Could not install libpng12-dev

ElrasM

Hi again,

after my new installation of retropie https://retropie.org.uk/forum/topic/25242/unable-to-scrape-unable-to-update almost all seems to work pretty fine.

The only error so far appears when I try to install EasyRPG Player from the experimental packages (RetroPie Extra).
It says "could not install package(s): libpng12-dev"

In the past I have created some games with the RPG Maker 2003 myself, so it bothers me that its not working.

Retropie is up to date and scripts are updated as far as I know.

I read some other posts about problems with libpng12 but could't find a solution for the installation.

So, I ask for your help hopefully a last time.
Thank you very much.

The RetroPie Extra repository has been abandoned for about 2 years and it's not updated. Modify the install script and replace the libpng12-dev dependency with libpng-dev (here), then try to install again EasyRPG Player.

You are truely a hero!
Your solution works very well. I have tested the easyrpg player with my homemade RPG and it works, as far as I have played, without any differences compered to the windows pc version.

Thanks a lot!

@mitu I know that this is quite old, but I came upon it while searching for a solution to the same problem, but with one more issue--in addition to libpng12-dev, I'm also getting an error that it can't install libpixman-1-dev. Is there something I should replace that with as well on the same line? Thanks so much!

@OpossumQueen Without any context (distro/platform/package) I can't offer any advice. Why din't you start a separate topic instead of necro-bumping an old topic and add the info requested in https://retropie.org.uk/forum/topic/3/read-this-first to your question ?
