Installing libusb

Installing libusb from the conda-forge channel can be achieved by adding conda-forge to your channels with:

conda config --add channels conda-forge
conda config --set channel_priority strict

Once the conda-forge channel has been enabled, libusb, libusb-cos6 can be installed with conda:

conda install libusb libusb-cos6

or with mamba:

mamba install libusb libusb-cos6

It is possible to list all of the versions of libusb available on your platform with conda:

conda search libusb --channel conda-forge

or with mamba:

mamba search libusb --channel conda-forge

Alternatively, mamba repoquery may provide more information:

# Search all versions available on your platform:
mamba repoquery search libusb --channel conda-forge

# List packages depending on `libusb`:
mamba repoquery whoneeds libusb --channel conda-forge

# List dependencies of `libusb`:
mamba repoquery depends libusb --channel conda-forge

About conda-forge

conda-forge is a community-led conda channel of installable packages. In order to provide high-quality builds, the process has been automated into the conda-forge GitHub organization. The conda-forge organization contains one repository for each of the installable packages. Such a repository is known as a feedstock.

A feedstock is made up of a conda recipe (the instructions on what and how to build the package) and the necessary configurations for automatic building using freely available continuous integration services. Thanks to the awesome service provided by Azure, GitHub, CircleCI, AppVeyor, Drone, and TravisCI it is possible to build and upload installable packages to the conda-forge anaconda.org channel for Linux, Windows and OSX respectively.

To manage the continuous integration and simplify feedstock maintenance conda-smithy has been developed. Using the conda-forge.yml within this repository, it is possible to re-render all of this feedstock's supporting files (e.g. the CI configuration files) with conda smithy rerender.

For more information please check the conda-forge documentation.

Terminology

feedstock - the conda recipe (raw material), supporting scripts and CI configuration.

conda-smithy - the tool which helps orchestrate the feedstock. Its primary use is in the construction of the CI .yml files and simplify the management of many feedstocks.

conda-forge - the place where the feedstock and smithy live and work to produce the finished article (built conda distributions)

Updating libusb-feedstock

If you would like to improve the libusb recipe or build a new package version, please fork this repository and submit a PR. Upon submission, your changes will be run on the appropriate platforms to give the reviewer an opportunity to confirm that the changes result in a successful build. Once merged, the recipe will be re-built and uploaded automatically to the conda-forge channel, whereupon the built conda packages will be available for everybody to install and use from the conda-forge channel. Note that all branches in the conda-forge/libusb-feedstock are immediately built and any created packages are uploaded, so PRs should be based on branches in forks and branches in the main repository should only be used to build distinct package versions.

In order to produce a uniquely identifiable distribution:

• If the version of a package is not being increased, please add or increase the build/number.
• If the version of a package is being increased, please remember to return the build/number back to 0.

libusb-feedstock's Issues

@conda-forge-admin, please rerender

Additional comment:

Checking whether the recent addition of cdt_name to a zip key with c_stdlib_version in conda-forge-pinning breaks rerendering (which I expect).

Broken patch for libudev?

Hi,
I must admit I'm not good enough to entirely parse what's going on at:
https://github.com/conda-forge/libusb-feedstock/blob/master/recipe/post-link.sh

...but I feel like some problems I am running into with a Ros package using your libusb from conda might stem from something happening there. When checking library dependencies I get a:
libudev.so.0 => not found

What is the intention of the patch? I can provide more context if needed!

Many thanks!

Has anybody tested if this works with Ubuntu 18.04?

My Ubuntu 18.04 builds seem to fail with

ImportError: libudev.so.0: cannot open shared object file: No such file or directory

I think it is because ubuntu uses libudev1 and we have compiled with libudev0

pkgconfig files for Windows

Currently the Windows build does not include a pc file, which makes it hard to find on Windows.

It is needed for a Windows build of ftdi (see conda-forge/staged-recipes#14626).

Fix broken dependency to libudev

• I read the conda-forge documentation and could not find the solution for my problem there.

Issue:

Details about system ( conda info ):

$ conda info libusb

libusb 1.0.24 h18f079d_4 conda-forge

How libusb-1.0.pc looks like

Name: libusb-1.0
Description: C API for USB device access from Linux, Mac OS X, Windows, OpenBSD/NetBSD and Solaris userspace
Version: 1.0.24
Libs: -L${libdir} -lusb-1.0
Libs.private: -ludev -lrt -lpthread 
Cflags: -I${includedir}/libusb-1.0

How it should instead look like:

Name: libusb-1.0
Description: C API for USB device access from Linux, Mac OS X, Windows, OpenBSD/NetBSD and Solaris userspace
Version: 1.0.24
Libs: -L${libdir} -lusb-1.0 -ludev
