Hello Wouter,
* Wouter van Oijen wouter.van.oijen@technolution.nl:
I succeeded in building and starting Mosquitto under Genode, but it fails due to the not-implemented functions geteuid() and getpwnam(). See log below. Are these functions already implemented somewhere? How should I continue from here?
At least 'getpwnam' got implemented by [1] but you need to configure the libc (please look at the run script included in the commit). Most of the time the user account/identity functions that are used to check various properties in a multi-user system (e.g. to drop priviledges or check for running as root) are of no concern on Genode - after all there is just a single user and the seperation is done at another layer, not the libc. You might have to check what your program expects and how, if necessary, to adapt it.

The back end implementation of the libc is located in [2].

Also, what does the warning about exec_static_constructors() mean?
[…]
Ported software might depend on calling static constructors but we have to make sure to execute the functions at the proper time, i.e., after the component's environment has been completely initialized. For now we do that for every libc based component unconditionally. The dynamic run-time linker, however, will print this diagnostic message in case the binary does not have any static constructors that need to be executed.
