Add Nix Flake with derivation, shell, service #940

Open jakubgs opened 2 weeks ago

jakubgs commented 2 weeks ago

It would be helpful to have a Nix flake for this package. The most basic version would just include a build shell, but a a more advanced version would also include a full derivation and also a NixOS service module.

If possible we should also have CI job for our Nix builds.

This was requested by Corey, but Jarrad would also appreciate it.

Here is an attempt by Corey to get something working, some parts of the derivation might be useful: codex-flake.nix.txt

This shell script worked, but it didn't include the CMakeLists.txt patch I had to do: shell.nix.txt

Here's how I updated the CMakeLists.txt file (from Claude.ai):

  1. Open the CMakeLists.txt file in a text editor: nano /home/petty/codex/repos/nim-codex/vendor/nim-leopard/vendor/leopard/CMakeLists.txt

  2. replace the else block (just before the add_library command), add the following:

    else()
check_cxx_compiler_flag("-march=native" CXX_FLAG_MARCH_NATIVE)
check_cxx_compiler_flag("-mtune=native" CXX_FLAG_MTUNE_NATIVE)
check_cxx_compiler_flag("-msse" CXX_FLAG_SSE)
check_cxx_compiler_flag("-msse2" CXX_FLAG_SSE2)
check_cxx_compiler_flag("-msse3" CXX_FLAG_SSE3)
check_cxx_compiler_flag("-mssse3" CXX_FLAG_SSSE3)
check_cxx_compiler_flag("-msse4.1" CXX_FLAG_SSE41)
check_cxx_compiler_flag("-msse4.2" CXX_FLAG_SSE42)
check_cxx_compiler_flag("-mavx" CXX_FLAG_AVX)
check_cxx_compiler_flag("-mavx2" CXX_FLAG_AVX2)

if(CXX_FLAG_MARCH_NATIVE)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -march=native")
endif()
if(CXX_FLAG_MTUNE_NATIVE)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mtune=native")
endif()
if(CXX_FLAG_SSE)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -msse")
endif()
if(CXX_FLAG_SSE2)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -msse2")
endif()
if(CXX_FLAG_SSE3)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -msse3")
endif()
if(CXX_FLAG_SSSE3)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mssse3")
endif()
if(CXX_FLAG_SSE41)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -msse4.1")
endif()
if(CXX_FLAG_SSE42)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -msse4.2")
endif()
if(CXX_FLAG_AVX)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mavx")
endif()
if(CXX_FLAG_AVX2)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mavx2")
endif()

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Wextra -Werror")
endif()
