makefile中的src_list
时间: 2023-09-15 07:22:43 浏览: 71
在 makefile 中,src_list 是一个变量,用于存储源文件的列表。它通常被用于指定需要编译的源文件。
以下是一个示例 makefile 中的 src_list 的用法:
```
src_list := file1.c file2.c file3.c
# 编译规则
$(target): $(src_list)
gcc -o $@ $^
```
在上面的示例中,src_list 变量包含了三个源文件 file1.c、file2.c 和 file3.c。在编译规则中,$^ 是自动化变量,表示依赖文件列表(即 src_list),$@ 是自动化变量,表示目标文件(即生成的可执行文件)。
通过将需要编译的源文件添加到 src_list 中,并在编译规则中使用该变量,可以方便地管理和编译多个源文件。

makefile SRC
In order to create a Makefile for compiling source files, you can follow these steps:
1. Open a text editor and create a new file named "Makefile" (without any file extension).
2. Inside the Makefile, you need to define the target and dependencies.
3. Specify the compiler and its options, as well as any other necessary variables.
4. Provide the rules for compiling the source files.
Here's an example Makefile for compiling source files named "main.c" and "utils.c":
```makefile
CC = gcc
CFLAGS = -Wall -Wextra
SRC = main.c utils.c
OBJ = $(SRC:.c=.o)
EXEC = myprogram
all: $(EXEC)
$(EXEC): $(OBJ)
$(CC) $(CFLAGS) -o $@ $^
%.o: %.c
$(CC) $(CFLAGS) -c $<
clean:
rm -f $(OBJ) $(EXEC)
```
In this example, the `SRC` variable holds the list of source files, and the `OBJ` variable is used to generate the object file names based on the source file names. The `EXEC` variable specifies the name of the final executable.
The `all` rule is the default target that will be built when you run `make` without specifying a target explicitly. It depends on the `$(EXEC)` target.
The `$(EXEC)` rule specifies that the executable should be built from the object files. The `$@` variable represents the target (the executable), and `$^` represents all the dependencies (the object files).
The `%.o` rule is a pattern rule that compiles each `.c` file into an object file `.o`. The `$<` variable represents the first dependency (the source file).
Finally, the `clean` target is used to remove the object files and the executable.
You can customize this Makefile according to your specific requirements, such as adding additional source files, libraries, or compiler flags.
LOCAL_SRC_FILES 换行
LOCAL_SRC_FILES是一个变量,用于指定要编译的源文件的路径。在GNU Makefile中,可以使用反斜杠(\)来实现换行,以便在多行上指定多个源文件路径。例如:
```
LOCAL_SRC_FILES := \
path/to/file1.cpp \
path/to/file2.cpp \
path/to/file3.cpp
```
这样就可以在多行上指定多个源文件路径,每个路径都以反斜杠(\)结尾。
