##Build instructions for Qt Creator 4.0.3 under Ubuntu 16.04 and Modify Fonts

###Prepare

###Prepare folder

Choose a folder for the future build, for example /home/user/TBuild There you will have two folders, Libraries for third-party libs and tdesktop (or tdesktop-master) for the app.

###Clone source code

By git – in Terminal go to /home/user/TBuild and run

git clone https://github.com/telegramdesktop/tdesktop.git

or download in ZIP and extract to /home/user/TBuild rename tdesktop-master to tdesktop to have /home/user/TBuild/tdesktop/Telegram/Telegram.pro project

###Prepare libraries

####Install dev libraries

sudo apt-get install libexif-dev liblzma-dev libz-dev libssl-dev libappindicator-dev libunity-dev zlib1g-dev install libopus-dev

####FFmpeg

In Terminal go to /home/user/TBuild/Libraries and run

git clone git://anongit.freedesktop.org/git/libva
cd libva
./autogen.sh --enable-static
make
sudo make install
cd ..

git clone https://github.com/FFmpeg/FFmpeg.git ffmpeg
cd ffmpeg
git checkout release/3.1

sudo apt-get update
sudo apt-get -y --force-yes install autoconf automake build-essential libass-dev libfreetype6-dev libgpac-dev libsdl1.2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev pkg-config texi2html zlib1g-dev
sudo apt-get install yasm

./configure --prefix=/usr/local --disable-programs --disable-doc --disable-everything --enable-protocol=file --enable-libopus --enable-decoder=aac --enable-decoder=aac_latm --enable-decoder=aasc --enable-decoder=flac --enable-decoder=gif --enable-decoder=h264 --enable-decoder=h264_vdpau --enable-decoder=mp1 --enable-decoder=mp1float --enable-decoder=mp2 --enable-decoder=mp2float --enable-decoder=mp3 --enable-decoder=mp3adu --enable-decoder=mp3adufloat --enable-decoder=mp3float --enable-decoder=mp3on4 --enable-decoder=mp3on4float --enable-decoder=mpeg4 --enable-decoder=mpeg4_vdpau --enable-decoder=msmpeg4v2 --enable-decoder=msmpeg4v3 --enable-decoder=opus --enable-decoder=vorbis --enable-decoder=wavpack --enable-decoder=wmalossless --enable-decoder=wmapro --enable-decoder=wmav1 --enable-decoder=wmav2 --enable-decoder=wmavoice --enable-encoder=libopus --enable-hwaccel=h264_vaapi --enable-hwaccel=h264_vdpau --enable-hwaccel=mpeg4_vaapi --enable-hwaccel=mpeg4_vdpau --enable-parser=aac --enable-parser=aac_latm --enable-parser=flac --enable-parser=h264 --enable-parser=mpeg4video --enable-parser=mpegaudio --enable-parser=opus --enable-parser=vorbis --enable-demuxer=aac --enable-demuxer=flac --enable-demuxer=gif --enable-demuxer=h264 --enable-demuxer=mov --enable-demuxer=mp3 --enable-demuxer=ogg --enable-demuxer=wav --enable-muxer=ogg --enable-muxer=opus

make
sudo make install

####Install dev libraries (continue)

sudo apt-get install portaudio19-dev libopenal-dev libxkbcommon-dev

####Qt 5.6.0, slightly patched

In Terminal go to /home/user/TBuild/Libraries and run

git clone git://code.qt.io/qt/qt5.git qt5_6_0
cd qt5_6_0
git checkout 5.6
perl init-repository --module-subset=qtbase,qtimageformats
git checkout v5.6.0
cd qtimageformats && git checkout v5.6.0 && cd ..
cd qtbase && git checkout v5.6.0 && cd ..

#####Apply the patch

cd qtbase && git apply ../../../tdesktop/Telegram/Patches/qtbase_5_6_0.diff && cd ..

#####Building library

Install some packages for Qt (see /home/user/TBuild/Libraries/qt5_6_0/qtbase/src/plugins/platforms/xcb/README)

sudo apt-get install libxcb1-dev libxcb-image0-dev libxcb-keysyms1-dev libxcb-icccm4-dev libxcb-render-util0-dev libxcb-util0-dev libxrender-dev libasound-dev libpulse-dev libxcb-sync0-dev libxcb-xfixes0-dev libxcb-randr0-dev libx11-xcb-dev libffi-dev

In Terminal go to /home/user/TBuild/Libraries/qt5_6_0 and there run

OPENSSL_LIBS='-L-L/usr/lib/x86_64-linux-gnu -lssl -lcrypto' ./configure -prefix "/usr/local/tdesktop/Qt-5.6.0" -release -force-debug-info -opensource -confirm-license -qt-zlib -qt-libpng -qt-libjpeg -qt-freetype -qt-harfbuzz -qt-pcre -qt-xcb -qt-xkbcommon-x11 -no-opengl -no-gtkstyle -static -openssl-linked -nomake examples -nomake tests
make -j4
sudo make install

building (make command) will take really long time.

####Google Breakpad

In Terminal go to /home/user/TBuild/Libraries and run

git clone https://chromium.googlesource.com/breakpad/breakpad
git clone https://chromium.googlesource.com/linux-syscall-support breakpad/src/third_party/lss
cd breakpad
./configure
make
sudo make install

###Building Telegram codegen utilities

In Terminal go to /home/user/TBuild/tdesktop and run

mkdir -p Linux/obj/codegen_style/Debug
cd Linux/obj/codegen_style/Debug
/usr/local/tdesktop/Qt-5.6.0/bin/qmake CONFIG+=debug ../../../../Telegram/build/qmake/codegen_style/codegen_style.pro
make
mkdir -p ../../codegen_numbers/Debug
cd ../../codegen_numbers/Debug
/usr/local/tdesktop/Qt-5.6.0/bin/qmake CONFIG+=debug ../../../../Telegram/build/qmake/codegen_numbers/codegen_numbers.pro
make

###Building Telegram Desktop

  • Launch Qt Creator, all projects will be taken from /home/user/TBuild/tdesktop/Telegram
  • Tools > Options > Build & Run > Qt Versions tab > Add > File System /usr/local/tdesktop/Qt-5.6.0/bin/qmake > Qt 5.6.0 (Qt-5.6.0) > Apply
  • Tools > Options > Build & Run > Kits tab > Desktop (default) > change Qt version to Qt 5.6.0 (Qt-5.6.0) > Apply
  • Open MetaLang.pro, configure project with paths /home/user/TBuild/tdesktop/Linux/DebugIntermediateLang and /home/user/TBuild/tdesktop/Linux/ReleaseIntermediateLang and build for Debug
  • Open Telegram.pro, configure project with paths /home/user/TBuild/tdesktop/Linux/DebugIntermediate and /home/user/TBuild/tdesktop/Linux/ReleaseIntermediate
  • Modify Telegram.pro
    • find #xkbcommon and uncomment it
    • find LIBS += /usr/local/lib/libxkbcommon.a and comment (#) it
  • Build Telegram.pro for Debug, if GeneratedFiles are not found click Run qmake from Build menu and try again
  • If there is an error for av_warn_unused_result, go to the header file and comment out it
  • Open Updater.pro, configure project with paths /home/user/TBuild/tdesktop/Linux/DebugIntermediateUpdater and /home/user/TBuild/tdesktop/Linux/ReleaseIntermediateUpdater and build for Debug
  • Release Telegram build will require removing CUSTOM_API_ID definition in Telegram.pro project and may require changing paths in /home/user/TBuild/tdesktop/Telegram/FixMake.sh or /home/user/TBuild/tdesktop/Telegram/FixMake32.sh for static library linking fix, static linking applies only on second Release build (first uses old Makefile)

###Modify Font Setting

Because there are more issues for changing fonts, and there is no improvement for this, so the following is the dirty methods for changing fonts settings.

####Change Fonts

  • Prepare 3 ttf fonts which you want to change for, one for reqular (let it as a-regular.ttf), another for semibold (let it as a-semibold.ttf), and the last for bold (let it as a-bold.ttf)
  • Find the ttf`s font family name (let them as a, a semibold, and a bold)
  • Open Telegram.pro and modify it

    • Delete resources for origional fonts, at Resource > Resources > telegram.qrc > /gui > art > OpenSans-Regular.ttf, OpenSans-Bold.ttf, OpenSans-Semibold.ttf

    • Modify Source Code > SourceFiles > ui > twidget.cpp, it will make Telegram load the fonts which are the same path as Telegram app.

         //QFontDatabase::addApplicationFont(qsl(":/gui/art/fonts/OpenSans-Regular.ttf"));
   //QFontDatabase::addApplicationFont(qsl(":/gui/art/fonts/OpenSans-Bold.ttf"));
   //QFontDatabase::addApplicationFont(qsl(":/gui/art/fonts/OpenSans-Semibold.ttf"));
     QFontDatabase::addApplicationFont("./a-regular.ttf");
     QFontDatabase::addApplicationFont("./a-bold.ttf");
     QFontDatabase::addApplicationFont("./a-semibold.ttf");

    • Replace all project files for Open Sans SemiBold to a semibold

    • Replace all project files for Open Sans to a

  • Rebuild Telegram.pro
