---------------------------------------
Joydeep,
I don't have access to an amd64-fedora box, could you please try this and let
me know?
{noformat}
$ echo 'int main(int argc, char **argv){return 0;}' > conftest.c
$ gcc -o conftest conftest.c -llzo2
$ objdump -p conftest | grep NEEDED
{noformat}
on my system I get:
{noformat}
$ objdump -p conftest | grep NEEDED
NEEDED liblzo2.so.2
NEEDED libc.so.6
{noformat}
> configure script for compiling hadoop native doesn't set lzo lib name

> 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
> Assignee: Arun C Murthy

> Looks like this was already reported (but not resolved on the the list):

> 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.
