Binglin Chang commented on HADOOP-9164:
---------------------------------------
I did some experiments in CMake, turns out cmake has properties VERSION and
SOVERSION:
{code}
SET_TARGET_PROPERTIES(hadoop PROPERTIES
VERSION "3.0.0-snapshot"
SOVERSION "1")
lrwxrwxrwx 1 decster decster 14 2013-07-11 21:05 libhadoop.so ->
libhadoop.so.1
lrwxrwxrwx 1 decster decster 27 2013-07-11 21:05 libhadoop.so.1 ->
libhadoop.so.3.0.0-snapshot
-rwxrwxr-x 1 decster decster 7721 2013-07-11 21:05 libhadoop.so.3.0.0-snapshot
SET_TARGET_PROPERTIES(hadoop PROPERTIES
VERSION "3.0.0-snapshot"
)
lrwxrwxrwx 1 decster decster 27 2013-07-11 22:41 libhadoop.so ->
libhadoop.so.3.0.0-snapshot
-rwxrwxr-x 1 decster decster 7721 2013-07-11 22:41 libhadoop.so.3.0.0-snapshot
SET_TARGET_PROPERTIES(hadoop PROPERTIES
SOVERSION "1")
lrwxrwxrwx 1 decster decster 14 2013-07-11 22:43 libhadoop.so ->
libhadoop.so.1*
-rwxrwxr-x 1 decster decster 7721 2013-07-11 22:43 libhadoop.so.1*
{code}
I am not sure VERSION means "release version",
if we use lib<name>-<release-version>.so.<so_version> format, we need to add
this to library name, like SET_TARGET_PROPERTIES(hadoop-<release-version>
PROPERTIES SOVERSION "<so_version>")
We need some agreement on this, or should I just leave version number change to
another JIRA?
