修改使用autoconf創建的makefile

我使用autoconf爲我的應用創建Makefile，該應用使用gtkmm-3.0。 configure腳本正常運行並生成makefile。但是makefile文件提出的目標文件庫，後：修改使用autoconf創建的makefile

g++ -g -O2 -lgtkmm-3.0 -latkmm-1.6 -lgdkmm-3.0 -lgiomm-2.4 -lpangomm-1.4 -lgtk-3 -lglibmm-2.4 -lcairomm-1.0 -lgdk-3 -latk-1.0 -lgio-2.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo-gobject -lpango-1.0 -lcairo -lsigc-2.0 -lgobject-2.0 -lglib-2.0 -o base base-base.o

即給予以下錯誤：

/usr/include/gtkmm-3.0/gtkmm/papersize.h:45: undefined reference to `Glib::ustring::ustring(char const*)' 
/usr/include/gtkmm-3.0/gtkmm/papersize.h:45: undefined reference to `Glib::ustring::~ustring()' 
/usr/include/gtkmm-3.0/gtkmm/papersize.h:46: undefined reference to `Glib::ustring::ustring(char const*)'

/home/shashwat001/Documents/UbuntuApps/gtkmmApps/FirstApp/src/base.cpp:9: undefined reference to `Gtk::Window::~Window()'

但是當我手動運行與目標文件上面的語句庫之前：

g++ -g -O2 -o base base-base.o -lgtkmm-3.0 -latkmm-1.6 -lgdkmm-3.0 -lgiomm-2.4 -lpangomm-1.4 -lgtk-3 -lglibmm-2.4 -lcairomm-1.0 -lgdk-3 -latk-1.0 -lgio-2.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo-gobject -lpango-1.0 -lcairo -lsigc-2.0 -lgobject-2.0 -lglib-2.0

然後沒有錯誤發生。所以問題是庫和對象文件的順序。在autoconf腳本中修改什麼以推送Makefile中的訂單更改？

我的猜測是你把你的庫放到錯誤的變量中。儘管它們看起來像選項（以'-l'開始），庫應該進入'LDLIBS'變量。你可能會把它們放到'LDFLAGS'變量中。 – MadScientist 2014-10-06 22:50:52

你是對的MadScientist。這是問題所在。發佈後我很快就明白了，只是忘了更新它。謝謝... – 2014-10-07 01:03:20

What to modify in autoconf script to push order change in Makefile?

如果你只使用autoconf的（沒有automake的），你需要修改與「在」擴展名，如Makefile.in，然後重新運行「的./configure」文件。

如果您還使用automake而不是Makefile.in，則必須編輯Makefile.am。然後運行autoreconf & & ./configure
