What's up with that? No idea, and the output above seems really weird indeed... What does config.log says about why the check for "whether we are using the GNU C++ compiler" returned "no"? > Does the below patch help? > > Cheers, > Peter > > diff --git a/tests/specflg10.test b/tests/specflg10.test > index efe13f5..ea82e1f 100755 > --- a/tests/specflg10.test > +++ b/tests/specflg10.test > @@ -16,7 +16,7 @@ > > # AM_DEFAULT_SOURCE_EXT > > -required=g++ > +required='gcc g++' Micro-nit: here, I'd also like to see a "FIXME" comments stating that we should modify this to a requirement of generic (non GCC-only) C and C++ compilers at a later moment (e.g., when we merge into master). For the rest, your fix seems good (assuming it truly works ;-) Thanks, Stefano
