libm210.so cannot open

I realize that it's not finding the shared object, but I've downloaded source, "configure && make && sudo make install" on both items.. I don't know how to troubleshoot this.

libtool: install: (cd /usr/local/lib && { ln -s -f libm210.so.0.0.0 libm210.so.0 || { rm -f libm210.so.0 && ln -s libm210.so.0.0.0 libm210.so.0; }; })
libtool: install: (cd /usr/local/lib && { ln -s -f libm210.so.0.0.0 libm210.so || { rm -f libm210.so && ln -s libm210.so.0.0.0 libm210.so; }; })
libtool: install: /usr/bin/install -c .libs/libm210.lai /usr/local/lib/libm210.la
libtool: install: /usr/bin/install -c .libs/libm210.a /usr/local/lib/libm210.a
libtool: install: chmod 644 /usr/local/lib/libm210.a
libtool: install: ranlib /usr/local/lib/libm210.a
libtool: finish: PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/sbin" ldconfig -n /usr/local/lib

Libraries have been installed in:
   /usr/local/lib

Yes, it seems that you are correct. The shared library is not found and that's because in many systems, /usr/local/lib is not in the search path of ld. So there are couple of possibilites, depending on your needs:

1. If you are using Ubuntu/Debian, then the best and easiest way is to add my PPA to to list of package sources of your systems. Then m210 and all of its dependencies will be installed/upgraded just like any other package from official package repositories:

( Of course, just like with any other software repository, you need to trust the provider, in this case me )

  sudo add-apt-repository ppa:tuomasjjrasanen/tjjr

Then you can install m210 simply with:

  sudo apt-get install m210

You will also get update-notifications in the normal manner.

2. Use LD_LIBRARY_PATH environment variable to add /usr/local/lib to ld's search path:

  export LD_LIBRARY_PATH=/usr/local/lib

You can add that line to your ~/.bashrc to automatically add on every new shell session.

3. Add /usr/local/lib to /etc/ld.so.conf. This has ofcourse a system-wide effect.

Btw, the next release of m210 will not depend on separate libm210, but has it bundled in to ease the compilation and installation process.
