[BUG] "name_of_emulator.so" not found

[LodanZark]

If the network gets disconnect in middle of installation of emulator from the source, leaves the compile files on the directory /home/pi/RetroPie-Setup/temp/build/* which cause the error of "name_of_emulator.so" not found" after retrying the process.

This problem can be fixed by assure the folder /home/pi/RetroPie-Setup/temp/build/ gets clean before the compiling process.

If a build fails it should be cleaned so I need an actual example with a log please. Also you need to include things like what version of retropie-setup you are running.

The log I've got before I manually clean the folder /home/pi/RetroPie-Setup/temp/build/ during the compiling lr-picodrive from source. I'm using the retropie 4.0rc1 script (latest)

I will make a change to workaround this - we used to clean the source directory before every build, but there are other issues with that when developing modules etc. I will come up with something. we do clean after sources function fails, but we don't catch the git errors, so that should be enough to sort it.

[LodanZark]

Thank you very much ;)

[joolswills]

I couldn't actually reproduce any problem though. I interrupted git, and it was fine when retrying

[joolswills]

Maybe you have to interrupt git at a specific point.
