<font face="Courier 10 Pitch">In theory, as Norman mentioned, you
should be OK with STL on Genode. In this context you shouldn't use
the Genode allocator/new operator. I have not tested them
extensively either so I would be interested to hear how you get
on.<br>

Thanks for your answer!<br>
<br>
My interest about STL containers has quite simple prerequisite.
As far as I know Genode implementations of data structure
(particularly, Avl_tree) has some issues and Genodelabs does not
recommend it for usage in user applications. The reasons that
issues are still not resolved is quite serious: Genode is kept
as simple as possible. So, I was thinking about making a kind of
porting of STL to Genode. But, it seems that this work is
redundant since it is possible to use containers by means of
specifying stdcxx in makefile. The only trouble is using Genode
allocators/new operator instead of native C++ ones.<br>
<br>
I have this only in mind and even did not start to do anything.

<br>
W.R.T. Genode allocators and STL - I would of thought that you
would not need to do this directly, but that the Genode stdc++
port backs onto a port of malloc, that in turn backs onto
Genode allocator calls.<br>
<br>
Is there something specific you are trying to do?<br>

Is it possible to use STL containers using mentioned way? (change target.mk)

<pre wrap="">yes. In order to use the C++ standard library, you will need to prepare
it first. To do that, just issue the following command from within the
'libports' repository:
make prepare PKG=stdcxx
This will download and integrate the library with Genode. Also make sure
that the 'libports' repository is specified in your build directory's
'REPOSITORIES' declaration (in '<build-dir>/etc/build.conf').
Please note, however, that we at Genode Labs don't use the C++ standard
library much. So the stdcxx library does not receive much testing from
our side. If you encounter problems with it, please bear with us. Also,
some modern bits such as C++11 concurrency features are not supported.
The containers should work without problems though.
