I believe that this is caused by "not making libs depend on each other as
it should be".
Because the C++ program (libecasound, libkvutils) is being linked,
you need to use g++ to link. I have an impression that it was not a problem when
the C program was only explicitly linked with libecasoundc.
However, I've got an impression that libecasoundc itself is a c++ program,
and the linking needs to be performed using g++.
Like this:
$ libtool c++ ecidoc_example.c ../libecasoundc/libecasoundc.la -o a.out -I.
c++ ecidoc_example.c -o .libs/a.out -I. ../libecasoundc/.libs/libecasoundc.so /home/dancer/DEBIAN/ecasound/cvs/ecasound/sound/ecasound/libecasound/.libs/libecasound.so /home/dancer/DEBIAN/ecasound/cvs/ecasound/sound/ecasound/kvutils/.libs/libkvutils.so -ldl -lm -lpthread -Wl,--rpath -Wl,/usr/local/lib
creating a.out
whereas using cc will result in :
$ libtool cc ecidoc_example.c ../libecasoundc/libecasoundc.la -o a.out -I.
cc ecidoc_example.c -o .libs/a.out -I. ../libecasoundc/.libs/libecasoundc.so /home/dancer/DEBIAN/ecasound/cvs/ecasound/sound/ecasound/libecasound/.libs/libecasound.so /home/dancer/DEBIAN/ecasound/cvs/ecasound/sound/ecasound/kvutils/.libs/libkvutils.so -ldl -lm -lpthread -Wl,--rpath -Wl,/usr/local/lib
