For various reasons, you may need to build HIDAPI on your own.
It can be done in several different ways:
Meson
(requires CMake);Autotools build system is historically the first mature build system for HIDAPI. The most common usage of it is in its separate README: BUILD.autotools.md.
NOTE: for all intentions and purposes the Autotools build scripts for HIDAPI are deprecated and going to be obsolete in the future. HIDAPI Team recommends using CMake build for HIDAPI.
CMake build system is de facto an industry standard for many open-source and proprietary projects and solutions. HIDAPI is one of the projects which use the power of CMake to its advantage. More documentation is available in its separate README: BUILD.cmake.md.
Meson build system for HIDAPI is designed as a wrapper over CMake build script. It is present for the convenience of Meson users who need to use HIDAPI and need to be sure HIDAPI is built in accordance with officially supported build scripts.
In the Meson script of your project you need a hidapi = subproject('hidapi')
subproject, and hidapi.get_variable('hidapi_dep')
as your dependency. There are also backend/platform-specific dependencies available: hidapi_winapi
, hidapi_darwin
, hidapi_hidraw
, hidapi_libusb
.
If you don't know where to start to build HIDAPI, we recommend starting with CMake build.
Regardless of what build system you choose to use, there are specific dependencies for each platform/backend.
Depending on which backend you‘re going to build, you’ll need to install additional development packages. For linux/hidraw
backend, you need a development package for libudev
. For libusb
backend, naturally, you need libusb
development package.
On Debian/Ubuntu systems these can be installed by running:
# required only by hidraw backend sudo apt install libudev-dev # required only by libusb backend sudo apt install libusb-1.0-0-dev
On FreeBSD, you will need to install libiconv. This is done by running the following:
pkg_add -r libiconv
Make sure you have XCode installed and its Command Line Tools.
You just need a compiler. You may use Visual Studio or Cygwin/MinGW, depending on which environment is best for your needs.
Instead of using one of the provided standalone build systems, you may want to integrate HIDAPI directly into your source tree.
If your project uses CMake as a build system, it is safe to add HIDAPI as a subdirectory.
If the only option that works for you is adding HIDAPI sources directly to your project's build system, then you need:
hidapi
folder to the include path when building hid.c
;hid.c
;NOTE: the above doesn't guarantee that having a copy of <backend>/hid.c
and hidapi/hidapi.h
is enough to build HIDAPI. The only guarantee that <backend>/hid.c
includes all necessary sources to compile it as a single file.
Check the manual makefiles for a simple example/reference of what are the dependencies of each specific backend.
Manual Makefiles are provided mostly to give the user an idea what it takes to build a program which embeds HIDAPI directly inside of it. These should really be used as examples only. If you want to build a system-wide shared library, use one of the build systems mentioned above.
To build HIDAPI using the manual Makefiles, change the directory of your platform and run make. For example, on Linux run:
cd linux/ make -f Makefile-manual
To build the HIDAPI DLL on Windows using Visual Studio, build the .sln
file in the windows/
directory.
To build HIDAPI using MinGW or Cygwin using Autotools, use general Autotools instruction.
Any windows builds (MSVC or MinGW/Cygwin) are also supported by CMake.
