基于xmake的RT_Smart GNU移植minizip记录

由于minizip除了依赖于文件一些操作函数外并不依赖于其他库，所以个人直接编译运行；另外本次移植的是使用的xmake完成移植。

移植记录

1、选择合适的移植库，xmake提供了一些可以跨平台移植的库，这里我选择了minizip来进行移植。

2、编写xmake.lua配置ToolChains并且引入minizip依赖

add_rules("mode.debug", "mode.release")

toolchain("aarch64-linux-musleabi")

set_kind("standalone")

set_sdkdir("$(projectdir)/../../tools/gnu_gcc/aarch64-linux-musleabi_for_x86_64-pc-linux-gnu")

on_load(function(toolchain)

os.setenv("PROJ_DIR", os.projectdir()) --For lua embed build script

toolchain:load_cross_toolchain()

toolchain:set("toolset", "cxx", "aarch64-linux-musleabi-g++")

toolchain:set("toolset", "cc", "aarch64-linux-musleabi-gcc")

-- add flags for aarch64

toolchain:add("cxflags", "-march=armv8-a -D__RTTHREAD__ -Wall -n --static -DHAVE_CCONFIG_H", {force = true})

toolchain:add("ldflags", "-march=armv8-a -D__RTTHREAD__ -Wall -n --static", {force = true})

toolchain:add("ldflags", "-T $(projectdir)/../../linker_scripts/aarch64/link.lds", {force = true})

if not is_config("pkg_searchdirs", "dropbear") then

toolchain:add("ldflags", "-L$(projectdir)/../../sdk/rt-thread/lib/aarch64/cortex-a -Wl,--whole-archive -lrtthread -Wl,--no-whole-archive", {force = true})

end

toolchain:add("includedirs", "$(projectdir)/../../sdk/rt-thread/include", {force = true})

toolchain:add("includedirs", "$(projectdir)/../../", {force = true})

toolchain:add("includedirs", "$(projectdir)", {force = true})

toolchain:add("includedirs", "$(projectdir)/../../sdk/rt-thread/components/dfs", {force = true})

toolchain:add("includedirs", "$(projectdir)/../../sdk/rt-thread/components/drivers", {force = true})

toolchain:add("includedirs", "$(projectdir)/../../sdk/rt-thread/components/finsh", {force = true})

toolchain:add("includedirs", "$(projectdir)/../../sdk/rt-thread/components/net", {force = true})

toolchain:add("linkdirs", "$(projectdir)/../../sdk/rt-thread/lib/aarch64", {force = true})

if is_config("kind", "debug") then

toolchain:add("cxflags", "-g -gdwarf-2", {force = true})

else

toolchain:add("cxflags", "-O2", {force = true})

end

end)

toolchain_end()

add_requires("minizip")

target("minizip")

set_toolchains("aarch64-linux-musleabi")

set_kind("binary")

add_files("src/minizip.c")

add_packages("minizip")

target("miniunz")

set_toolchains("aarch64-linux-musleabi")

set_kind("binary")

add_files("src/miniunz.c")

add_packages("minizip")

target("minizip_test")

set_toolchains("aarch64-linux-musleabi")

set_kind("binary")

add_files("src/main.c")

add_packages("minizip")

配置cconfig.h，这个文件如果用scons会自动生成，但是在xmake工程当中不会自动生成，所以需要自己实现

#ifndef CCONFIG_H__

#define CCONFIG_H__

/* Automatically generated file; DO NOT EDIT. */

/* compiler configure file for RT-Thread in GCC/MUSL */

#define HAVE_SYS_SIGNAL_H 1

#define HAVE_SYS_SELECT_H 1

#define HAVE_PTHREAD_H 1

#define HAVE_FDSET 1

#define HAVE_SIGACTION 1

#define HAVE_SIGEVENT 1

#define HAVE_SIGINFO 1

#define HAVE_SIGVAL 1

#endif

3、编写src/main.c程序，这里我用minizip实现了压缩example.txt到example.zip

  */

  #include "stdio.h"

  #include "zip.h"

  int main()

  {

  // 文件名

  const char *zipfile = "example.zip";

  // 需要压缩的文件

  const char *file = "example.txt";

  zipFile zf = zipOpen(zipfile, APPEND_STATUS_CREATE);

  if(zf == NULL)

  {

  printf("Error creating %s \\n", zipfile);

  return 1;

  }

  // 压缩文件

  int err = zipOpenNewFileInZip(zf, file, NULL, NULL, 0, NULL, 0, NULL, Z_DEFLATED, Z_BEST_COMPRESSION);

  if(err != ZIP_OK)

  {

  printf("Error adding %s to %s \\n", file, zipfile);

  return 1;

  }

  // 读取文件并压缩

  FILE *f = fopen(file, "rb");

  char buf[1024];

  int len;

  while((len = fread(buf, 1, sizeof(buf), f)) > 0)

  {

  zipWriteInFileInZip(zf, buf, len);

  }

  fclose(f);

  zipCloseFileInZip(zf);

  zipClose(zf, NULL);

  printf("Successfully created %s \\n", zipfile);

  return 0;

  }

  4、xmake编译链接生成mininet可执行文件，打包进入 sd.bin

这里我使用的mcopy来实现的（用的是Codespace来写的代码，无root权限，不能使用mount挂载），具体命令为

mcopy -i sd.bin /path/of/the/minizip ::

5、用qemu虚拟机运行即可

运行结果：
