Testing/debugging single Ada tests

[Richard Guenther]

Can someone of the Ada folks provide some info how I can get a debugging
session with a failing acats test?  Looking at the testsuite log file
I f.i. see c32001e failing and an (appearant) build line(s)

BUILD c32001e.adb
gnatmake --GCC="/space/rguenther/obj/obj3/gcc/xgcc 
-B/space/rguenther/obj/obj3/gcc/" -gnatws -O2 
-I/space/rguenther/obj/obj3/gcc/testsuite/ada/acats/support c32001e.adb 
-largs --GCC="/space/rguenther/obj/obj3/gcc/xgcc 
-B/space/rguenther/obj/obj3/gcc/"
/space/rguenther/obj/obj3/gcc/xgcc -c -B/space/rguenther/obj/obj3/gcc/ 
-gnatws -O2 -I/space/rguenther/obj/obj3/gcc/testsuite/ada/acats/support 
c32001e.adb

but neither of them is invokable from no existing directory (even if
you supply the correct path to the c32001e.adb file).  Like f.i.
within the testsuite/ada directory

../../gnatmake --GCC="/space/rguenther/obj/obj3/gcc/xgcc 
-B/space/rguenther/obj/obj3/gcc/" -gnatws -O2 
-I/space/rguenther/obj/obj3/gcc/testsuite/ada/acats/support 
acats/tests/c3/c32001e/c32001e.adb -largs 
--GCC="/space/rguenther/obj/obj3/gcc/xgcc 
-B/space/rguenther/obj/obj3/gcc/"
fatal error, run-time library not installed correctly
cannot locate file system.ads
gnatmake: *** make failed.

/space/rguenther/obj/obj3/gcc/xgcc -c -B/space/rguenther/obj/obj3/gcc/ 
-gnatws -O2 -I/space/rguenther/obj/obj3/gcc/testsuite/ada/acats/support 
acats/tests/c3/c32001e/c32001e.adb
fatal error, run-time library not installed correctly
cannot locate file system.ads
compilation abandoned

I see there's magic going on in the testsuite/ada/acats/run_acats and
run_all.sh scripts, but they cannot be invoked directly to set up the
environment.

So - help please!

Back to /ignore ada mode.
