ilib_build - utility for shared library management
This tool is used to create shared libraries and to generate a loader file which can be used to dynamically load the shared library into Scilab with addinter
Many examples are provided in examples/interface-tour-so directory.
//Here with give a complete example on adding new primitive to Scilab
//create the procedure files
f1=['extern double fun2();'
'void fun1(x,y)'
'double *x, *y;'
'{*y=fun2(*x)/(*x);}'];
mputl(f1,'fun1.c')
f2=['#include <math.h>'
'double fun2(x)'
'double x;'
'{ return( sin(x+1.));}'];
mputl(f2,'fun2.c');
//creating the interface file
i=['#include ""stack-c.h""'
'extern int fun1 _PARAMS(( double *x, double *y));'
'int intfun1(fname)'
'char * fname;'
'{'
' int m1,n1,l1;'
' CheckRhs(1,1);'
' CheckLhs(1,1);'
' GetRhsVar(1, ""d"", &m1, &n1, &l1);'
' fun1(stk(l1),stk(l1));'
' LhsVar(1) = 1;'
' return 0;'
'}'];
mputl(i,'intfun1.c')
//creating the shared library (a gateway, a Makefile and a loader are
//generated.
files=['fun1.o','fun2.o','intfun1.o'];
ilib_build('foo',['scifun1','intfun1'],files,[]);
// load the shared library
exec loader.sce
//using the new primitive
