Hi Genode Comunity
I need porting a Qt4.8 application on GenodeOS. I'm using the old
qt4 support on GenodeOS, and it's working fine with the examples.
Now, my applications have another dependencies like WebToolkit (Wt)
library. I'm working on the support of this library. I have followed
the Porting Guide and have made some progress.
Basically I have made a basic support of some Boost libraries needed
to compile Wt: system, signals, random, date_time, regex and thread.
These libraries compile fine on GenodeOS.
I have tried to bring up the Wt library. To do this, i have reviewed
the build log of the library. Using this build log I have prepares
the build files for the library and make a dummy example (for test
the compilation of the library) using one of the examples on
repos/libports/src/test/libports/
Checking the dependencies of the compiled library on my pc I've got
readelf -a libwt.so | grep NEEDED
 0x0000000000000001 (NEEDED)            Shared library:
[libboost_thread.so.1.55.0]

[libc.so.6]
 0x0000000000000001 (NEEDED)            Shared library:
[ld-linux-x86-64.so.2]
Based on it, i have set the dependencies to compile the Wt library
on GenodeOS:
LIBS += libc libc-stdlib libm cxx stdcxx pthread
boost_system boost_date_time boost_random boost_signals
boost_filesystem boost_thread boost_regex
At this point the source code of the library compiles fine, but when
to try to link the dummy application with the compiled library get
this error:
Program test/libports/wt/test-webtoolkit
   LINK    test-webtoolkit

Some body have any suggestion or any idea about this? I'm missign
some library dependencie?
Best regards
