Hi all,
I'm trying to port binutils (2.16) for a new target. After I have added the
files I need and edited .in .tgt and .am files I have run aclocal,
autoheader, automake and autoconf on each directory where I have made those
changes (except for the top src directory in which only the config.sub was
changed).
Then I have run configure, which seamed ok, and afterwards make and it
failed on building ld. Make exits whit error while doing configure in ld
with a message that it doesn't support the target and that I should check in
ld/configure.tgt for supported target?! I'm confused because I have added
the target there.
Can anybody help me out, please?
Best regards
Andrija Radicevic

Well, it's all just shell scripts. Run it under "bash -x" and see what
commands are being executed and see why it goes wrong.

I have tried this too, but it didn't help me much. Obviously, I haven't
explained the problem clearly enough.
1. the configure went ok (at least I didn't notice anything suspicuose)
2. make succeded to build everything (bfd, opcodes, gas ...) but ld
it exits with the message:
*** ld does not support target e1-coff
*** see ld/configure.tgt for supported targets
make: *** [configure-ld] Error 1
this is the message from ld/configure.tgt which is at the end of the block
case "${target}" in
...
esac
the thing is that I have the line
e1-*-coff) targ_emul=coff_e1 ;;
in this block, but the case somehow doesn't evaluate the alias e1-coff to
e1-*-coff

You need to make sure that config.sub translate e1-coff into, say,
e1-unknown-coff, ie. the command "./config.sub e1-coff" should print
"e1-unknown-coff". All target matches in the configure scripts assume
that config.sub has canonicalized the target name into the CPU-VENDOR-OS
form.

and this is exactly what it does, prints
e1-unknown-coff
shouldn't this match e1-*-coff?

Yes....
Lets have a look at these ld/configure.tgt and config.sub files of
yours. Can you tar them up, zip them up and then post them ?
Cheers

Hi Andrija,

Right, so the config.sub file you sent does translate "e1-coff" into
"e1-unknown-coff" and the configure.tgt file does recognise a target of
"e1-unknown-coff".
Since the error message that you get from configure.tgt show that it
does not recognise "e1-coff" it follows that this translation from
"e1-coff" into "e1-unknown-coff" is not being performed. You need to
check what is happening in the ld/configure script around these lines:
# Canonicalize the secondary target names.
result=`$ac_config_sub $targ_alias 2>/dev/null`
if test -n "$result"; then
targ=$result
else
targ=$targ_alias
fi
. ${srcdir}/configure.tgt
This starts at line 9702 in the version of the configure file that I
have here. Presumably the invocation of "result=`$ac_config_sub
$targ_alias`" is not working. You need to find out why.
Cheers
Nick

I have found the part in my configure file, dough it looks a little bit
different
# Canonicalize the secondary target names.
result=`${CONFIG_SHELL-/bin/sh} $ac_config_sub $targ_alias 2>/dev/null`
if test -n "$result"; then
targ=$result
else
targ=$targ_alias
fi
. ${srcdir}/configure.tgt
obviously it must end up in the else branch (targ=$targ_alias) as you
already said. Now I have to figure out why this happens.
Thanks for your help.
greetings
Andrija

Hi,
It turnd out that
${CONFIG_SHELL-/bin/sh} evaluates to /bin/sh
and
$ac_config_sub to /bin/sh ../../binutils-2.16/ld/../config.sub
which together obiously results with an awkward construct
After I have removed ${CONFIG_SHELL-/bin/sh} from that particular line in
the ld/configure script, ld was built. Now, I wonder what went wrong? I
suspect that the autoconf (2.59) and automake (1.9.2) versions I was using
messed the thing up. I haven't built those myself, they came with the Fedora
Core 3 distribution I have installed on my machine.
regards
Andrija
