How to add pre-built library to RTSC-ed one ? [message #778546]

Hello,

In the config.bld, we can add C source objects to RTSC-ed library.

var Build = xdc.useModule('xdc.bld.BuildEnvironment');
var Pkg = xdc.useModule('xdc.bld.PackageContents');
 
/* ---- what to build ---- */
 
for each (var targ in Build.targets) {
    Pkg.addLibrary("lib/isqrt_loop", targ).addObjects(["isqrt_loop.c"]);
}

With such a script, the C sources are compiled and then added to RTSC library appropriately.

Now, I would like to know how to add pre-built library to RTSC library.
In this case, how can I add "pre-built.lib" to isqrt_loop.lib ?

Best Regards,
Kawada

Kawada,
each package can supply multiple libraries when being used in a configuration. It's done through the function getLibs, which is implemented in package.xs. In many cases, a package does not implement getLibs because the default implementation can handle the most common case with only one library per package.
Here is a guide for adding getLibs in cases where a package has only pre-built libraries, which is not exactly the same as your case, but the guide should help you write your getLibs.
There is another user guide for writing getLibs, which mostly deals with the cases where your package supports multiple targets and can possibly be invoked for build targets that your package does not support.

Hello Sasha,

Thanks for the quick response ! I got it. Making RTSC package for pre-built lib, and using "require" keyword for it in wrapper package would solve my issue.
