修改使用autoconf创建的makefile

我使用autoconf为我的应用创建Makefile，该应用使用gtkmm-3.0。 configure脚本正常运行并生成makefile。但是makefile文件提出的目标文件库，后：修改使用autoconf创建的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

即给予以下错误：

/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()'

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

但是当我手动运行与目标文件上面的语句库之前：

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

然后没有错误发生。所以问题是库和对象文件的顺序。在autoconf脚本中修改什么以推送Makefile中的订单更改？

我的猜测是你把你的库放到错误的变量中。尽管它们看起来像选项（以'-l'开始），库应该进入'LDLIBS'变量。你可能会把它们放到'LDFLAGS'变量中。 – MadScientist 2014-10-06 22:50:52

你是对的MadScientist。这是问题所在。发布后我很快就明白了，只是忘了更新它。谢谢... – 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（没有automake的），你需要修改与 “在” 扩展名，如Makefile.in，然后重新运行 “的./configure” 文件。

如果您还使用automake而不是Makefile.in，则必须编辑Makefile.am。然后运行autoreconf & & ./configure
