Package MK and deps for Mingw-w64

⚠️⚠️⚠️: This repository is now unneeded and will be archived because we have found a better solution that involves publishing cross built packages using Homebrew. This simplifies our life.

This repository contains the scripts to compile and package MK and its dependencies for Mingw-w64 systems. Previous versions of this repository (once named script-build-unix) used to support building for all Unix and mobile systems, but now here we only support Mingw-w64.

Note: if you want to build for Windows using Microsoft tooling, use measurement-kit/script-build-windows instead.

Build and package

By following this procedure, you will find tarball packages in the root directory and an updated SHA256SUM file that you should commit.

In addition to Unix essential commands, you'll need:

• GNU autoconf, automake, and libtool
• curl
• make
• patch

Each specific build has additional requirements.

Mingw-w64

We assume that you have installed a mingw-w64 distribution compiled with support for POSIX threads and C++11 threads. The one provided by by Homebrew is the one we generally use.

With mingw-w64 installed, just run:

./build-mingw `./all-deps.sh`
./build-mingw measurement-kit
./package

Publishing packages

Packages are publishes as part of script-build-mingw releases.

Downloading packages

For the download to succeed, you must have committed and pushed the changes to SHA256SUM created by the build step and published the related tarballs in the current release of script-build-mingw.

Then run:

./install <package-name>

Where <package-name> is the name of the package (or packages) that you want to install. For example, a compact way to install MK and all its dependencies for Android is the following:

./install `./all-deps.sh mingw-` mingw-measurement-kit

This will download the related tarball, verify its SHA256 sum and unpack the tarball inside ./MK_DIST. You can use find inside of MK_DIST to understand exactly the structure of the downloaded package.

If you integrate this repository as a subdirectory, and you run install from the parent directory, MK_DIST will be inside the parent directory.

./foo/bar/install mingw-libressl-2.6.4-2
# You will find the package in ./MK_DIST rather than ./foo/bar/MK_DIST

Low-level details

For each package, there is a build script named after the package. Packages may depend on each other. You will clearly see that when reading the package specific build script. Make sure you build them in order.

For each possible cross-compilation, there is a script named cross-<os> that sets the proper environment variables for cross compiling.

There may be small patches that we apply to packages. (Preferrably none but some small patches are better than having to do more difficult stuff.)

We always use make to orchestrate the build. Set and export the MAKEFLAGS environment variable properly if you wish, e.g., to have a parallel build.

Likewise, you can specify CPPFLAGS, CFLAGS, CXXFLAGS and LDFLAGS flags in environment variables, to override the flags that we pass to the compiler. The flags you specify will be appended after the flags we specify, giving you the opportunity to override such flags.
