runtime_error

[LiJiangnanBit]

If I uncomment the line

#define SPLINES_DO_NOT_USE_GENERIC_CONTAINER 1

There will be a runtime_error when running the codes on README

terminate called after throwing an instance of 'std::runtime_error' what(): In spline: CubicSpline line: 506 file: src/Splines.hh search(1.1) empty spline Process finished with exit code 134 (interrupted by signal 6: SIGABRT)

Here's my code

#include <iostream>
#include "Splines.hh"
using namespace SplinesLoad ;
using namespace std;
int main() {
    CubicSpline spline ;

    spline . pushBack( 1, 3 ) ;
    spline . pushBack( 2, 1 ) ;
    spline . pushBack( 3, 1 ) ;
    spline . pushBack( 4, 3 ) ;
    spline . build() ;

    cout << spline(1.1) << '\n';     // spline at x = 1.1
    cout << spline.D(1.1) << '\n';   // spline first derivative at x = 1.1
    cout << spline.DD(1.1) << '\n';  // spline second derivative at x = 1.1
    cout << spline.DDD(1.1) << '\n'; // spline third derivative at x = 1.1
    return 0;
}

It works fine if the line is kept commented.

Compiled with clang++ and g++ (version 8) I have no problem.

I suppose that you have compiled the library with

define SPLINES_DO_NOT_USE_GENERIC_CONTAINER 1

commented and then linked with your code compiled with

define SPLINES_DO_NOT_USE_GENERIC_CONTAINER 1

commented. This cannoet be done. In the new version I added a file SplineConfig.hh to be more clear. If you change SplineConfig.hh you must recompile the library.

regards,

Here's my code

include

# include "Splines.hh" using namespace SplinesLoad ; using namespace std; int main () { CubicSpline spline ;

spline . 

pushBack( 1, 3 ) ; spline . pushBack( 2, 1 ) ; spline . pushBack( 3, 1 ) ; spline . pushBack( 4, 3 ) ; spline . build () ;

cout << 

spline(1.1) << '\n'; // spline at x = 1.1

cout << spline.

D(1.1) << '\n'; // spline first derivative at x = 1.1

cout << spline.

DD(1.1) << '\n'; // spline second derivative at x = 1.1

cout << spline.

DDD(1.1) << '\n'; // spline third derivative at x = 1.1

return 0 ; }

It works fine if the line is kept commented.
