Compiling from source newbie questions

[kaan191]

Hi everyone,

I have just completed compiling from source on my Raspberry Pi 4 model B. The game works (yay!). The openttd executable resides in ~/Games/OpenTTD/build (with the source code in ~/Games/OpenTTD).

I have a few noob questions:
- why is the executable size massive, compared to the downloads on the openttd website? (170MB) I compiled the Release version. I accidentally installed the Debug version before that and that was 250+MB. Is this expected?
- what is the conventional way of putting openttd into the PATH? Do people move the executable into one of the /bin/ folders on the filesystem? (Sorry if this is a stupid question)
- what is the recommended way of "tidying up" after invoking the ``make`` command? Besides the (big) executable, a du -sh of the ~/Games/OpenTTD/build directory reveals a total of 850MB... what can be removed after compiling to save up space? (Also sorry if this is a stupid question)

Thanks and looking forward to learning more (if it isn't obvious, I'm also a bit of a Linux / RPi noob)!

The executable might contain debug symbols (yes, even a release build), which can be removed with the 'strip' utility.

The 'make install' command will copy all the built files to the install directory given during the CMake configuration process. I believe this defaults to /usr/local/games but not entirely sure. It might not be in your default path, but it's definitely a system location that will require root (sudo) access to complete.

The 'make clean' command will remove all built object files and binaries from the build tree.

Thanks! Strip utility did the trick and reduced the executable file size to ~7MB.
