Hi. I've been trying to use two different versions of glibc on my system. I have the 2.3.2 and compiled and installed an older version, 2.2.5 under /usr/local/glibc-2.2.5. My objetive is to compile another version of gcc, which will by default use this new glibc. This way, changing glibc's will be just a matter of compiling with one gcc or the other. Is this approach correct? Can anyone help to compile gcc using this new installed glibc? TIA, --- Fabiano Ramos ramosf@xxxxxxxxxxx
