Hello,
I am working with a host / target machine setup. The cpu arch is the same on both, x86_64 (athlon64), the only real difference is size, ie. my host has a 80GB HD, my targets have 1GB compact flash disks (need this for mechanical vibration reasons). I have CentOS 3.4-x86_64 fully installed on my host, and my target machines have the same OS just with a much smaller package list.
I am trying to get GCC 3.4.3 compiled into a relatively small footprint (< 200 Mb), so I can use it on my targets. I only want c, c++ and java installed. I downloaded the gcc-core .tar and ran the make and make install on that and successfully installed it on my target machine, taking up approximately 40MB. When I build the core along with c++ and java, my libraries such as libgcj.a come out to be over 100MB! Compared to a 20MB libgcj on my Fedora 3 machines.
I've tried compiling with different explicit options such as: --enable-shared, --disable-static, --with-arch=athlon64, and a whole bunch of others. Nothing I've tried gets the size of the libgcj.a file down, nor the other big libraries. Any help or insight would be greatly appreciatied. Thanks.
