[Discuss-gnuradio] Some fairy C++ error in gr-filter
Hi list. My 1st post here.
I have a big problem with CMake and some of the generated
files under gr-filter/lib. E.g. here is a snippet from it:
#include "fir_filter_ccc.h"
#include
#include
namespace gr {
namespace filter {
fir_filter_ccc::sptr
fir_filter_ccc::make(int decimation, const std::vector &taps)
{
return gnuradio::get_initial_sptr(new fir_filter_ccc
(decimation, taps)); /// <<< line 40
}
At line 40 my g++ 4.7.2 starts yelling w/o me understanding what it says.
Here is the 1st error (edited):
fir_filter_ccc_impl.cc: In static member function 'static
gr::filter::fir_filter_ccc::
sptr gr::filter::fir_filter_ccc::make(int, const std::vector
>&)':
fir_filter_ccc_impl.cc:40:23: error: cannot allocate an object of abstract type
'gr::filter::fir_filter_ccc'
What's this? Is this because 'FILTER_API' is an dllexport? Or is my
fir_filter_ccc_impl.cc generated incorrectly? What is that file and
fir_filter_ccc.h supposed to look like?
Some info for you: 'g++ -fconserve-space -c -DDEBUG -g -O1 -Wall' ..etc.
Thanks in advance.

OS? GNU Radio version?

No, the error you are showing doesn't really make any sense. But you
also gave us a set of g++ arguments that are not what we would
normally use in GNU Radio. Are you trying to compile this by hand and
not use the cmake/make build system?
