I am scripting the creation of chroot jails and part of that automation includes copying various executables and their dependencies into the jail. I am using the following bash line to parse the file paths out of a list of dependencies (for java, for instance):
$ ldd `which java` | grep -o '/[^()]*' /lib/x86_64-linux-gnu/libz.so.1 /lib/x86_64-linux-gnu/libpthread.so.0 /lib/x86_64-linux-gnu/libdl.so.2 /lib/x86_64-linux-gnu/libc.so.6 /lib64/ld-linux-x86-64.so.2
This works great for Node.js and Python, but when I try to execute
java from within the jail, I get an error:
java: error while loading shared libraries: libjli.so: cannot open shared object file: No such file or directory
It turns out that the libjli.so path is missing from the list of dependencies... at least those that
ldd shows us (line 5):
$ ldd `which java` linux-vdso.so.1 => (0x00007ffff7f4d000) libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f7ac3928000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f7ac370c000) libjli.so => not found libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f7ac3507000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f7ac317c000) /lib64/ld-linux-x86-64.so.2 (0x00007f7ac3b48000)
I found the file...
$ find /usr/lib -name libjli.so /usr/lib/jvm/java-6-openjdk-amd64/lib/amd64/jli/libjli.so /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/jli/libjli.so
... but I would like to know why it wasn't listed with
ldd. It is a known dependency apparently, but the path is unknown? Any help is appreciated!
