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 /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? On 21 May 2018 at 07:46, Guillermo Polito <guillermopolito@gmail.com> wrote:

Hi,
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
