Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
Reference: https://gcc.gnu.org/gcc-4.9/porting_to.html ------ Header <cstddef> changes The <cstddef> header was updated for C++11 support and this breaks some libraries which misuse macros meant for internal use by GCC only. For instance with GMP versions up to 5.1.3, you may see: /usr/include/c++/4.9.0/cstddef:51:11: error: ‘::max_align_t’ has not been declared using ::max_align_t; ^ Another possible error is: someheader.h:99:13: error: ‘ptrdiff_t’ does not name a type A workaround until libraries get updated is to include <cstddef> or <stddef.h> before any headers from that library. |

About
Requirements
- C++11 compatible compiler: g++ (version >= 4.8.1), or clang++ (version >= 3.3)
- CMake
- GMP (GNU multiprecision library)
- MPFR (GNU MPFR Library)
- Lua 5.2 or 5.1, or LuaJIT 2.0
- (optional) gperftools
- (optional) Boost (version >= 1.54), we can build Lean using boost::thread instead of std::thread. When using Boost, Lean can modify the thread stack size.
