U++ POSIX/X11 Tarball Installation

Standard POSIX/X11 distribution of U++ comes as a source tarball. If you want to run U++ graphical environment (theide) or run U++ command line builder (umk), you will first need to compile and install U++.

1. Build Requirements

Before compiling U++ source code, you must install a few development packages. Many POSIX/X11 distributions provides development packages with the same names. Sometimes, development 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  libgtk2.0-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:

if sudo is not available:

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:  gtk2-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:

if sudo is not available:

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:  gtk2-devel pango-devel atk-devel cairo-devel libnotify-devel freetype-devel expat-devel bzip2-devel

OpenSuse build requires: gtk2-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 gtk2 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:

if sudo is not available:

2. 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):

Use 'make' to compile U++ and generate theide (U++ integrated development environment) and umk (command line tool for building U++ projects) then run 'make install' to prepare standard U++ environment:

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

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

If you only want to build umk or theide, run make with the corresponding target:

3. 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. Example:

You can also use several other standard installation variables in this installation mode: 'DESTDIR', 'bindir', 'datadir', 'mandir', and 'docdir'.

4. Additional dependencies

4.1 OpenGL

To develop application that needs to use 3D graphics you should download following packages for your distribution:

5. Troubleshooting

Compilation doesn't work, because I have old compiler version. What should I do?

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:

I use make on BSD operating like system and the compilation fail. What should I do?

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):

Those file names are already escaped for gmake. This is why they already use two dollars (Dollar = $$).

I compiled my app, but the debugger (GDB) doesn't start. How can I fix this?

You should install GDB package and make sure it is in your system path. You can check if it is install correctly by running following command in your terminal:

It should returns valid GDB path like '/usr/bin/gdb'.

6. U++ spec file for rpm based distribution

There is an alternative way to build U++ on rpm based distributions. Indeed, 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 (don't forget to modify the version number accordingly):

If sudo is not available:

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.
