Again my puzzlement: I don't know what to look for. Please tell me *exactly* how to determine this. What command(s) should I type? What places in the file system should I go to to look for exactly what files? (For example, do you know if there is a Boogeyman program on your machine? Where would you look if you never heard of a Boogeyman? Where would you look if you *had* heard of a Boogeyman but didn't know where it was?) > If not, has Xcode 1.x been installed on that machine ? See above. 'Help' is, as usual on the Mac, pretty useless. google Xcode http://developer.apple.com/tools/xcode/ download "Xcode Tools 2.2" requires ADC Member Log In which I did not do. I don't know if this is a distraction or a help because I don't know what's on my machine at the moment.

Simple Pascal/XView program works!
by Chris Hicks 29 Dec '05

29 Dec '05

Thanks to the Chief, my simple XView example (that pops up an OK button and a string) now works. I attach my code, just in case anybody else is interested. I will be moving on to look at some more complicated examples and will post them on the web in due course. Thanks again for helping me. Best regards, Chris.

Trying to link gpc to xview (again!)
by Chris Hicks 29 Dec '05

29 Dec '05

I am beginning to make some progress (thanks for your help so far), but would be very grateful for some more help. My attempts at producing the XView - Pascal code are in Makefile, p.p, x_message.c and x_message.h. When I try to compile I get: $ make gpc -c p.p p.p: In main program: p.p:11: error: argument to `WriteLn' is of wrong type p.p:11: error: (Use `--cstrings-as-strings' to treat `CString' as a string.) make: *** [p.o] Error 1 I based this code on various examples, including some that demonstrated passing strings between C and Pascal that I produced with the Chief's help back in 2003 (http://www.staff.ncl.ac.uk/chris.hicks/programming.htm, pcallsc2 <http://www.staff.ncl.ac.uk/chris.hicks/programming.htm, pcallsc2> near the bottom). I don't understand what is happening here. My Writeln is similar to the 2003 example that worked, likewise I am not sure why the --cstrings-as-strings is not working. I am also wondering whether the Pascal in the 2003 example was quite right. Does the second getmem release the memory? program pascalcallsC(input,output); procedure world; external name 'c_world'; procedure w1(var i : integer; s : pchar); external name 'c_w1'; var i : integer; s : pchar; begin writeln("Hello world from Pascal"); world; writeln("Returned from C to Pascal\n"); i := 96; getmem (s, 260); { ahem - we need to allocate memory } w1(i,s); writeln("Returned from C again I = ",i); writeln("Return from C cstring = ",s); getmem (s, 260); { free this here, else memory leak on next line } s := "This is a CString"; { not really a good idea, IMHO } writeln("Trying out pascal ",s); end. Many thanks, Chris.

>Put "{$X+}" in the source code, or pass '--extended-syntax' at the >command line. I have changed the Makefile (attached) to include the command line option --extended-syntax, but I still get the same error message when I compile: $ make gpc -c p.p p.p: In main program: p.p:11: error: argument to `WriteLn' is of wrong type p.p:11: error: (Use `--cstrings-as-strings' to treat `CString' as a string.) p.p: At top level: p.p:15: error: syntax error before `more' make: *** [p.o] Error 1 The manual entry for --extended-syntax is "--extended-syntax same as --ignore-function-results --pointer-arithmetic --cstrings-as-strings -Wno-absolute (same as {$X+}). " so presumably I don't need the --cstrings-as-strings? Can you spot what's wrong? Many thanks, Chris.

Trying to link gpc to XView - crtbegin.o No such file or directory
by Chris Hicks 28 Dec '05

28 Dec '05

Thanks for your reply Chief. The command: gpc -print-file-name=crtbegin.o gives: crtbegin.o I also decided to go back to basics. You helped me do some C to Pascal, Pascal to C examples a couple of years ago (http://www.staff.ncl.ac.uk/chris.hicks/programming.htm). These all worked at the time. When I get these sorted I will go back to the XView problem. I tried one of the Pascal calls C programs that passes a string and that failed with the same error message: $ make gpc -o pcallc pcallc.p ccall.o --cstrings-as-strings /usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/../../../../i686-pc-cygwin/bin/ld: crtbegin.o: No such file: No such file or directory make: *** [pcallc] Error 1 Which version of Pascal would you recommend? I looked at http://www.gnu-pascal.de/binary/cygwin/ and found the most recent one in binary is gpc-20041017, based on gcc-3.3.3. gcc -v on my installation gives: $ gcc -v Reading specs from /usr/lib/gcc/i686-pc-cygwin/3.4.4/specs Configured with: /gcc/gcc-3.4.4/gcc-3.4.4-1/configure --verbose --prefix=/usr --exec-prefix=/usr --sysconfdir=/etc --libdir=/usr/lib --libexecdir=/usr/lib --mandir=/usr/share/man --infodir=/usr/share/info --enable-languages=c,ada,c++,d,f77,java,objc --enable-nls --without-included-gettext --enable-version-specific-runtime-libs --without-x --enable-libgcj --disable-java-awt --with-system-zlib --enable-interpreter --disable-libgcj-debug --enable-threads=posix --enable-java-gc=boehm --disable-win32-registry --enable-sjlj-exceptions --enable-hash-synchronization --enable-libstdcxx-debug : (reconfigured) Thread model: posix gcc version 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125) Is gpc compatible with the 3.4.4? Thanks again for your help. Chris.

Trying to link gpc to XView - crtbegin.o No such file or directory
by Chris Hicks 28 Dec '05

Hi, I have just reinstalled Cygwin which comes with gpc version 20040516, based upon gcc-3.3.3. The gcc version is 3.4.4. I am assuning that there are OK, because they were provided as binaries that were bundled in the Cygwin install. I have installed XView ( from xview-3.2p1.4-18c-cygwin.tar.bz2, from http://www.physionet.org/physiotools/xview/) and am trying to write a small example program to illustrate linking a Pascal program to XView. I attach my files (p.p, x_message.c and my Makefile). When I do a make I get the error message: $ make gpc -o test p.p x_message.o -I /usr/openwin/library -Lxview -LX11 p.p:6: warning: missing string capacity -- assuming 255 /usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/../../../../i686-pc-cygwin/bin/ld: crtbegin.o: No such file: No such file or directory make: *** [test] Error 1 I would be grateful for some help with this. Many thanks (and a happy New Year), Chris.

gpc on mac
by Tom Schneider 28 Dec '05

28 Dec '05

Adriaan: I downloaded from http://www.microbizz.nl/gpc.html GNU Pascal 3.4.5u2 installer for Mac OS X 10.4 PowerPC (PowerPC native and Intel cross compiler) (16.4 MB) to my Max OSX version 10.4.3 Power PC G4 It unpackaged ok and I have now /Developer/Pascal/ Then I went to /tmp and made: program tboy(output); begin writeln(output,'go to sleep!!'); end. I tried this: /Developer/Pascal/gpc345u2/bin/gpc test.p and got: [bluebird:~/now/t] tds% /Developer/Pascal/gpc345u2/bin/gpc test.p /usr/bin/ld: can't locate file for: -lSystemStubs collect2: ld returned 1 exit status Then /Developer/Pascal/gpc345u2/bin/gp test.p and got [bluebird:~/now/t] tds% /Developer/Pascal/gpc345u2/bin/gp test.p /usr/bin/ld: can't locate file for: -lSystemStubs collect2: ld returned 1 exit status Hmm. I could not locate simple examples of how to run the compiler. A small example test directory would help. Oh, also, the ReadMe.rtf that came in the package is not the same as /Developer/Pascal/README.rtf which is confusing. Regards, Tom Dr. Thomas D.

Delphi compat
by Prof A Olowofoyeku (The African Chief) 27 Dec '05

27 Dec '05

Hi The new Delphi 2006 is reported to have a new feature - records with methods - e.g., type TBlock = record procedure Foo(I: Integer); function Bar: TBlock; private Data: Integer; public property Color: Integer end; It also has something called static fields (for Classes), declared with "class var" (e.g., "class var foo : integer"). These are fields that belong to the type, rather than to any of its instances. I am not sure why either of these new features is necessary or useful, but perhaps they should be borne in mind with respect to Delphi compatibility (or perhaps not). Best regards, The Chief -------- Prof. Abimbola A. Olowofoyeku (The African Chief) web: http://www.greatchief.plus.com/
