Is my install correct ?

Hello,

I have installed llvm-2.0 (on a Linux Fedora 7 distrib) and I get this error during my first use of llvm-gcc :

llvm-gcc -c adder.c
gccas: This tool is deprecated, please use opt
/usr/local/bin/llvm-as: /tmp/ccwPpLIg.s:14,0: /tmp/ccwPpLIg.s:14: error: syntax error, unexpected $undefined, expecting TRIPLE or DATALAYOUT while reading token: 'p'
/usr/local/bin/opt: Invalid bitcode signature

Is my install correct ? Thanks for any advice !

Jean.
