# You generally should not modify this.
# TODO(cleanup): -fPIC is unfortunate since most of our code is static binaries
#   but we also need to build a .node module which is a shared library, and it
#   needs to include all the Cap'n Proto code. Do we double-compile or do we
#   just accept it? Perhaps it's for the best since we probably should build
#   position-independent executables for security reasons?
# NOTE: Emperically -DKJ_STD_COMPAT appears to be necessary on recent ditros
#   (as of Jan 2020), notably Debian Sid, Fedora 30 and Archlinux. We're not
#   entirely sure what changed, but this seems like a backwards incompatibility
#   in libstdc++. See also issue #3171.

# Get Clang

# We use the prebuilt Clang binaries from the Chromium project. We do this because I've observed
# Sandstorm contributors have a very hard time installing up-to-date versions of Clang on typcial
# Linux distros. Ubuntu and Debian ship with outdated versions of Clang, which means people have
# to install Clang from the LLVM apt repo. However, people struggle to set that up, and the repo
# has been known to randomly break from time to time. OTOH, the Chromium project maintains a very
# up-to-date version of Clang which is used to build Chrome, conveniently maintained as a git repo
# (which we can pin to a commit) containing a nice script that will download precompiled binaries.
