如何使用meson构建C语言项目

4.进入build目录查看构建结果

# 进入build目录查看构建结果
meson_project$ cd build/
meson_project/build$ ls
build.ninja  compile_commands.json  meson-info  meson-logs  meson-private  my_hello  my_hello.p
meson_project/build$ ./my_hello
Hello, Meson!
Hello from helper!
meson_project/build$

5.修改main.c文件,重新构建项目

$ vim main.c
#include <stdio.h>
#include "project.h"
#include "util/helper.h"
int main() {
    printf("Hello, Meson!\n");
    printf("Hello, now you can you use it to build project!\n");
    print_hello_from_helper();
    return 0;
}

回到根目录meson_project重新构建.

meson_project $ meson build --cross-file native-file.txt
Directory already configured.
Just run your build command (e.g. ninja) and Meson will regenerate as necessary.
If ninja fails, run "ninja reconfigure" or "meson --reconfigure"
to force Meson to regenerate.
If build failures persist, run "meson setup --wipe" to rebuild from scratch
using the same options as passed when configuring the build.
To change option values, run "meson configure" instead.
meson_project$ ninja -C build
ninja: Entering directory `build'
[2/2] Linking target my_hello
meson_project$ cd build/
meson_project/build$ ./my_hello
Hello, Meson!
Hello, now you can you use it to build project!
Hello from helper!
meson_project/build$
