#10848 — Dynamic library not found by poretools

Hi,

I try to package porechop[1] but somehow it does not find its dynamic
library.  If I install the resulting package I get:

$ porechop 
could not find cpp_functions.so - please reinstall

Any idea what went wrong here?

Kind regards

       Andreas.

SO_FILE = 'cpp_functions.so'
SO_FILE_FULL = os.path.join(os.path.dirname(os.path.realpath(__file__)), SO_FILE)
if not os.path.isfile(SO_FILE_FULL):
    sys.exit('could not find ' + SO_FILE + ' - please reinstall')

As the executable is in /usr/share/porechop and the lib is in
/usr/lib/x86_64-linux-gnu/porechop, this cannot work. The upstream build
system seems to install them into the same directory.

And wtf is -Wl,-soname,porechop/cpp_functions.so? 

TARGET       = porechop/cpp_functions.so
SONAME       = -soname
$(TARGET): $(OBJECTS)
        $(CXX) $(FLAGS) $(CXXFLAGS) $(LDFLAGS) -Wl,$(SONAME),$(TARGET) -o $(TARGET) $(OBJECTS)

It shouldn't have a soname at all, and especially not THIS ONE.
