🚀 go-pugleaf

        I have been working on installing version 1.32.0 of GNU C++ on a
network of Sun-3 workstations under SunOS 4.0.1.  I didn't encounter much
trouble during installation, but the resulting compiler doesn't compile
anything.

        Here's a small example.  Suppose the file foo.c contains the
following four lines:

main()
{
    int foo = 0;
}

I invoke the compiler with the command

gauss% /usr/local/g++ -o foo foo.c

and the compiler replies

foo.c:2: parse error before `{'

and quits.  Preprocessing is successful; you can say

gauss% /usr/local/g++ -E foo.c

and get

# 1 "foo.c"
main()
{
    int foo = 0;
}

        The results of attempting a compilation vary a little from one
source code file to another.  Because we didn't receive either streams.h or
stdio.h, I tried to adapt the SunOS stdio.h so as to try out a basic
"Hello, world" program:

#define BUFSIZ  1024
#define _SBFSIZ 8

extern  struct  _iobuf {
        int     _cnt;
        unsigned char *_ptr;
        unsigned char *_base;
        int     _bufsiz;
        short   _flag;
        char    _file;
} _iob[];

#define _IOFBF  0
#define _IOREAD 01
#define _IOWRT  02
#define _IONBF  04
#define _IOMYBUF        010
#define _IOEOF  020
#define _IOERR  040
#define _IOSTRG 0100
#define _IOLBF  0200
#define _IORW   0400

#define NULL    0
#define FILE    struct _iobuf
#define EOF     (-1)

#define stdin   (&_iob[0])
#define stdout  (&_iob[1])
#define stderr  (&_iob[2])

#define putc(x, p)      (--(p)->_cnt >= 0 ?\
        (int)(*(p)->_ptr++ = (unsigned char)(x)) :\
        (((p)->_flag & _IOLBF) && -(p)->_cnt < (p)->_bufsiz ?\
                ((*(p)->_ptr = (unsigned char)(x)) != '\n' ?\
                        (int)(*(p)->_ptr++) :\
                        _flsbuf(*(unsigned char *)(p)->_ptr, p)) :\
                _flsbuf((unsigned char)(x), p)))
#define putchar(x)      putc((x),stdout)

int puts (char* s)
{
  int ch;
  while (ch = *s++)
    putchar(ch);
  return putchar('\n');
  }

main()
{
    puts("Hello, world!\n");
}

If this is in hello.c, then the compiler behaves as follows:

gauss% /usr/local/g++ -o hello hello.c
hello.c:5 Segmentation violation
/usr/local/g++: Program c++ got fatal signal 11.

In this case a core file is dumped, which ls -l reports as being of
stupendous size:

-rw-r--r--  1 stonej   251913018 Feb  1 13:00 core

        Possibly some details about the installation will help.  It took me
three tries; the first one two failed at the point where c++ is linked,
because I was using our standard SunOS C compiler instead of GNU CC, and
the standard compiler was unable to locate the meaning of the symbol
___eprintf.  (It took me two attempts to work this out; after the first attempt
I misdiagnosed the problem as a consequence of my failure to create a
symbolic link from /home/hilbert/gnu/gcc to /home/hilbert/gnu/gcc-1.32,
which is the directory in which GNU CC got unpacked.)

        For the installation of GNU C++, tm.h was an edited version of
gcc-1.32/tm-sun3.h in which all of the references to crt0.h were replaced
with references to crt0+.h.  The md file was gcc-1.32/m68k.md.  The only
change I made in the Makefile was to change the definition of CC to
/usr/local/gcc.

        Here's a transcript of how the how the installation went.  As we
begin, gcc and bison have already been installed in /usr/local, which is on
the search path.

        As this record shows, I did run into a couple of difficulties, but
they shouldn't have been fatal:  The README file directed me to cd into the
g++ subdirectory on two different occasions, only the first of which was
necessary or possible.  Our version of the software came without a version
of tm-sun3.h that referred to crt0+.o; I edited in the references to it
using sed.

        Any suggestions?
