本文介绍如何在Hadoop-hdfs项目的源代码目录中使用cmake生成Makefile，并解决常见配置错误，最终完成libhdfs.a的编译。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

进入hadoop-hdfs-project/hadoop-hdfs/src目录，执行cmake以生成Makefile文件。

如果遇到如下的错误：
~/hadoop-2.7.1-src/hadoop-hdfs-project/hadoop-hdfs/src]$ cmake .
JAVA_HOME=, JAVA_JVM_LIBRARY=/data/jdk/jre/lib/amd64/server/libjvm.so
JAVA_INCLUDE_PATH=/data/jdk/include, JAVA_INCLUDE_PATH2=/data/jdk/include/linux
Located all JNI components successfully.
CMake Error at CMakeLists.txt:84 (MESSAGE):
You must set the CMake variable GENERATED_JAVAH
-- Configuring incomplete, errors occurred!

则指定一下cmake参数即可，如下所示：
cmake -DJAVA_HOME=/data/jdk -DGENERATED_JAVAH=/data/jdk .

然后带参数再次执行cmake：
~/hadoop-2.7.1-src/hadoop-hdfs-project/hadoop-hdfs/src]$ cmake -DJAVA_HOME=/data/jdk -DGENERATED_JAVAH=/data/jdk .

下面的显示表示cmake成功，会在当前目录下生成Makefile文件：
JAVA_HOME=/data/jdk, JAVA_JVM_LIBRARY=/data/jdk/jre/lib/amd64/server/libjvm.so
JAVA_INCLUDE_PATH=/data/jdk/include, JAVA_INCLUDE_PATH2=/data/jdk/include/linux
Located all JNI components successfully.

-- Configuring done

-- Build files have been written to: /data/hadoop-2.7.1-src/hadoop-hdfs-project/hadoop-hdfs/src

接下来就可以执行make来编译生成libhdfs.a了。
