gcc 4.6.0 breaks

gcc 4.6.0 breaks

[Bill Cunningham]

    I tried to mail in a log concerning the error from this compilation and 
the mailer daemon mailed it back and said it was too large. It was 
concerning not knowing something about the right kind of object files. 
ldconfig -v showed that ld.so knows where the libraries are.

I'm not going to keep repeating myself, check the archives
http://gcc.gnu.org/ml/gcc-help/2011-06/

Until you've bothered to note the actual error this is a waste of
everyone's time.

In order to answer a question like that we would need to see the actual
error that you got.

References to lib/cpp in config.log should be ignored.  In fact,
config.log should generally be ignored.  Only if you get some other
errors should you look at config.log, and then you should look at the
relevant decisions.

    I got an error about the C++ preprocessor and lib/cpp. I don't quite 
understand a lot of these errors. Where again should I look for the error 
script? What's it called?

No, did you not read what the wiki FAQ says?
As it says there, "You might recognize that several test programs
failed during the configuration, but some of these failures are
non-critical."
You don't need cloog and ppl.

Also, your config.log shows you're running ../configure
Please read http://gcc.gnu.org/wiki/FAQ#configure and the installation
docs it links to: http://gcc.gnu.org/install/configure.html

I also explained at http://advogato.org/person/redi/diary/240.html
that you must run configure from outside the source directory.

The docs are there to help you. Please read them.

You do not need cloog and ppl.  They are optional.  Do not be misled by
the errors in the top-level config.log file.  The configure script
determines whether cloog and ppl are available by running tests.  When
those tests fail, gcc is built to not use cloog and ppl.

gcc installs cpp in the bin directory.  It does not install it in the
lib directory; why should it?  gcc does not have a libcpp.a file; why do
you expect one?

    I had the script and sent it in and got back a message saying the system 
wouldn't take large mail files. Now I might need cloog and ppl too. I think 
they are required and my C preprocessor fails sanity checks. cpp is in the 
bin directory but there's nothing in the lib directory. Shouldn't there be a 
cpp or libcpp.a there or something. When I compile gcc's I get no 
pre-processor.

Wrong config.log, that's the top-level one, which exited with status 0
(as shown at the end)

You need to look in the config.log which actually failed, as explained
at http://gcc.gnu.org/wiki/FAQ#configure_suffix
As it says there, "You might recognize that several test programs
failed during the configuration, but some of these failures are
non-critical."

I already suggested that you look in $target/libgcc/config.log, for
your system that would be i686-pc-linux-gnu/libgcc/config.log

That might not be the right directory, it's just my guess, you should
look in the directory where configure failed. Again, that's explained
at http://gcc.gnu.org/wiki/FAQ#configure_suffix

If you want help you really need to be less vague than "not knowing
something about the right kind of object files" and you need to
(carefully!) read the documentation which people have gone to the
trouble of writing.

    Well here is the configure log. Maybe that means something. Something is 
missing that is needed or I'm not using the right switches.
