This project gives you:
- "`compilers`" workflow scripts to build and automatically create releases of OCaml native executables
Other types of workflow scripts may be added in the future.
In contrast to the conventional [setup-ocaml](https://github.com/marketplace/actions/set-up-ocaml) GitHub Action:
| `compilers` | `setup-ocaml` | Consequence |
| ------------------------------------ | ------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| dkml-base-compiler | ocaml-base-compiler | `compilers` **only supports 4.14.2 today**. `setup-ocaml` supports all versions and variants of OCaml including OCaml 5 |
| GitHub Local Action | GitHub Marketplace Action | `compilers` uses local scripts to implement the GitHub build logic, while `setup-ocaml` is distributed through GitHub Marketplace which is easier to use |
| GitLab CI/CD Local Include | *not supported* | `compilers` supports GitLab CI/CD |
| Personal Computer Scripts | *not supported* | `compilers` can generates scripts to simulate CI on your personal computer for troubleshooting |
| MSVC + MSYS2 | GCC + Cygwin | On Windows `compilers` can let your native code use ordinary Windows libraries without ABI conflicts. You can also distribute your executables without the license headache of redistributing or statically linking `libgcc_s_seh` and `libstdc++` |
| dkml-base-compiler | ocaml-base-compiler | On macOS, `compilers` cross-compiles to ARM64 with `dune -x darwin_arm64` |
| CentOS 7 and Linux distros from 2014 | Latest Ubuntu | On Linux, `compilers` builds with an old GLIBC. `compilers` dynamically linked Linux executables will be highly portable as GLIBC compatibility issues should be rare, and compatible with the unmodified LGPL license used by common OCaml dependencies like [GNU MP](https://gmplib.org/manual/Copying) |
| 1 yrs | 4 yrs | `setup-ocaml` is officially supported and well-tested. |
| Some pinned packages | No packages pinned | `compilers`, for some packages, must pin the version so that cross-platform patches (especially for Windows) are available. With `setup-ocaml` you are free to use any version of any package |
| diskuv/diskuv-opam-repository | fdopen/opam-repository | Custom patches for Windows are sometimes needed. `compilers` uses a much smaller set of patches. `setup-ocaml` uses a large but deprecated set of patches. |
> Put simply, use the `compilers` workflows when you are distributing executables or libraries to the public. Use `setup-ocaml` for all other needs.
The `compilers` workflows will setup the following OCaml build environments for you:
| ABIs | Native `ocamlopt` compiler supports building executables for the following operating systems: |
| ---------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------- |
| `win32-windows_x86` | 32-bit Windows [1] for Intel/AMD CPUs |
| `win32-windows_x86_64` | 64-bit Windows [1] for Intel/AMD CPUs |
| `macos-darwin_all` | 64-bit macOS for Intel and Apple Silicon CPUs. Using `dune -x darwin_arm64` will cross-compile [2] to both; otherwise defaults to Intel. |
| `manylinux2014-linux_x86` | 32-bit Linux: CentOS 7, CentOS 8, Fedora 32+, Mageia 8+, openSUSE 15.3+, Photon OS 4.0+ (3.0+ with updates), Ubuntu 20.04+ |
| `manylinux2014-linux_x86_64` | 64-bit Linux: CentOS 7, CentOS 8, Fedora 32+, Mageia 8+, openSUSE 15.3+, Photon OS 4.0+ (3.0+ with updates), Ubuntu 20.04+ |
> **[1]** See [Distributing your Windows executables](#distributing-your-windows-executables) for further details
>
> **[2]** Cross-compiling typically requires that you use Dune to build all your OCaml package dependencies.
> [opam monorepo](https://github.com/ocamllabs/opam-monorepo#readme) makes it easy to do exactly that.
> Alternatively you can directly use [findlib toolchains](http://projects.camlcity.org/projects/dl/findlib-1.9.3/doc/ref-html/r865.html).

## Configure your project
FIRST, let's ensure you have a `./dk` in your project ...
- On Windows **PowerShell**, macOS and desktop Linux:
```sh
git clone https://gitlab.com/diskuv/dktool.git
dktool/dk user.dkml.wrapper.upgrade HERE
./dk dkml.wrapper.upgrade DONE
```
- Or in Windows **Command Prompt**:
```dosbatch
git clone https://gitlab.com/diskuv/dktool.git
dktool\dk user.dkml.wrapper.upgrade HERE
.\dk dkml.wrapper.upgrade DONE
```
SECOND, create the scaffolding files with **one** of the following options ...
```sh
# FYI: You can get help to see what will happen with:
# ./dk dkml.workflow.compilers HELP
# If you want GitHub scripts
./dk dkml.workflow.compilers CI GitHub
# If you want GitHub scripts, but only for Windows CI
./dk dkml.workflow.compilers CI GitHub OS Windows
# If you want just GitLab script
./dk dkml.workflow.compilers CI GitLab
```
and then commit the new files that were created ....
```sh
git add -A
git update-index --chmod=+x ./dk ci/build-test.sh
git commit -m "ci: DkML compilers"
```
### `ci/build-test.sh`
The `./dk dkml.workflow.compilers ...` command will have created a `ci/build-test.sh` POSIX shell script for you if it wasn't present already.
Your build logic will be inside the `ci/build-test.sh` script. This will work even on Windows; just be careful on Windows that you save the shell script with **LF line endings (not CRLF), and use UTF-8 encoding**.
The [Examples](#examples) section has comprehensive examples.
*The script does not need to be named `ci/build-test.sh`. However the documentation and the auto-generated scripts (which you can change) assumes that filename.*

## Using the GitLab CI/CD backend
> macOS runners are not available in the GitLab CI/CD shared fleet unless
> you apply and are approved at
> . More details are
> available at
>
> This documentation assumes you have not been approved. Look inside .gitlab-ci.yml
> and uncomment the macos:build section once you have been approved for macOS.
The [Examples](#examples) include more features, like the uploading and releasing of your built artifacts.
## Using the GitHub Actions backend
The [Examples](#examples) include more features, like the uploading and releasing of your built artifacts.
## Using the Personal Computer backend
This backend is meant for troubleshooting when a GitLab CI/CD or GitHub Actions
backend fails to build your code. You can do the build locally!
> Tip: The Linux backend can be run from macOS and Windows PCs because it
> uses Docker.
### Windows backend
On Windows in PowerShell run:
```powershell
./dk dkml.workflow.compilers CI Desktop OS Windows
& .ci\dkml-compilers\pc\setup-dkml-windows_x86_64.ps1
```
You can use `& .ci\dkml-compilers\pc\setup-dkml-windows_x86.ps1` for 32-bit Windows
builds.
After running the `.ps1` script you will see instructions for running
Opam commands in your PowerShell terminal.
To see all of the advanced options that can be set, use:
```powershell
get-help .ci\dkml-compilers\pc\setup-dkml-windows_x86_64.ps1 -Full
```
See [Advanced Usage: Job Inputs](#job-inputs) for some of the advanced options that
can be set.
### macOS backend
Run:
```bash
./dk dkml.workflow.compilers CI Desktop OS Darwin
# PICK EITHER:
# macOS/Intel (or macOS/ARM64 with Rosetta emulator)
sh .ci/dkml-compilers/pc/setup-dkml-darwin_x86_64.sh
# -OR- macOS/ARM64
sh .ci/dkml-compilers/pc/setup-dkml-darwin_arm64.sh
```
To see all of the advanced options that can be set, use:
```powershell
sh .ci/dkml-compilers/pc/setup-dkml-darwin_arm64.sh -h
```
See [Advanced Usage: Job Inputs](#job-inputs) for some of the advanced options that
can be set.
### Linux backends
Run one of:
```bash
./dk dkml.workflow.compilers CI Desktop OS Linux
# PICK EITHER:
# Linux on 64-bit Intel/AMD. Docker is required.
# - Running this from macOS/Intel with Docker or macOS/Silicon with Docker will also work
# - Running this using with-dkml.exe on Windows with Docker will also work
# (the normal Linux containers host, not the Windows containers host). The
# easiest is using 'with-dkml sh ...' if you have DkML. You can also
# download MSYS2 from https://www.msys2.org/#installation, or Cygwin, and then
# run MSYS2 or Cygwin, but you must make sure that 'docker' is in your PATH
# (ex. export PATH='/c/Program Files/Docker/Docker/resources/bin':"$PATH").
sh .ci/dkml-compilers/pc/setup-dkml-linux_x86_64.sh
# -OR-
# Linux on 32-bit Intel/AMD. Docker is required.
# - Running this from macOS/Intel should also work (not tested). macOS/Silicon will not work.
# - Running this on Windows should also work using the same guidance as
# on Linux 64-bit. Has not been tested
sh .ci/dkml-compilers/pc/setup-dkml-linux_x86.sh
```
To see all of the advanced options that can be set, use:
```powershell
sh .ci/dkml-compilers/pc/setup-dkml-linux_x86_64.sh -h
```
See [Advanced Usage: Job Inputs](#job-inputs) for some of the advanced options that
can be set.
## Distributing your executable
### Distributing your Windows executables
Since your executable has been compiled with the Microsoft Visual Studio
Compiler (MSVC), your executable will require that the Visual Studio
Runtime (`vcruntime140.dll`) is available on your end-user's machine.
If your end-user recently purchased a Windows machine the Visual C++ Redistributable
will not be present; they would see the following if they tried to run your
executable:
`vcruntime140.dll` and other DLLs that are linked into your executable
by Visual Studio are available as part of the
[Visual C++ Redistributable Packages](https://docs.microsoft.com/en-us/cpp/windows/redistributing-visual-cpp-files).
As of April 2022 the Redistributable Packages only support Windows Vista, 7,
8.1, 10, and 11. Windows XP is **not** supported.
To get the Redistributable Packages onto your end-user's
machine, do one of the following:
1. Ask your end-user to download from one of the links on [Microsoft Visual C++ Redistributable latest supported downloads](https://docs.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist). The end-user will need Administrator privileges.
2. Bundle your executable inside a standard Windows installer (NSIS, Wix, etc.). You can see NSIS instructions below. The end-user will need Administrator privileges.
3. Ask your user to download `vcruntime140.dll` and place it in the same
directory as your executable. This is not recommended because Windows Update
will not be able to apply any security updates to your locally deployed
`vcruntime140.dll`.
---
If you choose option 2 and are using NSIS as your Windows installer, you can add
the following NSIS section to your NSIS configuration:
```nsis
Section "Visual C++ Redistributable Packages"
SetOutPath "$INSTDIR"
!include "x64.nsh"
${If} ${IsNativeAMD64}
File "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Redist\MSVC\14.29.30133\vc_redist.x64.exe"
ExecWait '"$INSTDIR\vc_redist.x64.exe" /install /passive'
Delete "$INSTDIR\vc_redist.x64.exe"
${ElseIf} ${IsNativeARM64}
File "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Redist\MSVC\14.29.30133\vc_redist.arm64.exe"
ExecWait '"$INSTDIR\vc_redist.arm64.exe" /install /passive'
Delete "$INSTDIR\vc_redist.arm64.exe"
${ElseIf} ${IsNativeIA32}
File "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Redist\MSVC\14.29.30133\vc_redist.x86.exe"
ExecWait '"$INSTDIR\vc_redist.x86.exe" /install /passive'
Delete "$INSTDIR\vc_redist.x86.exe"
${Else}
Abort "Unsupported CPU architecture!"
${EndIf}
SectionEnd
```
When you run the `makensis.exe` NSIS compiler the specified `File` must be
present on the `makensis.exe` machine. Make sure you have set it correctly!
If the NSIS compiler is running
as part of the GitHub Actions, you can
look at the output of setup-dkml.yml's step
"Capture Visual Studio compiler environment (2/2)"; the directory will be
the `VCToolsRedistDir` environment variable. The `VCToolsRedistDir` environment
variable will also be available to use as
`opamrun exec -- sh -c 'echo $VCToolsRedistDir'`
## Advanced Usage
### Job Inputs
#### SKIP_OPAM_MODIFICATIONS
When set to `true` (the default is `false`) the opam root will not be
created or modified. Setting `dkml_target_abi` is no longer required.
The `cmdrun` script will be available for you to create your
own opam root and switches. The commands you run will have access to
the correct `OPAMROOT` environment variable for the platform, and a proper
MSVC environment on Windows, and run within a working dockcross container
for Linux.
The `opamrun` script will still be available, but it should only be used if
you have already initialized (created) the opam root.
#### SECONDARY_SWITCH
When set to `true` the scripts will CI jobs will create the `two` switch in addition to the always present `dkml` switch.
When using the secondary switch, be sure to use `--switch dkml` or `--switch two` in *all* of your `opamrun` commands.
For example, use `opamrun install --switch dkml dune` rather than `opamrun install dune`.
#### CACHE_PREFIX
The prefix of the cache keys.
#### PRIMARY_SWITCH_SKIP_INSTALL
When set to `true` no dkml-base-compiler will be installed in the `dkml` switch.
### Matrix Variables
#### gl_image
The GitLab virtual machine image for macOS. Examples: `macos-11-xcode-12`.
Linux always uses a [Docker-in-Docker image](https://docs.gitlab.com/ee/ci/docker/using_docker_build.html#use-docker-in-docker).
#### gh_os
The GitHub Actions operating system.
#### opam_root
OPAMROOT must be a subdirectory of GITHUB_WORKSPACE if running in
dockcross so that the Opam root (and switch) is visible in both the
parent and Docker context. Always specify this form as a relative
path under GITHUB_WORKSPACE.
When not using dockcross, it should be an absolute path to a
directory with a short length to minimize the 260 character
limit on Windows (macOS/XCode also has some small limit).
CAUTION: The opam_root MUST be in sync with outputs.import_func!
#### vsstudio_hostarch
Only needed if `gh_os: windows-*`. The ARCH in
`vsdevcmd.bat -host_arch=ARCH`. Example: x64.
If you have a 64-bit Intel machine you should not use x86 because
_WIN64 will be defined (see )
which is based on the host machine architecture (unless you explicitly
cross-compile with different ARCHs; that is, -host_arch=x64 -arch=x75).
Confer:
If you see ppx problems with missing _BitScanForward64 then
has been compiled with the wrong host architecture.
#### vsstudio_arch
Only needed if `gh_os: windows-*`. The ARCH in
`vsdevcmd.bat -arch=ARCH`. Example: x86.
Confer:
#### vsstudio_(others)
Hardcodes details about Visual Studio rather than let DkML discover
a compatible Visual Studio installation.
Example:
```yaml
vsstudio_dir: 'C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise'
vsstudio_vcvarsver: '14.16'
vsstudio_winsdkver: '10.0.18362.0'
vsstudio_msvspreference: 'VS16.5'
vsstudio_cmakegenerator: 'Visual Studio 16 2019'
```
#### ocaml_options
Space separated list of `ocaml-option-*` packages.
Use 32-bit installers when possible for maximum portability of
OCaml bytecode. Linux has difficulty with 32-bit (needs gcc-multilib, etc.)
macos is only the major platform without 32-bit.
You don't need to include `ocaml-option-32bit` because it is auto
chosen when the target ABI ends with x86.
