Hi Çagdas,

The scripts are still very experimental and need some manual handholding quite regularly (mainly because running 4000 simultaneous Docker containers still triggers some data corruption in the filesystem backends in use and destroys the humble SSDs with all the disk I/O).  That's why the /builds URL is not linked from the main opam.ocaml.org page yet.

In the meanwhile though, you can in theory recreate the builds (albeit slowly) by running this on a host with a recent Docker installed:

    opam install -y cmdliner cow git core_kernel
    git clone git://github.com/avsm/ocaml-docker-scripts
    cd ocaml-docker-scripts/bulk-builds
    <edit cron.sh to set JOBS to a reasonable parallel build value>
    ./cron.sh

This will do a single bulk build of all the OS variants and output HTML into logs/

Even more useful would be to keep an eye on https://opam.ocaml.org/builds and submit pull requests to fix the failing packages :-)

cheers,
Anil
