/stage0.txt
# e.g. 1.10.0 wants rustc: 1.9.0-2016-05-24
# or nightly wants some beta-YYYY-MM-DD
