Build Problems
by Frank D. Engel, Jr. 11 Aug '02

11 Aug '02

I am trying to build GPC under IRIX. I followed the basic set of instructions from the GPC manual, or wherever it was that I found them, with the exception that I am building all of the compilers instead of just GPC (originally I tried using the specified option to only build GPC, then left it off afterward, and the result is the same). GCC Version: 2.95.3 GPC Version: 20020510 IRIX Version: 6.5.15m Using GNU make (called with the command 'gmake' under IRIX). The problem is this: The build gets to a certain point, then gives me an "internal error" in the compiler. I tried placing empty Pascal files in place of some of the originals, but the error simply changes to occur in a different source file (the original files are now restored). The error is as follows: ../.././xgpc -B../.././ -c <...> <home>/gcc-2.95.3/gcc/p/rts/string.pas <home>/gcc-2.95.3/gcc/p/rts/string.pas: In procedure 'Upcasestring': <home><.....>/string.pas: 177: Internal compiler error in 'modified_type_die', at gcc-2.95.3/gcc/dwarf2out.c:6485 Can someone please help me with this? I really want to get this working, but have not been able to get around this bug. If any further info is needed, let me know. Also, I have some experience programming in a variety of languages, etc., so if you need me to make changes/etc. and try things, I am open to suggestions -- I can at least try. I am familiar with C, thouroughly enjoy Pascal, and am somewhat knowledgeable about UNIX (I have worked with Linux, Solaris, IRIX), so I can handle the OS for the most part as well. Thank you for any help you can provide! Also: I did not see another means of bug reporting, if there is one, let me know so that I can resubmit this in the appropriate way. Thank you. ===== ======= Frank D. Engel, Jr. Please note my new address: fde101(a)yahoo.com __________________________________________________ Do You Yahoo!?

ANN: ZLib Unit
by Eike Lange 08 Aug '02

08 Aug '02

Welcome to the wonderful world of Zlib zlib 1.1.4 is a general purpose data compression library. All the code is thread safe. The data format used by the zlib library is described by RFCs (Request for Comments) 1950 to 1952 in the files http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format) and rfc1952.txt (gzip format). These documents are also available in other formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html This unit is based on zlib 1.1.4 Differences to zlib.h: ====================== - No underscores - ZLIB_VERSION is renamed to ZLibVersionConst - function ZlibVersion returns String - function GzEof returns boolean value - GzError returns String - SEEK_SET and SEEK_CUR are introduced in this unit as SeekSet and SeekCur. These consts are needed as the "whence" parameter to GzSeek It would be wonderful, if someone could review this unit. Download from: http://gnu-pascal.de/contrib/eike/ Eike

Re: Some strange behaviour of GPC
by da Silva, Joe 07 Aug '02

07 Aug '02

Not sure why you are doing things this way, anyhow ... Why not eliminate the non-standard "BitSize" function?, thus : program tst; const BitArraySize = 19; var aa : packed array [1..BitArraySize] of boolean; begin ...... Also, why are you using a pointer to your array, why not simply pass it to your "Find_First_bit_Set" function as a parameter (var parameter, if you wish)?

General GNU Pascal questions
by Heine Ferreira 06 Aug '02

06 Aug '02

Hi I am new to GNU Pascal so please forgive my basic questions. Does the compiler under Windows work in a text mode or GUI mode? Can you write GUI programs with this? Does it support ODBC or OLE DB or any particular database? Does the compiler have an IDE? Can it use DLL's or ActiveX controls? I don't understand how to download and install the Windows version. Can you help me please? Must you first install the DOS version? Thank you Heine Ferreira

sizeof/high/getstringcapacity
by Preben Mikael Bohn 02 Aug '02

Hi all. Will sizeof(somestring) always be 9 bytes larger than high(somestring)/getstringcapacity(somestring)? Or is it just in one case I have found this...

Hi! Welcome to the wonderful world of XLib Unit. This unit interfaces Xlib.h and X.h. Xlib is a very basic library you may need for creating graphical user interfaces (GUI). If you need some documentation about XLib-Programming, please visit the following sites: (I am not responsible for the contents of these sites) * http://www.tronche.com/gui/x/xlib/introduction/ * http://www.rahul.net/kenton/xsites.framed.html It would be wonderful, if someone could review this unit.

operators
by Kresimir Veselic 25 Jul '02

25 Jul '02

Dear gpc-ers, here is a question by an unskilled programmer: Upon the program program driver0; {$I complexop.p} var a,b,c,d: scomplex; begin a.re := 1; a.im := -0.1; b := a; c := b * b; c := a + c; d := c + b * b; writeln(c.re,' ',c.im); end. the gpc compiler reacts: driver0.p: In main program: driver0.p:10: reference expected, value given However if the incriminated line 10 (d := c + b * b) is commented out the program compiles and executes ok. The include file contains overloaded operations + and * for complex numbers as records. Can you tell what is wrong without looking into the (rather long) include file. Thanks in advance, K. Veselic.

Problems installing GPC
by Preben Mikael Bohn 24 Jul '02

24 Jul '02

Hi all, I have a problem installing both the gcc and the gpc compiler. I use the following (taken directly from http://www.gnu-pascal.de/gpc_51.html#SEC51 ): tar xzf gpc-20020510.tar.gz tar xzf gcc-core-2.95.2.tar.gz cd gpc-20020510 mv p /export/athen01/prb/programs/gcc-2.95.2/gcc/ cd .. mkdir gpcbuild cd gpcbuild /export/athen01/pmb/gpc/gcc-2.95.2/configure --prefix=/export/athen01/pmb/gpc make make -n install make install At the last step I get the following error: chmod a-x "/export/athen01/pmb/gpc/doc/gpc/BUGS" "/export/athen01/pmb/gpc/doc/gpc/demos"/* if [ "`cd p/docdemos && echo a*`" != "a*" ]; then \ (cd "/export/athen01/pmb/gpc/doc/gpc/docdemos"; for f in *; do rm -f "$f"; done) && \ for f in `cd p/docdemos && echo *`; do \ rm -f "/export/athen01/pmb/gpc/doc/gpc/docdemos/$f"; \ /bin/sh /export/athen01/pmb/gpc/gcc-2.95.2/install-sh -c -m 644 "p/docdemos/$f" "/export/athen01/pmb/gpc/doc/gpc/docdemos/$f" && \ chmod a-x "/export/athen01/pmb/gpc/doc/gpc/docdemos/$f" || exit 1; \ done; \ fi install: p/docdemos//export/athen01/pmb/gpc/gpcbuild/gcc/p/docdemos does not exist make[1]: *** [pascal.real-install-doc] Error 1 make[1]: Leaving directory `/export/athen01/pmb/gpc/gpcbuild/gcc' make: *** [install-gcc] Error 2 And gcc is not build. The strange thing is that it works flawlessly on another RedHat 7.3 system... On the RH7.3 I use gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-110). On the "failure"-system I'm using gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-98) Any ideas what is wrong???

Latest sources...

Where can I find the latest sources? I checked on the web site but was confused and downloaded the wrong thing. Also, does GPC still require Linux in order to be compiled properly? See ya! Orlando

Have you tried the "--autobuild" command line option?
