SUN_Clink

Compiling and linking a C user function

Syntax

lib = SUN_Clink(names, files, options)

Arguments

names

a string matrix giving the entry point names which are to be linked

files

string matrix giving source files needed for shared library creation

options

a sequence of optional named arguments

lib

the full path of the generated library

Description

This function aims to simplify the compilation and dynamic link of SUNDIALS entrypoints. It is a wrapper to ilib_for_link with the adequate compiler flags and allows to immediately do the dynamic link or copy the DLL and the loading script in the current directory. In that case the default name of the library is defined with the following Scilab code: "lib" + names(1) + getdynlibext()

The options are the following:

loadername,libname,ldflags,cflags,cc

These options have the same meaning as the corresponding formal parameters of ilib_for_link. For example to change the loader name, and the compiler, add the options like this

SUN_Clink(names, files, loader="loader.sce", cc="clang")

load

A boolean value. Set this option to %t if you want to load the library just after compilation. In that case the library and the loading script remain in TMPDIR. If set to %f (the default) the library is not loaded but moved in the current directory with the loading script.

Example

mputl([
"#include <nvector/nvector_serial.h>"
"int sunRhs(realtype t, N_Vector N_VectorY, N_Vector N_VectorYd, void *user_data)"
"{"
"double *y = NV_DATA_S(N_VectorY);"
"double *ydot = NV_DATA_S(N_VectorYd);"
"ydot[0] = y[1];"
"ydot[1] = (1-y[0]*y[0])*y[1]-y[0];"
"return 0;"
"}"
],"code.c");
SUN_Clink("sunRhs", "code.c",load = %t);
[t,y] = cvode("sunRhs",[0 1],[0;2])
