Subject [jira] [Commented] (HADOOP-9215) libhadoop.so doesn't exist (only libhadoop.so.1.0.0)
Date Tue, 15 Jan 2013 18:52:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13554132#comment-13554132

Colin Patrick McCabe commented on HADOOP-9215:
----------------------------------------------

bq. Note I'm using cmake version 2.6-patch 4. Someone on different jira mentioned using 2.8
fixes this issue, I can't easily install that to test.

A newer version of cmake fixes this issue (pretty much any version newer than the ancient
CentOS 5 version).  If you can't upgrade, a workaround is running "mvn compile" twice (yeah,
I know, it sucks.)

I would welcome a patch to fix this (since we still want to support CentOS 5).  The easiest
way to do that is probably to manually make the symlink from libhadoop.so to libhadoop.so.1.0.0
(and so forth) in the CMakeLists.txt script.  This could be put into a library file similar
to how we do with {{JNIFlags.cmake}}.

> Looks like none of the .so files are being built. They all have .so.1.0.0 but no just
.so file.  branch-0.23 works fine but trunk and branch-2 are broke.
> This actually applies to libhadoop.so and libhdfs.so
