和清酒的的libjvm.so已经在/ usr / lib目录aready exisited，我直接让conf文件，在/ etc / ld.so.conf.d / my.conf：

And for sake that the the libjvm.so have aready exisited in the /usr/lib,i directly make a conf file,/etc/ld.so.conf.d/my.conf:

/usr/lib
/usr/local/lib

然后我用命令ldconfig的。
但不幸的是，我仍然遇到同样的问题呢。
任何想法？THX

and then i use command ldconfig. but unfortunately,i still encounter the same problem yet. Any idea?thx

推荐答案

此命令：

gcc -g -Wall `pkg-config --cflags fuse` -Iinclude \
  -I/usr/java/jdk1.6.0_31/include \
  -I/usr/java/jdk1.6.0_31/include/linux `pkg-config --libs fuse`  \
  -L/usr/java/packages/lib/i386 -L/lib -L/usr/lib -ljvm -Lbuild -ljavafuse \
  src/javafuse.c -o javafuse

不正确。链接线事项库和来源的订单，以及您的订单是错误的。

is incorrect. The order of libraries and sources on the link line matters, and your order is wrong.

但是，这不是你的问题是什么现在。你坚持认为 libjvm.so 存在于 / usr / lib目录，但已经表明，没有证据表明它。是什么 ls -l命令/usr/lib/libjvm.so 实际打印？

But that's not what your problem is right now. You insist that libjvm.so exists in /usr/lib, but have shown no evidence that it does. What does ls -l /usr/lib/libjvm.so actually print?

请注意，这将是极不寻常的发现 libjvm.so 在 / usr / lib目录。通常人们会期望找到它在如的/ usr / JAVA /包/ lib中/ I386 /服务器，并且没有搜索的是的目录。

Note that it would be highly unusual to find libjvm.so in /usr/lib. Usually one would expect to find it in e.g. /usr/java/packages/lib/i386/server, and you are not searching that directory.

更新：

好。 libjvm.so 实际上不是在 / usr / lib目录但的/ usr / JAVA /jdk1.6.0_31/jre/lib/i386/server

well. libjvm.so is not actually in the /usr/lib but in /usr/java/jdk1.6.0_31/jre/lib/i386/server

在这种情况下，你需要添加 -L的/ usr / JAVA / jdk1.6.0_31 / JRE / lib中/ I386 /服务器你的链接线。

In that case, you need to add -L/usr/java/jdk1.6.0_31/jre/lib/i386/server to your link line.

和我的gedit conf文件...

And i gedit a conf file ...

显然，这是不够的。
