LD 找不到 -l问题的统一解决

/usr/bin/ld: cannot find -l
collect2: error: ld returned 1 exit status

ld -l<xxx> --verbose

如

/usr/bin/ld: cannot find -lhdb

则

可以看到ld在尝试从哪些地方寻找所需的文件

然后就方面通过文件名判断该安装什么包或者做软连接

Error selecting an encoder for stream 0:0

这里使用-vn去掉封面图片，后续再通过其它方式添加

添加封面

封面图片获取

云音乐的FLAC备注中有163 key(Don’t modify):xxx，可以解密得出JSON

  • 算法: AES-128-ECB
  • KEY: #14ljk_!]&0U<'(

从albumPic字段获取封面图片地址

iTunes可识别的封入封面图片

到目前为止，直接使用ffmpeg封入封面，iTunes还是不能识别的

有给视频添加Cover的方式

1
ffmpeg -i input.m4a -i image.jpg -map 0 -map 1 -c copy -disposition:v:1 attached_pic output.m4a

但iTunes是识别不了的

目前使用AtomicParsley封入封面，https://github.com/wez/atomicparsley

1
./AtomicParsley output.m4a --artwork cover.jpg

–overWrite 参数有些编译版本似乎没有，手动重命名吧

Problem

使用composer require 本地GitLab中的项目，会把.git文件夹一块拉进来，从而在commit的时候报子项目问题

Cause

在配置composer repositories时，type使用的是git，则在提取时，等同于git clone，则会连着.git一起clone下来

正确的方法应该是参考 https://docs.gitlab.com/ee/user/packages/composer_repository/

发布时

  1. 在项目中composer init 来生成composer.json
  2. 发布一个release或打一个tag
  3. 通过API发布Composer package，这一步需要access token

成功后会在项目的Package Registry的菜单下看到他

安装时

  1. 在Package Registry点详情进去也会看到相关命令
1
composer config repositories.<group_id> composer https://gitlab.example.com/api/v4/group/<group_id>/-/packages/composer/
  1. 需要设置access token，推荐–global，不然会在项目中留下auth.json，不宜提交
  2. 需要设置gitlab-domains
1
composer config gitlab-domains <你的GitLab地址>
  1. 如果你的GitLab是HTTP，还需要设置"secure-http": false
  2. composer require 你的包

对于Linux命令参数中被误解析成-xxx的参数问题，如

1
2
[root@HBSpy extreme]# rename -mib
rename: invalid option -- 'm'

可以在参数前加–

1
[root@HBSpy extreme]# rename -- -mib .mib extreme-*

参考: https://unix.stackexchange.com/questions/11376/what-does-double-dash-mean

More precisely, a double dash (–) is used in most bash built-in commands and many other commands to signify the end of command options, after which only positional arguments are accepted.
Example use: lets say you want to grep a file for the string -v - normally -v will be considered the option to reverse the matching meaning (only show lines that do not match), but with – you can grep for string -v like this:
grep – -v file

UI Recorder jWebDriver 不支持括号开头的XPath, 如

(//input)[2]

原因在于jWebDriver错误的认为括号开头的是css selector

修改lib/elements.js

$input = shell_exec($cmd = '/usr/bin/python3 ' . APP_PATH . "/library/OpsKG/input_jieba.py $input");

无输出，python其实并没有收到正确的中文输入，exec的中文编码问题

需要先设置exec的环境变量

2
putenv('LC_ALL=en_US.UTF-8');
$input = shell_exec($cmd = '/usr/bin/python3 ' . APP_PATH . "/library/OpsKG/input_jieba.py $input");

或在命令前export LANG=en_US.UTF-8;
