Unable to run arm-none-eabi-gdb

[bmaupin]

I'm unable to run arm-none-eabi-gdb using the devkitpro/devkitarm image. It appears there are a couple issues:

1. /opt/devkitpro/devkitARM/bin isn't in the path

   $ docker run -it --rm -v "$PWD:/build" devkitpro/devkitarm
   
   # arm-none-eabi-gdb
   bash: arm-none-eabi-gdb: command not found
   
   # find / -name arm-none-eabi-gdb
   /opt/devkitpro/devkitARM/bin/arm-none-eabi-gdb

2. Dependencies are missing:

   # /opt/devkitpro/devkitARM/bin/arm-none-eabi-gdb
   /opt/devkitpro/devkitARM/bin/arm-none-eabi-gdb: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory
   
   # apt install libtinfo5
   ...
   
   # /opt/devkitpro/devkitARM/bin/arm-none-eabi-gdb
   /opt/devkitpro/devkitARM/bin/arm-none-eabi-gdb: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory
   
   # apt -y install libpython2.7
   ...
   
   # /opt/devkitpro/devkitARM/bin/arm-none-eabi-gdb
   (gdb) 

Here's my one-liner workaround for anyone running into this:

docker run -it --rm -v "$PWD:/build" devkitpro/devkitarm sh -c "PATH=/opt/devkitpro/devkitARM/bin:"$PATH"; apt -y install libtinfo5 libpython2.7; arm-none-eabi-gdb"

or:

docker run -it --rm -v "$PWD:/build" devkitpro/devkitarm sh -c "PATH=/opt/devkitpro/devkitARM/bin:"$PATH"; apt -y install libtinfo5 libpython2.7; bash"
