前言

        本文主要介绍全志T113-S3平台官方SDK,buildroot文件系统tar不支持.gz文件解压缩的问题以及如何配置buildroot文件系统解决该问题的方法介绍。

一、现象描述

        在buildroot文件系统中,使用tar -xzf UpdateShImage.tgz命令解压UpdateShImage.tgz压缩包报错,tar: invalid option -- 'z',如提示所示,表示tar不支持使用带z参数解压,如下所示:

# tar -xzf UpdateShImage.tgz
tar: invalid option -- 'z'
BusyBox v1.29.3 (2023-08-30 11:23:50 CST) multi-call binary.

Usage: tar c|x|t [-hvokO] [-f TARFILE] [-C DIR] [-T FILE] [-X FILE] [--exclude PATTERN]... [FILE]...

Create, extract, or list files from a tar file

        c       Create
        x       Extract
        t       List
        -f FILE Name of TARFILE ('-' for stdin/out)
        -C DIR  Change to DIR before operation
        -v      Verbose
        -O      Extract to stdout
        -o      Don't restore user:group
        -k      Don't replace existing files
        -h      Follow symlinks
        -T FILE File with names to include
        -X FILE File with glob patterns to exclude
        --exclude PATTERN       Glob pattern to exclude
#

二、解决方案

        进入buildroot编译输出目录,对busybox进行配置,如下步骤所示:

        1、进入buildroot编译输出目录:

cftc@cftc-ubuntu:t113-s3_V1.1-V2.1$ cd out/t113/evb1_auto/longan/buildroot/
cftc@cftc-ubuntu:buildroot$
cftc@cftc-ubuntu:buildroot$
cftc@cftc-ubuntu:buildroot$ pwd
/home/cftc/workspace/QZ/t113-s3_V1.1-V2.1/out/t113/evb1_auto/longan/buildroot
cftc@cftc-ubuntu:buildroot$
cftc@cftc-ubuntu:buildroot$

        2、终端输入busybox配置命令, make busybox-menuconfig,进入Archival Utilities  ---> 

[*] Make tar, rpm, modprobe etc understand .gz data ,按空格键选中 .gz data该项即可,如下图所示:

        3、busybox配置保存。输入make busybox-update-config即可保存配置文件,如下图所示:

cftc@cftc-ubuntu:buildroot$
cftc@cftc-ubuntu:buildroot$
cftc@cftc-ubuntu:buildroot$
cftc@cftc-ubuntu:buildroot$ make busybox-update-config
cp -f /home/cftc/workspace/QZ/t113-s3_V1.1-V2.1/out/t113/evb1_auto/longan/buildroot/build/busybox-1.29.3/.config package/busybox/busybox.config
cftc@cftc-ubuntu:buildroot$
cftc@cftc-ubuntu:buildroot$

三、tar解压缩.gz文件

        使用tar -czf / tar -xzf解压缩文件如下所示:

liubin@CompileServer:~/workspace/UpdateShImage/RA1000$
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$ tar -czf UpdateShImage.tgz UpdateShImage/
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$ ls -l
total 10568
drwxr-xr-x 2 liubin liubin     4096 10月 23 16:14 UpdateShImage
-rw-rw-r-- 1 liubin liubin 10815835 10月 25 23:01 UpdateShImage.tgz
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$ rm -rf UpdateShImage
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$ tar -zxf UpdateShImage.tgz
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$ ls -l
total 10568
drwxr-xr-x 2 liubin liubin     4096 10月 23 16:14 UpdateShImage
-rw-rw-r-- 1 liubin liubin 10815835 10月 25 23:01 UpdateShImage.tgz
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$
liubin@CompileServer:~/workspace/UpdateShImage/RA1000$


总结

   修改之后的固件,tar会多出一个参数z (De)compress using gzip,tar zcvf 或tar cvf都可以压缩,执行tar xvf 或者tar zxvf 都可以解压,不要带z也可以解压缩,可能是config里面有CONFIG_FEATURE_TAR_AUTODETECT=y会自动检测。
