faq addition (was Re:help!)
by Russ Whitaker 16 May '00

Hi >... may be something about this should be added to FAQ ? Good idea. Perhaps the following: Why shouldn't I just grab and install a binary? ================================= Linux may be Linux, but many details are left up to the implementor. If that isn't enough updating a seemingly unrelated piece of software can cause compatibility problems. Witness this exchange from the mailing list: >>I'm not an expert on this, but I remember that I installed on my Linux >>(RedHat 6.1) two RPM packages: >> >> gpc-19990118-1.i386.rpm >> gpc-extras-19990118-1.i386.rpm > I have install all but it doesn't run anyway! > My Linux is mandrake 7.0, it is maybe the problem?... Mandrake is NOT compatible with RedHat despite claims - you need less manual tweaks then in case with SuSE or Debian but ONLY RedHat is compatible with RedHat (even in this case only if you are lucky enough - see below). ESPECIALLY for GPC: Mandrake traditionally using very "advanced" (read: barely working) versions of gcc and gpc relies HEAVILY on gcc. If you DO NOT have RPM for EXACTLY your distribution then better (=easier) to recompile GPC from sources. And when I'm saying EXACTLY I mean exactly: RPM for RedHat 5.0 WILL NOT work in RedHat 5.2, RPM for RedHat 6.0 WILL NOT work in RedHat 6.2, etc. In some cases even "RedHat x.y" can be incompatible with "RedHat x.y with updates" :-(( Usually it can be easily tracked down and fixed by knowledgeable person (almost any package for any distribution can be forced to work in almost any other distribution) but just "rpm -Uvh" quite often will not work. When you are compiling program from sources autoconf usually can find and compensate most differences automagically but rpm/dpkg/apt is NOT sophisticated enough. That's why we recommend to start from sources when binaries do not work for you. Russ <russwhit(a)mind.net>

Do you have a working C compiler? try cc -v and you should get version info. The version is not important, the response is, as cc is used for the first of the three passes to build GPC. 2. Did you install a package of "include" files? These are a bunch of files ending in .h and found in a directory or sub directory called include. In the Slackware distribution the package is called linuxinc.tgz and they consider it important enough to provide two copies - one in the D series and the other in the K series. In a simplistic sense these files tell the C compiler how to use the library. Now try make, again Russ <russwhit(a)mind.net>

Hello! My name is Janet Casey and I'm working for the Free Software Foundation assembling a database of free software world wide, which is why I'm writing to you. We have this address listed as the maintainer for 'gpc'. Can you take a quick look through the information I've assembled to see if everything is correct and if there's anything I should add? I'd appreciate it greatly. FYI- a short explanation of some of the fields. Programs- any additional programs that come included with this one. Interface- Command line, interactive, X windows, console Support- listed only if it's something other than mailing list support Repository- Any CVS repositories where the program is listed Related- any GNU packages that might be of interest to users of this package Use Requirements- Required for using the executable Build Prereq.- Required for building this package Weak Prereq.- Useful (but not mandatory) to install before building this one Source Prereq.- Packages whose source code must be present in order to build this package. Please bear in mind that not all packages will have all the fields filled in (in fact, I don't think we've run across any yet that have all the fields filled in). If there's anything you think should be added (particularly individuals who have contributed) please e-mail me.

help!
by Nathalie Jarosz 15 May '00

15 May '00

Hi Is someone can help me?!!! I really need to use a pascal compiler and I can't run it correctly. I manage to install a pascal compiler with "gpc-19990118-2rh6_i386(1).rpm... But, at first, when I did the command: $gpc -o test test.p, it says ld : cannot open crt1.o : no file or directory of this type. So, I tried to locate this file, and the only solution I find to go on was to copy it where I want to compile. It was the same for 'begincrt.o' and 'crti.o'. After this, the message was : ld : cannot find -lm. So, I create a variable called LFLAGS to export the libraries: $ export LFLAGs="-L /usr/i586-glibc20-linux/lib" and with the line: $ gpc -o test $LFLAGS test.p 'test' is created but when I run it, the following message appear: 'segmentation fault' What does it mean? thanks a lot in advance for your help, I guess some people use this so explain how you do to run it correctly, it's really important for me.

Is there a way to do this with GPC? No. For Booleans, it would not be too difficult to implement, but for enum types, it would require that they're values (which are program identifiers otherwise) be kept in the executable which is not provided for currently (besides debug info). > If not, are there > any good ways to emulate this behaviour? Something like the following. It also illustrates the limitations... program ReadBooleanEnumDemo; uses GPC; procedure ReadWord (var f : Text; var s : String); const WordChars = ['A' .. 'Z', 'a' .. 'z', '_', '0' .. '9']; begin s := ''; while f^ in SpaceCharacters do if EOLn (f) then Readln (f) else Get (f); while not EOF (f) and not EOLn (f) and (f^ in WordChars) do begin s := s + f^; Get (f) end end; function ReadBoolean (var f : Text) : Boolean; var s : TString; begin ReadWord (f, s); LoCaseString (s); if s = 'false' then ReadBoolean := False else if s = 'true' then ReadBoolean := True else begin IOErrorCString (464, FileName (f)); { error when reading from % } ReadBoolean := False end end; function ReadEnum (var f : Text; const IDs : array of PString) : Integer; var s : TString; i : Integer; begin ReadWord (f, s); LoCaseString (s); i := Low (IDs); while (i <= High (IDs)) and (LoCaseStr (IDs [i]^) <> s) do Inc (i); if i <= High (IDs) then ReadEnum := i else begin IOErrorCString (464, FileName (f)); { error when reading from % } ReadEnum := 0 end end; procedure WriteEnum (var f : Text; EnumVal : Integer; const IDs : array [m .. n : Integer] of PString); begin Write (f, IDs [EnumVal]^) end; type TFruit = (Apple, Orange, Banana); const FruitIDs : array [TFruit] of PString = (@'Apple', @'Orange', @'Banana'); var BoolVar : Boolean; FruitVar : TFruit; begin Write ('Enter a boolean and a fruit: '); BoolVar := ReadBoolean (Input); FruitVar := TFruit (ReadEnum (Input, FruitIDs)); { we have to cast the result to the enum type } Writeln ('You entered:'); Writeln (BoolVar); WriteEnum (Output, Ord (FruitVar), FruitIDs) end.

- Initialising enumerated types
by Wren Lee 05 May '00

05 May '00

DEC-Pascal has the ability to initialise a boolean or an enumerated type from a text file.The text is case insensitive and is read just as any other variable. Is there a way to do this with GPC? If not, are there any good ways to emulate this behaviour? I am currently using GPC v.19991030 based on 2.95.2 19991024 on a LINUX PC. The following program shows the functionallity that I am trying to emulate. Thanks in advance, Lee. --- PROGRAM Read_Enum(input, output); TYPE colour = (red, green, blue); VAR flag : boolean; { Test boolean } mycol : colour; { Test enumerated type } ip_file : TEXT; { input data file } filename : String(80); i : integer; BEGIN filename := "enum.dat"; open(ip_file, filename, history:=old); reset(ip_file); FOR i := 1 to 3 DO BEGIN readln(ip_file, flag); IF (flag) then writeln("Flag is true") ELSE writeln('Flag is false'); END; FOR i := 1 to 3 DO BEGIN readln(ip_file, mycol); CASE mycol OF red : writeln("Your colour is red"); green : writeln("Your colour is green"); blue : writeln("Your colour is blue"); END; END; close(ip_file); END. enum.dat: ======== true False TrUE Red green BLUE output: ====== Flag is true Flag is false Flag is true Your colour is red Your colour is green Your colour is blue -- The Information contained in this E-Mail and any subsequent correspondence is private and is intended solely for the intended recipient(s).
