Thank You.
I figured out how to run the test (I didn't have 'dejagnu' installed before)
and I got to run the script.exp and all the CRC stuff failed (not 
unexpectedly),
while the rest were OK.

==============

Had a problem with my system disk, and decided to upgrade
to from Ubuntu 18.04 to 22.04 and installed ubuntu-mate-desktop

Now everything fails :-(.

==============

Running 
/home/ulf/projects/binutils/binutils-gdb-digest/ld/testsuite/ld-scripts/script.exp 
...
FAIL: script
FAIL: MRI script
FAIL: MEMORY
FAIL: MEMORY with symbols
FAIL: ld-scripts/asciz
FAIL: ld-scripts/ascii
FAIL: ld-scripts/crc64-ecma
FAIL: ld-scripts/crc64-iso
FAIL: ld-scripts/crc64-poly
FAIL: ld-scripts/crc64-polyi
FAIL: ld-scripts/crc32
FAIL: ld-scripts/crc32-poly
FAIL: ld-scripts/crc32-polyi
FAIL: ld-scripts/pr20302
FAIL: ld-scripts/output-section-types
FAIL: SEGMENT_START expression not absolute (default)
FAIL: SEGMENT_START expression not absolute (overridden)

It looks like there is some basic error.
I get this: "WARNING: Couldn't find tool init file", but I do not know
if it is significant.

==============

If I get a FAIL, is there a log to look at to find out why it fails?

==============

Best Regards

Ulf
