我在哪里可以找到适用于Mac OS的jni标头

I'm not asking where I can find it on my own computer, I'm asking where I can get it.

我不是问我在哪里可以在自己的电脑上找到它,我问我在哪里可以得到它。

I've done my google homework, and I didn't find the headers in those paths. There wasn't even a Header folder in my /System/Library/Java/JavaVirtualMachines/... and stuff and I don't have a Developer folder under root.

我已经完成了我的谷歌作业,但我没有在这些路径中找到标题。在我的/ System / Library / Java / JavaVirtualMachines / ...中没有一个Header文件夹和东西,我根本没有Developer文件夹。

Now I'm pretty sure I don't have those headers installed, I checked the MacOS developer website but I only found some broken links.

现在我很确定我没有安装这些标头,我检查了MacOS开发者网站,但我只发现了一些断开的链接。

Shouldn't OpenJDK or SunJDK provide the jni.h header for MacOS somewhere?

OpenJDK或SunJDK不应该在某处为MacOS提供jni.h头吗?

#1

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/JavaVM.framework/Versions/A/Headers/jni.h

But this depends on your environment.

download it and install.

下载并安装。

check java version:

检查java版本:

sodino:~ sodino$ java -version 
java version "1.8.0_45" 
Java(TM) SE Runtime Environment (build 1.8.0_45-b14) 
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

3.find 'java' original path and ‘java_home':

3.find'java'原始路径和'java_home':

sodino:~ sodino$ which java
/usr/bin/java
sodino:~ sodino$ ls -n /usr/bin/java
lrwxr-xr-x  1 0  0  74 Sep 30  2014 /usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java
sodino:~ sodino$/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java_home
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home

get ‘include’ folder and jni.h

获取'include'文件夹和jni.h

now you will find a ‘include’ folder with in ‘/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home’, and open it ‘jni.h’ will be found.

现在你将在'/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home'中找到一个'include'文件夹,然后打开它'jni.h'。

You can use the java_home command to find the correct location. See the Oracle docs.

您可以使用java_home命令查找正确的位置。请参阅Oracle文档。

So for example in your makefile you could have:

例如,在您的makefile中,您可以:

JAVA_HOME:=`/usr/libexec/java_home`
CPPFLAGS:=-I $(JAVA_HOME)/include -I $(JAVA_HOME)/include/darwin

Note that you also need to add $(JAVA_HOME)/include/darwin to the include path so it can find jni_md.h which is the machine-specific part and is included by jni.h

请注意,您还需要将$(JAVA_HOME)/ include / darwin添加到包含路径,以便它可以找到jni_md.h,它是特定于机器的部分,并由jni.h包含。

On Mac OS X 10.8.5, I use "/System/Library/Frameworks/JavaVM.framework/Headers", like:

在Mac OS X 10.8.5上,我使用“/System/Library/Frameworks/JavaVM.framework/Headers”,如:

HelloJNI.o : HelloJNI.c HelloJNI.h
gcc -I"/System/Library/Frameworks/JavaVM.framework/Headers" -fpic -c $< -o $@

BTW, I am using this version of Java:

顺便说一句,我使用的是这个版本的Java:

java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)
