makefile 生成 .gch 文件而不是 .o 文件时出现问题
因此,我正在编写一个程序来测试某些数据结构的效率。我有所有的 .h 文件,并且我制作了一个非常糟糕的 makefile,它可能是错误的,尽管它似乎在某种程度上有效。它不是生成 .o 文件,而是生成 .gch 文件,因此当它尝试访问所有 .o 文件时,找不到它们。这是我的 makefile
prog1: main.o dsexceptions.o BinarySearchTree.o SplayTree.o RedBlackTree.o AvlTree.o
g++ -Wall -g -o prog1 main.o dsexceptions.h.gch BinarySearchTree.h.gch SplayTree.h.gch RedBlackTree.h.gch AvlTree.h.gch
main.o: main.cpp AvlTree.h RedBlackTree.h SplayTree.h BinarySearchTree.h dsexceptions.h
g++ -Wall -g -c main.cpp
#shape.o: shape.cpp shape.h grid.h
# g++ -Wall -g -c shape.cpp
dsexceptions.o: dsexceptions.h
g++ -Wall -g -c dsexceptions.h
BinarySearchTree.o: BinarySearchTree.h dsexceptions.h
g++ -Wall -g -c BinarySearchTree.h
SplayTree.o: SplayTree.h dsexceptions.h
g++ -Wall -g -c SplayTree.h
RedBlackTree.o: RedBlackTree.h dsexceptions.h
g++ -Wall -g -c RedBlackTree.h
AvlTree.o: AvlTree.h dsexceptions.h
g++ -Wall -g -c AvlTree.h
clean:
rm -f main main.exe main.o dsexceptions.o BinarySearchTree.o SplayTree.o RedBlackTree.o AvlTree.o *.gch
So, I'm making a program to test the efficiency of certain data structures. I have all the .h files and I made a very terrible makefile that probably is wrong, although it seems to work up to a point. Instead of making .o files it makes .gch files, so when it tries to acces all the .o files they are not found. This is my makefile
prog1: main.o dsexceptions.o BinarySearchTree.o SplayTree.o RedBlackTree.o AvlTree.o
g++ -Wall -g -o prog1 main.o dsexceptions.h.gch BinarySearchTree.h.gch SplayTree.h.gch RedBlackTree.h.gch AvlTree.h.gch
main.o: main.cpp AvlTree.h RedBlackTree.h SplayTree.h BinarySearchTree.h dsexceptions.h
g++ -Wall -g -c main.cpp
#shape.o: shape.cpp shape.h grid.h
# g++ -Wall -g -c shape.cpp
dsexceptions.o: dsexceptions.h
g++ -Wall -g -c dsexceptions.h
BinarySearchTree.o: BinarySearchTree.h dsexceptions.h
g++ -Wall -g -c BinarySearchTree.h
SplayTree.o: SplayTree.h dsexceptions.h
g++ -Wall -g -c SplayTree.h
RedBlackTree.o: RedBlackTree.h dsexceptions.h
g++ -Wall -g -c RedBlackTree.h
AvlTree.o: AvlTree.h dsexceptions.h
g++ -Wall -g -c AvlTree.h
clean:
rm -f main main.exe main.o dsexceptions.o BinarySearchTree.o SplayTree.o RedBlackTree.o AvlTree.o *.gch

您不想将 .h 文件提供给编译器。仅编译 .cpp 文件,其中应包含您的 .h 文件。 (.gch 文件是预编译头文件。)您的头文件不需要 .o 文件,只需将它们 #include 到 .cpp 文件中即可。
You don't want to feed your .h files to the compiler. Only compile the .cpp file, which should include your .h files. (The .gch files are precompiled headers.) You don't need .o files for your headers, just #include them in your .cpp file.
您已经从 bstpierre 获得了解决方案,但只是为了好玩,这是我的 makefile 版本:
You already have the solution from bstpierre, but just for fun here's my version of your makefile:
为了更好地衡量,这是我的 SConstruct,因为 SCons 好多了:)
您可以在 此处。
And just for good measure, here is my SConstruct, because SCons's so much better :)
