When I compile this code:

program radar;

...

uses     crt, graph;

var     DriverVar, ModeVar : integer;

begin         DriverVar := Detect;         ModeVar := 2;         InitGraph(DriverVar, ModeVar,'');         SetColor(4);         LineTo(100,100); end.

I get an error message:

mao@mao-note-arch Pascal $ fpc radar.pas

...

Free Pascal Compiler version 2.6.0 [2012/01/02] for x86_64 Copyright (c) 1993-2011 by Florian Klaempfl and others Target OS: Linux for x86-64 Compiling radar.pas Fatal: Can't find unit graph used by radar Fatal: Compilation aborted Error: /usr/bin/ppcx64 returned an error exitcode (normal if you did not specify a source file to be compiled)

Why is this happening?

1) Is 'Detect' integer? I can't tell from here. 2) Shouldn't InitGraph receive a path? See "PathToDriver" in http://www.freepascal.org/docs-html/rtl/graph/initgraph.html

Hello. Did you read the error message yet? It says, there's no unit graph. there is, however a package called graph, which is not associated with what you wnat from the compiler. However, I looked into things: martti@deepthought:~$ pacman -Ql fpc | grep graph fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/Package.fpc fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ggigraph.o fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ggigraph.ppu fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/libpggigraph.a fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/libpptccrt.a fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/libpptcgraph.a fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ptccrt.o fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ptccrt.ppu fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ptcgraph.o fpc /usr/lib/fpc/2.6.0/units/x86_64-linux/graph/ptcgraph.ppu After a minimum of testing I found that pascal units are stored as ".ppu" files. Then I tried this: "uses ptccrt, ptcgraph" - and it compiled. My pascal knowledge is very limited, and the first program pops away just after it is started... maybe you could wait for X keyboard events or add an endless loop. cheers! mar77i

Because graph does not exist in x86_64. Anyway if you want to use graph in i686 you need svgalib (from AUR), and who knows if works in these days... -- Gerardo Exequiel Pozzi \cos^2\alpha + \sin^2\alpha = 1
