[Octave-bug-tracker] [bug #50351] install the parallel package failed

[Collin]

Follow-up Comment #2, bug #50351 (project octave):

Thanks for the swift reply. I did what you suggested:
$ export CXX="icpc -std=c++11"
$ echo $CXX
icpc -std=c++11

So, I think c++11 features should be accessible. However, in the octace
propmt, when I installed the parallel package, I got the similar errors as
before:

octave:2> pkg install parallel-3.1.1.tar

pkg: error running the configure script for parallel.

near line 79, column 9

As you can see, -std=c+11 option was on, but it still complained unsupported
C++ features. I was aslo puzzled about "checking whether we are using the GNU
C++ compiler... yes". What I'm using is Intel c++ compiler, but it supposed
the GNU C++ compiler is in use ( ... yes). Appreciate it again for your help.
