Re: [Discuss-gnuradio] Error: Template 'vector' undefined.

Could be that the gnuradio reinstall didn't get all of the files in place. Could be that your modifications to the gr-howto do something strange for SWIG purposes. Could be something entirely unexpected. Really hard to know without source code, a logfile, and info about your host computer: OS (name and version), compiler (name and version), GNU Radio (version and how installed). Sorry I can't provide more specific help. - MLD

Reinstalled the workspace for gnuradio. Tried a test on the new workspace with the howto example, but didn't create the Python QA test file. Instead, I directly modified the "square_ff_impl.cc" file. "cmake" command has passed. While doing "make" command, I got: 

Swig source

/usr/include/gnuradio/swig/pmt_swig.i:50: Error: Template 'vector' undefined.

......

In the pmt_swig.i, there are lines:

%include <std_vector.i>

%template(pmt_vector_int8) std::vector<int8_t>;

%template(pmt_vector_uint8) std::vector<uint8_t>;

%template(pmt_vector_int16) std::vector<int16_t>;

%template(pmt_vector_uint16) std::vector<uint16_t>;

%template(pmt_vector_int32) std::vector<int32_t>;

%template(pmt_vector_uint32) std::vector<uint32_t>;

%template(pmt_vector_float) std::vector<float>;

%template(pmt_vector_double) std::vector<double>;

%template(pmt_vector_cfloat) std::vector< std::complex<float> >;

%template(pmt_vector_cdouble) std::vector< std::complex<double> >;

Being able to make it work before in another workspace. It looks like no changes in the swig. Does anybody know where the real problem is?
