dpr suffix

Hi All When I try to compile a program which source has suffix .dpr I get an eror message from linker: $ gpc -s --borland-pascal -DGPC -DSOLARIS --unit-path=../obj -o accom accom.dpr ld: elf error: file accom.dpr: unknown type, unable to process using elf(3E) libraries ld: fatal: File processing errors. No output written to accom collect2: ld returned 1 exit status Even if I exchange --borland-pascal for --object-pascal which seems to be Delphi compatibility mode, the story repeats. Is it GPC problem? Any ideas? ...besides changing filenames. I'm using GPC dated 19991030 build on GCC 2.95.2 on Solaris 8 x86. Thanks in advance for responses -- .

When I > test gpc, I get a long message starting with This looks like the compiler is working, and complains about some problems in the code begin compiled. Apparently, the code was written for another Pascal compiler (SGI Pascal???) which predefines some non-standard identifiers. I can give you a few tips how to define them in GPC. Some of the errors are probably consequences of the missing identifiers. > "tabutil.pas:25: warning: missing program header According to the standard, a program requires a `program' line at the beginning. If it's missing, GPC will warn, but still compile the program. > tabutil.pas:30: type name expected, identifier > `String80' given > tabutil.pas:31: type name expected, identifier > `String20' given > tabutil.pas: In function `Readint': > tabutil.pas:60: type name expected, identifier > `String255' given type String80 = String (80); String20 = String (20); String255 = String (255); > tabutil.pas:68: undeclared identifier `Depend_err' > (first use this function) I don't know what this is (haven't seen this anywhere before). Perhaps it's define in some module which is supposed to be compiled with the given source (via `imports' or as an include file, ...). Otherwise, you'd have to figure out what this procedure(?) is supposed to do... > tabutil.pas:69: undeclared identifier `Str2int' (first > use this function) > tabutil.pas:86: undeclared identifier `Str2real' > (first use this function) GPC supports: ReadStr ( <source string>, <integer, real, string, char>... ) and Val ( <source string>, <integer or real>, <result> ) (result will be 0 if successful, >0 if not) Based on this, you can write Str2Int and Str2Real as needed by your code. Since this depends on whether they are supposed to be procedures or functions and on their parameter lists, I can't give you drop-in routines, but perhaps something like the following: function Str2Int (const s: String) = Res: Integer; begin ReadStr (s, Res) end; (However, it looks like your code has a `ReadStr' routine itself, so either do the above before the (re-)declaration of `ReadStr' or use `Val'.) > tabutil.pas:102: undeclared identifier `Strg' (first > use this function) I don't know what this means. On German keyboards, `Strg' is the `Ctrl' key, but I doubt that's meant here. ;-) It could be Str(ing)G(reater) or anything else, but I really don't know without seeing some context (or documentation of the original compiler). > tabutil.pas:128: undeclared identifier `Fopen' (first > use this function) Looks like the name of a C funcion (fopen()). If that's really what's meant here, you can probably use the normal file routines (`Reset', `Rewrite', `Extend')... > tabutil.pas:136: undeclared identifier `Indx' (first > use this function) GPC supports `Index' (find a substring in a string), in case that's what `Indx' is supposed to be... If these things are really built-in declarations of some Pascal compiler (and not part of some other modules), we could try to add them to GPC. We have done this for other dialects or other compilers' definitions (in particular, Borland Pascal), so it wouldn't be completely new to us. However, we'd need some reasonable documentation on this compiler's declarations (or better yet, free code to implement them :-).

gpc missing program header
by Chris Karow 14 Apr '00

14 Apr '00

Hi, I am new to this mailing list but I have done a lot of upfront work before writing for help. I am new to compilers but have to install GPC compiler for a user. I have read the Install and Readme for gpc and gcc. I have also gone through all of 12/99 mailing list archive and I still need help. I am trying to use the compiler on an 32 bit SGI, v6.5 operating system. I downloaded the binaries for both the gcc (fw_gcc-2_8_1-sgipl2.tardist) and gpc (gpc-19990118.mips-sgi-irix6.2.tar.gz). I installed both, gcc in /usr/freeware and gpc in /usr/local. I've run gcc and tested it and it works fine. When I test gpc, I get a long message starting with "tabutil.pas:25: warning: missing program header tabutil.pas:30: type name expected, identifier `String80' given tabutil.pas:31: type name expected, identifier `String20' given tabutil.pas: In function `Readint': tabutil.pas:60: type name expected, identifier `String255' given tabutil.pas:63: only Pascal string type, array of char, and char type tabutil.pas:63: are assignment compatible with a string tabutil.pas:68: undeclared identifier `Depend_err' (first use this function) tabutil.pas:68: (Each undeclared identifier is reported only once tabutil.pas:68: for each function it appears in.) tabutil.pas:69: undeclared identifier `Str2int' (first use this function) tabutil.pas: In function `Readreal': tabutil.pas:76: type name expected, identifier `String255' given tabutil.pas:80: only Pascal string type, array of char, and char type tabutil.pas:80: are assignment compatible with a string tabutil.pas:85: undeclared identifier `Depend_err' (first use this function) tabutil.pas:86: undeclared identifier `Str2real' (first use this function) tabutil.pas: In function `Readstr': tabutil.pas:102: undeclared identifier `Strg' (first use this function) tabutil.pas: At top level: tabutil.pas:120: type name expected, identifier `String255' given tabutil.pas: In function `Readmatrix': tabutil.pas:126: type name expected, identifier `String255' given tabutil.pas:128: undeclared identifier `Fopen' (first use this function) tabutil.pas:131: argument to `length' must be of string or char type tabutil.pas:131: only Pascal string type, array of char, and char type tabutil.pas:131: are assignment compatible with a string tabutil.pas:132: subscripted object is not an array or string tabutil.pas:134: argument to `length' must be of string or char type tabutil.pas:134: only Pascal string type, array of char, and char type tabutil.pas:134: are assignment compatible with a string tabutil.pas:136: undeclared identifier `Indx' (first use this function) tabutil.pas:145: incompatible type for argument 2 of `Readstr' tabutil.pas:145: too many arguments to function `Readstr' tabutil.pas:146: incompatible type for argument 2 of `Readstr' tabutil.pas:146: too many arguments to function `Readstr' tabutil.pas:147: incompatible type for argument 2 of `Readstr' tabutil.pas:147: too many arguments to function `Readstr' tabutil.pas: In function `Scalematrix': tabutil.pas:195: subscripted object is not an array or string tabutil.pas:196: undeclared identifier `Indx' (first use this function) tabutil.pas: In function `program_noname': tabutil.pas:212: parse error before `End' When this didn't work, I unpacked the source in /usr/local/src for both gcc (gcc-2_8_1_tar.gz) and gpc (gpc-19990118.tar.gz. I moved the p dir. from gpc to gcc dir. and ran the patch and ran configure. I then ran make LANGUAGES=pascal and received errors like missing cfe so copied into /usr/lib/cfe. Also, received errors for the inttypes.h, staarg.h and cccp.c and corrected paths. Gave up on this and removed both gcc and gpc source dir. and reinstalled the gpc and gcc binaries. Tested gcc OK. Same error mess. for gpc. If I run gpc -v, the output is gpc vers.19990118, based on gcc 2.8.1. If I run gcc -v, the output is reading specs from /usr/freeware/lib/gcc-lib/mips-sgi-irix6.2/2.8.1/specs gcc version 2.8.1. I think I have compatible gpc and gcc vers. When I run gpc -verbose, I get "Using builtin specs. gpc version 19990118, based on gcc-2.8.1 ld -call_shared -no_unresolved -init __do_global_ctors -fini __do_global_dtors -_SYSTYPE_SVR4 -n32 /usr/lib32/mips3/crt1.o crtbegin.o -L/usr/local/lib/gcc-lib/mips-sgi-irix6.2/2.8.1 -L/usr/local/lib/gcc-lib/mips-sgi-irix6.2/2.8.1 -L/usr/local/lib -lgpc -lm -dont_warn_unused -lgcc -warn_unused -L/usr/lib32/mips3 -L/usr/lib32 -dont_warn_unused -lc -warn_unused -dont_warn_unused -lgcc -warn_unused crtend.o /usr/lib32/mips3/crtn.o ld32: FATAL 9: I/O error (crtbegin.o): No such file or directory" I had found this file under /usr/freeware/lib/gcc-lib/mips-sgi-irix6.2/2.8.1 and had worked with this path as well but to no avail.
