Re: GCC multilib building failure

[Xiaolong Tang <txlzte at neo dot tamu dot edu>]

Hi, I got the problem fixed by upgrading the developing tool for  
MAC.  (simply upgrading xcode...)
Then the assembler for x86_64 becomes ready.

However,  I got new errors reported during building libstdc++v3.  
(shown below)
I am googling for its resolution.
If anyone feeds me any advice, great appreciation!

-----------------------------------------------------------
appending configuration tag "CXX" to libtool
checking for exception model to use... configure: error: unable to  
detect exception model
make[1]: *** [configure-target-libstdc++-v3] Error 1
make: *** [all] Error 2
-------------------------------------

thanks
