------------------------------------------------------------------
Looks like the Stream_New and Stream_Free symbols are exported in FreeRDP 1.1
from the libwinpr-utils file:
root@host:~/guacamole-server-0.9.12-incubating# nm -D
/usr/lib/x86_64-linux-gnu/libwinpr-utils.so.0.1.0 |grep Stream_New
0000000000006fb0 T Stream_New
root@host:~/guacamole-server-0.9.12-incubating# nm -D
/usr/lib/x86_64-linux-gnu/libwinpr-utils.so.0.1.0 |grep Stream_Free
0000000000007010 T Stream_Free
So maybe the guacai-client.so file needs to link against that file? A quick
change to the src/protocols/rdp/Makefile seems to resolve this issue. Around
line 715 should be guacai_ldflags=, and adding -lwinpr-utils to the end of the
last line (after -lfreerdp-codec) causes that library to be linked against the
libwinpr-utils shared library, which removes the error.
{code}
guacai_ldflags = \
-module -avoid-version -shared \
-lpthread \
-lfreerdp-core -lfreerdp-cache -lfreerdp-client -lfreerdp-utils

> I know this problem was discussed in resolved thread, but it is a bit

> because it keeps disconnecting immediately, the only why is using a RDP
