shared libraries
Hi,
I've got some 3rd party library trying to connect to some libs during runtime. I keep getting an error:
libodbcinst.so.1: cannot open shared object file: No such file or directory.
I'm just wondering how I can figure out what file this library link is looking for - i'm new with linux and don't quite know what the be looking at.
Thanks

hmm I don't understand - inside that same folder I have the following files:
libodbcinst.so
libodbcinst.la
libodbcinst.so.1
libodbcinst.so.1.0.0
is it trying to look for one of those, or something else?
libodbcinst.so
libodbcinst.la
libodbcinst.so.1
libodbcinst.so.1.0.0

Yes, right ;)
You'll have to add that directory to the environment variable LD_LIBRARY_PATH or copy them to some system-library-path (/usr/local/lib e.g., see /etc/ld.so.conf)

They are all already in /usr/local/lib
shouldn't it be able to find whatever it needs in there then?

I depends if /usr/local/lib is in the library search path. Try setting LD_LIBARY_PATH to it to see. It's not a permanent change so setting it will do no harm. When you log out and log back in it will reset. If that doesn't solve it then you probably don't have the correct (version of the) DSOs.

wow - that seemed to work (have been struggling with this for two days).
So I won't really be able to execute that command line statement when I deploy this executable for real - what are my options to embed something in the executable itself to make this work?
Thanks!

Ensure the libs are installed into the correct system library path... usually /usr/lib.
Also, in future if you can't figure out the exact library a program requires try the ldd command...

E.g.
ldd a.out
linux-gate.so.1 => (0xffffe000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x40029000)
libm.so.6 => /lib/tls/libm.so.6 (0x4010e000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x40134000)
libc.so.6 => /lib/tls/libc.so.6 (0x4013f000)
/lib/ld-linux.so.2 (0x40000000)

just put /usr/local/lib in /etc/ld.so.conf and run ldconfig.
That should do.
I wouldn't suggest to put them in /usr/lib, because there should only reside libraries installed by the distribution-packetmanager

The questioner stated, "So I won't really be able to execute that command line statement when I deploy this executable "
This implies he can't "just put /usr/local/lib in /etc/ld.so.conf and run ldconfig"; hence I suggested /usr/lib!
The correct way to do this is to deploy it all as a proper package (e.g. rpm or deb) that will install all the libraries where they need to go (and remove them properly too).

under debian etch it is called "odbcinst1", for example.
