cmake找不到java，但是已经安装 [英] cmake can't find java, but it's installed

问题描述

我试图用cmake构建一个项目。这个项目使用java等。
问题是在代码

  find_package（Java REQUIRED）
  
 
 
 
我收到以下错误：
 错误在/usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108 
（消息）：
 
无法找到Java（缺少：Java_JAVA_EXECUTABLE Java_JAR_EXECUTABLE 
 Java_JAVAC_EXECUTABLE Java_JAVAH_EXECUTABLE Java_JAVADOC_EXECUTABLE ）
 
调用堆栈（最近一次调用）：
 /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:315（_FPHSA_FAILURE_MESSAGE）
 / usr / share / cmake-2.8 / Modules / FindJava.cmake：195（find_package_handle_standard_args）
 CMakeLists.txt：66（find_package）
  
虽然
  which java 
  
输出
  / usr / bin / java 
  
如何来？这个错误的原因是什么？
解决方案
如果你使用linux os，那么你必须设置java home like导出
  JAVA_HOME = / home / aqeel / development / jdk / jdk1.6.0_35 
 export PATH = $ JAVA_HOME / bin：$ PATH 
  
 
I am trying to build a project with cmake. This project is using java among other things.
The problem is that at the code
find_package(Java REQUIRED)
I receive the following error:
CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108
(message):

Could NOT find Java (missing: Java_JAVA_EXECUTABLE Java_JAR_EXECUTABLE
Java_JAVAC_EXECUTABLE Java_JAVAH_EXECUTABLE Java_JAVADOC_EXECUTABLE)

Call Stack (most recent call first):
/usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:315 (_FPHSA_FAILURE_MESSAGE)
/usr/share/cmake-2.8/Modules/FindJava.cmake:195 (find_package_handle_standard_args)
CMakeLists.txt:66 (find_package)
Though 
which java
outputs
/usr/bin/java
How come? What can be the reason of this error?
解决方案
If you are using the linux os then you have to set the java home like export 
JAVA_HOME=/home/aqeel/development/jdk/jdk1.6.0_35   
export PATH=$JAVA_HOME/bin:$PATH
