# U++ POSIX/X11 installation Standard POSIX/X11 distribution of U++ comes as a source tarball. If you want to run U++ graphical environnement (theide) or run U++ command line tool (umk), you will first need to compile and install U++. ## Build Requires Before compiling U++ source code, you must install a few developpement packages. Many POSIX/X11 distributions provides developpement packages with the same names. Sometimes, developpement package names don't match. You will have to find the corresponding names for your distribution. ### Build requires per distribution #### Debian/apt-get based distributions Build requires: g++ make libgtk-3-dev libnotify-dev libbz2-dev sox How to install them: if sudo is available and enabled on your distribution, copy/paste this in a terminal: ``` sudo apt-get install g++ make libgtk-3-dev libnotify-dev libbz2-dev sox ``` if sudo is not available: ``` su -c 'apt-get install g++ make libgtk-3-dev libnotify-dev libbz2-dev sox' ``` The 'buildrequires.debian' file in U++ tarball contains apt-get commands to do the same thing. You can use this file by running 'sh buildrequires.debian' as root (e.g. 'sudo sh buildrequires.debian' if sudo is available or 'su -c "sh buildrequires.debian"' if not). #### Fedora based distributions Build requires: gtk3-devel pango-devel atk-devel cairo-devel libnotify-devel bzip2-devel xorg-x11-server-devel freetype-devel expat-devel How to install them: if sudo is available and enabled on your distribution, copy/paste this in a terminal: ``` sudo yum install gtk3-devel pango-devel atk-devel cairo-devel libnotify-devel bzip2-devel xorg-x11-server-devel freetype-devel expat-devel ``` if sudo is not available: ``` su -c 'yum install gtk3-devel pango-devel atk-devel cairo-devel libnotify-devel bzip2-devel xorg-x11-server-devel freetype-devel expat-devel' ``` The 'buildrequires.fedora' file in U++ tarball contains yum commands to do the same thing. You can use this file by running 'sh buildrequires.fedora' as root (e.g. 'sudo sh buildrequires.fedora' if sudo is available or 'su -c "sh buildrequires.fedora"' if not). #### Other rpm based distributions Redhat 7 build requires: gtk3-devel pango-devel atk-devel cairo-devel libnotify-devel freetype-devel expat-devel bzip2-devel OpenSuse build requires: gtk3-devel pango-devel atk-devel cairo-devel libnotify-devel xorg-x11-devel freetype2-devel libexpat-devel libbz2-devel #### BSD based distributions Build requires: bash gmake gtk3 freetype2 libnotify clang-devel (e.g. clang++) How to install them: if sudo is available and enabled on your distribution, copy/paste this in a terminal: ``` sudo pkg install bash gmake gtk3 freetype2 libnotify clang-devel ``` if sudo is not available: ``` su -m root -c 'pkg install bash gmake gtk3 freetype2 libnotify clang-devel' ``` ## Compile U++ source code ### Standard U++ compilation First, uncompress U++ source tarball and change dir to the new created directory. Example: for upp-x11-src-**10641**.tar.gz ``` version=10641 tar zxvf upp-x11-src-$version.tar.gz cd upp-x11-src-$version ``` Use 'make' to compile U++ and generate theide (U++ integrated development environment) and umk (commandline tool for building U++ projects) then run 'make install' to prepare standard U++ environment: ``` make make install ``` Now you can start playing with U++ by invoking ~/theide. You might want to put theide and umk elsewhere later, e.g. inside ~/bin/ for example If you only want to build umk or theide, run make with the corresponding target: ``` make umk # or make theide ``` Note: 'make install' copy theide and umk in your home directory but it also: * create ~/upp directory to store U++ library sources and copy the U++ sources inside * create ~/upp/MyApps to store your application sources * create ~/upp.out as output for intermediate files * set up a few variables in the '~/.upp' directory. Those variables are required by umk and theide ## Advanced installation You can install umk and theide like most other POSIX project do. If make detects that you has defined the prefix variable, it will switch to standard POSIX installation mode. ``` make make install prefix="/usr" ``` You can also use several other standard installation variables in this installation mode: 'DESTDIR', 'bindir', 'datadir', 'mandir', and 'docdir'. ## Troubleshooting If your POSIX/X11 distribution use an old gcc version (< 4.9), U++ compilation will fail because of missing gcc c++11 standard implementation. To solve this, you need to install and use clang++ compiler instead of g++. Make search for g++ first and if gcc version is too old, it will automatically search for clang++ and then for any compiler named 'c++'. If you still need to force clang++ as default compiler or if clang++ is not in your path or if you want to use another compiler, you can run make with the CXX parameter. Example: ``` make CXX="/home/user/my-clang-install-dir/clang++" make install ``` On BSD based distributions, if you use make instead of gmake, U++ compilation will fail because BSD 'make' needs four dollars ('$$$$') to escape one. To solve this, you can install gmake or you can run make with an extra parameter if you use a recent U++ snapshot. Example (for bash shell): ``` make 'Dollar=$$$$' make install ``` Those file names are already escaped for gmake. This is why they already use two dollars (Dollar = $$). ## U++ spec file for rpm based distribution There is an alternative way to build U++ on rpm based distributions. Indead, U++ POSIX/X11 tarball contains a spec file for you to build a standard rpm binary and source file. To do that, first install U++ build requires and rpm-build then build U++. ### Fedora based distributions if sudo is available and enabled on your distribution, copy/paste this in a terminal: ``` sudo yum install gtk3-devel pango-devel atk-devel cairo-devel libnotify-devel bzip2-devel xorg-x11-server-devel freetype-devel expat-devel sudo yum install rpm-build version=10641 rpmbuild -ta upp-x11-src-$version.tar.gz ``` if sudo is not available: ``` su -c 'yum install gtk3-devel pango-devel atk-devel cairo-devel libnotify-devel bzip2-devel xorg-x11-server-devel freetype-devel expat-devel' su -c 'yum install rpm-build' version=10641 rpmbuild -ta upp-x11-src-$version.tar.gz ``` Note : the rpm binary doesn't install U++ source in your home directory nor does it create needed configuration for U++ command line tool (umk) after installation. Theide will take care of all this on first start.
