build errors for download gcc-2.95.3-tar.gz for host m68k-motorola-sysv

[Beere, Chris]

Hello,
         The standard gnu C compiler on the Motorola delta series is 2.4.5,
a very old version. I downloaded 2.95.2 and tried to build it, it failed
miserably. I installed 2.8.1 and this built OK. I retried 2.95.2 using 2.8.1
and after fixing some problems in libiberty/setenv.c it almost went the
distance, failing in the compile of the C++ libraries. I had noticed a later
version 2.95.3 which I also tried. This had the same problems. The following
extracts from the make.log file after executing the make with:-

nohup make CFLAGS='-O'  LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2
-fno-implicit-templates' bootstrap >>make.log 2>&1

Error at line 70 was it complaining about register???? I defined '#define
register' to get rid of them.
Before 2.8.1 was installed stdlib.h did not exist. After 2.8.1 was installed
it did exist, but did not contain definitions for NULL and size_t.
I forced inclusion of sys/types.h snd stdio.h rather than stdlib.h.
I added #include <malloc.h> to stop warnings about use of malloc().

These changes allowed setenv to compile cleanly:-

  gcc281 -c -DHAVE_CONFIG_H -g -O2 -I.
-I../../gcc-2.95.3/libiberty/../include  
 ../../gcc-2.95.3/libiberty/setenv.c -o pic/setenv.o

Why did it complain about register? This is valid.

It then went on to build the compiler cleanly xgcc, stage1/xgcc and
stage2/xgcc. It failed again compiling the C++ libraries:-

The interesting text from streambuf.h is:-


#ifdef _IO_THROW
    void _throw_failure() const { throw new ios::failure(this); }
#else
    void _throw_failure() const { }
#endif
    void clear(iostate state = 0) {
        _state = _strbuf ? state : state|badbit;
        if (_state & _exceptions) _throw_failure(); }
    void set(iostate flag) { _state |= flag;
        if (_state & _exceptions) _throw_failure(); }
    void setstate(iostate flag) { _state |= flag; // ANSI

_throw_failure is a method not a member, why the error 'has no member named'
?

Will you enlighten me as to what the errors mean, and give me a possible fix
please?

I am trying to install C++ to learn the language so my C++ knowledge is
basic.
