LIBADD不會在Ubuntu上添加一個libtool庫到另一個庫上？

Question

我使用GNU自動工具的一個項目，與Makefile.am一個部分，看起來像這樣：

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 

在這裏，我有一個支持（libtool的）庫，應用程序庫和二進制文件。應用程序庫包含二進制保存main中的所有內容，這是二進制引入的唯一源代碼。

在我的Mac上，這個編譯和鏈接很好，一切都很好。在Ubuntu不過，我得到這個鏈接錯誤：

/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

/usr/bin/ld: myproj/myapp/main.o: undefined reference to symbol 'myproj::mysupport::Application::main(sauce::Modules&, int, char**)' 
/usr/bin/ld: note: 'myproj::mysupport::Application::main(sauce::Modules&, int, char**)' is defined in DSO /home/user/code/local-myproj/debug/myproj/mysupport/.libs/libmysupport.so.0 so try adding it to the linker command line 
/home/user/code/local-myproj/debug/myproj/mysupport/.libs/libmysupport.so.0: could not read symbols: Invalid operation 
collect2: ld returned 1 exit status 

這裏是我的Mac相當於libtool的命令運行：

/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 

一個關鍵的區別似乎是/home/user/code/myproj/debug/myproj/mysupport/.libs/libmysupport.dylib出現在libtool:回聲第二個變體。事實上，如果我在ubuntu命令中使用等價參數，它會成功完成。

缺少的參數對應於Makefile.am中的LIBADD行。所以，這個問題：我做對了嗎？如果是這樣，爲什麼它在OS X而不是Ubuntu上工作？

你確實需要安裝您的支持庫？因爲你可以嘗試在noinst_LTLIBRARIES中聲明它，然後看看是否有效。
