Hello
There is an implementation of some of these functions callable by C code in base/src/base/cxx/misc.cc which becomes part of cxx.lib.a, but I don't see a C header file which exports the interfaces. Depending on the target setup the compiler either takes the header file(s) from itself (system) or from Genode's libc, but the implementation is taken from the cxx library (since it appears in the LIBS list of all targets). I'd prefer to have header files which are created from the sources they are referring to instead of taking them from elsewhere (although I admit that prototypes of memcpy() or printf() should be the same on most systems).

Hi Peter,
As an addition to the previous post by me, I have some pre-existing
C code
that
I want to use in a Genode server I have created, and I don't really
want to
change this code. Currently, i'm not able to utilize functions like
printf,
memcpy etc in the C code i've written. What header files can I
include to
ensure
that functions like memcpy and printf work in my code? From what I
can see,
the
build process does not recognize the standard header files at all.
the functionality you are referring to is provided by the C library.
Just include the 'libc' repository to the 'REPOSITORIES' declaration
of your '<builddir>/etc/build.conf'. This way, Genode's build system
will incorporate the C library into the build process. For using the
C library for your program, you need to add 'libc' to the 'LIBS' of
your 'target.mk' file. For more information, please refer to
'libc/README'.
