Hi Ian,
the source code I found from gcc/configure (line:13420)
-----------------------------------------------
if test x$host != x$target
then
CROSS="-DCROSS_DIRECTORY_STRUCTURE"
......
fi
----------------------------------------------
When passing --target option: i686-pc-linux-gnu, this macro will not be defined, Because my pc is the same.
By default: when we run gcc --print-search-dirs
the last line like this:
libraries:.......;/lib/;......;/usr/lib/
I would like to build a gcc that do not search the system paths like /lib/ and /usr/lib.
Could you please show me the details of building such a gcc?
Thanks,
Xun Duan
