Hi,
Actyally you were right about the typo. When I fixid it, it worked and
i could get 2.8 for the "llvm-config --version" command. So i could
get 2.8 for both the path! What can be the problem then? I will copy
the error that i get to the end of this email, but let me ask some
other questions before copying it:
- How can I make sure that my LLVM is working correctly? I tried to
run the hello-world example. I could get the exe file and execute it,
but when I want to use the .bc file it gives me segmentation fault!

- Can I use llvm-g++ instead of clang? or any other instruction which
was availble when llvm-2.8 was released?
- My ubuntu (wubi) is 64. Could the problem be related to it? or llvm
works perfectly of 64 too?
- the error that i get for installing PinaVM, which can just use
llvm-2.8, is about linking and is as follows:
