* What compiler version is this using ? The URL contains both
"5.4.0" as well as "4.4.7".
* The actual error reads "unrecognized command line option
-std=c++11". Given that Boost.uBLAS itself doesn't specify this
flag, I assume it's part of the test runner's configurations.
However, it seems to be used with a compiler version that doesn't
support it (though again, it isn't clear which compiler version we
are actually talking about).
Unfortunately there are quite a large number of columns with
similarly generic errors, i.e. errors more likely to be caused by
invalid set ups, rather than genuine errors in the library
(libraries, as I'm seeing similar errors in other libraries).
What can I do about this ? Ignore the errors ? It would be good
if the metainfo that is displayed with the test runners included a
point of contact (mail address ?) to report such errors.
