Fedora Core 14 to 20

Fedora Core home page: http://fedoraproject.org

Linux Installation Hints:

• Packages: in addition to Fedora's default suggestions and your choices, check/install following packages (required for development only, except where noted):
  
• Software Development (or PkgCollection: Development Tools and Development Libraries)
• Editors
• tcsh and xterm (for Terminal i/o mode, required also for executables)
• libjpeg-static-* library (required for building static executables, search for by "libjpeg" in Search/Description)
• static C libraries (required for building static executables, search for by "libc" in Search/Description)
• libX11-devel-* library (optional, required only for building self-contained static executables)
   
• For 32-bit Fedora distribution, you may install all required packages by executing
  su ; yum install gcc gcc-c++ glibc-devel glibc-static libstdc++-static libSM-devel libjpeg libjpeg-turbo-static libX11-devel libXext-devel libXft libICE-devel SDL-static tcsh
   
• For 64-bit Fedora distribution, you will additionally need standard 32bit packages. They are available in http://download.fedora.redhat.com/pub/fedora/linux/releases/REL/Everything/i386/os/Packages (where the REL is your current Fedora release, e.g. 16). To fetch these packages automatically by yum, either issue
  su ; yum-config-manager --add-repo=yum-config-manager
  --add-repo=http://download.fedoraproject.org/pub/fedora/linux/releases/REL/Everything/i386/os/
  where REL is your current Fedora version, e.g. 14, 15, 16 or 18
   
  or add following section in the file /etc/yum.repos.d/fedora.repo :
   
    [fedora-i686]
    name=Fedora $releasever - $basearch - i386
    failovermethod=priority
    baseurl=http://download.fedoraproject.org/pub/fedora/linux/releases/$releasever/Everything/i386/os/
    mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=i386
    enabled=1
    metadata_expire=7d
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-i386
   
  and then execute
   
  su ; yum install gcc gcc-c++ glibc-devel.i686 libstdc++ glibc-static.i686 libstdc++-devel.i686 libjpeg libjpeg-turbo-static.i686 libICE libICE-devel.i686 libSM libSM-devel.i686 libX11 libX11-devel.i686 libXext libXext-devel.i686 libXft SDL-static.i686 tcsh fontconfig.i686 libXft.i686 libXft-devel.i686 libXrender.i686
   
  See also this 64bit info for further information. Since 32bit libs are available in Fedora per default in /usr/lib (and 64bit libs in /usr/lib64), you don't need to change the -L path nor anything else in the /usr/local/FlagShip7/FS7config file.

Installation of Visual FlagShip 7.1.* (VFS7):

• Install the .rpm based package FlagShip-7*.rpm, see the booklet for details and step-by-step instruction. If the rpm installer reports unresolved dependency libjpeg.so, install package libjpeg-turbo and libjpeg-turbo-static (check for i686 version by "yum provides libjpeg-turbo").
• The main FlagShip directory is /usr/local/FlagShip7
• Fedora may supply all required static libraries in packages suggested above, so you may compile both dynamically (default) and statically (using the -stat compiler switch). If you get get some warnings at the end of FlagShip installation, or linker errors at static linking, post-install the required packages noted above from the Fedora distribution.
• You may ignore the message "could not locate static X11 library..." from FlagShip installer, however the static libX11.a is available here.

Using FlagShip:

• Read the short step-by-step instruction for using FlagShip in the booklet (available also in the main /usr/local/FlagShip7 directory)
• If in X/GUI environment (KDE, Gnome etc): open console/terminal window.
• To test and run supplied examples, invoke  cd /usr/local/FlagShip7/examples ; make
• If you get message "error while loading shared libraries ... cannot restore segment prot after reloc: Permission denied" at the time of executing the application, you will need to set SELinux security context for shared FlagShip library, see "Installation" paragraph above.
• Compile your sources as described in fsman section FSC, e.g. "FlagShip myapp*.prg", a short help is available via "FlagShip -h". Note the case sensitive names in Unix/Linux.
• Watch for displayed compiler and linker errors, and fix if any.
• If everything is ok, execute (see fsman section FSC):
  ./a.out            # in GUI mode
  newfswin ./a.out   # for Textual i/o mode in X11 environment
• In some Fedora packages, you may need to disable line 416 (#xrdb -merge ...) and enable line 419 (source $FlagShipDir/bin/$xmapFile) in /usr/local/FlagShip6/bin/newfswin to proper support Terminal i/o in X11 environment.
• The on-line manual is available by entering "fsman &" in KDE/Gnome console for GUI mode, or "newfswin fsman" for textual mode. Printable manual in pdf format is available in /usr/local/FlagShip7/manual or in Web.
• Step-by-step instruction for converting available applications to GUI is given in fsman section LNG.9.6
• Examples are available in /usr/local/FlagShip7/examples (simply invoke "make" and "make terminal" there), as well as in the /usr/local/FlagShip6/tools directory (read the *.txt info files there). Best to copy them to your working directory when you wish to modify the source.
• You may use the FlagShip's distribute.sh script to customize all redistributable files with your application.
• On problems or questions, please check the on-line manual and FAQ first. If your problem persist, contact FlagShip support - we grant free tech support not only for the licensed, but also for the Test/Eval version.

Known Issues :

• If the PC-8 semi-graphic characters are displayed in textual mode as Ä's (A-umlaut) etc, you eiter may either
  - start the application via newfswin, newfscons or newfsterm (see above and Release Notes in fsman) which automatically sets the proper environment, or
  - disable Unicode i.e. set the environment variable "LANG=en_EN", and start the application via newfswin.
  See also and/or test with /usr/local/FlagShip6/examples/boxcommand.prg


• If the last character in the manual pages seems to be missing in GUI mode, select Courier[adobe] via Menu→Options→Font→Input/Output or assign other font via command-line parameter, see fsman -h for furtehr details.


• If you have enabled new kernel security extensions from the SELinux project (default since Fedora 7), and get "error while loading shared libraries: /usr/lib/libFlagShip6.so: cannot restore segment prot after reloc: Permission denied" at the time of invoking dynamically linked executable, you will need to enable security context for your shared FlagShip library by issuing :
  su -c "chcon -t textrel_shlib_t /usr/local/FlagShip7/lib/libFlagShip7*.so"
  or disabling SELinux altogether in your /etc/sysconfig/selinux file by setting the line SELINUX=disabled


• When compiling large sources, you may get compiler error "** Warning: C compiler not invoked" but without any displayed syntax error. This is caused by insufficient stack size (stack overflow in yacc/lex parser) for large source files or many continuation statements (check the displayed source code line). You may increase the stack by e.g. "uname -s 30000". If you get here a message "ulimit: stack size: cannot modify limit..." you need to set (as su/root/sudo) "uname -Hs 30000", then re-open the user terminal, and set "uname -s 30000" anew. You may add this also in your ~/.bashrc script for an automatic set at login.

Additional Info:

Since FlagShip translates the Xbase code to C code as an intermediate step and requires object compatible libs during the linking stage, C compilers, utilities and libraries must be chosen with great care, otherwise upredictable errors may occur.

The C compiler (and the optional static libs) is required only in the developing phase, it is not required for the user of your application, which only needs the by FlagShip produced executable (i.e. your own application executables, see also fsman section SYS.1.2 for distribution hints).
