ilib_build — utility for shared library management
ilib_build(lib_name,table,files,libs [,makename,ldflags,cflags,fflags,ismex, cc])
a character string, the generic name of the library without path and extension.
2 column string matrix giving the table of pairs 'scilab-name', 'interface name'
string matrix giving source (from Scilab 5.0) or object files needed for shared library creation
string matrix giving extra libraries needed for shred library creation
character string. The path of the Makefile file without extension.
character strings to provide options for the loader, the C compiler and the Fortran compiler.
Internal variable to specify if we are working with mex or not.
Provide the name of the C compiler.
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 SCI/modules/dynamic_link/examples
directory.
Note that a compiler must be available on the system to use this function.
