[SOLVED] How to use 2 versions of same package

[mohittomar13]

Hi.
I'm new to linux and to this forum. I'm learning to program and for that I use KDevelop. Now the problem I'm facing is that KDevelop uses curl14 and cmake to run. Whereas I also play games using epsxe which uses curl13. Now the problem is that currently i can only run one program. If i want to run epsxe then kdevelp will not work and if i want to run kdevelop then epsxe wont work. Now this isn't a big issue as programming is more important and i can leave epsxe. But then this problem could arise in the future for some other software so I need a solution now itself so that I can tackle that problem too.

What i want is that I can make two separate folders and put curl14 and 13 separately in both, then i can point kdevelop to point to one folder and epsxe to other. Is there a way to achieve this? There can be some other solution to this as the one i have mentioned is just a hypothesis.

Please help.

Please excuse my English as English is not my first language.

You need to have epsxe fix their stuff, methinks


aaaand looking at their forum I see this
https://www.ngemu.com/threads/ubuntu...-found.204577/
which leads one here
https://github.com/brandleesee/ePSXe64Ubuntu

libcurl 3 & libcurl 4 now co-exist enabling software like Kodi etc to work simultaneously with ePSXe

The latest installer script has been updated to allow this, in a hacky sort of way as opposed to convincing the emulator's developers to have a new build that will work in a modern distro. I would figure that simply creating a symlink to the current libcurl library would be the easiest and more common method to fix this, but epsxe is closed source, after all....

I have worked around problems like this using LD_LIBRARY_PATH or LD_PRELOAD, but that approach can get tangled up with webs of dependencies. A post at ngemu that claydoh linked to gives details:

A work-around would be to extract libcurl.so.4.5.0 (from libcurl3_7.58.0-2ubuntu2_amd64.deb) into the same folder as epsxe_x64, sym-link or rename it to libcurl.so.4, then run epsxe from a terminal with command:

LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH ./epsxe_x64

If the epsxe executable is not a good place to put the library, it could go somewhere else, so long as LD_LIBRARY_PATH points there. If you don't want to run epsxe from a terminal you can edit the menu item (right-click the K menu, Edit Applications, find the item, and edit the command.)

A more general solution, designed to do this sort of thing, would be a "container", f.ex. docker, but unless you can find a docker already set up for your application it might be a long learning process.

The second link goes to a custom installer script ,that also grabs the library file, and manually puts it somewhere (not installed to the system), then points the emulator to that libcurl .

epsxe on linux has always been horrible since its not open source and they don't seam to release updated linux builds to keep up w/ lib changes.There are several other emulators that are open source you should consider using one of them pcsxr is pretty nice. If your really need epsxe try running the windows version of epsxe via wine.
