Re: Building a cross-compile tool chain for mips-elf

[Alfred von Campe]

I'm still having the problem I sent to the list last week (see  
below), and the need to build a working cross-compiler is becoming  
greater.  Is this the wrong list to ask about how to build a cross- 
compiler?  I find it hard to believe that mips-elf is not a supported  
target.  I just noticed that the target with the problem appears to  
be libstdc++, which we may not even need.  But I would still be  
interested in building a more recent, working cross compiler tool  
chain, so any help is much appreciated.

Thanks,
Alfred
