10# Modified for Debian by Junichi Uekawa and Josselin Mouette
11# Major modifications are:
12#    * link libpng explicitly with libz and libm
13#    * $(OLDSO).15 is a symlink rather than a different library
14#    * versioned symbols
15
16# Library name:
17LIBNAME = libpng15
18PNGMAJ = 15

20# Shared library names:
21LIBSO=$(LIBNAME).so
22LIBSOMAJ=$(LIBNAME).so.$(PNGMAJ)
23LIBSOREL=$(LIBSOMAJ).$(RELEASE)
