Subject: [PATCH] src/Makefile: add ENABLE_SHARED boolean to allow static-only
|
build
|
|
Currently, the libaio builds sytem builds a shared library
|
unconditionally. In some environments, this is not possible or
|
desirable. This commit adds a new Makefile variable, ENABLE_SHARED,
|
which defaults to "1" (i.e shared library enabled) and that allows to
|
override this behavior, and therefore to disable the build and
|
installation of the shared library.
