libnih is a light-weight "standard library" of C functions to ease the development of other libraries and applications. Its goals are: * despite its name, to _not_ reimplement anything found in the standard C library or any library normally found in /lib; * use standard C types and conventions where appropriate; * have a simple and consistent programming interface; * be useful to library developers without needing to be exposed in the library's API; * not hide implementation details or structure contents, we're all adults after all. Dependencies ------------ The D-Bus messaging system is required to build the libnih-dbus library and nih-dbus-tool utility. In order to query the availability of the external library, the pkg-config tool is used; and in order to parse D-Bus introspection data, the expat XML parsing library will be used. The recommended versions are: * pkg-config 0.22 * D-Bus 1.2.16 * expat 2.0.0 These should all be available from the current release of any modern Linux distribution. For detailed compilation and installation instructions see the INSTALL file. If you've checked libnih out from revision control, or want to hack on libnih, see the HACKING file. Cross-compiling --------------- libnih uses the nih-dbus-tool utility it builds during its own build process to generate further sources to be built. When cross-compiling this will fail because the built nih-dbus-tool will most likely not be able to run on the build architecture. This can be solved by building and installing nih-dbus-tool for the build architecture first, then when performing the cross-compile, the installed copy will be used instead. If installed into a common system directory, this is automatic; if not, you can pass the path of the nih-dbus-tool binary to the configure script, e.g.: ./configure --build=i486-linux-gnu --host=gnueabi-linux-arm \ NIH_DBUS_TOOL=/cross/bin/nih-dbus-tool
I'm not sure if it's deliberate or not, but can license be changed to LGPL-2.1+ or GPL-2.0+? Instead of current GPL-2.0-only ?
I just can't find examples nor a manual... could you... ?
Hi Scott,
We're using NIH for https://github.com/cgmanager/cgmanager. However, we need to use SCM_CRED/SCM_CREDENTIALS which is not supported by dbus on Linux.
We were therefore wondering about the possibility of adding a new D-Bus annotation to nih-dbus-tool say "client must send SCM creds with this method". FWICS, annotations only affect the tools that generate bindings code but are also some sort of loose contract between the D-Bus client and the server.
The D-Bus spec only seems to touch on the precise meaning of annotations very lightly unless I'm missing something. The D-Bus tutorial does cover them in a little more detail, but it seems unreasonable to consider the tutorial part of the official spec to me.
What the spec does refer to is "well-known" annotations which implies that other annotations may be possible? Indeed, I notice that although NIH supports async methods it does so using "com.netsplit.Nih.Method.Async" rather than the semi-well-known "org.freedesktop.DBus.GLib.Async" (semi since it's not in the spec, but is in the tutorial!)
Can you offer any advice or insight into this?
Cheers,
James.

that seems to explode upon seeing DBUS_TYPE_VARIANT, looking at the code, indeed there is no support to generate that. Not a blocker for me, for now.
