I'm responsible for administration of a Centos 7 box at my contract job. I'm really more of a developer and not much of a Linux admin, so please bear with me and maybe try to explain this to me like I'm 5.
One of the apps we're working on needed something called pdftk. Unfortunately, a dependency for it is something called libgcj. I read that libgcj is considered deprecated and no longer "ships" with the new Centos 7.
So, I did this:
wget http://mirror.centos.org/centos/6/os/x86_64/Packages/libgcj-4.4.7-11.el6.x86_64.rpm wget https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/pdftk-2.02-1.el6.x86_64.rpm rpm -ivh --nodeps libgcj-4.4.7-11.el6.x86_64.rpm yum install pdftk-2.02-1.el6.x86_64.rpm
And yay pdftk works now. However, I've been reading around and have determined that this was a bad idea. No reasons given for why this was a stupid thing to do. So could anyone shed some light on why I shouldn't have done this? Or perhaps give me some advice or precautions I should take now? I'm afraid to restart the server or install updates until I know this won't break our box.
Thank you in advance.
