IDB V8.1-6 EM64T Build 20041117 not debug 64bit programs

[cbecker]

Hi folks,

I've try to debug 64bit programs generated with the intel fortran compiler for

EM64T, but the debugger says:

Unrecognized binary file format for file /home/teroknor/cbecker/feast/feast/applications/poisson/tst
Could not start process for tst

32bit applications seems to work.

How can I debug 64bit applications?

Many Thanks!

Bye,

Christian

Are you using idb? How does it announce itself when you start idb?

Hi Steve,

the intro message is:

Linux Application Debugger for Intel EM64T-based applications, Version 8.1-6, Build 20041117

The debugger program itself is a 64bit binary.

Bye,

Christian

I'm not familiar enough with this environment (Linux on EM64T) to help further. If someone else does not offer a suggestion, please report the problem to Intel Premier Support, and include a complete log of your build, showing all commands used and their output.

Same problem here:
$ idb pepe
Linux Application Debugger for Intel EM64T-based applications, Version 8.1-7, Build 20050128
------------------
object file name: deva
Unrecognized binary file format for file /home/becarios/mambru/pepe
Could not start process for pepe
No image loaded ... Recovering ...
(idb) q
$ file pepe
pepe: ELF 64-bit LSB executable, EM64T, version 1 (SYSV), for GNU/Linux 2.6.0, statically linked, not stripped

the binary was compiled using the latest intel fortan em64t compiler with the flags -O0 -g

Same here!

Unrecognized binary file format ....

Any solutions yet?

This is supposed to work (IDB is programmed to sense whether the debuggee is a 32-bit or 64-bit binary and adapt accordingly). I've discussed it with the Intel Debugger engineering team and they'd like to receive a reproducing test case.

Ideally, it should be reported through http://premier.intel.com/, but if that's prohibitive for some reason, then ifsomeone would please post a small source and corresponding makefile, then I'll submit a formal (internal) problem report to get this resolved ASAP.

Hi Folks,

I assume that it happens with every 64bit object file:

file tst.f90

program tst

print *,"Hello Intel"

end program

#file tst

I've been able to do this successfully using the latest version of IDB (i.e. IDB 9.0-10):

$ ifort -g -L/usr/local/gcc/lib64 -o tst tst.f90

$ file tst
tst: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.4.0, dynamically linked (uses shared libs), not stripped
$idb tst
Linux Application Debugger for Intel EM64T-based applications, Version 9.0-10, Build 20050413
------------------
object file name: tst

Reading symbolic information from /site/tst...done
(idb) w
1 program tst
2
3 print *,"Hello Intel"
4
5 end program
(idb) r
Hello Intel
Process has exited with status 0
(idb) q
$

This version of IDB is available in the latest Compiler 8.1 Update (as IDB 8.1-10) from Intel Premier Support.

Please let me know if that works better for you.

Hi folks,

when will this version be available? Wenn I log in to my premier
account, there is still the build version ...-027 with the old
debugger version 8.1-7.

Thanks & Bye,
