I wanted to mess around with OSSubprocess
(written by Mariano Martinez Peck) from my Pharo 6.1 on my CentOS 7.4.
I searched within the Pharo Project Catalog
and tried to install it.
I got an error:
ioLoadModule(/home/smalltalk/App/pharo6.1-64/pharo-vm/lib/pharo/5.0-201805090836/libgit2.so):

Apparently, some libraries as libcurl-gnutls
are needed by the libgit2.so
.

When I check the dependencies with ldd libgit2.so
:

The issue is apparently with:
libcurl-gnutls.so.4 => not found
libssl.so.1.0.0 => not found
libcrypto.so.1.0.0 => not found
libcurl-gnutls.so.4
library is not apparently shipped with CentOS 7 at all:
We just don't supply anything called libcurl-gnutls* at all. Our curl doesn't use gnutls.
libssl.so.1.0.0
is ancient (same goes for libcrypto.so.1.0.0
). If I check my libssl
:
sudo ls -l /usr/lib64/libssl*
-rwxr-xr-x. 1 root root 341024 May 16 17:20 /usr/lib64/libssl3.so

The CentOS 7 details are:
Static hostname: smalltalk
Icon name: computer-vm
Chassis: vm
Machine ID: beb4030b979d4cdcbf51ec99034121fc
Boot ID: 02ef7d00b2e74489bdb78dead7e2fcf8
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
Now the million dollar question:
How do you deal with such a situation? Is there a reasonable way to recompile the whole Pharo VM
or just the libgit2
library against the newer libraries' versions?
