Hi Mark,
Thanks for the patch.
+(define-module (gnu packages ai) + #:use-module ((guix licenses) #:prefix license:) + #:use-module (guix utils) + #:use-module (guix download) + #:use-module (guix packages) + #:use-module (guix build-system cmake) + #:use-module (guix git-download) + #:use-module (gnu packages))I think machine-learning.scm would be a good home for this package, so a new file wouldn't be needed.
+ +(define-public libfann + (package + (name "libfann") + (version "d71d54788b")
The last release is 129 commits behind and it has been some time, so I think you are right - we should package from a git commit.
Usually we package from git using this style though (i.e. reason for not using the release, use of 'file-name', and a version that includes the last release followed by '-1.<commit>').
;; There are no recent releases so we package from git.(let ((commit "da121155a977197cab9fbb15953ca1b40b11eb87"))(package(name "newick-utils")(version (string-append "1.6-1." (string-take commit 8)))(source (origin(method git-fetch)(uri (git-reference(commit commit)))(file-name (string-append name "-" version "-checkout"))(sha256(base32"1hkw21rq1mwf7xp0rmbb2gqc0i6p11108m69i7mr7xcjl268pxnb"))))
+ (source (origin + (method git-fetch) + (uri (git-reference + (url "https://github.com/libfann/fann.git") + (commit version))) + (sha256 + (base32 + "0ibwpfrjs6q2lijs8slxjgzb2llcl6rk3v2ski4r6215g5jjhg3x")))) + (build-system cmake-build-system) + (arguments + `(#:tests? #f))I see from the website:
Once you have installed the library you can test it out by going to the examples directory and typemake runtest
, which will compile the examples and run a few of them to test that everything is working.Is that possible? Ideally, since there are tests it would be good to run them.+ (home-page "http://leenissen.dk/fann/wp/") + (synopsis "Fast Artificial Neural Network") + (description + "FANN is a free open source neural network library, which implements +multilayer artificial neural networks in C with support for both fully +connected and sparsely connected networks.") + (license license:lgpl2.1)))Otherwise LGTM. Can you send an updated patch please?
Thanks, ben
