Hi,

I need to build a 64 bit application from a lot of C++ source files.
I'm currently using g++ 4.1.1 on AIX 5.2, which I downloaded as
binaries from UCLA. In 32 bit mode everything works fine, but 64 bit
mode does not work, because the package does not include 64 bit C++
runtime libraries. (Exactly the same problem was reported in this
group under the subject "Link problems to stdc++ lib on AIX 5.2 with g+
+ 4.1.1 in 64 bit mode", but without a solution)

I tried using the 64 bit libraries from the AIX 5.3 package from UCLA,
but this works only for the most simple C++ programs. As soon as I
instantiate an fstream for example, the linker complains about an
undefined symbol that should be in /usr/ccs/lib/libc.a (symbol
__fd_poll). It looks like the 5.3 c++ libraries are not compatible
with the 5.2 c libraries (which is not really a surprise). So any
pointer to a compiled package of 64 bit C++ standard libraries for AIX
5.2 would be very (very!) helpful.

I'm still not desperate enough to try and compile the libraries
myself. But if I have to, is there a way to build the libraries only?
As far as I understand the build process, it builds the complete
package, including the compiler itself, which is not necessary for me,
as I already have a perfectly working compiler.

Thanks
Michael

Why not get it from IBM?

Thanks for your answer and link.

I'd love to get it from IBM, but following your link I find only
version 4.0.0 of the gcc/g++ package and the libraries. I need version
4.1.1. Am I missing something?

It's been our experience that the 4.0.0 package from IBM
is broken. the C++ std lib does not export many of the
STL symbols - causing link errors.

Thanks for the information, as I was considering to install 4.0.0 from
IBM instead of the current 4.1.1. The 4.0.0 package from IBM does
include a 64 bit C++ std lib, but a broken one won't help me a bit ...

Do you have any idea where to find compiled 64 bit libraries for gcc/g+
+ 4.1.1 and AIX 5.2?

Thanks
Michael

IBM allows you to try xlcpp for 60 days free. How about downloading it
and then building gcc yourself? Not nearly as easy and downloading
precompiled, but if it becomes your only option here's a link for you:

Thank you for your suggestion. As I wrote I already have a working
compiler (gcc/g++ 4.1.1), so I don't think that I need another one to
build the libraries, or can't I build the libraries with gcc itself?

Btw: I already tried to build the compiler and libraries, but ran into
compile errors (see my post "Error compiling gcc/g++ 4.1.1 on AIX 5.2"
in this group).

I succeded in building the libraries myself. It wasn't too difficult
after all, just run configure with parameters --disable-nls --disable-
bootstrap --enable-languages=c,c++ and without --disable-aix64 and the
libraries get built without bootstrapping the compiler. Important: use
bash als CONFIG_SHELL (export CONFIG_SHELL=/usr/local/bin/bash),
otherwise the build runs forever.

How about pdslib?

Thanks for your reply. Your link leads to the UCLA site I got the
binaries from in the first place (see my first post). Their package
for gcc 4.1.1 on AIX 5.2 does not include 64 bit c++ libraries. In the
meantime I was able to build the missing libraries from the source
(see post #8).
