Alright... I think I just did it on our SLES12 SP3 platform =)
Configure and compile freerdp1
cd /root/FreeRDP-1.0.2
cmake -DCMAKE_BUILD_TYPE=Debug -DWITH_SSE2=ON -DWITH_CUPS=OFF
-DWITH_FFMPEG=OFF -DWITH_ALSA=OFF -DWITH_X11=OFF -DWITH_XKBFILE=OFF .
make
Assemble the compiled shared objects
cd /root/
mkdir /tmp/fr1
find /root/FreeRDP-1.0.2/ -iname 'libfree*so' | xargs cp -t /tmp/fr1
Try to configure and compile guacamole while pointing it to FreeRDP-1
cd /root/guacamole-server-0.9.13-incubating
make clean
LDFLAGS="-L/tmp/fr1" CPPFLAGS="-I/root/FreeRDP-1.0.2/include/"
./configure --prefix=/opt/guac-0.9.13a --with-init-dir=/etc/init.d
make
make install
