[Octave-bug-tracker] [bug #32444] Range.cc build error: ‘floor’ is not a member of ‘gnulib’

[John W. Eaton]

Follow-up Comment #1, bug #32444 (project octave):

Given what you show for the libgnu/math.h file, the macro


_GL_ _GL_CXXALIAS_SYS (floor, double, (double x)); 


should be expanded, and it should provide gnulib::floor.

Can you please add -save-temps to the command the libtool is executing to
compile Range.cc and attach the resulting .ii file to this bug report?  That
should show whether there is some other math.h file that is being included
instead of libgnu/math.h.

What version of g++ do you have?

Maybe the problem is caused by the bug in GCC that was discussed in the
following thread:
