OK so WikiHow says "add ./ to the start of the file to run it". So I typed in "./ExeLinux" and the following error occurred:
./ExeLinux: error while loading shared libraries: libGDCpp.so: cannot open shared object file: No such file or directory
I guess this is progress? How do I fix this error? I can see a file called "libGDCpp.so" right there in the directory using 2,339,016 bytes of storage, so IDK why it's not being found.
