Hello. After recent segfault I have re-designed Nix expression building Torch the machine learning framework. New build2.nix doesn't use all-in-one install script from the upstream, but builds one package after another in form of separate derivations. This way turns out to be successful, so we have a Torch which passes the segfault test from the previous letter.
As a side effect, the expression contains function dealing with luarocks (they think every language should have its own package manager))). It would be nice to integrate it into nixpkgs. AFAIK top-level/lua-packages doesn't really support luarocks builds at the moment. To check it out: $ git clone https://github.com/grwlf/torch-distro --recursive $ cd torch-distro $ nix-build build2.nix -A trepl $ ./result/bin/th There are less than a half of the total number of packages. Still many things to do..
