#3354: binaries built with GHC on Mac OS X 10.5 (Leopard) do not work on 10.4
(Tiger)

Os: MacOS X | Architecture: Unknown/Multiple
---------------------+------------------------------------------------------
It seems that binaries (at least those linked with the threaded runtime)
built with GHC on Mac OS X 10.5 do not work on Mac OS X 10.4. The error
message in my case is
{{{
dyld: lazy symbol binding failed: Symbol not found:
_pthread_cond_init$UNIX2003
Referenced from: <the executable>
Expected in: /usr/lib/libSystem.B.dylib
}}}
I believe that the primary reasons for this is that the runtime system is
linked against the 10.5 system libraries, which are not ABI compatible
with the 10.4 system libraries.
Apple provides both 10.4 and 10.5 SDKs with 10.5, along with compiler and
linker options for those who want to build backward-compatible binaries. I
tried to pass these options to the linker, which results in the error
message

It would be nice if GHC on OS X shipped with two version of the runtime
(and the base library?), and had compiler flags to build compatible
binaries. This could be also a problem in the future, with the next OS X
versions.
