Eli Collins resolved HADOOP-2009.
---------------------------------

Resolution: Won't Fix

LZO was removed
configure script for compiling hadoop native doesn't set lzo lib name correctly
-------------------------------------------------------------------------------

Key: HADOOP-2009
URL: https://issues.apache.org/jira/browse/HADOOP-2009
Project: Hadoop Common
Issue Type: Bug
Components: build
Affects Versions: 0.13.1
Environment: Fedora, amd64
Reporter: Joydeep Sen Sarma
Assignee: Arun C Murthy

Looks like this was already reported (but not resolved on the the list): http://tinyurl.com/2rwu6x
I would like to compile libhadoop on amd64/Fedora and everything seems kosher until I hit this compile error:
[exec] /home/jssarma/fbprojects/hadoop-0.13.1/src/native/src/org/apache/hadoop/io/compress/lzo/LzoCompressor.c:116: error: syntax error before ',' token
the line in question is:
// Load liblzo2.so
liblzo2 = dlopen(HADOOP_LZO_LIBRARY, RTLD_LAZY | RTLD_GLOBAL);
seems like this is being set by:
configure:#define HADOOP_LZO_LIBRARY ${ac_cv_libname_lzo2}
I tried executing the relevant part of configure by hand:
if test -z "`${CC} -o conftest conftest.c -llzo2 2>&1`"; then
if test ! -z "`which objdump`"; then
ac_cv_libname_lzo2="`objdump -p conftest | grep NEEDED | grep lzo2 | sed 's/\W*NEEDED\W*\(.*\)\W*$/\
\"\1\"/'`"
This is not working on my system, since:
objdump -p conftest | grep NEEDED
NEEDED libc.so.6
So that would explain the compile error. Editing the configure script manually for now works.
