From 5cf2869118b1db3ae86e6e234462eadd4e1d098d Mon Sep 17 00:00:00 2001 From: Simon Rainerson Date: Wed, 9 Sep 2020 10:16:52 +0200 Subject: [PATCH] wasmer: enable cranelift backend Since wasmer 0.17 no backends are enabled by default. Backends are now detected using the [makefile](https://github.com/wasmerio/wasmer/blob/master/Makefile). This change enables cranelift as this used to be the old default. At least one backend is needed for the `run` subcommand to work. If we want to replicate the actual logic in the makefile, we would probably want to enable the singlepass and llvm backend as well. However enabling llvm backend introduces a dependency on openssl, so we opted for replicating the old default behavior. --- pkgs/development/interpreters/wasmer/default.nix | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/pkgs/development/interpreters/wasmer/default.nix b/pkgs/development/interpreters/wasmer/default.nix index c620b1686ea6..c036b0808909 100644 --- a/pkgs/development/interpreters/wasmer/default.nix +++ b/pkgs/development/interpreters/wasmer/default.nix @@ -22,6 +22,12 @@ rustPlatform.buildRustPackage rec { nativeBuildInputs = [ cmake pkg-config ]; + # Since wasmer 0.17 no backends are enabled by default.
