Location of SDL2 library

64 posts

Hello,

I am currently using Archlinux and I don't have the SDL2 library loaded into my system.

Yesterday I downloaded the latest Pharo 5 vm and image thanks to the zeroconf scripts.

When I tried to call "OSSDL2Driver hasPlugin" the return was "false" with the following message console :

ioLoadModule(.../pharo-vm/libSDL2DisplayPlugin.so):
libSDL2-2.0.so.0: cannot open shared object file: No such file or directory

The library itself (libSDL2-2.0.so.0) is located in the pharo-vm folder, however it seems that the vm is looking for it somewhere else because after copying the file in /usr/lib32/ the VM was able to find it correctly.

I was wondering : shouldn't the vm only rely on the SDL2 library inside pharo-vm folder ?

Thanks,

Matthieu

IIRC, you get the same error message if a library SDL2-2.0.so relies on cannot be found.

So, assuming the zeroconf has dealth with setting LD_LIBRARY_PATH to include the vm directory, I'd try readelf -d, and check that all (32-bit versions of) the libraries SDL needs are available.

Cheers,

Henry

Hi,

There are some problems with the rpath we are trying to solve… in the mean time, best solution is to affect the LD_LIBRARY_PATH :(

Alright, thanks :)

By the way, on a side note, when downloading the VM for windows, a libcairo-2.dll is provided but when using zeroconf on linux the cairo library is not provided with the VM. Is it intended ?

Because the VM then checks in the system but if you only have 64 bits libraries you need to install 32 bits ones.

yes, this is intended.

in linux you have to install cairo by your own.

I suppose is because we thought it was easier for linux users (and we suppose most of them already have it in their systems).

No idea if we were wrong :)

Alright, thank you :)

I just find the 64bits / 32bits libraries-juggling annoying sometimes :(
