Building Shared Libraries

You can use mbuild to build C shared libraries on both UNIX and the PC. All

of the

mbuild options that pertain to creating stand-alone applications also

pertain to creating C shared libraries. To create a C shared library, specify one

ormorefileswiththe

.exports extension.The.exports files are text files that

contain the names of the functions to export from the shared library, one per

line. You can i nclude comments in your code by beginning a line (first column)

with

#ora*. mbuild treatstheselinesas commentsand ignoresthem.mbuild

merges multiple .exports files into one master exports list.

For example, given

file1.exports as

times2

times3

and file1.c as

int times2(int x)

{

return 2 * x;

}

int times3(int x)

{

return 3 * x;

}

The command

mbuild file1.c file1.exports

creates a shared library named file1.ext,whereext is the

platform-dependent shared library extension. Forexample, on the PC, itwould

be called

file1.dll. The shared library exports the symbols times2 and

times3.
