The direct URL to download the latest gcc build for our Hackathon is
https://sourceforge.net/projects/softwarefreedom/files/gcc/gcc.tar.xz/download
When I tried to use wget and used this link it downloaded a file named
download even though it was an XZ Compressed file, I still went and
checked by downloading from the browser directly and from the browser it
downloaded the file named gcc.tar.xz
Next steps
1. tar -C /opt Jxvf /path/to/gcc.tar.xz
Please use sudo if you are running this as nonroot, as I encountered
'Permission denied' error as it tries to create a directory inside the
/opt path.
Also, the command is missing a '-', the correct command should be:
$ sudo tar -C /opt -Jxvf ./gcc.tar.xz
Note, the '-' (hyphen) before 'Jxvf', that is needed.
This is the directory structure that gets created under /opt, note that
I have only listed the directories and not the files.
