Gcc 如何修复OpenSSL错误“；lib64/libldap.so所需的libssl.so.10可能与libssl.so.1.1“冲突”；在CentOS 7上编译PHP时？

我从一个完全干净的CentOS 7安装开始，没有安装任何东西

从一开始，我就

yum安装了这些RPM：


制造
定位
pcre-devel
外派德维尔酒店
epel释放
libxml2-devel
百日咳
wget
维姆
猞猁
libnghttp2-devel
libnghttp2
nghttp2
libpng-devel
海湾合作委员会*
perl模块加载条件
perl内核
旋度
openssl-devel
马里亚布·德维尔
unixODBC-devel
bzip2-devel
libjpeg-devel
libXpm-devel
freetype-devel
gmp-devel
libmcrypt-devel
httpd-devel

**分辨率编辑**
添加了以下RPM：


塞勒斯·萨斯勒
赛勒斯·萨斯尔·德维尔

我使用下面的相应命令从源代码处编译了OpenSSL 1.1.1、cURL 7.62.0和HTTPD 2.4.38：

OpenSSL
卷曲
HTTPD
到目前为止，一切正常。我能够通过远程机器上的浏览器加载HTML页面。（打开端口80后）

这就是我开始遇到问题的地方

**OPENLDAP编辑（通过编译OPENLDAP解决）**

PHP
弄错
运行<代码>时进行清洁；make

我遇到了以下错误：

制作测试日志

make test

命令返回相同的错误

要停止此警告，请使用系统SSL库，不要自己编译它

---

或者，您必须构建您正在使用的所有库，这些库是针对OpenSSL的链接，您自己（在您的例子中是libldap）

谢谢，这对我很有用。我将使用工作配置脚本更新原始问题，包括配置和安装OpenLDAP库。为了使用最新版本的OpenSSL，我必须用最新版本的已编译OpenSSL编译OpenLDAP。
