man-db not working
 
Hi,
I'm not that newbie (10+ years using GNU/linux) but i am having a problem where i clearly don't understand the basic functioning of this OS.

Basically, man-db doesn't work.

Code:

$ man
man: error while loading shared libraries: libpipeline.so.1: cannot open shared object file: No such file or directory

A few months ago i installed something that messed with man-db or with libpipeline. I cannot remember what exactly or when.
Since then i tried to fix it by creating links where it is most probable that "man" will search for that particular library. I created links everywhere so man-db can find it. It didn't work (even if that library is there, see next):
Code:

$ ldd /usr/bin/man
        linux-vdso.so.1 (0x7ed95000)
        /usr/lib/arm-linux-gnueabihf/libarmmem.so (0x76f12000)
        libmandb-2.7.5.so => /usr/lib/man-db/libmandb-2.7.5.so (0x76efd000)
        libman-2.7.5.so => /usr/lib/man-db/libman-2.7.5.so (0x76ed2000)
        libgdbm.so.3 => /usr/lib/arm-linux-gnueabihf/libgdbm.so.3 (0x76ea7000)
        libpipeline.so.1 => not found
        libc.so.6 => /lib/arm-linux-gnueabihf/libc.so.6 (0x76d66000)
        /lib/ld-linux-armhf.so.3 (0x54aaa000)
        libpipeline.so.1 => not found
        libz.so.1 => /lib/arm-linux-gnueabihf/libz.so.1 (0x76d3e000)

Here are some files i have and their places:
Code:

I noticed LD_LIBRARY_PATH was not set. I tried setting it manually with no luck.

I also tried to compile man from source.
It does autogen and configure without errors, but fails at "make" instance.
"./configure" works OK
Last line of configure:
Code:

config.status: creating po/Makefile
"make" fails with the following arguments:
Code:

I thought maybe to link the "man" binary with the libpipepline library manually. I don't know how to do that, or if it is even possible.

At this point, i have run out of ideas. Any idea how to solve this? :confused:

Try putting a link in the directory with the library:
Code:

# ln -s /usr/lib/arm-linux-gnueabihf/libpipeline.so.1.4.0 /usr/lib/arm-linux-gnueabihf/libpipeline.so.1

Hi.
It will fail because there's already a file with the same name there:
Code:

$ ls -lth /usr/lib/arm-linux-gnueabihf/libpipeline*
lrwxrwxrwx 1 root root  49 Aug 27 13:28 /usr/lib/arm-linux-gnueabihf/libpipeline.so.1 -> /usr/lib/arm-linux-gnueabihf/libpipeline.so.1.4.0
-rw-r--r-- 1 root root 46K Nov  5  2014 /usr/lib/arm-linux-gnueabihf/libpipeline.so.1.4.0
