With Yocto 1.1 M1 RC2 build, 'ld' case failed on all platforms, including qemu and real hardware. This case can run pass in Yocto 1.0 M4.

'ld' case will test the basic functionality of the `ld` command.

The error log of these failure cases show:
#######
<<<test_output>>>
Assertion 1 ..................
-)
Assertion 2 ..................
1,4c1,3
< gcc: error: x.obj: No such file or directory

You can find the scripts "Assertion 2" section in testcases/commands/ade/ld/ld01:

To reproduce the bug, you could download the LTP from
http://sourceforge.net/projects/ltp/files/LTP%20Source/ltp-20101031/ltp-full-20101031.bz2/download
and build it in target system. Then you could find ld01 under
"testcases/commands/ade/ld/ld01". Run it with commands "export TCdat=$LTPROOT/testcases/bin; ld01" you will get above
failure. $LTPROOT is a folder which you create for installing the ltp.

Comment 1 Nitin Kamble 2011-07-20 11:34:26 UTC

any particular reason your are not using latest ltp-full-20110606.bz2 ?

Comment 2 Nitin Kamble 2011-07-20 17:08:08 UTC

Looks like the gcc 4.6 has changed the error messages a bit as seen here:
< gcc: error: x.obj: No such file or directory
< gcc: error: y.obj: No such file or directory
< gcc: fatal error: no input files 
< compilation terminated.
---
> gcc: x.obj: No such file or directory
> gcc: y.obj: No such file or directory
> gcc: No input files 


While gcc 4.5 was giving as expected error messages, and gcc 4.6 is giving errors slightly differently. Possibly ltp test scripts need to be updated accordingly.


Similer error also comes for assertions # 4 for the testcase:

Assertion 4 ..................
1,3c1,2
< gcc: error: bad/x.obj: No such file or directory
< gcc: fatal error: no input files
< compilation terminated.
---
> gcc: bad/x.obj: No such file or directory
> gcc: No input files
FAIL -  ld failed to give expected error msg


Thanks,
Nitin

This need fixing LTP, as I talked with gcc person and he says that gcc is fine.

Comment 4 Yi Zhao 2011-07-21 20:30:15 UTC

I re-test this case with ltp-20110606 on 1.1 M2 RC3 build. This issue also happened.

I checked the testcases/commands/ade/ld/ld01 scripts, it is same with 20101031

Comment 5 Nitin Kamble 2011-07-21 22:23:42 UTC

Yi Zhao,
  As I mentioned earlier LTP need to be updated to reflect new error messages. It is not an issue with ld or gcc.

Thanks, Nitin. I think we could mark the bug as "NOTABUG" now since it's not gcc related.

Hi Yi,
Could you help to report the issue out to LTP mailing list.

Comment 7 Nitin Kamble 2011-08-08 09:15:46 UTC

marking it as notabug as discussed before.
