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
          Issue Type: Bug
          Components: build
    Affects Versions: 0.13.1
         Environment: Fedora, amd64
            Reporter: Joydeep Sen Sarma


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.
