# Initially I wanted to build a slim image using this Dockerfile and static linking.
|
||||
# It would use something like this in Cargo.toml:
|
||||
#
|
||||
# [build-dependencies.clang]
|
||||
# version = "2.0.0"
|
||||
# default-features = false
|
||||
# features = ["static"]
|
||||
#
|
||||
# [build-dependencies.clang-sys]
|
||||
# version = "1.7.0"
|
||||
# default-features = false
|
||||
# features = ["clang_16_0", "static"]
|
||||
#
|
||||
# But there are a lot of problems with static linking and clang & clang-sys crates:
|
||||
# - https://github.com/KyleMayes/clang-sys/issues/174
|
||||
# - https://github.com/KyleMayes/clang-rs/issues/17
|
||||
# - https://github.com/KyleMayes/clang-sys/issues/148 (this is the one I *like* the most!)
|
||||
#
|
||||
# So, no static linking for now, but I don't wanna erase all this gorgeous Dockerfile code, so... I'll let it linger
|
||||
# in the repo for now.
