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

Greeter -platform freerdp

Test with QT Browser QupZilla (Ubuntu)

2 simultaneous connections to the same QupZilla

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

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

QT-Plugin

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

Code:

## GIT

sudo zypper install git

## QT5 qtchooser

sudo zypper install qtchooser qt5-qmake libxkbcommon-devel glib2-devel qt5-qtgui qt5-qtcore

## CMAKE make

sudo zypper install cmake make

## QT5-qtplatformsupport-devel

sudo zypper install qt5-qtplatformsupport-devel


## download sources

cd ~
mkdir git
cd git

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


sb2 -t SailfishOS-armv7hl -R sudo zypper install libxkbcommon-devel glib2-devel
sb2 -t SailfishOS-armv7hl -R zypper install cmake
sb2 -t SailfishOS-armv7hl -R zypper install openssl-devel

## compile FreeRDP

cd FreeRDP

sb2 -t SailfishOS-armv7hl -R 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
sb2 -t SailfishOS-armv7hl -R make
sb2 -t SailfishOS-armv7hl -R make install

sb2 -t SailfishOS-armv7hl -R make clean
sb2 -t SailfishOS-armv7hl -R rm CMakeCache.txt
sb2 -t SailfishOS-armv7hl -R cmake -DCMAKE_INSTALL_PREFIX="~/freerdp" -DCMAKE_BUILD_TYPE=Release -DSTATIC_CHANNELS=on -DWITH_SERVER=ON -DWITH_X11=OFF -DARM_FP_ABI=hard
sb2 -t SailfishOS-armv7hl -R make
sb2 -t SailfishOS-armv7hl -R make install


## QT Plugin

cd ~/git/qfreerdp_platform

sudo zypper install pcre-devel glib2-devel libxkbcommon libxkbcommon-devel

sb2 -t SailfishOS-armv7hl -R zypper install libxkbcommon-devel libxkbcommon glib2-devel pcre-devel

sb2 -t SailfishOS-armv7hl -R zypper install qt5-qttools-qtuitools-devel



export INSTALL_PATH=$HOME/freerdp
export PKG_CONFIG_PATH=$INSTALL_PATH/lib/pkgconfig/:$INSTALL_PATH/share/pkgconfig/

sb2 -t SailfishOS-armv7hl -R qtchooser --qt=5 -run-tool=qmake
sb2 -t SailfishOS-armv7hl -R make

export QT_PLUGIN_PATH=$(pwd)/plugins

#or later copy to qt plugins path: /usr/lib/qt5/plugins/platforms/

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/

#add ld-config
vi /srv/mer/targets/SailfishOS-armv7hl/etc/ld.so.conf.d/freerdp.conf

/srv/mer/targets/SailfishOS-armv7hl/lib/freerdp/

sb2 -t SailfishOS-armv7hl -R ldconfig

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'.

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.
