[Bug libstdc++/26297] boostrap fails with invalid cast compiling libstdc++ with --disable-nls on AIX

------- Comment #2 from rguenth at gcc dot gnu dot org  2006-02-15 10:42 -------
This looks more like a libstdc++ issue, maybe not even AIX specific.  I'm
trying to reproduce on i686-linux.

(In reply to comment #0)

> c++locale.cc:61: error: invalid conversion from `const char*' to `char*'
> c++locale.cc:61: error:   initializing argument 1 of `float strtof(char*,

A few comments: first, I seriously doubt --disable-nls is relevant, because the
error happens in the above line, where I cannot see the involvment of nls. That
said, you gonna need --enable-clocale=generic, on linux, to enable that code,
which is part of the generic locale model (used by default on AIX). Last but
not least, I don't think on linux - and many other targets for that matter -
the first parameter of strtof is of type char* (vs const char*) ...

David, can you please have a look? Certainly we have succesful reports:

  http://gcc.gnu.org/buildstat.html

In the meanwhile, submitter should check that is following the target-specific
installation notes:

AIX 4.2 probably cannot be supported by current versions of GCC.  If libstdc++
doesn't work on AIX 4.2, then it doesn't work.  I do not have access to any AIX
4.2 system and AIX 4.2 was removed from IBM support a long time ago.  libstdc++
probably relies on more modern Posix-conformant headers than were shipped with
AIX 4.2.

this happens on 3.3.6 too, but I read 
http://gcc.gnu.org/ml/gcc/2003-10/msg00110.html

who was able to build 3.3.1 on an even older system. Differences are that he
disabled multilib and shared libraries. I don't see how that could affect me
though.

------- Comment #9 from dje at gcc dot gnu dot org  2006-02-18 23:16 -------
libstdc++ configuration may have detected that the particular feature causing
problems was not present or the header may not have defined the function at
all, causing libstdc++ to provide its own implementation.

The usual problem is that a system claims it supports some feature, but does
not implement it correctly or does not declare the standard function correctly.
 Providing something wrong generally is worse than not providing it.  GCC does
have some functionality to go back and fix up headers, but GCC probably does
not know about this particular problem.

The problem appears to be that AIX 4.2 declares strtof() in
/usr/include/stdlib.h as

extern float    strtof(char *, char **);

instead of 

extern float    strtof(const char *, char **);

In other words, missing the "const".  You could manually fix the header during
the build process between building the compiler and building the libraries, by
changing the copy of the stdlib.h header in the gcc/include subdirectory of the
build.  GCC uses its copy of the header if present.

------- Comment #10 from multix at gmail dot com  2006-02-21 17:00 -------
thanks. I fixed the header as you suggest and typed the same boostrap make
command again and left it running overninght. I found that gcc had completed
build and I installed.
Trying to compile a hello world program like
#include <iostream>

int main ()
{
        std::cout << "hello";
        return 0;
}


yields me
g++ hello.c 
ld: 0711-317 ERROR: Undefined symbol: __gxx_personality_v0
ld: 0711-317 ERROR: Undefined symbol: .std::basic_ostream<char,
std::char_traits<char> >& std::operator<< <std::char_traits<char>
>(std::basic_ostream<char, std::char_traits<char> >&, char const*)
ld: 0711-317 ERROR: Undefined symbol: .std::ios_base::Init::Init()
ld: 0711-317 ERROR: Undefined symbol: .std::ios_base::Init::~Init()
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
collect2: ld returned 8 exit status

I don't think this is now related to the bugs we are discussing here ? Since
the gcc 3.04 has known problems too (ld: 0711-317 ERROR: Undefined symbol:
std::string::_Rep::_S_max_size) I tried the program with 2.95 and it works.

I wonder know if your fix is safe and if it could be integrated in future
stable versions of 3.4x and 4.x and that there are other problems to solve
instead.
