LIBADD не будет добавлять одну библиотеку libtool в другую на ubuntu?

У меня есть проект, использующий GNU autotools, с разделом Makefile.am, который выглядит следующим образом:

lib_LTLIBRARIES += myproj/mysupport/libmysupport.la
myproj_mysupport_libmysupport_la_SOURCES = myproj/mysupport/some_sources.cc

lib_LTLIBRARIES += myproj/myapp/libmyapp.la
myproj_myapp_libmyapp_la_SOURCES = myproj/myapp/app_logic.cc
myproj_myapp_libmyapp_la_LIBADD = myproj/mysupport/libmysupport.la

sbin_PROGRAMS += myproj/myapp/myapp
myproj_myapp_myapp_SOURCES = myproj/myapp/main.cc
myproj_myapp_myapp_LDADD = myproj/myapp/libmyapp.la

Здесь у меня есть библиотека поддержки (libtool), библиотека приложений и двоичный файл. Библиотека приложений содержит все в двоичном файле save main, который является единственным источником, введенным двоичным файлом.

На моем mac это прекрасно компилируется и связывается, все отлично. На Ubuntu, однако, я получаю эту ошибку ссылки:

/bin/bash ./libtool --tag=CXX   --mode=link g++ -Wall -Wextra -Werror -ansi -fprofile-arcs -ftest-coverage --coverage -g -O0 -fprofile-arcs -ftest-coverage  -L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib -L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib -L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib -L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib -L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib  -o myproj/myapp/myapp myproj/myapp/main.o myproj/myapp/libmyapp.la -lgcov -llog4cplus  -lboost_filesystem-mt -lboost_iostreams-mt -lboost_program_options-mt -lboost_system-mt -lboost_thread-mt -lboost_system-mt -pthread

/home/user/code/local-myproj/debug/myproj/mysupport/.libs/libmysupport.so.0: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

Вот эквивалентная команда libtool, выполняемая на мой mac:

/bin/sh ./libtool --tag=CXX   --mode=link g++-4.2 -Wall -Wextra -Werror -ansi -fprofile-arcs -ftest-coverage --coverage -g -O0 -fprofile-arcs -ftest-coverage  -L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib -L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib -L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib -L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib -L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib  -o myproj/myapp/myapp myproj/myapp/main.o myproj/myapp/libmyapp.la -lgcov -llog4cplus -L/usr/local/lib -lintl -R/usr/local/lib -Wl,-framework -Wl,CoreFoundation -lboost_filesystem-mt -lboost_iostreams-mt -lboost_program_options-mt -lboost_system-mt -lboost_thread-mt -lboost_system-mt
libtool: link: g++-4.2 -Wall -Wextra -Werror -ansi -fprofile-arcs -ftest-coverage --coverage -g -O0 -fprofile-arcs -ftest-coverage -Wl,-rpath -Wl,/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib -o myproj/myapp/.libs/myapp myproj/myapp/main.o -Wl,-framework -Wl,CoreFoundation -Wl,-bind_at_load  -L/usr/local/lib myproj/myapp/.libs/libmyapp.dylib /home/user/code/myproj/debug/myproj/mysupport/.libs/libmysupport.dylib -lgcov -llog4cplus -lintl -lboost_filesystem-mt -lboost_iostreams-mt -lboost_program_options-mt -lboost_thread-mt -lboost_system-mt

Ключевым отличием, по-видимому, является появление /home/user/code/myproj/debug/myproj/mysupport/.libs/libmysupport.dylib в libtool: Эхо 2-го варианта. Действительно, если я проскальзываю эквивалентный аргумент в буквальной команде ubuntu, она завершается успешно.

Пропущенный аргумент соответствует строке LIBADD в Makefile.am. Итак, вопрос: Правильно ли я это делаю? Если да, то почему он работает на OS X, а не на Ubuntu?
