how to disable the automatic mapping of std::vector<std::vector<double> > to tuple of tuples in swig python? -


apparently, swig transform automatically std::vector<std::vector<double> > tuple of tuples. want prevent this, , want type kept is. how can achieve it? tried specifying definition type

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

but apparently not work.

two techniques:

  1. %clear typemap type before function processed swig.
  2. declare %template after function processed swig.

example 1

%module x  %begin %{ #pragma warning(disable:4127 4211 4701 4706) %}  %include <std_vector.i> %template(vd) std::vector<double>; %template(vvd) std::vector<std::vector<double> >; %clear std::vector<std::vector<double> >;  %inline %{ #include<vector> std::vector<std::vector<double> > func() {     std::vector<std::vector<double> > temp;     std::vector<double> a;     a.push_back(1.5);     temp.push_back(a);     return temp; } %}

example 2

%module x  %begin %{ #pragma warning(disable:4127 4211 4701 4706) %}  %include <std_vector.i>  %inline %{ #include<vector> std::vector<std::vector<double> > func() {     std::vector<std::vector<double> > temp;     std::vector<double> a;     a.push_back(1.5);     temp.push_back(a);     return temp; }  %}  %template(vd) std::vector<double>; %template(vvd) std::vector<std::vector<double> >;

result (of both)

python 3.3.0 (v3.3.0:bd8afb90ebf2, sep 29 2012, 10:57:17) [msc v.1600 64 bit (amd64)] on win32 type "help", "copyright", "credits" or "license" more information. >>> import x >>> x.func() <x.vvd; proxy of <swig object of type 'std::vector< std::vector< double,std::allocator<double > > > *' @ 0x00000000025f6900> >

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
