Cannot used optimization O3 in debug mode?

[Samba_Ba1]

Hello all,

I have a fortran code using XE-12 on windows with dual core intel processor.
My code does not give the same results on optimization O3 than on normal run without optimization (Od).
I wanted to debug it but when I try to build the O3 on debug mode it gives the following erros:

[bash]1>libcmt.lib(invarg.obj) : error LNK2005: __initp_misc_invarg already defined in LIBCMTD.lib(invarg.obj)
1>libcmt.lib(invarg.obj) : error LNK2005: __call_reportfault already defined in LIBCMTD.lib(invarg.obj)

1>libcmt.lib(invarg.obj) : error LNK2005: ___pInvalidArgHandler already defined in LIBCMTD.lib(invarg.obj)[/bash]

Is it possible to parallel debug with O3?
How can I debug otherwise?

THanks for your help in advance.

The messages state that you are linking both the debug library and the non-debug library. If this is accidental, I suppose a reason could be that you haven't rebuilt all your .obj with the debug option.

Tim,

I have actually rebuild the entire solution but it is still showing the errors.

Build your standard Release configuration.
However, turn IPO off (Inter-Procedural Optimizations)
And, include Debug symbols (IOW do not strip debug symbols). Inspect both compiler and linker properties.

Break points may be somewhat difficult to set due to inlining and code optimizations. Sometimes you may need to insert a call to a non-inlined function in which you can place a break point (and step out of to get to code of interest).

The errors have nothing to do with optimization. It is that, as stated earlier, you have a mix of debug and non-debug libraries being linked in. Are you using libraries built elsewhere (not the compiler libraries). These may be built with other libraries specified.

You can try linking to the non-debug libraries - they won't prevent you from debugging. Under Fortran > Libraries, specify "Multithreaded (/MT)" and not "Multithreaded Debug (/MTd)" for the run-time libraries. If you are including a C/C++ project, set its libraries (under "Code Generation") to the same value.

Steve,

Thank you very much.
You were right, it works now that I set the options to Multithreaded/MT.

Kind regards,
Samba.
