saw this section: # Decide level of UFS support. BOOT2_UFS?= UFS1_AND_UFS2 #BOOT2_UFS?= UFS2_ONLY #BOOT2_UFS?= UFS1_ONLY I tried setting just UFS2_ONLY, but I still couldn't build boot2 with gcc 4.9 due to taking too much space. I then tried setting just UFS1_ONLY, but even then I still couldn't build boot2 with gcc 4.9. So I'm really stuck here. I'm curious how the assembly of boot2 is different between gcc 4.2.1 and gcc 4.9. I didn't try compiling with gcc 4.2.1 yet. -- Craig > -- > Craig > _______________________________________________ freebsd-toolchain@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
