Create a new directory for the source code. You have two ways to get the code:
svn checkout svn://svn.code.sf.net/p/skychart/code/trunk .
If you just want to compile the software without using the Lazarus interactive environment you can use the scripts available in the base directory.
Before running these scripts be sure to have the Free Pascal binaries in your PATH environment, this is where you find the fpcmake command.
In the base directory you also found the daily_build.sh script I use to automatically build the packages for Linux and Windows.
./configure [fpc=free_pascal_path] [lazarus=lazarus_path] [prefix=installation_path] make make install make install_data
For example to install the complete software from source on Ubuntu 11.10:
sudo apt-get install build-essential lazarus subversion svn co https://skychart.svn.sourceforge.net/svnroot/skychart/trunk skychart cd skychart ./configure fpc=/usr/lib/fpc/2.4.4 lazarus=/usr/lib/lazarus/0.9.30 prefix=/usr/local make sudo make install sudo make install_data sudo make install_cat1 sudo make install_cat2 sudo make install_pict
configure.cmd make make install make install_data
First, install the required components from src/skychart/component directory.
Click “Open Package”, select “component/cdccomponents.lpk”, click “Compile”, “Install”.
When the install tells you to rebuild Lazarus say Yes.
You can now open the main project files skychart/cdc.lpi and compile.
Lazarus show by default the last form added to the project. To view the main form use the menu Project / Forms, and select f_main.
To run in debug adjust Run-Run Parameters-Working Directory to your CDC directory.
To reduce the executable size for production, use strip and upx.
The library getdss and plan404 are written in C language. To compile them, install the gcc compiler (Mingw on Windows) and run make from each library folder.
A few Windows specific libraries and plugins are not yet ported to Lazarus, please use Delphi if you want to compile them.
To know which version of Lazarus is require for a specific version of Skychart, install the binary version and look at the menu Help / About. There is a line that show the FPC and Lazarus version used.
Install Lazarus from http://lazarus.freepascal.org. See http://wiki.lazarus.freepascal.org/Installing_Lazarus for more information.
Launch Lazarus and open the menu Package - Install/Uninstall Packages.
Check that Printer4Lazarus and TurboPowerIPro are installed, this is normally the case.
If not, install them from lazarus/component :
I use the following procedure to install or update Free Pascal and Lazarus on Linux with the cross compiler for Windows:
cd ~/fpc # svn co http://svn.freepascal.org/svn/fpc/branches/fixes_2_2 . svn up make clean make build sudo make install make clean OS_TARGET=win32 CPU_TARGET=i386 make build OS_TARGET=win32 CPU_TARGET=i386 sudo make crossinstall OS_TARGET=win32 CPU_TARGET=i386 ver=`fpc -iV` sudo ln -f -s /usr/local/lib/fpc/$ver/ppc386 /usr/local/bin sudo ln -f -s /usr/local/lib/fpc/$ver/ppcross386 /usr/local/bin cd ~/lazarus # svn co http://svn.freepascal.org/svn/lazarus/trunk . svn up make clean make OS_TARGET=win32 CPU_TARGET=i386 clean make bigide make OS_TARGET=win32 CPU_TARGET=i386 bigide
The following naming convention is used for the main project source code to enable quick recognition of the destination of the units.
cdc.lpi : The main project pu_*.pas : Form units with specific code only pu_*.lfm : Form definition cu_*.pas : Unit containing non-visual object. u_*.pas : Unit with generic code.
