"set_words_big_endian"
by Sven Jauring 17 Dec '01

17 Dec '01

Hi all A couple of months ago, I someone could tell me whether it was possible to have record variants of sets lesser than 32 members to be aligned. Frank Heckenbach told me to make GPC use 8 bits as the smallest size for a set, by changing TSelElement in p/rts/sets.pas and set_word_size and set_alignment in p/util.c. That worked great, had it not been for the fact that the code depended on reversed ordering of those bytes! (Actually, what I need is the elements in the set to represent the binary bits in a consecutive order) In the following code, I need BIT0 to be represented by the most significant bit of USRINT, and BIT15 by the least significant. *********************************** TYPE INT16 = INTEGER(16); INT8 = packed -128..127; INT0_65535 = packed 0..65535; B_TYPE = (B1, B2, B3, B4, B5, B6, B7, B8); BITS = (BIT0, BIT1, BIT2, BIT3, BIT4, BIT5, BIT6, BIT7, BIT8, BIT9, BIT10, BIT11, BIT12, BIT13, BIT14, BIT15); B_TYPE_SET = set of B_TYPE; BIT_SET = set of BITS; VAR OUT_REC = record case INT16 of 0 : (BSLB : B_TYPE_SET; BSHB : B_TYPE_SET); 1 : (USRINT : INT0_65535); 2 : (BT : BIT_SET); end; ************************************ I tried to change set_words_big_endian to "1", in p/util.c! That made the bit representation work, but when I tried running p/test/setest.pas, I got the following result: "The set opcodes work : [] False mul plus minus in and rel False" Is there a way to get sets to use "set_words_big_endian", or am I on a totally hopeless mission, all together? It would really save my day if this would be possible! Best Regards and Merry Christmas Sven Jauring

bug report
by Russell Whitaker 15 Dec '01

15 Dec '01

hi Some time age wrote a program using an array of pointers to fixed capacity strings. The plan is to rewrite the program to use variable capacity strings. So while playing to see what *might* work got this: ../../../gcc-2.95.3/gcc/p/types.c:1107: failed assertion `capacity && TREE_CODE (capacity) == INTEGER_CST' buff.pas:25: Internal compiler error in `declared_string_capacity', at types.c:1107 Please submit a full bug report to the GPC mailing list <gpc(a)gnu.de>. See <URL:http://home.pages.de/~GNU-Pascal/todo.html> for details. from this: unit Buff; interface const MAXLINES = 20000; type lline = string ( 4000 ); {buffer for data xfer} procedure BB_AppendLine( Aline: lline ); {adds to end} implementation var cap : integer; type ptrline = ^Line; Line = string ( cap ); TbbArray = array[1..MAXLINES] of ptrline; var BigBuffer : Tbbarray; {array of pointers to data} LineCount : integer = 0; FileUpdate : boolean = false; LineItem : Line; procedure BB_AddLine( Aline: lline ); begin cap := lline.length; BigBuffer[ LineCount ] := new( ptrline, LineItem ); BigBuffer[ LineCount ]^ := Aline; inc( LineCount ); end; j.i.c., installed that latest patch - same results. Incidently, this won't work, either: type cap = integer; Aline = string( cap ); {gives err msg} Thanks, Russ

What should Trim do?
by Martin Liddle 13 Dec '01

13 Dec '01

What should the trim function do? It seems to me that under gpc it removes trailing spaces from a string. Under Delphi it removes leading and trailing spaces. Unfortunately I don't have any Turbo Pascal documentation to hand (I assume trim is a Borlandism). -- Martin Liddle, Tynemouth Computer Services, 27 Garforth Close, Cramlington, Northumberland, England, NE23 6EW.

Units o libraries to create 2D graphics
by pascal＠gargal.com 13 Dec '01

13 Dec '01

Hello, I just installed gpc in a HP-UX 11.00. I programmed in Pascal a long time ago. I'd like to know if you know which unit or library I can use to create jpg files with 2D graphics like number of users vs. memory usage to make them viewable in a Web page? Thanks for your help! Hermenegildo

I note the "i586" in that name. I am running on a 486.

Well AFAIK, there is no "later than 2.95.3", that is suitable. From previous discussions, 3.XX is not currently supported by GPC and 2.96 is a broken version of GCC, so 2.95.3 is "it" (since this version for DJGPP is not listed below, by implication there were no problems with it, so I expect Maurice will have a build available shortly:-). BTW, I did notice at "http://www.distrowatch.com/debian.htm", that there exists also a GCC 2.95.4, but I have not heard anything about this version ... Joe. PS.

Will GPC ever be an integrated part of GCC?

This question has probably been asked before, but anyway... Will GPC ever be an integrated part of GCC? Wouldn't this automatically increase it's use?

Re: Units o libraries to create 2D graphics
by da Silva, Joe 13 Dec '01

13 Dec '01

As I recall, there is a Pascal translation of the Independent JPEG Group's graphics library, available at Simtel.Net (haven't tried it, so I don't know if it's any good, nor if it does what you want). There are also some graphics libraries for Pascal listed at "http://www.thefreecountry.com/developercity/graphicslibraries.shtml" that support the JPEG format, some may include source. Again, haven't tried any, so the same comments apply. Of course, the JPEG format is fairly sophisticated (ie. complicated), with variable compression ratio (depending on image quality), so for a small number of images (ie. small storage requirements), it might be simpler to use another format, such as GIF or PCX? Beware that GIF compression uses the LZW algorithm and is patented, although it's use is optional (BTW, AFAIK, the LZW patent should expire in mid-2003). Joe. PS. Hmmm ...
