Two steps are required - sorry, I forgot to mention that in my previous 
post (though I did to the person i created this zip for originally).

1) I find it always useful to have the <fpc>\bin\ directory in my PATH 
so that the fpc.exe executable can be run from anywhere.

2) You need to adjust the fpc.cfg file (located in the 'bin' directory) 
to match your install path. My path was:

    c:\lazarus\fpc\3.0.2\x86_64-win64

Back in FPC 2.4.x I installed Lazarus which included FPC, which in turn 
installed the FPC under the c:\lazarus\fpc\ directory. Ever since every 
FPC update, I just stuck to that install location. So you don't need to 
have it like this obviously.

The FPC Text IDE (64-bit) runs just fine here under Windows 7 64-bit. 
See attached screenshot. Even mouse support works inside the Text IDE.

I mostly use MSEide for all my console, web and fpGUI related 
programming. I created some custom project templates and away I go. 
Lazarus has some nice editor features, but is often buggy and the 
Lazarus Package system just doesn't work for me. With MSEide I use 
global (or per project) path macros instead. This gives much more 
reliable compilations.

Here is the command line equivalent of what my MSEide project does for 
the ptcgraph + aggpas demo.

C:\lazarus\fpc\3.0.2\x86_64-win64\bin\fpc.exe 
-oaggpas_ptcgraph_output.exe -Fuc:\devel\fpgui\src\reportengine 
-Fuc:\devel\fpgui\src\corelib\render\software 
-Fic:\devel\fpgui\src\corelib\render\software -Fic:\devel\fpgui\src 
-Fuc:\devel\fpgui\src\corelib\gdi -Fic:\devel\fpgui\src\corelib\gdi 
-Fuc:\devel\fpgui\src\gui -Fuc:\devel\fpgui\src\corelib -l -Mobjfpc -Sh 
-Sc -Si -gl -O- -FUunits -viewnh aggpas_ptcgraph_output.pas


As for AggPas. I use the version of AggPas that is included with fpGUI. 
I simply make sure the path to AggPas is specified in the project 
compiler settings, which in the above command line parameter is:

    c:\devel\fpgui\src\corelib\render\software

FPC then compiles all units as it needs them, and I always output the 
compiled units into a project specific "units" directory (the -FUunits 
command line parameter seen above). I don't like mixing *.pas and 
*.o;*.ppu files in the same directories.

I assume you mean the executable of the ptcgraph+aggpas demo? I'll do so 
in a private email.
