How do I get blocks/grand central dispatch working in Snow Leopard? It appears that the library is not installed by default: when I try to do #include <dispatch/dispatch.h>, I get a library not found error.
I have tried making the source I found here: http://libdispatch.macosforge.org/ but it generated an error (internal.h:99:27: error: Block_private.h: No such file or directory + others), but I am not even sure if that is the correct source to use. Any pointers on how to get this to work are appreciated.
You shouldn't have to compile anything special to get dispatch.h. In fact, library not found implies that it's a linking error, not anything to do with dispatch.h itself.
For the record, dispatch.h is located at: /Developer/SDKs/MacOSX10.6.sdk/usr/include/dispatch/dispatch.h
Can we see the exact error message? Something doesn't make sense here.
