Description

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.
