Hi Kai, That is right, but under *lib, both 32 bit and 64 bit libraries are installed by default. I want to have just 32 bit libraries under *lib, which is not by default. But yes *lib64 has only 64 bit libraries by default. So my main goal is "not to have any 64bit libraries under *lib". How can I achieve this ?

If it is 'i686-linux-gnu' or something, only the 32-bit libs will be produced, no 64-bit ones... But with something like the 'sparc-solaris2.8' target (telling it being a 32-bit target), both the 32-bit and 64-bit libraries will be produced. So there are problems if running a 32-bit Linux on a 64-bit x86_64 machine and wanting to produce both 32-bit (the default) and 64-bit stuff with the produced GCC... So you shouldn't have any problems with your goal. The default 64- bit libraries will be produced and installed into the '*lib64' and the optional 32-bit libraries into the '*lib'! > -----Original Message----- > >> I have build gcc-v4.1.1 on Linux AMD x86_64.

Building a GCC for Ubuntu's Linux/x86_64 so requires fixes to the GCC defaults!
