I'm wondering why I can't compile trinity within a KVM running an 32 bit x86 Gentoo Linux whereas I can compile the same package within a user mode linuc chroot environment image having also a x86 Gentoo.
The only difference seems to be the compiler (gcc-4.8.3 in UML works) whereas within KVM I do have the gcc 4.7.3-r1
n22kvm ~ # emerge trinity
These are the packages that would be merged, in reverse order:

[-] Some header definitions were missing. This is not fatal.
It usually means you're building on an older distribution which doesn't
have header files describing newer kernel features.
Trinity will still compile and run, it just won't use those new features.
Go ahead, and run 'make'
