I managed to get the llvm tool chain compiled on my windows machine
using mingw a couple of weeks ago.
When I tried to run the simple test case provided in the documentation I
ran into a problem of missing object files.
I attempted to compile the simple hello.c hello world application.
Unfortunately I get the following
$ llvm-gcc hello.c -o hello.exe
ld: crt2.o: No such file: No such file or directory
After copying the contents of llvm/Release/bin to llvm/bin I then tried,
$ llvm-gcc -O3 -emit-llvm hello.c -c -o hello.bc
but then after running
$ lli hello.bc
I got.
ERROR: Program used external function '_alloca' which could not be
resolved!
This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.
Something must be wrong with my installation. For one, I note that
there is no crt2.o anywhere in the llvm directory, although such object
files do exist in the mingw installation I used to compile the llvm
tools. I do not know why lli does not work and why it can't find alloca.
