Subject: binutils: error message about /usr/lib/debug/usr/lib/crt1.o when linking executable without main

Date: Sun, 03 Jan 2010 12:19:30 +0200

Package: binutils
Version: 2.20-4
Severity: normal

When trying to link an executable without main, instead of getting the simple
error message that the symbol 'main' was not found, I get a lengthy error
message about crt1.o.
This made me believe there was something wrong with my libc, so I reinstalled
it, but I got the same error message after that too.
Then I noticed that the real problem was that I forgot to add an object file on the link command line
(which defines main), and not something wrong with my libc.

Testcase:
$ echo "int foo(){return 0;}" > foo.c
$ /usr/bin/gcc foo.c

I started getting this error message with binutils 2.20, the previous ones
didn't give me this error message.
For example this version shows the correct error message:
$ ld -v
2.19.51.20090805
$ gcc-4.3 foo.c
/usr/lib/gcc/i486-linux-gnu/4.3.4/../../../../lib/crt1.o: In function `_start':

collect2: ld returned 1 exit status

This one shows the wrong error message pasted above:

Subject: Same here

Date: Sat, 27 Aug 2011 22:24:26 +0200

I get the same thing here, today, binutils 2.20.1-16 on amd64 and ppc.

Bloody annoying; I knew I had no main() yet, but the error messages made me
suspect I had some deeper problem, and I did a lot of fruitless
investigations before I googled the error message and found this.
