I am getting error "userver_tcp: error while loading shared libraries: libulib-1.4.2.so.1 .."

[acrolink]

I am getting this when trying to run /exmples/userver/userver_tcp:

userver_tcp: error while loading shared libraries: libulib-1.4.2.so.1: cannot open shared object file: No such file or directory

Thank you.

Hi,

have made you make install...? how you have configured ULib...?

You must give more information if you want some kind of response...

Thanks @stefanocasazza I did this:

[normal user] ./configure (no special options)
[normal user] ./sudo make [no sudo alerted permission denied errors]
[normal user] ./sudo make install

[stefanocasazza]

in this case you must have the executable userver_tcp installed as /usr/local/bin/userver_tcp, you must run this. If you want play with configuration, the default is located in /usr/local/etc/userver.cfg

The file /usr/local/lib64/libulib-1.4.2.so.1.0.0 is there and the there is in the same directory a symlink named libulib-1.4.2.so.1

[stefanocasazza]

yes, it is correct. What is the question... ?

Despite that the file is there the program returns an error that the file is not there, inspect my original post above..

[stefanocasazza]

you try to run: exmples/userver/userver_tcp or exmples/userver/.libs/userver_tcp

in the last case the error is expected...

I run /usr/local/bin/userver_tcp or the one inside the place where I cloned the rep. '/home/myself/apps/ULib/exmples/userver/userver_tcp'

@stefanocasazza no problem I needed to test run ULib only to compare it to Rails/Unicorn and Nginx/PHP .. not so urgent now.. Thank you for your time.. I will try to run it under Ubuntu and see if the same happens. Currently I was testing under OpenSuse

[stefanocasazza]

there is something weird that I don't understand...

you can do this: sudo vi /etc/ld.so.conf check if present /usr/local/lib64 in the list, if not add it... run: sudo ldconfig -Xv check if in the output is present ..... /usr/local/lib64: libulib-1.4.2.so.1 -> libulib.so ....

then retry to run userver_tcp.

you can also run sudo ldd userver_tcp linux-vdso.so.1 (0x00007fffad976000) libc.so.6 => /lib64/libc.so.6 (0x00007f540147c000) libulib-1.4.2.so.1 => /usr/local/lib64/libulib-1.4.2.so.1 libstdc++.so.6 => /usr/lib/gcc/x86_64-pc-linux-gnu/6.1.0/libstdc++.so.6 (0x00007f54010f4000) /lib64/ld-linux-x86-64.so.2 (0x00007f540182c000) libm.so.6 => /lib64/libm.so.6 (0x00007f5400df0000) libgcc_s.so.1 => /usr/lib/gcc/x86_64-pc-linux-gnu/6.1.0/libgcc_s.so.1 (0x00007f5400bd9000)

@stefanocasazza Thank you very much sudo ldd userver_tcp solved it :+1:

Pretty fast server.. I wonder is it possible to increase the number of worker processes. I have 2 cores and I see that userver starts automatically 2 processes.

[stefanocasazza]

you can set the var PREFORK_CHILD in file configuration /usr/local/etc/userver.cfg...

I had the same problem with Debian linux, but I'm glad I found this issue. The fix which worked for me as well:

cd /usr/local/bin
sudo ldd userver_tcp
