Hi Guys, cd /home/arion/hadoop-0.20.203.0/src/c++/libhdfs
I made the configure file executable chmod +x configure I run it ./configure I fixed the m32 m64 issue but: gcc -DPACKAGE_NAME=\"libhdfs\" -DPACKAGE_TARNAME=\"libhdfs\" -DPACKAGE_VERSION=\"0.1.0\" "-DPACKAGE_STRING=\"libhdfs 0.1.0\"" -DPACKAGE_BUGREPORT=\"omal...@apache.org\" -DPACKAGE=\"libhdfs\" -DVERSION=\"0.1.0\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_DLFCN_H=1 -DLT_OBJDIR=\".libs/\" "-Dsize_t=unsigned int" -DHAVE_FCNTL_H=1 -Dconst= -Dvolatile= -I. -I. -g -O2 -DOS_LINUX -DDSO_DLFCN -DCPU=\"amd64\" -m64 -I/usr/java/jdk1.6.0_27/include -I/usr/java/jdk1.6.0_27/include/linux -Wall -Wstrict-prototypes -MT hdfs.lo -MD -MP -MF .deps/hdfs.Tpo -c hdfs.c -fPIC -DPIC -o .libs/hdfs.o In file included from /usr/include/bits/types.h:31, from /usr/include/sys/types.h:31, from hdfs.h:22, from hdfs.c:19: /usr/lib/gcc/x86_64-redhat-linux/4.1.2/include/stddef.h:214: error: duplicate ‘unsigned’ /usr/lib/gcc/x86_64-redhat-linux/4.1.2/include/stddef.h:214: error: two or more data types in declaration specifiers hdfs.c: In function ‘errnoFromException’: hdfs.c:125: warning: cast from pointer to integer of different size hdfs.c:125: warning: cast from pointer to integer of different size hdfs.c:125: warning: cast from pointer to integer of different size hdfs.c:125: warning: cast from pointer to integer of different size hdfs.c:125: warning: cast from pointer to integer of different size hdfs.c:125: warning: cast from pointer to integer of different size hdfs.c:131: warning: cast from pointer to integer of different size hdfs.c:131: warning: cast from pointer to integer of different size hdfs.c:131: warning: cast from pointer to integer of different size hdfs.c:131: warning: cast from pointer to integer of different size hdfs.c:131: warning: cast from pointer to integer of different size hdfs.c:131: warning: cast from pointer to integer of different size hdfs.c:137: warning: cast from pointer to integer of different size hdfs.c:137: warning: cast from pointer to integer of different size hdfs.c:137: warning: cast from pointer to integer of different size hdfs.c:137: warning: cast from pointer to integer of different size hdfs.c:137: warning: cast from pointer to integer of different size hdfs.c:137: warning: cast from pointer to integer of different size hdfs.c: In function ‘hdfsConnectAsUser’: hdfs.c:228: warning: cast from pointer to integer of different size hdfs.c:228: warning: cast from pointer to integer of different size hdfs.c:228: warning: cast from pointer to integer of different size hdfs.c:228: warning: cast from pointer to integer of different size hdfs.c:228: warning: cast from pointer to integer of different size hdfs.c:228: warning: cast from pointer to integer of different size hdfs.c: In function ‘hdfsGetHosts’: hdfs.c:1589: warning: cast from pointer to integer of different size hdfs.c:1589: warning: cast from pointer to integer of different size hdfs.c: In function ‘getFileInfoFromStat’: hdfs.c:1802: warning: cast from pointer to integer of different size hdfs.c:1802: warning: cast from pointer to integer of different size hdfs.c:1817: warning: cast from pointer to integer of different size hdfs.c:1817: warning: cast from pointer to integer of different size hdfs.c:1832: warning: cast from pointer to integer of different size hdfs.c:1832: warning: cast from pointer to integer of different size Any suggestions?? ---Nikos Hatzopoulos
