The Symbol font and the Zapf Dingbats font do not work on X11. This is correct behavior for UTF-8 platforms. 2 PREREQUISITES ================== 2.1 Ubuntu 10 ---------------- Ubuntu Linux can be downloaded here: http://www.ubuntu.com/ If you have not done so yet, download and install Ubuntu. Open a shell and install some software: sudo apt-get install g++ sudo apt-get install gdb sudo apt-get install subversion sudo apt-get install autoconf sudo apt-get install libx11-dev sudo apt-get install libglu1-mesa-dev These two are optional, but highly recommended: sudo apt-get install libasound2-dev sudo apt-get install libxft-dev If you are planning to use the Code::Blocks IDE, also install this sudo apt-get install codeblocks I like to use subversion to install the latest FLTK-1.3.release: svn co http://seriss.com/public/fltk/fltk/branches/branch-1.3/ fltk-1.3 To update to the latest version, just go into the fltk-1.3 directory and type svn update 2.2 Linux Mint 9 ------------------- Linux Mint 9 can be downloaded here: http://www.linuxmint.com/ If you have not done so yet, download and install Linux Mint. Open a shell and install some software: sudo apt-get install g++ sudo apt-get install gdb sudo apt-get install subversion sudo apt-get install autoconf sudo apt-get install libx11-dev sudo apt-get install libglu1-mesa-dev These two are optional, but highly recommended: sudo apt-get install libasound2-dev sudo apt-get install libxft-dev If you are planning to use the Code::Blocks IDE, also install this sudo apt-get install codeblocks I like to use subversion to install the latest FLTK-1.3.release: svn co http://seriss.com/public/fltk/fltk/branches/branch-1.3/ fltk-1.3 To update to the latest version, just go into the fltk-1.3 directory and type svn update FIXME: no FL_SYMBOL font (-*-symbol-*), font 15 (Zapf-Dingbats) 2.3 Fedora 13 ------------------- Fedora 13 Linux can be downloaded here: http://fedoraproject.org/ If you have not done so yet, download and install Fedora. Open a terminal window and install some software. In Fedora, the default user has no permission to call "sudo", so we will change user a few times: su root yum groupinstall "Development Tools" yum groupinstall "X Software Development" yum groupinstall "C Development Tools and Libraries" If you are planning to use the Code::Blocks IDE, also install this yum install codeblocks.i686 (for 64 bit machines) Don't forget to leave root status (Ctrl-D) before loading FLTK. To install FLTK for every user, you either have to set root user again, or use "visudo" to add yourself to the "sudo" list. I like to use subversion to install the latest FLTK-1.3.release: svn co http://seriss.com/public/fltk/fltk/branches/branch-1.3/ fltk-1.3 To update to the latest version, just go into the fltk-1.3 directory and type svn update FIXME: no FL_SYMBOL font (-*-symbol-*), font 15 (Zapf-Dingbats) 2.8 SunOS / Solaris ---------------------- SunOS is a commercial operating system from Sun Microsystems (in 2009 the company was sold to Oracle). SunOS is also called Solaris since version 5. There was an open source derivative called OpenSolaris (based on Solaris 10) that was cancelled by Oracle. The successor in spirit is called OpenIndiana and can be downloaded from here: http://www.openindiana.org/ For FLTK you need at least SunOS 5.7 (aka Solaris 7). This version supports 64 bit machines and POSIX threads. For machines with 64 bit SPARC processors it is highly recommended to use Sun compilers, the 64 bit code generated by older versions of GCC for such machines is unusable (expect something between horribly broken and immediate crash). Consider using pkgsrc with this operating system. See the NetBSD section if you want to do so. If you have GCC and Sun compilers installed, configure your environment like this to use the Sun compilers and pkgsrc graphics libraries: export CC="cc" export CXX="CC" export CPPFLAGS="-I/usr/pkg/include" export LDFLAGS="-L/usr/pkg/lib -R/usr/pkg/lib" To build a 64 bit FLTK library, add the following flags: export CFLAGS="-xarch=v9" export CXXFLAGS="-xarch=v9" 2.10 HP-UX ------------- HP-UX is a commercial operating system from HP, no free or open source derivatives are available. For FLTK you need at least HP-UX 11.11 and the latest patch bundles should be installed. Consider using pkgsrc with this operating system. See the NetBSD section if you want to do so. 2.11 AIX ----------- AIX is a commercial operating system from IBM, no free or open source derivatives are available. For FLTK you need at least AIX 5L, I have tested version 5.1 patched to ML9. Consider using pkgsrc with this operating system. See the NetBSD section if you want to do so. 2.12 NetBSD -------------- NetBSD can be downloaded here: http://www.netbsd.org/ If you have not done so yet, download and install NetBSD. Ensure that the optional distribution sets "comp" (Compiler, header files, development tools) and x*** (X Window System) are installed. Now install and configure pkgsrc. The current version can be downloaded here: http://www.pkgsrc.org/ To use the current stable version of FLTK, simply install it from pkgsrc: cd /usr/pkgsrc/x11/fltk13 bmake install For the latest development snapshot, first install the svn client from pkgsrc: cd /usr/pkgsrc/devel/subversion bmake install Now fetch the latest FLTK source code: svn co http://seriss.com/public/fltk/fltk/branches/branch-1.3/ fltk-1.3 To update to the latest version, just go into the fltk-1.3 directory and type svn update If you have installed JPEG and PNG libraries from pkgsrc, configure your environment as follows so that the FLTK configure script can find them: export CPPFLAGS="-I/usr/pkg/include" export LDFLAGS="-L/usr/pkg/lib" To install GNU autoconf from pkgsrc: cd /usr/pkgsrc/devel/autoconf bmake install 3 HOW TO BUILD FLTK USING GCC ================================ 3.1 Downloading and Unpacking -------------------------------- Download FLTK from here: https://www.fltk.org/software.php If you are familiar with "subversion" and like to stay current with your version, you will find the subversion access parameters at the bottom of that page. Unpack FLTK into a convenient location. I like to have everything in my dev directory: cd mkdir dev cd dev mv ~/Downloads/fltk-1.3.xxxx.tar.gz . tar xvfz fltk-1.3.xxxx.tar.gz cd fltk-1.3.xxxx 3.2 Configuring FLTK ----------------------- If you got FLTK via subversion then you need one extra step. Otherwise skip over this part. Stay in your FLTK source-code directory and type the following: NOCONFIGURE=1 ./autogen.sh Now configure your FLTK installation: ./configure ADVANCED: type "./configure --help" to get a complete list of optional configuration parameters. These should be pretty self-explanatory. Some more details can be found in README. :END_ADVANCED The configuration script will check your machine for the required resources which you should have installed as described in the Prerequisites chapter. Review the Configuration Summary, maybe take some notes. 3.3 Building FLTK -------------------- Now this is easy. Stay in your FLTK source-code directory and type: make The entire FLTK toolkit including many test programs will be built for you. No warnings should appear. If some do, please let the FLTK developer team know via the mailing list or the bug reporting template at www.fltk.org . Actually, as of Apr 13 2016, one or two warnings will show, mostly about deprecated declarations. Please ignore them. 3.4 Testing FLTK ------------------- After a successful build, you can test FLTK's capabilities: test/demo 3.5 Installing FLTK ---------------------- If you did not change any of the configuration settings, FLTK will be installed in "/usr/local/include" and "/usr/local/lib" by typing sudo make install If you are using the KDE, GNOME or XFCE desktop environments and want to call "fluid" from the desktop menu, you will need to install additional files and icons under "/usr/share" by typing: sudo make install-desktop It is possible to install FLTK without superuser privileges by changing the installation path to a location within the user account by adding the "--prefix=PREFIX" parameters to the "./configure" command. 3.6 Creating new Projects ---------------------------- FLTK provides a neat script named "fltk-config" that can provide all the flags needed to build FLTK applications using the same flags that were used to build the library itself. Running "fltk-config" without arguments will print a list of options. The easiest call to compile an FLTK application from a single source file is: fltk-config --compile myProgram.cxx "fltk-config" and "fluid" will be installed in "/usr/local/bin/" by default. I recommend that you add it to the command search path. 4 CREATING A NEW PROJECT IN CODE::BLOCKS =========================================== Code::Blocks is a free and popular C++ IDE in the Linux world. It also runs on OS X and Windows. Configured correctly, it can also cross-compile between these platforms. This chapter focuses on creating a new FLTK project for Linux, assuming that FLTK 1.3 was previously built and installed in its default location from the command line. If not done yet, install Code::Blocks as described in the Prerequisites chapter above, or download it from their web site. This description is based on version 10.05: http://www.codeblocks.org/ Start Code::Blocks. Select File > New > Project. In the "New from template" dialog box, click on "FLTK project" and follow the instructions. The default project supports basic fltk. If you would like to add support for images, OpenGL, GLUT, or Forms, add the corresponding flags --use-images, --use-gl, --use-glut, and --use-forms respectively. The flags are located in the "Project Build Options" dialog. To change the compiler flags, select your project in the tree view, then select the "Compiler Settings" tab, then "Other Options" and add the flags to `fltk-config --cxxflags` in front of the second "`". The linker flags are located in the "Linker Settings" tab under "Other Linker Options". Add the flags to `fltk-config --ldstaticflags` in front of the second "`". CodeBlocks can be set up to use fluid to manage modules. The following info is from mingodad@gmail.com posted on fltk.general 06/17/2013: """ I have these settings in codeblocks on linux: Settings -> Compiler and debugging settings -> Other settings -> Advanced options: -- Add an extension (in my case "fl") -- On command line macro: cd $file_dir; fluid -c $file -- Generated files (to be further compiled): $file_dir/$file_name.cxx $file_dir/$file_name.h Settings -> Environment -> Files extension handling : Wildcard : *.fl To open file: Launch an external program External program: fluid With that I can double click on any fluid file I include on a project and it opens with fluid. When I press "run" or "build" codeblocks calls fluid to generate the c++ files and compiles if needed.
