Thank you for that. The instructions there are incomplete. It is necessary to add sudo apt-get install libcairo2-dev:i386 to the script.

It's not just Windows users. I have Pharo 6.0 #605.40 running under Linux Ubuntu version 17.10 and the cairo library is definitely installed.
Just starting Pharo is a little concerning: ok@Herbrand:~/Smalltalk$ pharo ioLoadModule(/home/ok/Pharo.d/pharo-vm/lib/pharo/5.0-201707201942/FT2Plugin.so): libfreetype.so.6: cannot open shared object file: No such file or directory ioLoadModule(/home/ok/Pharo.d/pharo-vm/lib/pharo/5.0-201707201942/FT2Plugin.so): libfreetype.so.6: cannot open shared object file: No such file or directory Yet these files exist. /usr/lib/x86_64-linux-gnu/libfreetype.a /usr/lib/x86_64-linux-gnu/libfreetype.so /usr/lib/x86_64-linux-gnu/libfreetype.la <http://libfreetype.la/> /usr/lib/x86_64-linux-gnu/libfreetype.so.6 /usr/lib/x86_64-linux-gnu/libfreetype.so.6.14.0
When I try any Roassal examples, I get Error: cannot locate cairo library. Please check if it is installed ... CairoLibrary(Object) error: CairoLibrary unix32ModuleName Unix32Platform ffiModuleName CairoLibrayr(FFILibrary) moduleName FFICalloutMethodBuilder moduleName
The 32 is the clue. Apparently I'm running a 32-bit Pharo with 64-bit libraries installed. Could this be the problem on Windows?

some Windows users are repeatedly running into Pharo failing to load Cairo library on Windows (see stack screenshot at the bottom).
The problem is that I have no idea how to even start debugging this.
Is there some documentation on how Pharo loads libraries via FFI on Windows that I can start digging into?
Note that the library is definitely present, as this happens only occasionally -- it can be fixed by restarting PC. But I cannot reasonably ask users to restart just because Pharo decided it doesn't feel like loading a library.
Any pointers / docs / ideas appreciated.
You can see the actual code from
