IMHO, the FreeBSD base system should provide tools for doing native development - anything beyond that belongs in ports. Given that binutils supports quite an extensive range of targets (of thr order of 100), building them all is impractical and a waste of resources for virtually everyone who uses FreeBSD. >Why can't I use gdb or objdump on FreeBSD/i386 to analyze a core file, or = a=20 >binary from another FreeBSD or even from a non-FreeBSD system?

My reading of contrib/binutils suggests that files for targets not related to FreeBSD are in the exclude/delete list and aren't imported into the FreeBSD repository. >If it really is SO much of a bloat, why do we install gdb, etc. in the fir= st=20 >place? I'm happy with buildworld building a toolchain that supports native development on FreeBSD. I have used FreeBSD for cross-development and I'm happy to manually install a toolchain to support the target I'm developing for. I'd be somewhat concerned if buildworld decided to build a toolchain that supported around several targets for each of around 100 different processors - the vast majority I'd never use. >P.S.

That should be a fairly simple change to arrange for it to build and install the .so as well. --=20 Peter Jeremy --vOmOzSkFvhd7u8Ms Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (FreeBSD) iD8DBQFEpmKb/opHv/APuIcRAp3zAKCvf+DrMn2O43v92eUexyxmYkNdYQCggByu BKgPKkH1wq+wEcGEMNPJ3iQ= =pMUw -----END PGP SIGNATURE----- --vOmOzSkFvhd7u8Ms--
