Hi folks; this is just to let you know that I have resolved my problems I had with re-building the Pascal compiler and a persistent segementation fault on my Solaris 8 machine. Particluar thanks to Frank who kept making suggestions until I figured it out. It was, in fact, a loose pointer.

Re: Creating .so

Hello , We tried compiling a DLL with the following sources but have not been successful. program mycall; function add(x:integer;y:integer):integer; far; external 'mylib'; var b:integer; begin b:=add(5,6); end. -------------------------------------------- library mylib; uses winprocs; function add(x:integer;y:integer):integer;export; begin add:=x+y; end; exports add index 1; begin end. ------------------------------------------------- What changes do we have to make to the sources to build the DLL?

copying gpc built on one machine to another
by ANURADHA Srinivasan 27 Sep '01

27 Sep '01

Hello , Suppose i build GPC on one Sun-solaris 2.6 machine and i copy the built GPC to another sun-solaris 2.6 machine , it doesnot work.It says gpc-ccp not installed properly. But my case is like , i am in tools-support and we don't want to give our "internal customers" the elaborate task of building the compiler themselves and then porting the various sources. So, can you kindly tell me , how i can build the GPC in one machine and copy it to any other machine and use the GPC.It is just like the the already built sources that you have on the web.But, we have built it with the latest sources and also have added other units to the 'units' directory which we want everybodyelse to use. thanks and Regards, Anuradha -- S.Anuradha Generic Data Tools, Alcatel Chennai.

Rebuilding gpc (conflicting types)
by Hartmut Schmider 26 Sep '01

Hi, I need help again. I am re-building gpc on a solaris 8 workstation. All goes well, until the compilation halts with: In file included from /home/hasch/install/gcc-2.95.2/gcc/p/gpc-common.c:29: /home/hasch/install/gcc-2.95.2/gcc/p/gbe.h:152: conflicting types for `xmalloc' /home/hasch/install/gcc-2.95.2/gcc/p/../../include/libiberty.h:129: previous declaration of `xmalloc' In file included from /home/hasch/install/gcc-2.95.2/gcc/p/gpc-common.c:35: /home/hasch/install/gcc-2.95.2/gcc/p/util.h:196: conflicting types for `concat' /home/hasch/install/gcc-2.95.2/gcc/p/../../include/libiberty.h:48: previous declaration of `concat' What's the deal with 'libiberty'?

Random function
by Miklos Cserzo 26 Sep '01

26 Sep '01

Hi Folks, the memory leak problem not seems to be linked to the call of the "random" function. However, during the test I realized that the built-in "random" is piss poor. The test source goes at the end. You supposed to see evenly distributed numbers in the third column of the output. Try it for yourself. miklos ___________________________________________________ program cgr; { Chaos-game test of random number generator } const dim=100; { Change these if they are too large for you } cyc=100000000; var c,i,j,r:integer; s:array[-dim .. dim, -dim .. dim] of integer; x,y:real; begin for i:= -dim to dim do for j:= -dim to dim do s[i,j]:=0; x:=0; y:=0; for c:= 1 to cyc do begin r:= random(3); case r of 0:begin x:= (x+1)/2; y:= (y+1)/2; end; 1:begin x:= (x-1)/2; y:= (y+1)/2; end; 2:begin x:= (x-1)/2; y:= (y-1)/2; end; 3:begin x:= (x+1)/2; y:= (y-1)/2; end; end; i:= round( x*dim ); j:= round( y*dim ); inc(s[i,j]); end; for i:= -dim to dim do for j:= -dim to dim do writeln(i:6,j:6,s[i,j]:12); end.

Module Initialisation
by Loris Caren 25 Sep '01

25 Sep '01

-----BEGIN PGP SIGNED MESSAGE----- Can somebody explain what the init_module and fini_module fragments are for that I find in every dot-o emitted by GPC and explain how these fragments are called? I can see that something like this would be needed if/when a module has a 'body', but surely, if a module is just a collection of functions ,procedures and bss data (OK I admit my c background), no per-module initialisation or cleanup is required and these fragments shouldn't be necessary (or should just consist of an immeadiate return)? -----BEGIN PGP SIGNATURE----- Version: 2.6.3i Charset: noconv iQBVAwUBO688F5rsQW7OcFOlAQEGTgH/VW9Vmtgr8onyfewL0sF+3VZNJvepY3g6 mFXgvN7Hfm6PQ4b3mT6Ozjk4w27IFZCl4g37YenvziGUsl+dUhoVYQ== =cN27 -----END PGP SIGNATURE-----

Re: Using C library functions

Ive solved my own problem. It was the case sensitivity of the linker and an asmname directive sorted it out. Theo Carr-Brion -----Original Message----- From: Theo Carr-Brion [mailto:Theo.CarrBrion@mitrefinch.co.uk] Sent: 19 September 2001 16:27 To: 'gpc(a)gnu.de' Subject: Using C library functions I have some I/O routines for communicating over a serial line written using the C functions ioctl and write. We need to control time out times and the like. I have defined the functions as external but the linker can't find them. What do I need to do? Thanks in advance, Theo Carr-Brion

GPC, Linux and glibc
by Prof Abimbola Olowofoyeku 19 Sep '01

19 Sep '01

Hi all Does GPC link against glibc? I built GPC on a Redhat 7.1 machine and compiled a program there. The program won't run on a Redhat 6.2 machine. It dies with a message "/lib/libc.so.6: version 'GLIBC_2.2' not found ...". I thought that GPC only links 'libgcc.a'. What gives? And how can I force GPC to link only to static libraries? Thanks.
