I found the file at http://www.gnu-pascal.de/binary/install-gpc-binary Can any of the binaries at http://www.gnu-pascal.de/binary/ run on an amd64? Tom Thomas D.

I'm looking at http://www.gnu-pascal.de/stable/gpc-2.1.tar.gz The INSTALL file says: > - Run the script `install-gpc-binary', available from > `http://www.gnu-pascal.de/current/binary/'. but that link brings me to: http://www.gnu-pascal.de/alpha/binary/ which says: > Not Found > The requested URL /alpha/binary/ was not found on this server. so the documentation is out of date.

07 Jul '16

Hello! I was trying to find any repository with the project's source code, but after too many attempts I found nothing. Although the source code of the project *is* available, yet I can't find the history of the project. Can somebody please point me to the correct direction? Thank you in advance! --- Christos Kontas, kontas(a)ceid.upatras.gr

binding to non-existent file
by Paul Isaacs 31 Mar '16

31 Mar '16

Hello, I am following the example from page 94 of the GNU pascal manual. bind( f,b); b := binding( f ); b.bound appears to be true even though the file does not exist although the example indicates otherwise. I have duplicated the example - it finds a non-existent file. Is the example wrong ( the same example is in the standard )? Regards, Paul Isaacs

Hello Chief, hello Peter, defining Variables and exporting them DID WORK! I really have to thank you and I express, I do! I will now start my project, it is an old integrated development sytem for Motorola M6800 Microprocessors including an assembler and a simulator, first started in 1981. Thank you again (I learned a bit) Mathias Uhle -- mathias.uhle(a)tu-dortmund.de

Well, befor the diverse compiling efforts I checked that ncurses was installed and found that: libncurses5, libncurses6,ncurses-devel and ncurses-utils were installed! Further a "find" revealed that there were copies of "panel.h" in /usr/include/ncurses /usr/include/ncurses6/ncurses /usr/include/ncurses6/ncursesw /usr/include/ncursesw So thas before I called for help I added now: libncurses5-32bit, ncurses6-32bit and ncurses-devel-32bit. althoug it is an 64-bit system. The effect on compilation was nil! I now copied "panel.h" into my testdirectory: no effect on compilation! Next try: put it into the source-directory of "crtc.c": no effect! GPC still complains not to find "panel.h" Feel a bit helpless. Mathias Uhle PS.: I tried even an strace gpc .... and searched the output for "panel.h": did find none -- Univ.-Prof. i.R. Dr.-Ing.

Problems when compiling "crtdemo.pas"
by mathias uhle 29 Mar '16

29 Mar '16

Hello out there trying to compile the example-program "crtdemo.pas" produces an awful lot of errors for me. My problem is: I am by no means accustomed to "c". The purpose of my attempt is to transfer a very old program from Novell-Dos to SuSE 13.2 The program heavily relies on what is now ncurses. But even that is new to me. I just tried: gpc --automake -ocrt crtdemo.pas The running 64-Bit version of the GPC-compiler and the "crtdemo.pas" are from: "https://openSUSE Build Service > Projects > home:TrevorBl > gpc > Binaries > gpc-20070904-185.1.x86_64.rpm" This rpm installed properly and works fine with a wealth of my programs running on an old Athlon 64 3200+ Mem: 3G Any help possible?

In ISO Pascal you have variable parameters and procedural parameters. They allow you to do most things possible with address operator, but not all and in a different way. > I am chugging away writing a 10206 compliant compiler using GNU pascal > and suddenly thought that using extensions to enable the writing of a > compliant compiler was not a great way to advertise 10206. I recognize > that the extensions are there because they are useful - but - do they > also flag 10206 as a poor standard to use? Well, 10206 was deliberately limited. Practically, decent compiler should allow writing runtime library. But ISO 10206 misses extentions needed for writing functions like 'new'. This does not mean that this is poor standard, just that for some purposes you may need extentions. > I am hesitating to use extensions because the target of the compiler > will be embedded processors.They are problematic to debug so you want to > have the compiler produce code that is as bug free as possible.

I will use jumps if I have to but they are > far from handy. Some comments: - I would just abort parse after first syntax error, so no need to re-sync - @ operator alone is safe. One can even claim that it is less error prone than var parameters. What is unsafe is pointer arithmetic as typically done in C (one can implement safely C pointer arithmetic but due to slowness and incompatibility with common practice safe implementation it is almost unused). - For Arduino you will need extensions to access hardware and on Raspberry Pi you will need to access foreign libraries. -- Waldek Hebisch
