GNU m4 people,
When invoking m4 if you specify a file that does not exist
the return code when exiting is still 0 but you have an error
message. The man page shows that you will exit with 0
only if there are no errors. I am using version 1.4.3
compiled from source.
Example (no file bogus.m4 exists, using bash 3.0):
m4 bogus.m4 >bogus
if (($?!=0))
then
echo error
else
echo ok
fi
will output this:
m4: bogus.m4: No such file or directory
ok
It should output this:
m4: bogus.m4: No such file or directory
error
From the man page:
"EXIT STATUS
The following exit values shall be returned:
0 Successful completion.
>0 An error occurred"
I could not find what the exit status should be in the
info file at all; searching only turned up hits for
sysval related things and m4exit, neither of which
tells what m4 will return when it has an error.
If a missing file generates a message but is not an error,
then this should be either documented or fixed.
The README file says send bugs to [EMAIL PROTECTED],
but the web page here http://www.seindal.dk/rene/gnu/feedback.htm
says send them to [email protected]
I sent it to both places to be sure. I hope at least one
of the addresses was the correct place to send this bug report.
Thank you,
JGH
