Using redo with Ada

[Страхиња Радић]

Hi, I'm trying to use apenwarr/redo with GNAT (GCC Ada). I have the following
setup:

#default.o.do
gnatgcc -c -O2 $2.adb -gnata -o /dev/stdout

#all.do
redo-ifchange myprog

#myprog.do
FILES=main
FILES_ADB=$(echo $FILES | sed -e's/\(\<\S*\>\)/\1.adb/g')
FILES_O=$(echo $FILES | sed -e's/\(\<\S*\>\)/\1.o/g')
echo "$FILES_O" | xargs redo-ifchange
for f in "$FILES"; do
gnatbind $f
done
gnatlink $FILES_ADB -o myprog

The problem is that GNAT doesn't seem to like custom extension from $3, nor
/dev/stdout. I'm getting the following message from gnat1:

gnat1: incorrect object file extension

This happens regardless of whether I put /dev/stdout or $3 at the end of the
command in default.o.do.

Is there any way to trick GNAT into cooperating with redo?

Thanks in advance,
Strahinya Radich

Just use temporary file with required extension and rename it?

trap "rm -f $3.needed" HUP PIPE INT QUIT TERM EXIT
gnatgcc -c -O2 $2.adb -gnata -o $3.needed
mv $3.needed $3

Thanks Sergey, this worked! :)

My setup is now:

#all.do
redo-ifchange myprog

#default.o.do
trap "rm -f $2.o" HUP PIPE INT QUIT TERM EXIT
gnatgcc -c -O2 $2.adb -gnata -o $2.o
mv $2.o $3

#myprog.do
FILES=main
FILES_ADB=$(echo $FILES | sed -e's/\(\<\S*\>\)/\1.adb/g')
FILES_O=$(echo $FILES | sed -e's/\(\<\S*\>\)/\1.o/g')
echo "$FILES_O" | xargs redo-ifchange
for f in "$FILES"; do
gnatbind $f
done

gnatlink $FILES -o $3

P.S.: I seem to be not receiving any mails from Google Groups, I saw your answer
from the web interface instead and replied. Thanks again!
