Hi,
While installing nurbs 1.3.5 in octave 3.7 compiled from the development
version on debian/sid with gcc-4.6, I got errors with bspeval.cc
bspeval.cc: In function ‘octave_value_list Fbspeval(const
octave_value_list&, int)’:
bspeval.cc:62:71: error: ‘u’ is predetermined ‘shared’ for ‘shared’
bspeval.cc:62:71: error: ‘k’ is predetermined ‘shared’ for ‘shared’
bspeval.cc:62:71: error: ‘c’ is predetermined ‘shared’ for ‘shared’
make: *** [bspeval.oct] Error 1
Compiling directly from the unpacked tarball produced the same error.
Googling a bit seems to suggest that using a -Werror option would help
and indeed compiling went through with "CXXFLAGS=-Werror make" in
nurbs/src directory.
What seems strange is that if -Werror is passed directly as an argument
to mkoctfile, that is,
mkoctfile -Werror bspeval.cc low_level_functions.o,
it fails (with the same error).
My questions are:
* Is the error in compiling bspeval.cc simply due to the increase
stringency of the more recent gcc-4.6? Or is it a bug?
* (Not directly related to nurbs really) Is it a bug in mkoctfile that
-Werror is not respected?
Regards,
ST
