STONE%GRIN1.BITNET@CUNYVM.CUNY.EDU ("Stone,John David") (02/02/89)
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?
