我有通过JNI使用cpp共享库libclient.so的
java程序Client.class.
libclient.so构建为共享并使用cpp共享库libhttp.so.
libclient.so和libhttp.so放在文件夹/ home / client / lib64中
Client.class放在/ home / client / bin中
客户端可以加载库
> System.load和环境变量LD_LIBRARY_PATH
> System.loadLibrary和-Djava.library.path
第一种方式很好.
export LD_LIBRARY_PATH = / home / client / lib64
java -classpath ./bin客户端
secon方式失败了.
java -classpath ./bin -Djava.library.path =./ .. / lib64客户端
java.lang.UnsatisfiedLinkError: /home/client/lib64/libclient.so: libhttp.so: cannot open shared object file: No such file or directory
当我将libhttp.so放入/usr/lib64时,第二种方式可以正常工作.
如果我使用System.loadLibrary,为什么libclient.so在/usr/lib64中寻找libhttp.so？
如何在不将libhttp.so复制到/usr/lib64的情况下修复它？
我的加载代码：
//Try load from -Djava.library.path
boolean found = false;
String lib = "client";
try {
System.loadLibrary(lib);
found = true;
} catch (UnsatisfiedLinkError e) {
e.printStackTrace();
}
//Try load from LD_LIBRARY_PATH
if (!found) {
lib = "libclient.so";
String ld_lib_path = System.getenv("LD_LIBRARY_PATH");
String[] paths = ld_lib_path.split(":");
for(int i=0; i
String p = paths[i];
File x = new File(p, lib);
if (x.exists()) {
System.load(x.getAbsolutePath());
found = true;
break;
}
}
}
附加信息.
如果我用ldd测试libclient.so,那么我看到：libhttp.so =>未找到
如果我设置export LD_LIBRARY_PATH = / home / client / lib64,那么我看到：libhttp.so => /home/client/lib64/libhttp.so
