ISSM IQDC compiler __attribute__

[Munchoy_W_Intel]

I am using ISSM 2015 version 2015.3.022 in a VM running Ubuntu OS. I did not use Eclipse to build my source code and instead, I build the code from a shell by calling the make utility.

Everything seems working fine except that there are a lot of warnings like this:

====================================================================================

/opt/intel/issm_d1000_2015.3.022/tools/compiler/include/stdlib.h:122:65: warning: unknown attribute '__warning__' ignored [-Wattributes]

char * _EXFUN(_mktemp_r, (struct _reent *, char *) _ATTRIBUTE ((__warning__ ("the use of `mktemp' is dangerous; use `mkstemp' instead"))));

^

/opt/intel/issm_d1000_2015.3.022/tools/compiler/include/_ansi.h:101:42: note: expanded from macro '_ATTRIBUTE'

# define _ATTRIBUTE(attrs) __attribute__ (attrs)

^

/opt/intel/issm_d1000_2015.3.022/tools/compiler/include/_ansi.h:65:35: note: expanded from macro '_EXFUN'

# define _EXFUN(name, proto) name proto

=====================================================================================

From the warnings, It looks like '__warning__' is not a recognized __attribute__ to the compiler but it is used in stdlib.h. Any idea?

Hi Mun Choy,

This warning message is related to function attributes as some of it may not be supported by the compiler. But this is just a warning, and should not give any problem on your rprogram.

Hi Mun Choi,

I agree with Shahmi. These are compiler related warnings that I have reported to compiler engineers. They don't seem to have any negative effect.

Hi Shahmi, Rahul,

Thanks for your reply. These warnings are all over the place of build messages. I have an interim solution to use "-Wno-attributes" but hopefully this can be addressed without suppressing the attribute warnings.
