Start at [`leanprover/lp`](https://github.com/leanprover/lp)** — the entry\n\u003e point for the `lp` / `maximize` tactics and the verified LP solver. This repository is one\n\u003e package of that family: the raw SoPlex FFI bindings.\n\nLean 4 FFI bindings for [SoPlex](https://soplex.zib.de/), the linear\nprogramming solver from the SCIP optimization suite.\n\nThis repository contains the direct binding only: the vendored SoPlex\nbuild, the C++ bridge, Lean extern wrappers, marshalling, direct solve\nAPIs, and MPS / LP file I/O. The verified Lean layer lives in\n[`leanprover/lp`](https://github.com/leanprover/lp).\n\n## Build\n\nSystem dependencies:\n\n| Platform | Packages |\n|----------|----------|\n| Linux    | `build-essential cmake libgmp-dev libgmpxx4ldbl libboost-dev` |\n| macOS    | `brew install gmp boost cmake` (plus Xcode Command Line Tools) |\n| Windows  | MSYS2 `mingw-w64-x86_64-{gcc,cmake,ninja,make,gmp,boost}` |\n\n```bash\ngit clone --recurse-submodules https://github.com/leanprover/soplex-ffi\ncd soplex-ffi\nlake exe ffi-check\n```\n\nIf you cloned without submodules, Lake attempts to initialize the\nvendored SoPlex submodule automatically. If that fails, run\n`git submodule update --init --recursive`.\n\n## Layout\n\n```\nSoplexFFI.lean          # direct FFI package entry point\nSoplexFFI/              # thin Lean API, types, and validation\nffi/                    # C++ bridge and C ABI entry points\nvendor/soplex           # vendor submodule (scipopt/soplex, tag v8.0.2)\nlakefile.lean           # Lake package and extern_lib build\n```\n\n## Licence\n\n`SoplexFFI` is licenced under the [Apache License 2.0](./LICENSE),\nmatching SoPlex itself. The compiled binary's GMP runtime dependency\n(LGPL) is linked dynamically by default. SoPlex itself is linked into\nthe Lean shared library from the vendored static archive.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fleanprover%2Fsoplex-ffi","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fleanprover%2Fsoplex-ffi","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fleanprover%2Fsoplex-ffi/lists"}
