我试图在运行Fedora 14的机器上从Hadoop 0.20.2编译hdfs-fuse扩展。下面是我安装的软件包：
保险丝2.8.5-2.fc14.x86_64
熔断器库，2.8.5-2.fc14.x86_64
保险丝-devel的-2.8.5-2.fc14.x86_64
然后，我按照Hadoop wiki上提供的教程：
http://wiki.apache.org/hadoop/MountableHDFS
总结一下，这里是我使用的步骤：
在进入$ HADOOP_HOME，我使用下面的命令启动libhdfs的编译：
ant编译-C ++ – libhdfs -Dislibhdfs = 1
在第二步中，我将libhdfs库复制到libhdfs文件夹中：
mkdir build / libhdfs
cp build / c ++ / Linux-amd64-64 / lib / * build / libhdfs
我编译fuse_hdfs可执行文件：
ant compile-contrib -Dislibhdfs = 1 -Dfusedfs = 1 -Dlibhdfs-fuse = 1
我的问题是，在最后阶段，我得到以下错误：
[exec] Making all in . [exec] make[1]: Entering directory `/local/opt/hadoop-0.20.2/src/contrib/fuse-dfs' [exec] make[1]: Nothing to be done for `all-am'.

我不认为定义FUSE_HOME会有帮助。 重要的路线是
[exec] /usr/bin/ld: fuse_stat_struct.o: undefined reference to symbol 'ceil@@GLIBC_2.2.5' [exec] /usr/bin/ld: note: 'ceil@@GLIBC_2.2.5' is defined in DSO /lib64/libm.so.6 so try adding it to the linker command line [exec] /lib64/libm.so.6: could not read symbols: Invalid operation [exec] collect2: ld returned 1 exit status
链接器告诉你fuse_stat_struct.c中的符号'ceil'找不到，但它知道它在哪里。 它在libm.so中 – 可能由glibc-devel提供。 也许你需要一个32位版本的libm.so. 我以前没见过这个。
有点search产生这个： http : //lists.fedoraproject.org/pipermail/devel/2010-March/133601.html
作为一个刺戳，试着设置你的LDFLAGS环境variables并重新编译。
ant compile-contrib -Dislibhdfs=1 -Dfusedfs=1 -Dlibhdfs-fuse=1 LDFLAGS=-lm
