I would like to use the pencil library in my own project. Unfortunately I do not know how to comile it as I do not have experience with C programming (I know a few things but never compiled anything major by myself). I saw that there is a makefile included but this seems to be for GCC SDK on unix like systems. But I hope that I can compile it using gcc on RISC OS What I did: - Download the source code of the library - Installed gcc and tested it with the "hello world" example - it compiled - I made a new directory, set it as work directory - added "c" and "h" directories, copied the files into it and removed the /c and /h ending - trying to compile with: "gcc pencil_build.c -o penciltest" - got error messages about missing files, solved that by: - adding the oslib directory from !NSTools - adding missing "types" file from downloaded OSLib archive - changed os file: "oslib/types.h" --> "types.h" - changed os file: "oslib/oscore32.h" --> "oscore.h" I think that it is not a good idea to changes the files of the library but from the error messages I got gcc was unable to find the files. After changing them the files were found. But now I am stuck with it at the following point: *gcc pencil_build.c -o penciltest pencil_build.c: In function `pencil_free_item': pencil_build.c:214: error: 'for' loop initial declaration used outside C99 mode pencil_build.c: In function `pencil_dump_item': pencil_build.c:234: error: 'for' loop initial declaration used outside C99 mode pencil_build.c:250: error: 'for' loop initial declaration used outside C99 mode pencil_build.c:269: error: 'for' loop initial declaration used outside C99 mode Would be very nice if somebody could help me. If this is only the tip of the iceberg of problems and somebody has a compiled version of the library this is also fine for me. Thank you very much, Michael Gerbracht
