Instead of hardcoding library files locations into your build files, you put pkg-config invocations there. That is why a program called pkg-config exists. Some libraries have their files installed in a known place, but Linux distributions can choose their custom locations.

That is why you need sysroot - more on sysroot below. library header files, which should match those in the target host rather than those in your build host. While it is doing its job it needs to consult several files, e.g. a kernel, you cannot get away with just a bare compiler. It is a compiler which itself is a program built for running on your build host and generating binaries for the target host. You need a cross-compiler in the first place. No matter if we need to use autotools style (libusbgx), cmake style (gt, cmtp-responder) or, say, meson style, the general concepts are the same. This process is known as cross-compiling.

What we want to achieve is to build a piece of software so that it runs on a different kind of machine than the one used for building. If, however, you expect you will be rebuilding cmtp-responder often, cross-compiling it is definitely worth the initial effort and the rest of this post is dedicated to this latter approach.

In either case the process should look like building for an x86 on an x86, and you need the same kind of packages installed on the board (or in your rootfs).

For building natively you have yet another option, you can compile on your PC in an emulated environment (which does not need to be full system emulation, just a target rootfs and a static qemu inside it is enough to chroot into and build as if you were building natively). It will definitely take more time than cross-compilation, but is a viable option. Options to build nativelyįirst of all, you can build natively on the target board. So let's go step by step through building the platform-dependent pieces. Systemd units and the gadget scheme are obviously platform-independent. The software pieces which you need to build specifically for your target board are: The hardware I am using is a RockPi 4 model B, but you can easily adjust the instructions to your particular board and I will mark all the places which are hardware-specific. It is definitely beyond the scope of this post to talk about all possible pieces of hardware.

IS MTP HOST SPYWARE HOW TO

What I will talk about today is how to build the needed components for running on real hardware.Īs far as the hardware is concerned, you can run your gadgets on any Arm board which provides a UDC (OTG) chip which is wired to an actual USB connector on the board (so RPi Zero will work with this, but RPi will not). The first paragraph contains enough links for you to follow, and I encourage you to do it if you haven't done so yet. In this post I won't go into details of how to compose a gadget or how to integrate that process with systemd. You can also watch me talking about USB gadgets at ELC 2019 and Linux Piter 2019. It is in this latter post that I promised you running cmtp-responder on real hardware. Then I presented cmtp-responder, a permisively-licensed MTP responder implementation and showed how to play with it on your PC with dummy_hcd driver. In part2 I wrote about one particular USB gadget function - FunctionFS - and its integration with systemd.

To recap: In part1 of this series I introduced you to the concept of USB gadgets, their configfs composition interface, available opensource tools and basic systemd integration. Did you know you could run a permissively-licensed MTP (Media Transfer Protocol) implementation with minimal dependencies on an embedded device? Here's a step-by-step guide on how to easily run cmtp-responder on a Rock Pi 4 or any other board equipped with a UDC.
