[llvm-dev] lli can't find vsprintf

[jmiguel hernandez via llvm-dev]

thank you! yes, i guess that is the problem.
unfortunately libcmt doesn't work. could it have another name for lli?

The function missing seems to be part of libcmt since i get a similar error
on linking if i remove the libcmt


D:\llvm\examples\helloworld>lli -load=libcmt hello.bc
Error opening 'libcmt': libcmt: Can't open: The specified module could not
be found.  (0x7E)
  -load request ignored.
LLVM ERROR: Program used external function '___stdio_common_vsprintf' which
could not be resolved!


D:\llvm\examples\helloworld>link hello.obj
