The error said this,
SDL Error
An error occurred while trying to start the application. Please try again and/or reinstall.
Error: dlopen failed: cannot locate symbol "atof" referenced by "libpng16.so"...
If you could know what this means, could you help me fix my problem?
Also this SDL error is appearing on another games.
I don't know SDL, I haven't worked with it since 2014, but I'm pretty sure I know what the error means. Unfortunately I may be unable to help you simply because it's not in my circle of knowledge anymore.
"dlopen failed"
'dlopen' means that a program can, on-the-fly, load extra code it didn't originally need to run (that it now finds it does need) into itself using another file on your system. This is "dynamic loading", which is what the 'dl' in 'dlopen' means, so the .exe file you use to run the game is trying to open another file on your system.
"cannot locate symbol "atof" referenced by "libpng16.so""
'atof', pronounced "A to F" is a piece of code that converts one piece of data to another type of that same data. It exists in a file called 'libpng16.so', a library ('lib-') concerning handling of .png picture files ('-png-'), which is a .so file (basically a DLL, a dynamically-loaded file like I said above).
The reason it's happening on other games is that's how dynamically-loaded files work. They designed to be written once and run by a shit ton of programs. If that file has a bug in the code, all the programs using it will be affected.
