Well, I (think I) finally figured out how to proceed with that config.sub.
In my very case, I want to compile Insight for PC as host and
mips2_fp_le as target. The only thing which is important, is that the
configuration file must be able to find the compilers for the target given.
So, what I did was the following:
* I added the following section into the config.sub file (in the "case
$basic_machine in" section):
mips2_fp_le)
basic_machine=$basic_machine-unknown
os=-linux
;;
I added it just after the following lines:
mips3*)
basic_machine=`echo $basic_machine | sed -e
's/mips3/mips64/'`-unknown
;;
* This will result in searching for "mips2_fp_le-gcc",
"mips2_fp_le-g++", and so on during the run of "./configure
--target=mips2_fp_le"
* The only thing that is important, is that ./configure can find the
compilers for the target given. So, ./configure must be able to fine
"mips2_fp_le-gcc", "mips2_fp_le-g++", and so on, to be able to compile
gdb for the target.
Therefore, it's best to make sure the path is extended to the
location where ./configure is supposed to find all the executables for
that target.
* Once this is done, I should have the Insight GUI running on the PC,
while the gdb should have been compiled for the mips2_fp_le target.
I still have to test it, though (I'm at home and the set-up is at the
office), but I will come back with the results of this "experiment".
