If so, that should be taken care of by the distribution. Of course, a distribution is free to separate the debug info and ship it as a separate package; in that case, it makes sense to distribute stripped binaries. But I think discarding symbols on "make install" is in general a bad idea, especially for long-lived processes such as QEMU where you often have non-reproducible bugs. If symbols are gone, even the simplest bug becomes basically impossible to diagnose from a core dump. The GNU Makefile standards have "make install" and "make install-strip" targets. It would be nice to add "make install-strip" and at the same time flip the default from --enable-strip to --disable-strip. Paolo
