sonLib for Debian ================= SonLib is originally shipped with a code copy of quicktree. To avoid duplicated code the Debian package links against the separately packaged quicktree. The shared library libsonlib.so already links libquicktree.so.2, so programs that link with -lsonlib get the TreeREP symbols (neighbour_joining_buildtree and friends) automatically and no extra flags are needed. The static archive libsonlib.a still leaves the QuickTree symbols unresolved. When linking against it you need LIBS += -lquicktree and, if your code also includes quicktree headers directly, CFLAGS += -I/usr/include/quicktree The C test suite uses the CuTest framework from libcutest-dev. The copy that upstream keeps in externalTools is not part of the repacked source tarball. -- Andreas Tille Fri, 06 Nov 2026 12:00:00 +0100
