             Bug #: 54423
           Summary: building trunk on Darwin 12.1 fails in building
                    libraries
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3
         Component: other
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: nenad@intrepid.com


Building the trunk on Mac OS X 10.8.1 (Darwin 12.1.0) fails.
Configuring libraries fails with the following error (e.g. libatomic):

configure:3477: checking for C compiler default output file name
configure:3499: /eng/upc/dev/nenad/gcc-trunk/bld/./gcc/xgcc
-B/eng/upc/dev/nenad/gcc-trunk/bld/./gcc/
-B/usr/local/x86_64-apple-darwin12.1.0/bin/
-B/usr/local/x86_64-apple-darwin12.1.0/lib/ -isystem
/usr/local/x86_64-apple-darwin12.1.0/include -isystem
/usr/local/x86_64-apple-darwin12.1.0/sys-include    -g -O2   conftest.c >&5
Undefined symbols for architecture x86_64:
  "start", referenced from:
     -u command line option
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status

The above uses the following link lines (produces with -v switch):

/eng/upc/dev/nenad/gcc-trunk/bld/./gcc/collect2 -dynamic -arch x86_64
-macosx_version_min 10.8.1 -weak_reference_mismatches non-weak -o a.out

This test links if I add "-lcrt1.o" on the command line. I have the latest
Xcode loaded and my Mac is up to date.

Has there been any attempt to confirm/resolve this bug? As it stands I am not
able to build gcc on the latest Mountain Lion OS.

I verified that I have the latest Xcode (4.5). I verified that I installed the
latest development CLI tools (via Xcode and manual download).

* I see that 10.8 SDK directory exists under Xcode App - but not under
/Developer
* cc running is llvm - 4.2.1
* I see that it links with the following command:

 /Developer/usr/llvm-gcc-4.2/libexec/gcc/i686-apple-darwin11/4.2.1/as -arch
x86_64 -force_cpusubtype_ALL -o
/var/folders/z7/83zx0wdj4cx644rg7p7kgwb80000gn/T//ccDk1do9.o
/var/folders/z7/83zx0wdj4cx644rg7p7kgwb80000gn/T//ccDTslhw.s
 /Developer/usr/llvm-gcc-4.2/libexec/gcc/i686-apple-darwin11/4.2.1/collect2
-dynamic -arch x86_64 -macosx_version_min 10.8.2 -weak_reference_mismatches
non-weak -o t -lcrt1.10.6.o
-L/Developer/usr/llvm-gcc-4.2/lib/gcc/i686-apple-darwin11/4.2.1/x86_64
-L/Developer/usr/llvm-gcc-4.2/lib/gcc/i686-apple-darwin11/4.2.1
-L/Developer/usr/llvm-gcc-4.2/lib/gcc/i686-apple-darwin11/4.2.1/../../..
/var/folders/z7/83zx0wdj4cx644rg7p7kgwb80000gn/T//ccDk1do9.o -lSystem -lgcc
-lSystem

Note the "-lcrt1.10.6.0" on the command line. 

Is linking with crt1.10.6.0 the right fix for Mountain Lion?

Apple has changed how Xcode is configured and /Developer is no longer used.
Make sure you have installed the latest Xcode, the matching Command Line Tools
from within the Preferences panel of the Xcode application and then have
executed...

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

You are likely using some pre-Mountain Lion of the CLI in the deprecated
/Developer directory.

I removed /Development and /Application/Xcode.app then installed it again. Now
I am able to build gcc again. Thank you.

Problem fixed with a clean install of Xcode.
