I am trying to compile the trunk (with the 4.8.2 merges) gcc on my 32 bit ubuntu 12.04 linux environment for armeabi / 
qnx 6.5.0. What would be the steps to do that? I tried both going under the linux-x86-o-ntoarmeabi and running make, and
 also configuring and making based on the configuration line of gcc4.8.1. And for both of them I get the following issue
:

source='../../libcpp/charset.c' object='charset.o' libtool=no DEPDIR=.deps depmode=gcc /bin/bash ../../libcpp/../depcomp

./libcpp/include  -c ../../libcpp/charset.c

make[3]: *** [charset.o] Error 1

Actually, what I was trying to o was, making a diff between the official gcc4.8.2 and the qnx trunk, and bringing those 
changes to the linaro gcc4.8 which has the ARM address sanitizer backported from the gcc4.9 line. When I try to compile 
that, I again get the same results as above.

Could someone please guide me for compiling gcc 4.8.2 on my local computer, linux x86/32, for the target QNX/ARMeabi?

Thanks!
