I'm having a somewhat disgusting issue on my Gentoo: binaries are unaccountably large.
I'm talking about C programs of my own, so no version related issues whatsoever. The computer is a core i3 with a 32 bit system. Example, for the same program: 10275 B on an atom running Slackware 14.1 (gcc 4.8.2) 5896 B (same, stripped with strip --strip-unneeded) 11675 B on i3, Gentoo, gcc 4.8.3 (with default gcc it was worse) 9704 B stripped 8207 B on *the same i3 box* running LFS (gcc 4.9.1) 5768 B stripped When compiling against dietlibc, the difference is even more shocking (almost double size in Gentoo after stripping). Compiled with: gcc -Os -march=i686 -fomit-frame-pointer -pipe -Wall -pedantic -fdata-sections -ffunction-sections -Wl,--gc-sections -fno-asynchronous-unwind-tables -std=c99 Gentoo: $ gcc -v Using built-in specs.
