Building on GNU/Linux

This guide explains how to compile Starviewer 0.13 from scratch on a Debian GNU/Linux 8.2 amd64. (With 4GiB of RAM)

This guide avoids splattering files everywhere of your system, the only system wide changes will be a few 'apt-get install libsomething-dev'. We promise it :)

Installation can be made system wide, but optionally we show how to compile using a local directory in your home. On the example this directory is located on '~/uroot'.

'~/uroot' is just a prefix, if you replace it by '/' and run it as root then it will become a system wide setup.

Getting started: the quick way

  1. Use the script 'buildall.sh' to do the explained steps automatically. Remember to install Qt on the proper location (the script will tell you).

  2. To customize the default paths edit 'sdk/config/setup.sh'

  3. Install dependencies if necessary (see 'system dependencies') section.

  4. Once the SDK is compiled it will build Starviewer, however you may want to set up the QtCreator IDE. Then copy the environment variables and follow the instructions of the section 'Setting up QtCreator'.

  5. Run Starviewer.

Running Starviewer

Unless you have compiled and installed the SDK system-wide, Starviewer binary will be unable to find your compiled SDK libraries.

You must run the binary with the LD_LIBRARY_PATH environment variable set.

For the sake of convenience, on the compiled binary folder 'starviewer/bin/' create a file named starviewer.sh with the following contents:

#!/bin/bash
DIR=$(readlink -f $(dirname $BASH_SOURCE))
LD_LIBRARY_PATH=~/uroot/usr/local/lib:~/uroot/usr/local/lib/x86_64-linux-gnu:~/uroot/usr/local/lib/Qt5.4.1/5.4/gcc_64/lib/ $DIR/starviewer "$@"

Then make this file executable

chmod u+x starviewer.sh

Building the SDK

Libraries directory

  1. Run the Qt setup and set the installation path to '~/uroot/usr/lib/Qt5.4.1/'.

  2. Extract the downloaded library sources on (discarding Qt): '~/uroot/usr/local/src/'

  3. Copy 'extra-cmake-modules-1.3.0' inside 'threadweaver-5.3.0 directory'.

Configure

Edit the '/scripts/linux/config/setup.sh'

  • DOWNLOAD_PREFIX=~/uroot/downloads

    Where buildall.sh downloads the libraries

  • SDK_INSTALL_PREFIX=~/uroot/usr/local

    Where to install the SDK libraries once compiled

  • INSTALL_QTDIR=$SDK_INSTALL_PREFIX/lib/Qt5.4.1

    Only used to tell the user where to install Qt on buildall.sh

  • QTDIR=$SDK_INSTALL_PREFIX/lib/Qt5.4.1/5.4/gcc_64

    If you use a local Qt installaton, the path where it is installed

  • STARVIEWER_SOURCE_DIR_BASE=$SCRIPTS_ROOT/../../../starviewer

    Starviewer source code location

  • SOURCE_DIR_BASE=$SDK_INSTALL_PREFIX/src

    Location of SDK sources to build

  • PATCHES_ROOT=$SCRIPTS_ROOT/../../patches

    Location of the pathes to apply on SDK libraries

  • LD_LIBRARY_PATH=$SDK_INSTALL_PREFIX/lib

    Because SDK libraries binares are not on a standard location. This environment variable has to be set when starting starviewer binary or when you compile it. (if not the linker will fail).

Building Starviewer

In this contained installation we use several environment variables to configure the paths of the libraries and include files. During the build of the SDK the build script outputted a list of environment variables, which are read by the Starviewer .pro files.

If you paste the variables into the console, then you can just run QMake on Starviewer source directory and compilation will begin.

Most important variables are:

  • LD_LIBRARY_PATH

    Has to be set during linking and when running Starviewer binary, because library binares are not in a system path, we must tell where are they.

  • QTDIR

    Path to the custom Qt installation prefix.

  • SDK_INSTALL_PREFIX

    Used on defaultdirectories.pri and is used to tell where are the library binaries and include files.

The project main file is located in 'starviewer/starviewer.pro'

If you want to customize where the SDK libraries are placed or use the system ones edit 'starviewer/starviewer/src/defaultdirectories.pri'

Step by step build

  1. Export this environment variables. You should have copied them on your clipboard.

    export SDK_INSTALL_PREFIX
    export LD_LIBRARY_PAYH
    export QTDIR
    
  2. Run QMake on Starviewer directory (do not use the absolute path $QTDIR if you want to use the Qt libraries installed on your system).

    $QTDIR/bin/qmake starviewer.pro -r -spec linux-g++
    
  3. Compile

    make -j4
    
  4. Make a launch script on 'starviewer/starviewer/bin/starviewer.sh' with:

    #!/bin/bash
    DIR=$(readlink -f $(dirname $BASH_SOURCE))
    LD_LIBRARY_PATH=[PUT YOUR LD PATH HERE]  $DIR/starviewer "$@"
    

    Replace [PUT YOUR LD PATH HERE] with the real LD path, outputted by the build script, you should have it in your clipboard.

Setting up QtCreator

  1. Open the starviewer project (starviewer.pro).

  2. Tools > Options > Build & run > Qt Versions

    Check that the local Qt installation is autodetected, if not add it manually.

  3. Tools > Options > Build & run > Kits

    Add the kit for the installed Qt version if it's not autodetected.

  4. Switch to 'Projects' section (Ctrl+5).

  5. Add kit > Desktop Qt 5.4.1 GCC 64bit

  6. Disable 'shadow build'

  7. Build Steps > Make > Make arguments

    Add -j4 to increase the compilation speed.

  8. Build environment > Batch edit...

    Paste the variables you were told to copy after building the SDK.

    You must at least have SDK_INSTALL_PREFIX and LD_LIBRARY_PATH. Optionally you can skip the others, as they are not currently used.

  9. Build the project (Ctrl+B)

  10. Run Starviewer (Ctrl+R)

Troubleshooting

SDK compilation failure

  • If an SDK library fails to compile, re-run the build.sh or buildall.sh script again without deleting or cleaning the SDK building directories.

  • Check that you have the system libraries installed (apt-get install...)

  • Check that you do not have paths with spaces.

Starviewer compilation failure

  • I get errors with missing translations. Run this on your project directory.

    find  -name '*.pro' -exec lrelease {} \;
