fpGUI Toolkit
INSTALLATION NOTES
Building fpGUI from the Command Line
====================================
This is still a work in progress until I can find a suitable solution. I'm
not 100% satisfied with this, but it's a quick and dirty way to get things
to compile. I'll assume you have the 'fpc' executable setup in your PATH so it
can be run from any location on your computer. I'll also assume your global
fpc.cfg file has been setup correctly so the FPC compiler can find the RTL and
FCL units.
Under Linux run:
cd <fpgui>/src
build.sh
Under Windows run:
cd <fpgui>\src
build.bat
The extrafpc.cfg file located in the src directory is combined with your global
fpc.cfg file. The local extrafpc.cfg file sets up all the required search and
include paths to compile the CoreLib and GUI directories.
All compiled units (*.o and *.ppu) are saved in the <fpgui>/lib directory. This
makes the search paths for you applications a little easier to setup.
Building fpGUI using Lazarus
============================
I use a Lazarus feature call Packages that compiles the required
units and keeps track of the compiled units and paths when creating
applications.
* Start Lazarus
* Select Components->Open Package File (*.lpk) and select the
src/corelib/<your platform>/fpgui_toolkit.lpk
Under Linux/FreeBSD the .lpk file will be in the 'x11' directory.
Under Windows the .lpk file will be in the 'gdi' directory.
A new dialog will appear - click Compile.
* Lazarus has now compiled the package and will keep track of
all the compiled units and paths.
* Now lets open a project. Select Project->Open Project and select
any project in the examples/gui directory. Select the *.lpi file.
* Now select Run->Build and Lazarus will compile the project for
you. The executable will be located in the same directory as the
source. The compiled units will be placed in the <project>/units
directory.
When you create you own project, all you need to do is tell Lazarus to
associate the 'fpgui_package.lpk' with your project and it will automatically
find all the fpGUI compiled units and source for you.
* Creating a new project. Select Project->New Project. Select
Program and click the Create button.
* Save the project in your preferred directory.
* Associate fpGUI with your project. Select Project->Project Inspector.
An new dialog will appear. Select Add then New Requirements. In the
Package Name combobox, select the 'fpgui_package' package and
click OK.
* You can now write your program and use any fpGUI units. Lazarus will
automatically include the paths to the fpGUI compiled units for you.
Building fpGUI from the Free Pascal Text IDE
============================================
First you would need to setup the 'fp' IDE to find the related files.
As far as I understand the text mode IDE has it's own built-in compiler
so doesn't read the standard fpc.cfg file.
* Run the text mode IDE from the command line: fp
* Navigate the menus to: Options|Directories and select the 'Units'
tab.
* Now enter the following directories replacing the relevant parts with
your actual paths. The example below is valid on my system only.
I was using FPC 2.2.0 under Linux and the X11 corelib backend.
/opt/fpc_2.2.0/lib/fpc/2.2.0/units/i386-linux/*
/opt/fpc_2.2.0/lib/fpc/2.2.0/units/i386-linux/rtl
/home/graemeg/programming/fpGUI/src/corelib
/home/graemeg/programming/fpGUI/src/corelib/x11
/home/graemeg/programming/fpGUI/src/gui
* Now select the 'Include files' tab and enter the following paths.
Again change the paths to point to your actual directories and
X11 or GDI corelib backend.
/home/graemeg/programming/fpGUI/src/corelib
/home/graemeg/programming/fpGUI/src/corelib/x11
* Now changes to 'Miscellaneous' tab, PPU output directory. Type in
the edit box: units
NOTE:
This will place all the compiled *.ppu and *.o files into a 'units'
directory inside you current directory. So make sure you create it
before you try to compile for the first time. FPC doesn't create
directories for you!
* Now you are ready to open your projects main program unit (F3) and
compiling it by pressing (F9).
Compiling any of the examples from the Command Line
===================================================
You need to compile fpGUI first as mentioned above!
Every project in the ../examples directory has it's own extrafpc.cfg file.
You only need to specify that config file and the project unit to compile
it.
fpc @extrafpc.cfg <project unit>
Example:
fpc @extrafpc.cfg docedit.lpr
MacOSX instructions and known issues
====================================
NOTE:
MacOSX is still an unsupported platform, but some users have reported
that it works, so I decided to add some of their notes here for any other
Mac users that want to try fpGUI.
To run fpGUI based application under MacOSX, you use the X11 backend. X11
is included with all recent MacOSX versions (in older OSX versions it was
a separate install - but included on the install DVD).
An example workflow to work with any fpgui app is:
a) launch X11 (Applications -> Utilities)
b) start the X11 console xterm (Cmd+N or from the X11 menu)
c) type the path to your fpgui application ( example: cd
./Documents/fpgui/examples/apps if you put fpgui in your Documents
folder)
d) type ./appname to start the application "appname"
* Apparently starting fpGUI apps from an icon on the desktop requires that you
double click the icon twice. This issue seems to be common with other X11
apps under OSX as well. eg: Gimp, any GTK2 app etc.. Alternatively, start it
from a X11 console, then it runs first time.
* This issue is more about FPC then fpGUI specific, but it's handy to know. In
many standard Xcode + X11 installation, the linker could not find the X11
libraries. So changing the fpc.cfg by adding
-Fl/usr/X11/lib
in the search library path solved the problem. Mac usually doesn't let you
choose the path during installation, so probably other Snow Leopard users
will have to double check the correct X11 library path.
* Compiling from the command line, the compiler cannot create the
sub-directory "units" used by most demos inluded with fpGUI. So remember to
create such a directory if the compiler fails. When using Lazarus IDE to
compile fpGUI projects, the IDE normally creates the missing unit output
path for you.
