From 443cb1ec56d8188f1249ad18656aee6d9dc5021f Mon Sep 17 00:00:00 2001 From: Ihar Hrachyshka Date: Mon, 27 Jan 2025 23:38:40 -0500 Subject: python312Packages.llama-cpp-python: fix linux build Their cmake files were attempting to build with -mcpu=native+no<...> which fails for gcc. Actually, we should never build for native anyway (which is the raison d'etre for NIX_ENFORCE_NO_NATIVE). Thankfully, the package provides a variable to disable native optimizations. --- .../python-modules/llama-cpp-python/default.nix | 15 ++++++++++----- 1 file changed, 10 insertions(+), 5 deletions(-) (limited to 'pkgs/development/python-modules/llama-cpp-python/default.nix') diff --git a/pkgs/development/python-modules/llama-cpp-python/default.nix b/pkgs/development/python-modules/llama-cpp-python/default.nix index 09ee66b8caf0..00dd70400d86 100644 --- a/pkgs/development/python-modules/llama-cpp-python/default.nix +++ b/pkgs/development/python-modules/llama-cpp-python/default.nix @@ -64,7 +64,16 @@ buildPythonPackage rec { dontUseCmakeConfigure = true; SKBUILD_CMAKE_ARGS = lib.strings.concatStringsSep ";" ( - lib.optionals cudaSupport [ + # Set GGML_NATIVE=off.
