[LLVMdev] llvm compile error

[Stefan Weigert]

dear community,

sorry for posting again a beginner's question but i can't find a solution on 
my own.
i installed all llvm and llvm-gcc4 in a directory 
called "~/programs/llvm/install" in my home folder.
i can build a test c - file as follows: 

~/programs/llvm/install/bin/gcc -v -o test test.c
Using built-in specifications.

this was in german so don't be surprised if you find expressions in english 
that llvm-gcc wouldn't output - it's due to my "guess-translation"

ok that works - fine.

but it doesn't produce .bc files so i add the "-emit-llvm" option:

the '#' aren't there of course - it's just for pointing you to the important 
line :)
