Problem with GCC 3.4.3 and libgcj


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.

Hey J,

The stripping actually zapped most of it. Took a 100MB library down to about 20MB. I'm curoius why the make/make install sequence doesn't include this step. Must be an option somewhere.

My big search now is for information about the O0g and O2g files which are inside the stdc++.h.gch folder. I found some information indicating they are precompiled headers. But these puppies are 33MB each! Anyone familiar with them? Can I get rid of them somehow with out fubaring the whole thing? Maybe a configuration option?

Thanks again!
