Debug binaries are also larger: 1300MB - debug binary with 4.5.2 59MB - debug build stripped 850MB - debug build with 4.4.3 180MB - release with 4.4.3 1200MB - release with 4.5.2 45MB - strings of release with 4.5.2 60MB - stripped release with 4.5.2 > By the way, years ago, when I used GNAT 95, Professor Michael Feldman said that GNAT's linker would include in the binary each program from every library the Ada 95 program needed. If you told the machine to optimize the binary, it only deleted the extra routines from the binary. I'm not using ADA. It's C++ with heave use of meta programming. The actual code the program needs to run isn't an issue. It's the debug information. I did some playing with the different gcc flags for compiling a single .o 218M -g2 94M -g1 20M -g0 179M -femit-struct-debug-baseonly 218M -femit-struct-debug-reduced 218M -feliminate-dwarf2-dups 179M -femit-struct-debug-detailed=none 218M -fvar-tracking-assignments-toggle 218M -feliminate-unused-debug-types 173M -gstrict-dwarf 218M -ggdb 218M -feliminate-unused-debug-symbols 294M -gdwarf-version=4 (without -g) 216M -gdwarf-3 (without -g) So it seems to be something in g2, but not in g1. Is there anything else I can turn off?
