如何在 pecl zip 安装操作中跟踪编译错误的原因(使用旧版本 PHP)?

How to trace the reason for compilation errors in a pecl zip install operation (with a legacy version of PHP)?

我不可避免地需要基于PHP 5.4 开发系统。我知道这完全没有安全更新,但这是我现在所拥有的。我希望创建一个 PHP 5.4 Docker 图像用于开发目的。过去,我和我的团队一直在使用基于 Centos 的 PHP 5.6 映像,因为没有可用的 5.4 Centos 映像。

因此,我正在尝试编译 PHP 5.4。经过大量的试验和错误,我已经用最少的编译内扩展编译了 PHP,然后在上面加上了一堆动态可加载的扩展。这意味着我的各种下游项目只需添加正确的 php.ini 扩展命令就可以 select 他们需要的扩展。

这是我的 Dockerfile:

# A custom Docker/PHP build for 5.4
#
# PHP 5.4 is no longer available as a standard image as it is
# well out of support. Centos has been chosen to mirror live
# servers.

除了最后一部分,这是 zip 扩展的 pecl 安装,这完全有效。这是我的控制台输出(来自 Docker 步骤):

这是一个意外的编译错误 - "too many arguments" 感觉库不匹配之类的,但我特别 selected 1.11,这是生产上的扩展版本服务器。会不会是我的 libzip-devel 版本太新了,如果是这样,我可以得到一个更早的版本,并让它在维护版本的 Centos 中工作吗?

我在任何其他扩展上都没有遇到过这个问题,所以也许是运气不好,我在最后一个扩展上遇到了一个诡计问题!

更新

我使用的Centos版本中libzip-devel的原生版本是0.10.1,与生产服务器上报的libzip版本匹配(通过php -i).这是来自 Docker 图片的信息:

我怀疑更改我的 C 编译器是否有帮助,但我当然愿意接受这方面的想法。

我终于解决了这个问题。

为了防止记录不起作用的问题,我首先注意到我有一个补丁级别 PHP 版本差异。我的生产服务器在 5.4.16 上,我正在为 5.4.45 构建。我对此进行了调整,确信它会将正确的代码与其他库一起下载到 link,却发现它没有任何区别。

然后我分析了我必须在 pecl zip 扩展中增加多少版本号才能获得下一个可用的稳定版本,这使我从 zip-1.11.0 升级到 zip-1.12.3。这编译得很好。这并不理想,因为我的生产服务器确实将 zip 1.11.0 与 PHP 5.4.16 混合在一起,但无论如何 - 我们已经使用 5.6 开发了大约一年,尽管我们的目标是在生产中使用 5.4。因此,新图像仍然是一个巨大的胜利,因为它让我们更接近我们的生活环境。
