The simplest way is to add a ./src directory to your existing cdc binary directory.
Download the source file skychart_v3_xxx_source.tar.gz to this directory and extract the file here.
On Linux the command is : tar xzf skychart_v3_xxx_source.tar.gz
Or better get source from Subversion using a svn client.
The command is:
svn co https://skychart.svn.sourceforge.net/svnroot/skychart/trunk .
Finally you must have something like that :
cdc -| < base directory containing the executable |- src -| < devel directory |- skychart | < skychart module |- component < project component |- library < project library |- ... |- units < all compilation object go here |- tools | - data < the "data" directory structure require to run the progran | - ... < various tools not necessarily useful to the end user
To use this source code install Lazarus using the last daily snapshot or SVN version from http://lazarus.freepascal.org. See http://wiki.lazarus.freepascal.org/Installing_Lazarus for more information.
Launch Lazarus and open Components-Configure, Installed Packages.
Check that Printer4Lazarus, JPEGForLazarus and TurboPowerIPro are installed, this is normally the case with the version 0.9.18. If not, install them from lazarus/component
printers/printer4lazarus.lpk jpeg/jpegforlazarus.lpk turbopower_ipro/turbopoweripro.lpk
Then from src/skychart/component directory install the package for the required component:
Click “Open Package”, select “component/cdccomponents.lpk”, click “Compile”, “Install”.
When the install tell you to rebuild Lazarus say Yes.
You can now open the main project files skychart/cdc.lpi and compile.
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 library and plugin are not yet ported to Lazarus, please use Delphi if you want to compile them.
The following naming convention is use for the main project source code to allow to quickly recognise the destination of a unit.
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.
