Hello I am trying to compile the hadoop native library on mac os.
My Mac OS X is 10.7.4. My Hadoop is 1.0.3 I have installed the zlib 1.2.7 and lzo 2.0.6 like below: ./configure -shared --prefix=/usr/local/[zlib/lzo] make make install I check the /usr/local/zlib-1.2.7 and /usr/local/lzo-2.0.6, the header files and libraries are there. I change the .bash_profile like below export C_INCLUDE_PATH=$C_INCLUDE_PATH:/usr/local/zlib-1.2.7/include:/usr/local/lzo-2.06/include export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/zlib-1.2.7/lib:/usr/local/lzo-2.06/lib export CFLAGS="-arch x86_64" I switch to hadoop folder and run ant -Dcompile.native=true compile-native I got such information like below [exec] checking stddef.h usability... yes [exec] checking stddef.h presence... yes [exec] checking for stddef.h... yes [exec] checking jni.h usability... yes [exec] checking jni.h presence... yes [exec] checking for jni.h... yes [exec] checking zlib.h usability... yes [exec] checking zlib.h presence... yes [exec] checking for zlib.h... yes [exec] checking Checking for the 'actual' dynamic-library for '-lz'... [exec] configure: error: Can't find either 'objdump' or 'ldd' to compute the dynamic library for '-lz' BUILD FAILED Does anyone meet this issue before? Best Regards, --
