WIP: Dlib, Torch7, OpenFace

[arrowd]

Summary

This is WIP diff adding ports for

• Dlib C++ library
• Torch7 scientific framework
• OpenFace python library for face detection

There are numerous TODOs, but it started to get too complex, so I wanted to share my work.

Current problems:

• Enable support for various Dlib options
• BLAS support in Dlib doesn't work with default BLAS library (netlib). The problem is subtle, I've notified maintainer about this. At the same time, Torch7 defaults to openblas, so maybe it is better to just use it for Dlib too?
• There is no luajit support in lua.mk. This made me hard code some paths in the makefiles. Moreover, ports like devel/lua-cwrap can also work with lua5*, and I havem't figured out how to handle this case. The upcoming FLAVORS support might fix this, but I'd rather stick to more old-school handling.

I plan to gradually fix issues and extend torch7-* ports, but any help is welcome.

devel/lua-cwrap/Makefile

Default, remove.

devel/lua-penlight/Makefile

17

PORTNAME should be Penlight, and then you can remove this line.

devel/torch7-sys/Makefile

20

Default, remove.

graphics/py-openface/Makefile

21–24

Out of order. See Chapter 14. Order of Variables in Port Makefiles.

science/dlib-cpp/Makefile

14–18

Out of order. See Chapter 14. Order of Variables in Port Makefiles.

science/py-dlib/Makefile

17–21

Out of order. See Chapter 14. Order of Variables in Port Makefiles.

29–45

Use 5.13.3.9. <opt>_VARS and <opt>_VARS_OFF.

science/torch7-main/Makefile

PORTNAME=torch7
PKGNAMESUFFIX=-main

And then remove GH_PROJECT.

Default, remove.

science/torch7-repl/Makefile

22

Remove

Address comments. Support all options in dlib port. Incorporate some upstream fixes.

BLASLAPACK support in both dlib-cpp and py-dlib is currently problematic, because it pulls in
GCC. In dlib-cpp case this leads to crashes in testsuite, while py-dlib simply doesn't compile.

Torch7 ports are also still in bad shape - torch7-repl doesn't seem to find modules installed by other torch7-* packages.
I'm going to address this on next iteration.

Apart from BLASLAPACK option, I think dlib-cpp and py-dlib can be commited.

devel/lua-Penlight/Makefile

19–20 ↗

(On Diff #34290)

I do not think hardcoding 5.1 here is a good idea.

devel/lua-Penlight/pkg-plist

(On Diff #34290)

Also not a good idea to hard code the lua version in plist, when the default version changes or set to a different value all (or at least most) of these ports will break.

Bump. Can dlib-cpp and py-dlib be committed?

Torch isn't actively developed anymore.
