[Bug libstdc++/26297] boostrap fails with invalid cast compiling libstdc++ with --disable-nls on AIX
--- 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_ostreamchar,
std::char_traitschar std::operator std::char_traitschar

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.

--- Comment #8 from multix at gmail dot com 2006-02-18 23:04 --- 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. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26297

--- 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 floatstrtof(char *, char **); instead of extern floatstrtof(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. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26297

--- Comment #7 from dje at gcc dot gnu dot org 2006-02-17 20:05 --- 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. -- dje at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||WONTFIX http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26297

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*) ... -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26297
