Troubles linking Wt library

[Reinier Millo Sánchez]

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:

      0x0000000000000001 (NEEDED)             Shared library:

      0x0000000000000001 (NEEDED)             Shared library:

      0x0000000000000001 (NEEDED)             Shared library:

      0x0000000000000001 (NEEDED)             Shared library:
    [libpthread.so.0]
      0x0000000000000001 (NEEDED)             Shared library:
    [libstdc++.so.6]
      0x0000000000000001 (NEEDED)             Shared library: [libm.so.6]
      0x0000000000000001 (NEEDED)             Shared library:
    [libgcc_s.so.1]
      0x0000000000000001 (NEEDED)             Shared library: [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
    /home/millo/XEOS/GenodeOS/build/foc_rpi/var/libcache/wt/wt.lib.so:
    undefined reference to `kevent'
    /home/millo/XEOS/GenodeOS/build/foc_rpi/var/libcache/wt/wt.lib.so:

    undefined reference to `sendmsg'
    collect2: error: ld returned 1 exit status

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

Best regards
