Installation Instructions
*************************

For Debian based GNU / Linux
============================
Tested development platform: Ubuntu 14.4 amd64.

The following commands build qt5 and polarssl which are dependencies of the Software.
To only build for the amd64 platform omit the i386 instructions.

For build dependencies please refer to the Qt documentation 
( qtbase/src/plugins/platforms/xcb/README ).
Polarssl needs cmake and build-essentials.

    export YOURPREFIX=<Prefix of your choice (default /usr)>
    export PATH=$YOURPREFIX/bin:$PATH

    curl https://download.qt-project.org/official_releases/qt/5.3/5.3.1/single/qt-everywhere-opensource-src-5.3.1.tar.xz.mirrorlist | grep SHA-256

    tar -xf qt-everywhere-opensource-src-5.3.1.tar.xz

    cd qt-everywhere-opensource-src-5.3.1/qtbase

build dependencies have to to be installed at this point,

    make && make test && make install

To compile the software you can use plain cmake. An out of source build is
highly suggested. For build options see CMakeList.txt

    hg clone https://wald.intevation.org/hg/trustbridge/
    cd trustbridge
    hg clone https://wald.intevation.org/hg/trustbridge/nss-cmake-static
    mkdir build-linux
    cd build-linux
    cmake .. -DCMAKE_PREFIX_PATH=$YOURPREFIX


I386
====
Install dependencies (list might be incomplete)
    apt-get install libx32stdc++-4.8-dev libc6:i386 g++-4.8-multilib \
   libxcb1:i386 libxcb1-dev:i386 libx11-xcb1:i386 libx11-xcb-dev:i386 libxcb-keysyms1:i386 \

   libsm-dev:i386 libnss3-dev:i386

Create a new directory for qt. As qt has to build in source you need a different
directory.
    mkdir i386
    cd i386
    tar -xf ../qt-everywhere-opensource-src-5.3.1.tar.xz
    cd qt-everywhere-opensource-src-5.3.1/qtbase/
    ./configure --prefix=$YOURPREFIX/i386 \
    -opensource -platform linux-g++-32 \
    -release  -nomake tests  -nomake examples  -confirm-license \
    -static -no-cups -no-nis -no-icu \
    -no-directfb -no-opengl -no-kms -no-eglfs -no-egl -no-openssl -no-glib \
    -system-libpng -qpa xcb -qt-xcb -no-nis -no-libjpeg -no-gif -qt-zlib \
    -no-fontconfig -qt-freetype -qt-libpng -qt-xkbcommon \
    && \
    nice make -j`nproc` && \
    make install

Switch back to the polarssl directory
    cd ../../../polarssl-1.3.8/
    mkdir build-i386
    cd build-i386
    cmake .. -DCMAKE_C_FLAGS="-fpic -m32" -DCMAKE_INSTALL_PREFIX=$YOURPREFIX/i386 \
         -DCMAKE_VERBOSE_MAKEFILE=True \
         -DENABLE_TESTING=FALSE -DENABLE_PROGRAMS=FALSE && \
    nice make -j`nproc` && \
    make install

Now for Trustbridge itself
    cd ../../trustbridge
    mkdir build-i386
    cd build-i386
    cmake .. -DCMAKE_PREFIX_PATH="$YOURPREFIX/i386" \
    -DCMAKE_VERBOSE_MAKEFILE=True \
    -DCMAKE_C_FLAGS=-m32 \
    -DCMAKE_CXX_FLAGS="-m32"

Hiawatha (for Downloader unit test)
===================================
Hiawatha is used in the downloader unit tests to provide a testbench
for the ssl connection. To build it you may need libxslt-dev as additional
dependency.

    wget https://www.hiawatha-webserver.org/files/hiawatha-9.5.tar.gz
    sha256sum hiawatha-9.5.tar.gz

c181011db1af187006190fc186689a0707a6f1e7b524c2a4347840e8fdf68b4f  hiawatha-9.5.tar.gz

    tar -xf hiawatha-9.5.tar.gz
    cp polarssl-1.3.7-gpl.tgz hiawatha-9.5/polarssl/polarssl.tgz
    cd hiawatha-9.5/polarssl
    sed -i 's/wget.*//' upgrade
    ./upgrade 1.3.7
    cd ..
    mkdir build
    cd build
    cmake .. -DCMAKE_INSTALL_PREFIX=$YOURPREFIX
    make && make install

Osslsigncode (for binverify unit test)
======================================
Osslsigncode is used to create PKCS#7 embedded signatures for Windows Authenticode
it is needed for the Windows part of the binverify unit test on the build system.

    wget http://downloads.sourceforge.net/project/osslsigncode/osslsigncode/osslsigncode-1.7.1.tar.gz
    sha256sum osslsigncode-1.7.1.tar.gz
# f9a8cdb38b9c309326764ebc937cba1523a3a751a7ab05df3ecc99d18ae466c9
    tar -xf osslsigncode-1.7.1.tar.gz
    cd osslsigncode-1.7.1
    ./configure --without-curl --prefix=$YOURPREFIX
    make && make install

    # for a windows binary (optional)
    OPENSSL_CFLAGS=-I$MXETARGET/include OPENSSL_LIBS="-L$MXETARGET/lib -lcrypto -lz -lgdi32" ./configure --without-curl --host=i686-w64-mingw32 --prefix=$MXETARGET

For Microsoft Windows
=====================
The Windows variant can be cross compiled on Debian based GNU / Linux systems.
The minimum requirement is Debian stable.
Tested development platform: Ubuntu 13.10.

Dependencies on the Host system:
    git autoconf automake bash bison bzip2 \
    cmake flex gettext git g++ intltool \
    libffi-dev libtool libltdl-dev libssl-dev \
    libxml-parser-perl make openssl patch perl \
    pkg-config scons sed unzip wget xz-utils autopoint \
    gperf

Build the windows binaries:
    MXEPATH=$YOURPREFIX/win
    git clone https://github.com/mxe/mxe.git $MXEPATH
    cd $MXEPATH
    echo "MXE_TARGETS := i686-w64-mingw32.static" > settings.mk
    make polarssl
    make qtbase

Workaround Qt CMake Bugs:
    find $MXEPATH/usr/i686-w64-mingw32.static/qt5/lib/cmake -name \*.cmake | \
        xargs sed -i 's/\/\([a-z]*\)\.lib/\/lib\1\.a/g'
    sed -i 's/^_qt5gui_find_extra_libs.*//' \
        $MXEPATH/usr/i686-w64-mingw32.static/qt5/lib/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake

Make an NSS build available in the MXE prefix:
    # TODO -> Document how to build NSS,..
    cp -r <magic nss folder> $MXEPATH/usr/i686-w64-mingw32.static/

Compile the software:
    cd trustbridge
    mkdir build-windows
    cd build-windows
    MXETARGET=$MXEPATH/usr/i686-w64-mingw32.static/
    cmake .. \
        -DCMAKE_PREFIX_PATH="$MXETARGET/qt5;$MXETARGET;" \
        -DCMAKE_TOOLCHAIN_FILE="$MXETARGET/share/cmake/mxe-conf.cmake" \
        -DCMAKE_VERBOSE_MAKEFILE=True

Runtime Depdendencies
=====================
The Admin tool needs some additional software to be able to create installtion
packages:

    apt-get install nsis wine sharutils
