Forge issue: [osx 10.15.7 and ArrayFire v3.7.2 installed from binaries]

[Jason Yin]

Hi, 

I downloaded ArrayFire installer for osx and tried the examples. 

It seems whenever graphics is used, there's an error info (see below). 

Please help. Thanks.

Hello Jason,

Forge is a graphics related direct dependency of ArrayFire. It is shipped along with ArrayFire libraries in the website binaries. One key aspect of ArrayFire graphics functionality is that the required forge dynamic library is loaded at runtime when the first graphics related API call is made. Hence, you see the below error message.

libc++abi.dylib: terminating with uncaught exception of type af::exception: ArrayFire Exception (Failed to load dynamic library. :501):

In function fg_window graphics::ForgeManager::getMainWindow()

In file src/backend/common/graphics_common.cpp:274

Error loading Forge: dlopen(libStatTimer.dylib, 2): image not found

Forge or one of it's dependencies failed to load. Try installing Forge or check if Forge is in the search path.

You need to make the "$AF_PATH/lib" path available via LD_LIBRARY_PATH where the AF_PATH environment variable points to ArrayFire installation. If LD_LIBRARY_PATH doesn't work, try DYLD_LIBRARY_PATH.

That should resolve the problem I think.

Regards,

Pradeep.
