----------------------------------
Summary: src/contrib/fuse-dfs build fails on non-Sun JVM
environments
Key: HADOOP-8333
URL: https://issues.apache.org/jira/browse/HADOOP-8333
Project: Hadoop Common
Issue Type: Bug
Components: build
Affects Versions: 1.0.2
Environment: IBM Java 6
Reporter: Kumar Ravi
src/contrib/fuse-dfs build failure when building in IBM Java 6 environment. The
message on the console when the build aborts is:
[exec] /usr/bin/ld: cannot find -ljvm
[exec] collect2: ld returned 1 exit status
[exec] make[1]: *** [fuse_dfs] Error 1
[exec] make[1]: Leaving directory
`/home/hadoop/branch-1.0_0427/src/contrib/fuse-dfs/src'
[exec] make: *** [all-recursive] Error 1
The reason this seems to be happening is because of the last line in
src/contrib/fuse-dfs/src/Makefile.am
AM_LDFLAGS= -L$(HADOOP_HOME)/build/libhdfs -lhdfs -L$(FUSE_HOME)/lib -lfuse
-L$(JAVA_HOME)/jre/lib/$(OS_ARCH)/server -ljvm
For hadoop to build on IBM Java, this last line should read as follows since
this is where the libjvm library resides
AM_LDFLAGS= -L$(HADOOP_HOME)/build/libhdfs -lhdfs -L$(FUSE_HOME)/lib -lfuse
-L$(JAVA_HOME)/jre/lib/$(OS_ARCH)/j9vm -ljvm
IMO, Changes like the following will need to be made to
src/contrib/fuse-dfs/configure.ac (?) to include changes similar to that in
src/native/ to check for the appropriate JVM and configure the appropriate path
for ljvm.
dnl Check for '-ljvm'
JNI_LDFLAGS=""
if test $JAVA_HOME != ""
then
JNI_LDFLAGS="-L$JAVA_HOME/jre/lib/$OS_ARCH/server"
JVMSOPATH=`find $JAVA_HOME/jre/ -name libjvm.so | head -n 1`
JNI_LDFLAGS="$JNI_LDFLAGS -L`dirname $JVMSOPATH`"
fi
ldflags_bak=$LDFLAGS
LDFLAGS="$LDFLAGS $JNI_LDFLAGS"
AC_CHECK_LIB([jvm], [JNI_GetCreatedJavaVMs])

AC_SUBST([JNI_LDFLAGS])
