icpc 12.1.0, Ubuntu 11.10 (oneiric) and g++

[YannGolanski]

DISCLAIMER: I know that Ubuntu 11.10 (oneiric) is not supported thus why I am not asking officially. However, if anyone had a solution, that would be nice to know.

I am getting the following errors on a simple c++ programme and was wondering if anyone knew of a solution:

[TimP]

Presumably, putting an older g++ (such as 4.4) on PATH might deal with this, if you don't need the newer C++ features. As your popular quotation suggests, look a little way into the past.

[Judith_W_Intel · Accepted solution]

Does specifying -U__GXX_EXPERIMENTAL_CXX0X__ on the command line help?

This should turn off C++0x extensions in the Gnu header files like constexpr which our compiler does not yet support.

Judy

[phopon]

I assume I have the same problem as parent. When using the undefine it works to get rid of the above errors but it disables most of the "supported" c++0x features in icpc. I can reenable them by creating my own headers and defining the parts of the gnu headers that I need not protected by the __GXX tag, but this is rather onerous.

[Judith_W_Intel]

Yes it would have been nice ifthe authors of the Gnu C++ libraryhad conditionalized each C++0x feature in their headers with a different macro so the Intel compiler could have turned on justthe ones we support.

Unfortunately Intel 12.1 does not support some of the C++0xfeatures inGNU 4.6 and later. It is very hard to keep ahead or even stay evenwith the latestGNU versions. Sorry for the inconvenience.

If you use GNU 4.5 or earlier you should be ok.

The switch -U__GXX_EXPERIMENTAL_CXX0X__ worked fine. Thank you.
