As in, what features or fixes are required? If not, I think John's question is pertinent. If you're building a binaries to distribute, your best bet might actually be to produce multiple builds targeting specific Linux distributions. Alternately, some specific LSB release (none of which, as far as I can tell, require glibc 2.19+). > Right now I have glib 2.12, > and even on CentOS7-32 bit, what I see is glib 2.14. CentOS 7 is built on glibc 2.17. Also, minor correction: "glib" is the name of a different library than glibc.
