package-managers

I have a software application that can be built and installed with stack . I would like to offer a binary package as well for Linux and Mac. For this purpose I'm considering nix , since, among other things, it can be used in Linux and Mac. This will save me the trouble of having to maintain two package types. After reading about how nix packages are defined, I would expect that a stack based project could be built with a configuration that would look like: { stdenv, fetchurl, stack }: # we need to depend on stack stdenv.mkDerivation { name = "some-haskell-package-0.1"; builder = ./builder.sh;

I'm using buildroot to create a rootfs running on my ARM platform. I'd like to have a package manager on my platform to easily install packages, like apt-get in ubuntu. I found opkg, who can be simply added to the buildroot build, but I can't find any information about how to find a repository. Also, reading some stuff on the web about this, I also read that buildroot didn't include a package manager. Isn't opkg a package manager? Or just some kind of frontend to fetch packages? I don't really understand what a package manager consist of, and I don't find any information about this. Could

I'm trying to load a library I have hosted on BitBucket using composer as explained both in the official documentation and here , but keep receiving the following error: [Composer\Repository\InvalidRepositoryException] No valid composer.json was found in any branch or tag of [repository URL], could not load a package from it. Here is my project composer.json: { "name": "Project name", "require": { "my-vendor/my-package": "dev-master" }, "repositories": [ { "type": "vcs", "url": [repository URL] } ] } And here is the composer.json in my remote repository (that apparently can't be found): {

I need to download a python package with all its dependencies without installing, sneaker-net it to a computer without connection to the internet, and install it there. For example, I want to install buildbot, lettuce, etc. The computer is a Windows 7 machine, using Python 2.7. If the package has native extensions, I can build them on the computer. You can use pip , with the --download option, which will download the main package and its dependancies, without installing them. pip install --download="/path/to/downloaded/files" sneaker-net And use these files one the local machine with: pip

I am developing an android application and I need android device features. I know that, by using package manager, getSystemAvailableFeatures method should be available. Still the method is not available Can any one help me by post some example or source code related to that. GrAnd I use the following function to determine if a feature is available: public final static boolean isFeatureAvailable(Context context, String feature) { final PackageManager packageManager = context.getPackageManager(); final FeatureInfo[] featuresList = packageManager.getSystemAvailableFeatures(); for (FeatureInfo f :

I wonder about installing the latest version of Ruby on Ubuntu 9.04. Now I can run through the ./configure and make stuff fine, but what I wonder about: how to avoid conflicts with the packaging system? For example if some other package I install depends on Ruby, wouldn't the package manager install the (outdated) Ruby package and in the worst case overwrite my files? So I think I need some way to tell Ubuntu that Ruby is in fact already installed? Sam Saffron Save yourself the headache and use RVM ( Ruby Version Manager ) Keep in mind, Rails 3 works best with Ruby 1.9.2. Ruby 1.9.2 fixes up
