SailfishOS RDP Server Plugin for QT Apps

Soooo my first day with the SailfishOS SDK + Emulator ... tried something funny what mabye can be integrated + advanced in future.

Access your QT-App remotly with RDP

Simply add this plugin to your QT-Plugin-Folder and without any change to the sourcecode of your application run it like this:

Code:

./myqtapp -platform freerdp

I was told that for now or longer there will be no QTQuick2-Apps / OpenGL support possible, as "Qt guys have dropped the raster
backend for QtQuick"

But you CAN code SailfishOS QT-Apps WITHOUT QTQuick.
I successfully commented out the lines and had to restructure some elements as they now are not available any longer.

But slidemenu etc still working.

#in files .cpp
//#include <QtQuick>

#in files .qml
//import QtQuick 2.0

Greeter -platform wayland-egl

About

This is a QT platform plugin that allows QT-Applications to run headless and listening on RDP-Port for incoming RDP-Connections.

All one has to do would be to deploy the rquired libraries and the single QT-Platform-Plugin "libqfreerdp.so" to the Plugins dir.

Then one can call QT-Application like this without any change to the sourcecode of your application:

Code:

./myqtapp -platform freerdp

Requirements to build

QT5, qtchooser
FreeRDP (stable / nightly)
qfreerdp_platform

(build tools: cmake, gcc, make, ...)

Would be great to get RDP-QT-Remote-App-Support in future!

I was in contact with the author of the plugin and he was so kind to fix some problems that made it harder to get it compiled, fixed the distorted output (resizing) and added improvements already (thank you very much for that!).

VirtualBox Portable + SailfishOS SDK Setup

I am running a portable version of VirtualBox v4.3.6 and in the past the SailfishOS SDK was searching for a regpath to VirtualBox, so I added the following on my Windows x64

Code:

Windows Registry Editor Version 5.00



[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Oracle\VirtualBox]

"InstallDir"="P:\\VirtualBox\\app64"

VirtualBox + SailfishOS SDK + Proxy

I had some trouble because I am behind a proxy.

For me it helped to install packages with zypper, but isn't installed by default.

File: /etc/sysconfig/proxy

Code:

PROXY_ENABLED="yes"

HTTP_PROXY="http://proxy.server.com:8080"

HTTPS_PROXY="http://proxy.server.com:8080"

FTP_PROXY="http://proxy.server.com:8080"

GOPHER_PROXY=""

NO_PROXY="localhost, 127.0.0.1/8, 192.168.0.0/16, 172.16.0.0/12, 10.0.0.0/8

File: /etc/profile:

Code:

sudo vim /etc/profile



#append these lines

export http_proxy="http://proxyuser:proxypwd@proxy.server.com:8080"

export https_proxy="http://proxyuser:proxypwd@proxy.server.com:8080"

export ftp_proxy="http://proxyuser:proxypwd@proxy.server.com:8080"



reboot

Reboot

Then manually download the RPMs for zypper and augeas-libs (example Repo) by using

Code:



curl -O http://releases.sailfishos.org/sdk/0.20130731/jolla/i486/core/i486/zypper-1.8.3-1.1.3.i486.rpm



curl -O http://releases.sailfishos.org/sdk/0.20130731/jolla/i486/core/i486/augeas-libs-1.0.0-1.1.1.i486.rpm



pkcon install-local zypper-1.8.3-1.1.3.i486.rpm augeas-1.0.0-1.1.1.i486.rpm



zypper refresh



zypper install git



git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080

VirtualBox + MerSDK + Shared Folder + Symlink = Protocol Error

I had a problem compiling FreeRDP on my Windows 8.1 because I got an Error about symlinks. Then tried to create one on my own, it failed.

My short workaround:
I copied the directories ".ssh" + ".scratchbox2" then made the shared folder unavailable so that I had the Linux home folder of the MerSDK-VM, copied back the folders.

There is mentioned some ways to fix this, but all of it didn't work for me.

Link1
Link2

Code:



  # On Windows 7/8 execute the following from an elevated (Admin!, UAC!) command prompt to make it work:

  # fsutil behavior set SymlinkEvaluation L2L:1 R2R:1 L2R:1 R2L:1

  # If you normally work with an non-admin, you additionally have to do this:

  # Run “secpol.msc” as Admin and navigate to “Local Policies-User Rights Assignments” (

  # "Locale Richtlinien-Zuweisen von Benutzerrechten") and add your user to “Create symbolic links” 

  # ("Erstellen symbolischer Verknüpfungen"). Will work at next log on of the user 

  # RUN THE CONSOLE AND VIRTUALBOX AS ADMIN TO EXECUTE VAGRANT!!!!!!

  #

  # Allow VirtualBox to create symlinks in the shared folder.





  

  #VBoxManage setextradata YOURVMNAME VBoxInternal2/SharedFoldersEnableSymlinksCreate/YOURSHAREFOLDERNAME 1

   VBoxManage setextradata MerSDK VBoxInternal2/SharedFoldersEnableSymlinksCreate/home 1

   VBoxManage setextradata MerSDK VBoxInternal2/SharedFoldersEnableSymlinksCreate/target 1



  #Verify by running:



  #VBoxManage getextradata YOURVMNAME enumerate

  VBoxManage getextradata MerSDK enumerate

 

 

Run VirtualBox AND QTCreator as ADMIN! If staring the merSDK-VM from QTCreator, you will see it in the VirtualBox-Folder if both are running as admin.

SailfishOS SDK + Putty + Public Private KeyAuth

Download and run PuttyGen

Generate Keypair: SSH-2 RSA 2048 bit

Save the private key to file
Save public key to file

APPEND (Copy&paste) the public key (displayed in the upper textarea in PuttyGen)
to the authorized_key files of SailfishOS SDK:

SailfishOS\mersdk\ssh\root\authorized_keys
SailfishOS\mersdk\ssh\mersdk\authorized_keys
SailfishOS\emulator\1\ssh\nemo\authorized_keys
SailfishOS\emulator\1\ssh\root\authorized_keys

Re: SailfishOS RDP Server Plugin for QT Apps

Developer Infos

I will try to write some information so if someone wants to try to build for arm.

Code:

pkcon install zypper

zypper install cmake gcc gcc-c++



pkcon install qtchooser

Download Sources

Code:

mkdir ~/git

cd ~/git



git clone https://github.com/awakecoding/FreeRDP/



git clone https://github.com/hardening/qfreerdp_platform

Prepare and build

For now I needed to build FreeRDP-Libs two times, once monolithic and once without, as the other sources currently search from both.

"-DARM_FP_ABI=hard" is only needed on arm.

FreeRDP

Code:

#first build monolithic



cd ~/git/FreeRDP

cmake -DCMAKE_INSTALL_PREFIX="~/freerdp" -DCMAKE_BUILD_TYPE=Release -DSTATIC_CHANNELS=on -DWITH_SERVER=ON -DWITH_X11=OFF -DMONOLITHIC_BUILD=ON -DARM_FP_ABI=hard



make

make install





#second build

make clean

rm CMakeCache.txt



cmake -DCMAKE_INSTALL_PREFIX="~/freerdp" -DCMAKE_BUILD_TYPE=Release -DSTATIC_CHANNELS=on -DWITH_SERVER=ON -DWITH_X11=OFF -DARM_FP_ABI=hard



make

Re: SailfishOS RDP Server Plugin for QT Apps

QT-Plugin

Update 2014-01-15

I succesfully compiled FreeRDP + qfreerdp on the SailfishOS SDK VM for armv7hl

Next step:
Now is the question how to get the missing QT-Libs onto the phone together with the app.

... work in progress ... would be happy about any help!

Compile on MerSDK-VM

I documented nearly every step what I did, so there may be more than nessesary, if: tell me.

I connected directly to the MerSDK-VM with putty after generating my own keys like descriped earlier.

mersdk@127.0.0.1
Port: 2222
use private key file

Running on the Jolla Phone

Now how to get it running on the phone, what is missing ...

Static build possible?

Maybe it would be possible to build the plugin as static, but that may require to recompile QT.

Code:

#### EXPERIMENTAL #####



## try to build static #######

vi /srv/mer/targets/SailfishOS-armv7hl/usr/share/qt5/mkspecs/common/gcc-base-unix.conf



#QMAKE_LFLAGS_SHLIB     += -shared

QMAKE_LFLAGS_SHLIB     += -static



#copy arm-compiled-freerdp-libs



cp -R /home/mersdk/freerdp/lib/* /srv/mer/targets/SailfishOS-armv7hl/lib/freerdp/

Re: SailfishOS RDP Server Plugin for QT Apps

A static build of Qt won't work, at least not out of the box. You could static link your dependencies into the plugin you're building (but keep in mind that you have three license choices for Qt when thinking about redistribution of your plugin).

If your plugin has dependencies, you can statically link those into the plugin if that's an option. Alternatively, you need to deploy all libraries it depends on as well as the plugin itself.

To view dependencies at link time, take a look around google for 'ldd'.

Re: SailfishOS RDP Server Plugin for QT Apps

thank you very much for your quick answer. yes I read about the license problem, and as qt is completely new for me it is vefy difficult to find workarounds.

so if I underdtand, I would have to extract everything that conflicts and put in in place manually and hope to get it working.
