Smalltalk 在Centos 7.4x上将OSSubprocess添加到my Pharo 6.1时出错

我想在CentOS 7.4上玩我的Pharo 6.1（作者）

我在Pharo项目目录中搜索并尝试安装它

我有一个错误：

ioLoadModule(/home/smalltalk/App/pharo6.1-64/pharo-vm/lib/pharo/5.0-201805090836/libgit2.so):
  libcurl-gnutls.so.4: cannot open shared object file: No such file or directory
tryLoading(/home/smalltalk/App/pharo6.1-64/pharo-vm/lib/pharo/5.0-201805090836/libgit2.so/.libs/,libgit2.so): stat(/home/smalltalk/App/pharo6.1-64/pharo-vm/lib/pharo/5.0-201805090836/libgit2.so/.libs/) Not a directory
ioLoadModule(/home/smalltalk/App/pharo6.1-64/pharo-vm/lib/pharo/5.0-201805090836/libgit2.so):

显然，

libgit2.so

需要一些库，如

libcurl gnutls

ls -la | grep git
-rw-r--r--. 1 smalltalk smalltalk 3019447 May  9 08:55 libgit2.so
-rw-r--r--. 1 smalltalk smalltalk 3019447 May  9 08:55 libgit2.so.0.25.1
-rw-r--r--. 1 smalltalk smalltalk 3019447 May  9 08:55 libgit2.so.25
[smalltalk@smalltalk 5.0-201805090836]$ pwd
/home/smalltalk/App/pharo6.1-64/pharo-vm/lib/pharo/5.0-201805090836

当我用ldd libgit2.so检查依赖项时：

ldd: warning: you do not have execution permission for `./libgit2.so'

问题显然在于：

    libcurl-gnutls.so.4 => not found
    libssl.so.1.0.0 => not found
    libcrypto.so.1.0.0 => not found

libcurl gnutls.so.4

库根本不随CentOS 7提供：

我们根本不提供任何叫做libcurl gnutls*的东西。我们的curl不使用gnutls

libssl.so.1.0.0

很古老（libcrypto.so.1.0.0也是如此）。如果我检查我的

libssl

：

sudo ls -l /usr/lib64/libssl*
-rwxr-xr-x. 1 root root 341024 May 16 17:20 /usr/lib64/libssl3.so

CentOS 7的详细信息如下：

           Chassis: vm

    Virtualization: kvm   Operating System: CentOS Linux 7 (Core)
       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 3.10.0-693.17.1.el7.x86_64
      Architecture: x86-64

现在是百万美元问题：

---

你如何处理这种情况？是否有一种合理的方法来重新编译整个

Pharo VM

，或者仅针对较新的库版本重新编译库？

这似乎与此处提出的一个问题有关：

线程中建议的解决方案，也是对我有效的解决方案，是创建一个符号链接：

ln -s /usr/lib64/libcurl.so.4 /usr/lib64/libcurl-gnutls.so.4

有人玩过吗？等我回来再试试。
