I have TOT of llvm and it builds 64-bit without issues on my 64-bit
ubuntu. My question is how to build 32-bit llvm on my 64-bit ubuntu ?
I've not found any configure options to specify that.

Thanks

CC="gcc -m32" CXX="g++ -m32" should do in.

Hi Junjie,

ubuntu. My question is how to build 32-bit llvm on my 64-bit ubuntu ?
I've not found any configure options to specify that.

as well as "gcc -m32" and "g++ -m32" you may want to configure with
--build=i686-pc-linux-gnu

Ciao, Duncan.

make CC="gcc -m32" CXX="g++ -m32" works, but configure ...
--build==i686-pc-linux-gnu does not.

Thanks
