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 requirements are listed with corresponding apt-get command in the 'buildrequires.debian' file in the U++ tarball. You can install them using
|
sudo sh buildrequires.debian
|
|
Fedora/yum based distributions
Build requirements are listed with corresponding yum command in the 'buildrequires.fedora' file in the U++ tarball. You can install them using
|
sudo sh buildrequires.fedora
|
|
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 gtk2 freetype2 libnotify clang-devel
|
|
if sudo is not available:
|
su -m root -c 'pkg install bash gmake gtk2 freetype2 libnotify clang-devel'
|
|
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):
|
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 (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:
|
make umk
# or
make theide
|
|
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:
|
make
make install prefix="/usr"
|
|
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:
|
libgtkglext1-dev # Debian like 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:
|
make CXX="/home/user/my-clang-install-dir/clang++"
make install
|
|
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 ('$$$$') to escape one. To solve this, you can install gmake or you can run make with an extra parameter if you use a recent U++ snapshot. Example (for bash shell):
|
make 'Dollar=$$$$'
make install
|
|
Those file names are already escaped for gmake. This is why they already use two dollars (Dollar = $$).
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):
|
sudo yum install gtk2-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-$version.tar.gz
|
|
If sudo is not available:
|
su -c 'yum install gtk2-devel pango-devel atk-devel cairo-devel libnotify-devel bzip2-devel xorg-x11-server-devel freetype-devel expat-devel'
su -c 'yum install rpm-build'
version=10641
rpmbuild -ta upp-x11-src-$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.
