Good morning all: I think I'm missing something here and just need a bit of clarification... On a stock 64-bit Linux install you end up with /lib and /lib64, /usr/lib and /usr/lib64, etc... I'm the newest gcc for some testing we're doing, using the vendor's configuration options (printed via gcc -v) and when I do a make install, I end up with all the libraries going into $PREFIX/lib. Problem is, the 64-bit libraries are copied first then the 32-bit libraries overwrite the 64-bit libraries. So, when I'm linking I end up with errors. How do I get the 32 and 64 bit libraries into different directories??? Thanks, -b
