error while loading shared libraries: libQuantLib-0.9.9.so

[pajofego]

Hello,

after updating to Ubuntu 9.10 it was necessary to install the new Quantlib wiht version 0.9.9. With the older version 0.9.7 I got no problems after starting the binary.

My example Makefile shows like this:

   g++ -DHAVE_CONFIG_H -I../cpp/QuantLib-0.9.9/ql  -g -O2 -Wall -c -o gjrgarch.o gjrgarch.cpp
        g++  -g -O2 -Wall -o gjrgarch gjrgarch.o -L/usr/local/lib/ -lQuantLib

The error message after typing ./gjrgarch is:

./gjrgarch: error while loading shared libraries: libQuantLib-0.9.9.so: cannot open shared object file: No such file or directory

How I can fix this problem?

Thanks in advance.

Please try a "ldd ./gjrgarch" to see where the linker expects to find
libQuantLib-0.9.9.so

Where did you install this library? Is there possibly more than one
version of libQuantLib.so installed?

Rgds,

Andreas

libQuantLib.so is a link to libQuantLib-x.x.x.so

try:
$ which libQuantLib.so
you should get
$ /usr/local/lib/libQuantLib.so
then
$ls -l /usr/local/lib/libQuantLib.so
and see what it is pointing to, is this file in your search path?

Before installing Quantlib 0.9.9 an older version were installed. So I've done a make uninstall of Quantlib 0.9.7.

Here the output of ls -l /usr/local/lib/libQuantLib*.*

Hi here the output of your purpose:

nothing -> how I can fix this

ls -l /usr/local/lib/libQuantLib.so gives:
/usr/local/lib/libQuantLib.so -> libQuantLib-0.9.9.so

Could this give you further informations?

I'd try running as:

LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH ./gjrgarch

Best,

Hi,

with your method the program starts without error message. But what is the root cause of my problem? How can I fix it without using LD_LIBRARY_PATH.

Thanks in advance.

OK, so libQuantlibLib-0.9.9.so is in the right directory, but the linker didn't find it (see output of
your ldd). Did you run

$ ldconfig

after creating the new library? This is needed to update the cache used by ld. See man page for ldconfig
for details.

Hope this help.
