问题描述
我试图创建一个有多个文件的makefile。有人可以帮助我吗?
我有的文件是file1.cpp,file2.h和main.cpp
I'm trying to make a makefile with multiple files. Can someone help me?The files I have are file1.cpp, file2.h and main.cpp
file1.cpp包含我的函数。
file2.h包含我的函数的声明。
file1.cpp contains my functions.file2.h contains the declaration of my functions.
main.cpp [在代码中包括file2.h]
file1.cpp [includes file2.h in the code]
main.cpp [includes file2.h in the code]file1.cpp [includes file2.h in the code]
我做了
all: main
gcc -g -Wall -o main main.cpp
的bug,当我尝试编译。我的代码在eclipse上工作得很好。
but it gives me tons of bugs when i try to compile. my codes works perfectly fine on eclipse.
推荐答案
你需要编译所有的.cpp文件不包括在某处)。
这样编译器会知道file1.cpp和main.cpp是一起使用的。
我建议使用g ++代替gcc,因为g ++是特定的c ++编译器,而gcc支持C和C ++。
you'll need to compile all .cpp files that you use (i assume they are not included somewhere).That way the compiler will know that file1.cpp and main.cpp are used together.Also I would suggest using g++ instead of gcc, because g++ is the specific c++ compiler while gcc supports C and C++.
尝试使用:
g++ -g -Wall -o main main.cpp file1.cpp
此外,我建议使用如下的Makefile变量:
Also I would recommend to use Makefile variables like this:
SOURCES = main.cpp file1.cpp
g++ -g -Wall -o main $(SOURCES)
希望这有助于:)
