v1.0.1 (2024-12-17)

  • allow findlib/dune use libraries available from OPAM (@dinosaure #144)
  • Ignore pthread_cond_destroy (@dinosaure #144)
  • README: fixes (@shym #145)
  • opam: add missing depopt (@hannesm 52c9f8d20d9d80dc51e416cc67d03b80dce257af)

v1.0.0 (2024-12-04)

  • Support for OCaml 5.2.1 (#134 @dinosaure @haesbaert @shym @palainp @kit-ty-kate)

v0.8.5 (2024-12-04)

  • use ocamlfind instead of opam to discover ocaml-src (@hannesm #142)
  • CI fixes (@shym #136, @hannesm #140)
  • Deduplicate example, fix formatting (@shym #137)
  • Update GitHub actions (@smorimoto #138)
  • Fix errors reported by shellcheck (@shym #141)

v0.8.4 (2024-04-23)

  • malloc: fix the memory allocation tracking for posix_memalign (used in mirage-xen via io-page) (#135 @palainp)

v0.8.3 (2024-02-12)

  • Fix the compilation of the OCaml toolchain by specifying the right target value (#128 @dinosaure)

v0.8.2 (2023-11-15)

  • malloc: fix the memory allocation tracking to be precise (fixes #126 reported by @hannesm, #127 @palainp)

v0.8.1 (2022-06-14)

  • malloc: keep track of memory allocation and release (faster than mallinfo, more accurate than footprint) (#120, @winux138 and @palainp)

v0.8.0 (2022-03-27)

  • Rename freestanding to solo5 (#114, #115, @dinosaure, @samoht)
  • Disable build of ocamltest (#108, @hannesm)
  • vfprintf: change long double to double to fix a floating point exception (#110, @palainp)
  • Add conf-which as a dependency (#113, @dinosaure)

v0.7.1 (2022-03-10)

  • remove afl, fp, nnpchecker configure options (#107, @hannesm)
  • Add suppport for OCaml 4.14 (#109, @kit-ty-kate)

v0.7.0 (2022-01-03)

  • NOTE: This release is a part of the MirageOS 4.0 release and, at this stage, ocaml-freestanding.0.7.0 will not continue to support MirageOS 3 unikernels. ocaml-freestanding becomes a real cross-compiler used then by dune (with the cross-compilation option) to compile libraries including C stubs. For the MirageOS 4.0 perspective, libraries which include C stubs does not need anymore to compile multiple times C artifacts depending on what ocaml-freestanding provides. The dune context will help the compilation of these C stubs according the target chosen by the end-user (with the mirage tool).

  • Add compatibility with the solo5 0.7.0 package split. (#104)

  • Build a freestanding cross-compiler to use with the ocamlfind toolchain feature. This cross-compiler is able to build partial executables to link with a solo5 bindings library. (#104)

  • Fix the OpenBSD 7 support (#104)

  • Remove pkg-config (#104)

v0.6.6 (2021-11-15)

  • Fix compilation on alpine 3.13+ with OCaml 4.13+ by providing LDFLAGS including -lopenlibm to OCaml's configure (#99, @dinosaure, fixes #97)

v0.6.5 (2021-09-27)

  • Add support for OCaml 4.13 (#95 #94, @kit-ty-kate @dra27)
  • Remove cflags and libs flags that are no longer used in the MirageOS-with-dune development (#91 @hannesm, reverts #50 @TheLortex). These were introduced in version 0.4.4.

v0.6.4 (2021-03-03)

  • Add support for OCaml 4.12 (#88, @kit-ty-kate)

v0.6.3 (2020-10-12)

  • nolibc: dlmalloc: Improve security posture and robustness by always enabling assertions, initialising magic value for heap canaries using monotonic time and enabling FOOTERs. (#87, @mato)

v0.6.2 (2020-07-22)

  • Fix posix_memalign() return values in failure cases. (#82, @mato)

v0.6.1 (2020-07-21)

  • Add support for Solo5/xen bindings, posix_memalign(). (#81, @mato)
  • nolibc: Implement assert() which was previously a no-op. (#80, @mato)

Downstream OPAM packages with C code that wish to use the interfaces/headers added in this release should depend on ocaml-freestanding { >= 0.6.1 }.

v0.6.0 (2020-05-06)

  • Drop support for OCaml 4.06 and 4.07. (#72, @hannesm)
  • Define an __ocaml_freestanding__ preprocessor macro, undefine leaky host toolchain preprocessor macros (__linux__, __FreeBSD__, __OpenBSD__ et al.), provide an <endian.h>. (#74, @mato)
  • Install all OCaml runtime headers. (#75, @hannesm)
  • Provide a minimal <inttypes.h>. (#76, @mato, fixes #60)
  • Various build system improvements and cleanups. (part of #74, #76, @mato)

Note that #74 may break downstream C code that uses #if...#elif...#endif chains to detect the system it is built on. Such code should be explicitly adapted to detect the presence of ocaml-freestanding by testing for the __ocaml_freestanding__ preprocessor macro.

Further, downstream OPAM packages with C code that wish to use the interfaces/headers added in this release should depend on ocaml-freestanding { >= 0.6.0 }.

  • Add FreeBSD CI using Cirrus CI. (#67, @hannesm)
