Windows 手工生成的Makefile中未定义的引用

我对这个生成文件有问题，我得到一个奇怪的gtkmm错误

CXX=g++
MYSQL_DIR=C:/Program\ Files/MySQL/Connector\ C++\ 1.1/
# -W -Wall -Wextra -Werror
CXXFLAGS=-Wall -std=c++11 $(shell pkg-config --cflags gtkmm-3.0) -I$(MYSQL_DIR)/include -IC:/local/boost_1_72_0
OBJECTS= main.o 
LDLIBS=$(shell pkg-config --libs gtkmm-3.0) -LC:/local/boost_1_72_0/libs -L$(MYSQL_DIR)/lib -LC:/Program\ Files/MySQL/Connector\ C++\ 1.1/lib/opt -lmysqlcppconn -lmysqlcppconn-static

AffittiApp: $(OBJECTS) 
    $(CXX) $(OBJECTS) -o AffittiApp 

main.o: MainWindow.h MainWindow.cpp Affitto.h Affitto.cpp Conguaglio.h Conguaglio.cpp Inquilino.h Inquilino.cpp Stabile.h Stabile.cpp
    $(CXX)  $(CXXFLAGS)  $(LDLIBS) -c main.cpp MainWindow.cpp Affitto.cpp Conguaglio.cpp Inquilino.cpp Stabile.cpp

clean :
    rm -f AffittiApp
    rm *.o
    echo "pulizia completata"

使用这个g++命令，一切都很好

g++ -Wall -std=c++11 Conguaglio.h Conguaglio.cpp Stabile.h Stabile.cpp Inquilino.h Inquilino.cpp Affitto.h Affitto.cpp MainWindow.h MainWindow.cpp main.cpp `pkg-config gtkmm-3.0 --cflags --libs` -IC:/Program\ Files/MySQL/Connector\ C++\ 1.1/include -LC:/Program\ Files/MySQL/Connector\ C++\ 1.1/lib -IC:/local/boost_1_72_0 -LC:/local/boost_1_72_0/libs -LC:/Program\ Files/MySQL/Connector\ C++\ 1.1/lib/opt -lmysqlcppconn -lmysqlcppconn-static

我得到的错误是：

 main.o:main.cpp:(.text+0x35): undefined reference to `Glib::ustring::ustring(char const*)'
    main.o:main.cpp:(.text+0x67): undefined reference to `Gtk::Application::create(int&, char**&, Glib::ustring const&, Gio::ApplicationFlags)'

       make: *** [Makefile:11: AffittiApp] Error 1

我在Makefile中出错了什么？谁能帮帮我吗？谢谢

因此，我发现了问题……我必须在AffittiApp部分中放入$（LDLIBS）。像这样（完整的代码）

我写了这个答案，以防有人有同样的问题。

你引用了

MYSQL\u DIR

，然后添加了

/include

<代码>生成语法不使用引号。此外，您还可以为所有.cpp-s创建一个通用模式规则。谢谢，但我仍然会遇到错误。我用更多的细节编辑了这篇文章
