With slibtool it fails.

Where slibtool tries to link with:

-Lolad/plugins/e131/./messages/.libs -lolae131conf
-Lolad/plugins/artnet/./messages/.libs -lolaartnetconf

Where the path to the libraries is wrong.

./plugins/e131/messages/libolae131conf.la
./plugins/artnet/messages/libolaartnetconf.la

Where libolae131conf.la is added to plugins_e131_libolae131_la_LIBADD in plugins/e131/Makefile.mk.

plugins_e131_libolae131_la_LIBADD = \
    olad/plugin_api/libolaserverplugininterface.la \
    plugins/e131/messages/libolae131conf.la \
    libs/acn/libolae131core.la

And libolaartnetconf.la in added to plugins_artnet_libolaartnet_la_LIBADD in plugins/artnet/Makefile.mk.

plugins_artnet_libolaartnet_la_LIBADD = \
    olad/plugin_api/libolaserverplugininterface.la \
    plugins/artnet/libolaartnetnode.la \
    plugins/artnet/messages/libolaartnetconf.la

And both Makefile.mk files are included in plugins/Makefile.mk.

include plugins/espnet/Makefile.mk
include plugins/ftdidmx/Makefile.mk

if !USING_WIN32
include plugins/usbpro/Makefile.mk
include plugins/dmx4linux/Makefile.mk
include plugins/e131/Makefile.mk
include plugins/uartdmx/Makefile.mk
endif

Which is included in the main Makfile.am.

# The includes
# -----------------------------------------------------------------------------

# Since `make install` relinks the libraries, this should be in the order in
# which libraries depend on each other. e.g. common, plugin_api, plugins, server.
include common/Makefile.mk

include debian/Makefile.mk
include doxygen/Makefile.mk
include examples/Makefile.mk
include include/Makefile.mk
include javascript/Makefile.mk
include man/Makefile.mk
include libs/Makefile.mk
include ola/Makefile.mk
# olad/plugin_api/Makefile.mk is included directly due to the order of
# dependencies between them; we need to build olad/plugin_api, then the
# plugins, then olad
include olad/plugin_api/Makefile.mk
include plugins/Makefile.mk
include olad/Makefile.mk
include protoc/Makefile.mk
include python/Makefile.mk
include scripts/Makefile.mk
include tools/Makefile.mk

The way these are being included seem to confuse slibtool, as is already known GNU libtool links directly with the .so files on Linux.

Looking at tmp1 for -lolaartnetconf.

$ find . -type f -name '*tmp1' | xargs grep -- -lolaartnetconf

The issue lied elsewhere and was in fact rather subtle, having to do with the scenario when the dependencies of a/b/libfoo.la were imported in the dependency list of x/libbar.la. The different directory depths of the .la build targets had to be accounted for, an this has been done in commit 62a0071.
