auto dependency generation
by Bryan Meredith 14 Jan '04

14 Jan '04

Is there an equivalent to the gcc -MM command? For those that haven't come across it, it produces a dependency list for the given file that you can then use in make. I am aware of the --autobuild option but the source that I have inherited needs dependencies in the makefile itself due to having to calculate targets on the fly depending upon what data is supplied, There is no way around it :/ I can force a complete rebuild each time (which isnt too time consuming really) but I would rather know that stuff gets built when it is needed, just in case... Thanks in advance, Bryan "Brain Murders" Meredith

GPC on ARM7tdmi problems: libos-hack, ncurses
by Igor Marnat 13 Jan '04

13 Jan '04

Hi dear All. I'm trying to build some pascal program for ARM7TDMI using GPC as a cross compiler for ARM (host - i686, RedHat9; target - uclinux, ARM7TDMI, gcc - 2.95.3, gpc - 20010315). I've got some problems, could you please help me with those: 1. When I include unit CRT in my program, GPC asks for libos-hack library that I don't have on my machine. After some investigation I found that I can change file rts-config.inc (i.e. write there string #UNDEF HAVE_LIBOS_HACKS) to avoid this issue. Is it any bug in GPC configuration script? Is it just enough to change this string for system to work correctly? I didn't manage to find any notes about libos-hack in Google. 2. After I have removed this issue about libos-hack, arm-elf-gpc asked for libpanel library from ncurses but cannot find it. How should I correct this problem? I read configuration scripts for ncurses and found that they use only usual gcc, there is nothing like $(target)-gcc in the scripts. Is it possible to build and install ncurses for ARM? I think I cannot use library /usr/lib/libpanel.a for ARM if it is compiled using usual gcc for Intel. Is it possible to install ncurses so that only source files will be used (i.e. without libraries)? Or is it possible to build ncurses for arm using arm-elf-gcc? Thanks a lot, Igor Marnat. mailto:marny@rambler.ru

Problem with gpc-20030830 unter MinGW

11 Jan '04

Hi folks, I'm trying to build the gpc-20030830 alpha version on my MinGW system. In my current attempt I'm directly compiling from within the gcc-3.2.1 core directory. I start building with the command ./configure --prefix=C:/MinGW --enable-languages=pascal Then `make' always aborts with the following message: make[2]: Entering directory `/mysoftware/gcc-3.2.1/gcc/p/rts' make[2]: Nothing to be done for `generated-files'. make[2]: Leaving directory `/mysoftware/gcc-3.2.1/gcc/p/rts' cd ./p/rts && make -f Makefile.in srcdir=.

Thanks for your timely help!!

Sir, Thank you very much for your mail about patching GCC. I downloaded Patch from http://www.gnu.org/directory/patch.html site. (patch-2.5.4.tar.gz). I unpacked the same in my GNU work folder (gnu/gcc-3.2.2/gcc). But when I tried configuring GCC, it gives same message (You can try to patch GCC manually by typing a command like *** `patch -p1 < p/diffs/gcc-2.95.diff' and patching possible rejects *** by hand before you run `./configure' again.) When I tried patch command it didnt work for me. How to install Patch command..? In the README file aslo nothing is given about patch. Is it necessary to install patch? If so what I have to do? The following error occurs: [root@EXE-INDIA2 gcc]# patch -p1 < p/diffs/gcc-2.95.diff bash: patch: command not found But when I try the same configure command under /gnu/gcc-3.2.2/gcc/patch-2.5.4, then it worked.Few lines of output as follows: [root@EXE-INDIA2 patch-2.5.4]# configure --enable-languages=pascal loading cache ./config.cache checking host system type... i686-pc-linux-gnu checking for gcc... (cached) gcc checking whether the C compiler (gcc ) works... yes checking whether the C compiler (gcc ) is a cross-compiler... no checking whether we are using GNU C... (cached) yes checking whether gcc accepts -g... (cached) yes [root@EXE-INDIA2 patch-2.5.4]# make install /bin/sh ./mkinstalldirs /usr/local/bin /usr/local/man/man1 /usr/bin/install -c patch /usr/local/bin/`echo patch | sed 's,x,x,'` /usr/bin/install -c -m 644 ./patch.man /usr/local/man/man1/`echo patch | sed 's,x,x,'`.1 Is this correct? To my knowledge the above commands should work in the gnu work folder.. Sorry for disturbing you again ana again. Thanks and regards, B.Gayathri

Status of pthread support
by Bryan Meredith 08 Jan '04

08 Jan '04

I notice in the Planned Features - Misc page the comment: multithreading support ?? ??? Am I to take it that there are problems with thread support in gpc or is this an old comment? For my task, I would need support under Linux on intel/amd. Thanks in advance, Bryan "Brain Murders" Meredith

Help!!

Sir, I downloaded the GNU latest version gpc-20030830 and followed the installation instructions given in your web site. But when I configure the GCC, it asks to do patching, as follows: *** ./configure detected GCC version 3.2.2. *** GPC 2.1 requires one of the following versions of GCC sources to build: *** *** 2.8.1 *** 2.95.1 *** 2.95.2 *** 2.95.3-5 *** 2.95.3-6 *** 2.95.3 *** 2.95.4 *** 2.95 *** *** (You can try to patch GCC manually by typing a command like *** `patch -p1 < p/diffs/gcc-2.95.diff' and patching possible rejects *** by hand before you run `./configure' again.) When I tried patch command it didnt work for me. How to install Patch command..? < p/diffs/gcc-2.95.diff - this file is available in my working directory (/gnu/gcc-3.2.2/gcc/) under the same path [root@EXE-INDIA2 gcc]# patch -p1 < p/diffs/gcc-2.95.diff bash: patch: command not found So please help me how to do patching and successful configuration of GCC. Since there are many pascal types like Turbo, Borland, Standard, let know whether the HP pascal code can be successfully converted to C and get compiled in Linux using GCC. Please advice me. Thanks and regards, B.Gayathri

Sir, I received your reply and thank you very much. You wrote: Which one exactly did you try? 20020510 is a bit old, 20030830 is the msot recent release. gpc-20030830.i686-pc-linux-gnu.tar is a binary for Linux (you can just unpack it and don't have to compile it; but if you can compile the sources, it's generally better). Actually I dont know which tar file I have to take to compile Pascal source in Linux platform, as there are many tar files available in the web site. So please advice me in doing so. As per your advice I gave the configure command in /gnu/gpc-3.2.2/gcc/, but still the following same error occurred. *** ./configure detected GCC version 3.2.2. *** GPC 2.1 requires one of the following versions of GCC sources to build: *** *** 2.8.1 *** 2.95.1 *** 2.95.2 *** 2.95.3-5 *** 2.95.3-6 *** 2.95.3 *** 2.95.4 *** 2.95 *** *** (You can try to patch GCC manually by typing a command like *** `patch -p1 < p/diffs/gcc-2.95.diff' and patching possible rejects *** by hand before you run `./configure' again.) Sorry, I forgot to attach the source in my earlier mail and now I have attached. I did compilation of the pascal source, and the results as follows: [root@EXE-INDIA2 gpc-build]# gpc -c uttrace.p uttrace.p:1: numeric constant contains digits beyond the radix uttrace.p:1: warning: missing program header uttrace.p:1: parse error before `control' I agian tried with other command: [root@EXE-INDIA2 gpc-build]# gcc -c braccess.p gcc: braccess.p: Pascal compiler not installed on this system Still I am not clear whether I have installed and configured the GNU properly. I have attached a pascal source to get compiled in Linux. I want that simple file to be compiled successfully in Linux. I request you to help me in solving the installation problems. Awaiting your reply. Thanks and reagrds, B.Gayathri

Sir, I am working in HP Pascal (3000) application running in mainframe. I want to make the application run in Linux platform. For this I have to translate the pascal code to C and compile in Linux or use a direct Pascal compiler and compile in Linux. So I installed GNU and tried compilation of a pascal code. But I came across problems in installation and compilation. I need your valuable suggestion or advice to proceed my work. Please help me. Following are the information YOU need : GCC version - GCC 3.2.2 GNU Make version 3.79.1, by Richard Stallman and Roland McGrath.

I followed the installation instructions given in the site. After unpacking the zip file I did configuration of GCC by following command: BUG reported after configure: [root@EXE-INDIA2 gpc-build]# ../gnu/gcc-3.2.2/configure --enable-languages=pascal Configuring for a i686-pc-linux-gnu host.

--delphi bug?
by Prof A Olowofoyeku (The African Chief) 31 Dec '03

31 Dec '03

Hi This program fails to compile under '--borland-pascal' and '--delphi': program delphibug; {$delphi} { fails } {$borland-pascal} { so does this } CONST foo = 'PK'#5#6; { this is the offending line } begin Writeln ('OK'); end. This is the error I get (with gpc-20030830): "delphibug.pas:4: error: string concatenation without `Concat' or `+' is an extension delphibug.pas:4: error: of GNU Pascal" This error should not happen. If you remove the embedded condititionals, the program compiles fine both under BP and all versions of Delphi. Best regards, The Chief -------- Prof. Abimbola A.

Object type as function result?
by Markus Gerwinski 31 Dec '03

31 Dec '03

Hi folks, when declaring something like type tFoo = object ... end; Function bar ( ... ) = result: tFoo; ... is there a way to suppress this warning: optest.pas:53: warning: object type declared as function result type Resp. is there a good reason not to do so? (I've got a case here where it could indeed yield a more readable statement to return an object instead of a pointer to the object; but I don't know if it could cause compiler-internal problems.) Thanks, Markus
