IDB doesn't work under Mac OS X

[mattnotting]

I got an interesting problem on my desktop minimac. It has a Mac OS 10.7.2 system. I installed a trial version of Intel Fortran Composer XE 2011 for Mac OS. I just wrote a simple fortran program fout.f90 to test it. The program is

program fout

implicit none

write(*,*) 'Hello'

stop

end

ifort works fine. It can generate a executable that can be run. However, when I use

idb fout

it tells me that

Intel Debugger for applications running on Intel 64, Version 12.1, Build [76.205.11]

------------------

object file name: fout

Reading symbols from /Users/jgeng/fout...done.

Could not start process for fout

No image loaded ... Recovering ...

I've checked the intel forum to try to find the problem solution. It seems there is no answer for this. IDB seems to read successfully the debug symbols, but fails to start. Interestingly, GDB can start normally. Why?????

Could anybody help me? Thanks

Yes, this is indeed a bug. I will start a bug report.

THere is a workaround:

ifort -g -save-temps -fpic -Wl,-no_pie -o hello hello.f90

idb ./hello

I have a bug report started and am escalating this issue.

Hello,

I'd like to add the following information for clarification:
IDB cannot debug PIE enabled applications, neither for Linux* nor for Mac OS* X. For the latest Mac OS* X 10.7 (Lion) PIE is the default.
Hence if you want to debug an application it must be built without PIE explicitly. Please note that release versions still can and should be built with the default (PIE enabled).

Usually you'd turn off PIE with -fno-pie switch; unfortunately this switch is broken for Intel C/C++ & FORTRAN Compiler and hence you have to provide -fpic -Wl,-no_pie as workaround. We're currently working on that (DPD200225616).

Sorry for the inconvenience & best regards,

Georg Zitzlsberger
