[Bug - macOS 15] 🐞 `cp: directory /usr/local/bin does not exist` when running `generic_unix_install.sh`

[jjloneman]

⚠️ Issue

When installing pineflash on macOS 15 (Sequoia), usr/local/bin doesn't exist by default, so I get the following error:

cp: directory /usr/local/bin does not exist

Apparently on newer macOS versions, /usr/local/bin may not exist by default.

Here is the full command output:

$ ./generic_unix_install.sh

chmod: /usr/local/bin/blisp: No such file or directory
cp: directory /usr/local/bin does not exist

On my machine, only /usr/local/lib exists.

🛠️ Solution

To fix this, mkdir -p <dir> should be added before the first cp command in generic_unix_install.sh to create any target directories (and intermediate ones) if needed:

+ $root mkdir -p /usr/local/bin
  $root cp ./blisp /usr/local/bin/blisp
  $root chmod +x /usr/local/bin/blisp
  $root cp ./assets/Pineflash.desktop /usr/share/applications/Pineflash.desktop
  $root cp ./assets/pine64logo.png /usr/share/pixmaps/pine64logo.png
  $root cp ./target/release/pineflash /usr/bin/pineflash
