require ExtUtils::Liblist;
ExtUtils::Liblist::ext($potential_libs[, $verbose]);

The input list $potential_libs is in the form -llib1 -llib2 -llib3. Additional library paths may be included in the form -L/another/path, which affects searches for all subsequent libraries. If the Boolean $verbose is specified, verbose output messages are provided. Returns a list of four scalar values:

EXTRALIBS

List of libraries that need to be linked with ld when linking a Perl binary that includes a static extension

LDLOADLIBS

List of static or dynamic libraries that can or must be linked when creating a shared library using ld

LD_RUN_PATH

Colon-separated list of the directories in LDLOADLIBS

BSLOADLIBS

List of libraries that are needed but can be linked in dynamically with the DynaLoader at runtime

The Win32 version (in the standard Perl distribution) is different from the Unix-OS/2 version in several ways:

• -l and -L are not required on the library and path specifications.

• Entries must be libraries, not plain object files.

• If $potential_libs is empty, the return value is also empty.

• The specified libraries can include both static and import libraries.

• LDLOADLIBS and EXTRALIBS are always identical; BSLOADLIBS and LD_RUN_PATH are always empty.
