qsampler error liblscp.so.6: No such file or directory

[camobrite]

Hi again! So I just reinstalled linuxsampler from source on debian, and I can't start qsampler. I'm getting this output:

bsmith@rayden:~$ qsampler&
[3] 26897
qsampler: error while loading shared libraries: liblscp.so.6: cannot open shared object file: No such file or directory

Any advice? Also, what package do I need for alsa midi support? Thanks!

Just to clarify, my order of install was: libgig, linuxsampler, gigedit, liblscp, qsampler. I don't see why qsampler wouldn't be able to find liblscp.

How did you install them? As .deb packages or did you make "make install"? If you installed liblscp as debian package, then the command "dpkg -L liblscp" should show the following files:

Code: Select all

/.
/usr
/usr/lib
/usr/lib/liblscp.so.6.0.0
/usr/share
/usr/share/doc
/usr/share/doc/liblscp
/usr/share/doc/liblscp/changelog.gz
/usr/share/doc/liblscp/copyright
/usr/share/doc/liblscp/changelog.Debian.gz
/usr/lib/liblscp.so.6

If you installed liblscp directly instead with "make install", then most probably you installed liblscp under /usr/local and your system cannot find the .so file.

Thanks for the reply! I installed linuxsampler using make install. There is a liblscp.so.6 in my /usr/local/lib folder, but not in my /usr/lib folder. There are many such files in /usr/local/lib related to linuxsampler. I could make links to them all in /usr/lib, but I'm afraid that might break things if I uninstall or update linuxsampler. Any advice?

When you compile and install the libs and apps manually with "./configure && make && make install" then by default they are going to be installed under /usr/local to avoid overwriting files of the same libs / apps already installed on your system. You can override the install destination with "./configure --prefix=/usr ... " by the way. However on Debian systems it's always recommended to build debian packages instead of installing things directly. You can find our Debian compilation howto here:

If you don't want to, or don't care about a clean solution, then you can also just edit your /etc/ld.so.conf file and add the path /usr/local/lib to it. Then your system will also search for libraries under /usr/local/lib. But if you insist to do so, make sure you really don't have conflicting versions of libgig, liblscp, liblinuxsampler etc. installed under /usr/lib, otherwise you will still get trouble. But I really discourage this approach, because you can easily end up in chaos.
