Okay, I just did that and MsgSendSmallInt.bc was generated by clang
without errors. Unfortunately Smalltalk still doesn't work for me.
All the tests from the testsuite fail because edlc comes back with the
following error:
Module (null) version 8 doesn't match runtime 8
So apparently the runtime can't be convinced to go on here. I've got
this problem both with libobjc from gcc 4.3.2 and with the one that
shipped with gcc 4.3.3 (on Debian, at least). The error message is a
little misleading, because judging from the code that prints the above
message (the init_check_module_version function in libobjc's init.c)
there is some size mismatch between the size field in the module struct
(which is 16) and the value reported by sizeof(module), which is
32. Since I don't know what to make of that I have attached a backtrace
from the IntegerAdditions test for the perusal of the more knowledgable.
best regards,
Niels
