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
