# Gentoo custom Makefile for Bitshuffle C library

# Adapted from GNU Guix:

# Upstream has never specified an soname, so we need to conduct downstream
|
|
# soname versioning. The format of soname is "lib${PN}.so.$(ver_cut 1)".
|
|
# No incompatible ABI changes have been observed yet since version 0.2.4,
|
|
# but just in case the upstream recklessly handles ABI compatibility,
|
|
# please try to test ABI compatibility when updating to a new release,
|
|
# using tools like 'abidiff' in dev-util/libabigail or alike.
