Installation fails on arch linux

[UnconventionalMindset]

The installation fails on archlinux with the following error:

Package 'libusb', required by 'virtual:world', not found

My understanding is that the build fails due to the package libusb having a different name or installation path in Arch Linux.

This custom made scripts (AUR package) for Arch linux, are not working either:
https://github.com/asonix/psmoveapi-arch
This scripts also includes some patches that are outdated that I could update.

I am happy to contribute to this repo and try to test and to create a fix for those issues, but I may need a little help.

Any suggestions on where I can to fix those issues?

Weird, it seems like libusb does exist in Arch Linux:

https://www.archlinux.org/packages/core/x86_64/libusb/

(I don't have any experience with Arch Linux)

I have absolutely no experience with Arch Linux either. What exactly did you execute to install? Posting the build log containing the error message would be helpful.

[UnconventionalMindset]

Arch Linux is not that particular, basically to install C++ applications works similar to other distro with maybe few extra things.
The AUR package is just a script that tells the system how to install the software. So rather than building from sources yourself you just download a script from a package repository and it will install the software for you following steps that are known to be working.

The steps I run are as following:

git clone --recursive https://github.com/thp/psmoveapi.git
cd psmoveapi/
mkdir build
cd build/
cmake ..

and the build log in the terminal is:

Also, these are my libusb-related installed packages:

$ pacman -Q | grep libusb
lib32-libusb 1.0.23-1
libusb 1.0.23-2
libusbmuxd 2.0.1-1

libusb is not split into normal and -dev like in Ubuntu, the standard package should contain both:

This is just a guess, could you please try adding a new line here?

https://github.com/thp/psmoveapi/blob/master/cmake/FindUSB1.cmake#L32
usr/include or usr/include/libusb-1.0

Based on:
https://www.archlinux.org/packages/core/x86_64/libusb/

So this is CMake failing to locate libusb. See the pkg_check_modules call in src/utils/CMakeLists.txt. I suspect the problem is that you have libusb-1.0 installed on your system while CMake is looking for libusb (which would be version < 1.0). Try changing that identifier to libusb-1.0 in the pkg_check_modules call to see if that fixes it.

[nitsch]

I just realized that the code that actually needs libusb only works with the old API, i.e. not libusb-1.0 but libusb. Since both APIs are incompatible, simply linking against libusb-1.0 (after having made CMake find it) won't work. So you either need to install libusb or remove that part of the build. It looks as if there already is an option for that (PSMOVE_USE_SIXPAIR), but that won't stop CMake from demanding the library be installed. I added #406 as a note to fix this.

@JacopoGobbi Did this solve your issue?

[UnconventionalMindset]

@nitsch Just tried it today on my laprop (before I was on my desktop) and by running cmake, it found libusb 0.1.12 which I do not see installed. Maybe it is thanks to libusb-compat 0.1.7-1? I am surprised it built successfully.
I am also having other issues about installing but still trying to figure out (I know a bit about C but apparently not enough, especially to handle C++).

[nitsch]

it found `libusb 0.1.12` which I do not see installed. Maybe it is thanks to `libusb-compat 0.1.7-1`?

Yes, I would think so. Arch's libusb-compat points to https://github.com/libusb/libusb-compat-0.1 which self-describes as: "A compatibility layer allowing applications written for libusb-0.1 to work with libusb-1.0. libusb-compat-0.1 attempts to look, feel, smell and walk like libusb-0.1."

@JacopoGobbi Is this issue solved?
