Package: ocaml-mingw-w64 Version: 4.01.0~20140328-1+b2 Severity: normal I am trying to produce libraries usable from C with OCaml and to compile them using CMake, for which I created a module that tries to simplify this process [1]. As part of the CMake module for building C libraries with OCaml, I have automated the building of a few combinations of options [2]. Among those combinations, cross-compiling for Windows with currently packaged x86_64-w64-mingw32-ocamlopt and i686-w64-mingw32-ocamlopt is producing some unusable binaries [3] [4]. Using opam-cross-windows [5], with the same C compiler, does not pose the same issue [2].
In order to reproduce the issue you can perform the following steps: git clone https://github.com/giuliopaci/ocaml-cmake.git cd ocaml-cmake mkdir build cd build cmake ../examples/hello_world_lib -DCMAKE_VERBOSE_MAKEFILE=on -DCMAKE_TOOLCHAIN_FILE=../toolchains/Toolchain-mingw32.cmake make wine ./main-libhelloworld-bytecode.exe [1] https://github.com/giuliopaci/ocaml-cmake [2] https://travis-ci.org/giuliopaci/ocaml-cmake/builds/287518762 [3] https://travis-ci.org/giuliopaci/ocaml-cmake/jobs/287518771#L1580 [4] https://travis-ci.org/giuliopaci/ocaml-cmake/jobs/287518772#L1590 [5] https://github.com/ocaml-cross/opam-cross-windows -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.13.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=it_IT.UTF-8, LC_CTYPE=it_IT.UTF-8 (charmap=UTF-8), LANGUAGE=it_IT.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Init: systemd (via /run/systemd/system) Versions of packages ocaml-mingw-w64 depends on: ii ocaml-mingw-w64-i686 4.01.0~20140328-1+b2 ii ocaml-mingw-w64-x86-64 4.01.0~20140328-1+b2 ocaml-mingw-w64 recommends no packages. ocaml-mingw-w64 suggests no packages. -- no debconf information
