The /main/source/bin directory is not created

By default, scons will only compile the library files, so you have to tell it to compile the bin directory. You do have the `bin` on the compliation command line, though, so I don’t think that’s the issue.

The build process should be able to create the bin directory if needed. If it can’t, my immediate thought is that there’s something wrong with the permissions on your filesystem. I doubt that a bit, though, as it sounds like you’re able to create the build/ directory and files in there. — At any rate, you can double check that by doing a `mkdir bin/` in the main/source/  directory.

I will note that with output redirection with just `>`, you’re only redirecting the regular output, and are not redirecting the error output. If error messages appear, they’re likely to appear on the terminal where you launched scons, rather than the salida.txt file. Do you happen to know if anything printed there?

The other thing to be aware of is that the compilation process should save progress and restart where it left off. As such, when you’re debugging compilations, it’s often useful to launch your full compile, wait for it to error out, then re-launch the compilation, but this time with `-j1` instead. The re-launch should reach the error much quicker (because compilation skips the things it has already completed), such that it’s feasable to monitor it directly in the terminal. (That is, don’t redirect the output to a file.) — I’d recommend trying that, to see if any error message is apparent.
