Description

I have compiled QGIS from source (master, version b6bf12a..90b02ec). Yet, I cannot open QGIS, I am getting the error message: ./qgis: error while loading shared libraries: libqgis_core.so.1.9.0: cannot open shared object file: No such file or directory. The libqgis_core.so.1.9.0 is however in the lib directory /usr/local/qgis1-9/lib.

History

Try

export LD_LIBRARY_PATH=/usr/local/qgis1-9/lib
/usr/local/qgis1-9/bin/qgis

You can make a small bash script to launch it with the above commands it that works for you.

Good temporary solution, thanks

Although the provided solution works, it is a temporary solution i.m.h.o. Also note that in earlier version (both 1.8 and 1.9.90) I do not have the same problems after compiling / installing.

I wouldn't therefore consider this bug closed?

#5 Updated by pvanbosgeo - over 7 years ago

Writing a config file with the path to /usr/local/qgis1-9/lib in /etc/ld.so.conf.d also works:

cd
echo "/usr/local/qgis1-9/lib" > qgis1-9.conf
sudo mv qgis1-9.conf /etc/ld.so.conf.d
cd /etc/ld.so.conf.d
sudo ldconfig

I am still wondering why there was not need to do this before, with other versions. Is this specific to my system?

#6 Updated by Jaka Kranjc over 7 years ago

It's not. The install strips the runtime path (rpath) from the binary, so it expects the library to be in the standard search paths.

#7 Updated by Vaclav Petras about 7 years ago

As stated above LD_LIBRARY_PATH fixes the problem. But since this is not considered as a bug, the solution should be stated somewhere in compile instructions (http://www.qgis.org/api/INSTALL.html and Building_QGIS_with_CMake). Some other solution is mentioned in Building_QGIS_from_Source but this not the solution which most developers want, I think.

The connection to CMAKE_SKIP_RPATH (e.g. #5620) is not clear to me but probably it should be explained.

And now just repeating the solution:

MY_QGIS_PATH=/usr/local/qgis1-9
export LD_LIBRARY_PATH=$MY_QGIS_PATH/lib/
$MY_QGIS_PATH/bin/qgis

maybe it would be worth propose a patch for the documentation?

Too early to be closed.

I have just compiled fresh QGIS master version (1.9.0-Master / 2c59866) on my Fedora 14x64. The LD_LIBRARY_PATH bug is still there. I have put a shell script inside the /etc/profile.d/ with the following line: "LD_LIBRARY_PATH=/usr/local/lib". All the programs (except the new QGIS) accept this configuration.

Now the funny part:

$ qgis
qgis: error while loading shared libraries: libqgis_core.so.1.9.0: cannot open shared object file: No such file or directory
$ echo $LD_LIBRARY_PATH
/usr/local/lib
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH
$ qgis

Now it works!

Any explanations?

you didn't export LD_LIBRARY_PATH, so subprocesses - like qgis - don't see it.
