It is written on `CPP` using Qt library. The project is actively developed. In this paper I will say about building this package in Archlinux using Qt5 library (instead of Qt4 which is used in current AUR packages). # What's wrong? This package uses [qbs](//qt-project.org/wiki/qbs "Wiki") for building, which is a bit strange IMHO. A package, which is necessary for building, is [in AUR](//aur.archlinux.org/packages/qbs-git/ "AUR") . I recommend to use git version of the package. When I asked Andrea Scarpino (who maintains KDE and Qt packages into the official repos) about qbs, he told me "we will support it in time". And I agree with him, the project seems to be a little unstable. # Prepare Install dependences. I had used `namcap`, so maybe I missed something: ```bash pacman -Sy --asdeps clang git libc++abi qt5-quick1 qt5-x11extras yaourt -S --asdeps jreen-git qbs-git ``` ### qbs settings You may read about qbs [on the link](//qt-project.org/wiki/qbs "Wiki") or see examples which are provides by the package. qbs uses configuration file that firstly you must create and secondly it is stored in your home directory. In theory a configuration file creating (`~/.config/QtProject/qbs.conf`) looks like this: ```bash qbs-setup-qt --detect qbs-detect-toolchains ``` Firstly we find Qt libraries. Then we find toolchains (such as compilers). And next we must insert a toolchain into Qt profile (for example, we need `clang` toolchain): ```bash sed 's/clang\\/qt-5-2-0\\/g' -i ~/.config/QtProject/qbs.conf ``` And there are other ways. You may edit the file manually or use `qbs-config-ui` or `qbs-config`. So, we have created the configuration file and put it into build directory: ```ini [General] [Qt] filedialog= [profiles] clang\cpp\compilerName=clang++ clang\cpp\toolchainInstallPath=/usr/bin clang\qbs\architecture=x86_64 clang\qbs\endianness=little clang\qbs\toolchain=clang, llvm, gcc gcc\cpp\compilerName=g++ gcc\cpp\toolchainInstallPath=/usr/bin gcc\qbs\architecture=x86_64 gcc\qbs\endianness=little gcc\qbs\toolchain=gcc qutim\Qt\core\binPath=/usr/lib/qt/bin qutim\Qt\core\buildVariant=release qutim\Qt\core\config=shared, qpa, no_mocdepend, release, qt_no_framework qutim\Qt\core\docPath=/usr/share/doc/qt qutim\Qt\core\incPath=/usr/include/qt qutim\Qt\core\libInfix= qutim\Qt\core\libPath=/usr/lib qutim\Qt\core\mkspecPath=/usr/lib/qt/mkspecs/linux-g++ qutim\Qt\core\namespace= qutim\Qt\core\pluginPath=/usr/lib/qt/plugins qutim\Qt\core\qtConfig=minimal-config, small-config, medium-config, large-config, full-config, gtk2, gtkstyle, fontconfig, libudev, evdev, xlib, xcb-glx, xcb-xlib, xcb-sm, xrender, accessibility-atspi-bridge, linuxfb, c++11, accessibility, opengl, shared, qpa, reduce_exports, reduce_relocations, clock-gettime, clock-monotonic, mremap, getaddrinfo, ipv6ifname, getifaddrs, inotify, eventfd, system-jpeg, system-png, png, system-freetype, no-harfbuzz, system-zlib, nis, cups, iconv, glib, dbus, dbus-linked, openssl-linked, xcb, xinput2, alsa, pulseaudio, icu, concurrent, audio-backend, release qutim\Qt\core\version=5.2.0 qutim\cpp\compilerName=clang++ qutim\cpp\toolchainInstallPath=/usr/bin qutim\qbs\architecture=x86_64 qutim\qbs\endianness=little qutim\qbs\toolchain=clang, llvm, gcc ``` [qbs-qutim.conf](/resources/docs/qutim-qt5-git/qbs-qutim.conf "File") ### Patch for sources The first problem is `clang` (at least in Archlinux): ```diff diff -ruN qutim.orig/core/libqutim.qbs qutim/core/libqutim.qbs --- qutim.orig/core/libqutim.qbs 2014-01-06 15:39:56.000000000 +0400 +++ qutim/core/libqutim.qbs 2014-01-06 15:44:54.502175067 +0400 @@ -75,7 +75,7 @@ cpp.linkerFlags: { var flags = base; if (qbs.toolchain.contains("clang") && qbs.targetOS.contains("linux")) - flags = flags.concat("-stdlib=libc++ -lcxxrt"); + flags = flags.concat("-lc++abi"); return flags; } ``` And the second one is Vk plugin: ```diff diff -ruN qutim.orig/protocols/vkontakte/vreen/vreen.qbs qutim/protocols/vkontakte/vreen/vreen.qbs --- qutim.orig/protocols/vkontakte/vreen/vreen.qbs 2014-01-06 15:41:42.000000000 +0400 +++ qutim/protocols/vkontakte/vreen/vreen.qbs 2014-01-06 15:46:47.142178486 +0400 @@ -5,6 +5,7 @@ property string vreen_qml_path: "bin" property string vreen_lib_path: "lib" property string vreen_libexec_path: "lib" + property string lib_path: "lib" property string vreen_version_major: 1 property string vreen_version_minor: 9 ``` [qutim-qbs-1.1.patch](/resources/docs/qutim-qt5-git/qutim-qbs-1.1.patch "File") ### Get sources ```bash # clone repo git clone https://github.com/euroelessar/qutim # save qbs.conf mkdir -p .config/QtProject cp qbs-qutim.conf .config/QtProject/qbs.conf # create build directory mkdir build # update submodules cd qutim git submodule update --init --recursive # patch cd .. patch -p0 -i qutim-qbs-1.1.patch ``` ## Building ```bash cd qutim HOME=$(pwd) qbs -j $(nproc) -d ../build release profile:qutim ``` I want to create a universal recipe for the building, thus we must set `$HOME` directory. Flag `-j` means number of jobs, `-d` means build directory, `release` means building type (debug, release), `profile` is used profile, which is described in the configuration file. ## Installation ```bash HOME=$(pwd) sudo qbs install -d ../build --install-root "/usr" profile:qutim ``` We must set root directory (`--install-root`), because without this option the package will be installed into `/` (`/bin` and `/lib`). ## PKGBUILD ```bash pkgname=qutim-qt5-git _gitname=qutim pkgver=v0.3.1.967.gc56d61e pkgrel=1 pkgdesc="Multiplatform instant messenger (qt5 build).
