Ok I added the try/except block and I think it went into the except part
but I can't see it; the print function does not write into the Visual
Studio output window. So I tried to run the link command (emcc.bat with all
the same parameters) and it still doesn't print the error in the console.
How do I get this print function to write in the console (or VS output
window) ?
