Joydeep Sen Sarma commented on HADOOP-2009:
-------------------------------------------
As I mentioned - i already have a workaround - i edited configure to hard code
the library path.
I don't know how lzo was installed - the system was imaged by IT folks and it
is the way it is. The issue is how to help the next person who hits this error.
Clearly, if grep NEEDED returns empty - there's an error - and either the
script/build needs to stop. Perhaps you might want to just print out an error
from configure and ask them to change the script. or get it off a environment
variable.

> 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.
