             Bug #: 52733
           Summary: Cannot compile gcc/g++ on Mac OS X 10.6.8
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: chris.jonesey@gmail.com


I downloaded GCC 4.7.0 released [2012-03-22] and was unable to build gcc/g++.
I used the following configure command:

% ./configure --prefix=`pwd`/inst --enable-languages=c,c++

I also tried it without the --enable-languages with the same result.  The error
I received is below.  I would be happy to provide any other information that is
useful to tracking down this error.

Running configure inside the source directory is not supported
http://gcc.gnu.org/wiki/FAQ#configure

Are you sure you want to use a subdir of the sources as the --prefix arg? That
looks odd too.  You still shouldn't get an internal compiler error though.

Per se, the issue is now moot because both in mainline and in 4_7-branch we
don't use std::log(2.0) anymore. Still, something may well be flaky, at least
for this specific version of darwin ("Snow Leopard", right?) vs the
optimization of the mathematical functions for compile-time constants... If
current 4_7-branch builds fine - I don't see why it should not - then it should
be pretty easy to create a small reproducer, just a tiny function calling
std::log(2.0).

For the record: on Lion things seem in pretty good shape for current gcc-4_7:
builds is fine and std::log(2.0L) also works at any optimization level.

We can close this.
