Hi Sitvanit,

I tried

CC=gcc44 CXX=g++44 ../llvm/configure and got CC=gcc44: Command not found So the syntax is indeed as wriiten in the help.

actually, no, this just means that you are using a shell that doesn't support this syntax. What shell are you using? Try export CC=gcc44 export CXX=g++44 ../llvm/configure

Ciao, Duncan.

[VAR=VALUE] So I assume configure CC=... is the right syntax. Isn't it? while you might think so, try it the other way round. Also, by doing make VERBOSE=1 you can see which compiler is really being used. Ciao, Duncan. Regard, Sitvanit

Are you sure you are usin gcc44? Don't you need to run CC=gcc44 CXX=g+ +44 ../llvm/configure instead? -- Regards, Konstantin
