You can now hack the code (I recommend using Eclipse CDT) and have your own prodatum flavor. if you have problems anywhere in the process don't hesitate to bother me. ;-) Janus
[1] If you are on Windows get minGW: use the Graphical User Interface Installer as described here. Make sure to check the C++ compiler and developer tools options when you install! Once installed you have all the tools you need to build prodatum!
[2] minGW: Start an Msys shell from the start menu. Locate the extracted FLTK sources and change to the directory above (eg if you extracted FLTK to /c/fltk-1.1.10, go to /c).
Download the "gleam" patch and patch FLTK as described on the gleam homepage. Make sure to get the patch for FLTK 1.1.10!
Copy fl_gleam.cxx from the prodatum sources to /c/fltk-1.1.10/src/.
Now change into the fltk-1.1.10/ directoy and type: ./configure --disable-threads --disable-gl --disable-cygwin && make [ENTER]. This will build FLTK.
[3] This is tricky for Windows! I recommend getting Eclipse CDT and using these project settings (archive includes ready to use static windows lib and project setting to build it).
[4] fluid is the interface designer of FLTK and can be found in /c/fltk-1.1.10/fluid/ (once you have compiled FLTK)
