Subject: [dpdk-dev] [PATCH] build: fix soname info in make build
Date: Tue, 10 Dec 2019 18:00:12 +0000 [thread overview]
Message-ID: <20191210180012.871114-1-bruce.richardson@intel.com> (raw)
The soname for each stable ABI version should be just the ABI version major
number without the minor number. Unfortunately both major and minor were
used causing version 20.1 to be incompatible with 20.0.
For make the fix is to separate out the soname passed to the linker from
the final shared library name, and then add an additional symlink to
properly ensure all expected .so.* files are present.
Fixes: cba806e07d6f ("build: change ABI versioning to global")
