如何在JNI代码中包含cspi / spi.h头文件？

I am trying to include spi.h header file in JNI C code, when the /usr/include/at-spi-1.0/cspi/spi.h file is included in c code I got the following fatal error like " fatal error: cspi/spi.h: No such file or directory ".

我试图在JNI C代码中包含spi.h头文件,当c /代码中包含/usr/include/at-spi-1.0/cspi/spi.h文件时,我得到了以下致命错误,如“致命错误: cspi / spi.h:没有这样的文件或目录“。

for creating '.so' file i used following command like:

用于创建'.so'文件我使用以下命令:

sudo gcc -shared -fPIC -o libHelloJNI.so -I/usr/lib/jvm/java-7-openjdk-amd64/include  -I/usr/lib/jvm/java-7-openjdk-amd64/include/linux  -I/usr/include/at-spi-1.0/cspi  HelloJNI.c

using '-I' I included JNI.h header file successful but when I am trying to include the /usr/include/at-spi-1.0/cspi/spi.h, file I got the fatal error that No such file or directory.

使用'-I'我包含JNI.h头文件成功但当我试图包含/usr/include/at-spi-1.0/cspi/spi.h时,文件我得到致命错误,没有这样的文件或目录。

so please look at following code and give your feedback please!

所以请查看以下代码并提供反馈!

#include<jni.h>
#include<cspi/spi.h>
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include"HelloJNI.h" 

// Implementation of native method sayHello() of HelloJNI class
   JNIEXPORT void JNICALL Java_HelloJNI_sayHello(JNIEnv *env, 
                                      jobject thisObj,jint a) 
   {
       printf("Hello World! %d\n",a);
       return;
   }

   JNIEXPORT void JNICALL JAVA_HelloJNI_initSPI(JNIEnv *env, jclass 
                                               cls)
   {

      int init_error;
      init_error = SPI_init();
      putenv("GTK_MODULES=gail:atk-bridge");
      putenv("GNOME_ACCESSIBILITY=1");

      if(init_error)
      {     
               printf("First time error %d in Initialising 
                      SPI\n",init_error);   
      }
      else
      {
                printf("SPI Initialise successfully");
      }
           SPI_event_main();
           return;
  }

If you specify cspi/spi.h in the #include directive, you don't need cspi in the -I switch.

如果在#include指令中指定cspi / spi.h,则在-I开关中不需要cspi。

Change it to:

将其更改为:

-I/usr/include/at-spi-1.0/
