gdb 7.3.1 and gdb 7.2 on AIX 6.1

gdb 7.3.1 and gdb 7.2 on AIX 6.1

[Perry Smith]

I'm trying to compile gdb 7.3.1 on AIX 6.1 using gcc 4.5.2.

The end of the make dies with:

The same error happens with 7.3.1 and 7.2 (the above snippet is from 7.2).

Searching the web did not hit anything connected to gdb.  The curious thing is that I compiled gdb 7.2 using a previous gcc of 4.2.4.

I notice the message "warnings being treated as errors" which might explain why, looking at the code, I don't see the problem.

Any suggestions of what is wrong?

Thank you,

Warnings change between versions of gcc.

Probably nothing is wrong, just gcc being too eager.
If you just want to build it, don't use -Werror.

Thank you.

For those watching on T.V. at home:

configure --enable-werror=no

but now I have another problem.  When I try "make install", I get 
the "You need makeinfo" message.

I've fiddled around with it a bit but I'm going to give up and just install
makeinfo and its friends.  I'm doing an "out of tree" build.  Maybe thats
part of the issue here.

This one makes me shake my head every single time - I always wonder
why they can't just print a warning and just continue, like most
projects do. Try:

    % make MAKEINFO=true
