# Example of how to build and install locally as a shared library

# Usage:
|
|
#
|
|
# $ make -f Makefile.sharedlibrary
|
|
# $ sudo make -f Makefile.sharedlibrary install
|
|
# $ make -f Makefile.sharedlibrary duk # --> example 'duk' linked to shared libduktape

# Soname version must be bumped whenever a binary compatibility change occurs

|

# Duktape 1.4.x, so that it gets automatically bumped for major and minor
|

# releases (potentially binary incompatible), but not for patch releases.
