Hello, I am trying to upgrade from 1.2 to 1.4rc1. The update-step1 and update- step2 scripts worked fine, but update-step3 fails with errors. I examined the update scripted and figured out that it was running: ebuild -e gcc blah blah... Since I knew that it had gotten to the gcc part of that ebuild ok, but was failing on gcc, I just did this: ebuild gcc and got the same errors. While trying to build libsupc++, and specifically del_op.c (to del_op.lo), I get this error message: xgcc: cannot specify -o with -c or -S and multiple compilations And the ebuild stops. Currently I have an unbootable system because of this. :(
Oops, turns out this is 1/2 user error, 1/2 documentation bug. This URL: http://www.freehackers.org/gentoo/gccflags/flag_gcc3opt.html referred to via this URL: http://www.gentoo.org/doc/upgrade-to-gentoo-1.4.html Instructs users to do the following (for example): CFLAGS="-march=pentium3 -O3 -pipe -fomit-frame-pointer -fforce-addr -falign-functions=4 -fprefetch-loop-arrays" CXXFLAGS=CFLAGS However, typing "echo CXXFLAGS" results in: What now? echo $CXXFLAGS CFLAGS The correct solution is: CXXFLAGS="${CFLAGS}" which works. Anyway, if I had been paying attention, I would have caught that, but its still a documentation bug, and while its not on the official Gentoo website, it IS linked to by the official gentoo 1.2 to 1.4 upgrade documentation.
Sorry about the formatting of the previous comment, looks like Konq + bugzilla doesn't peserve hard returns. Anyway, the above comment refers to the variables defined in /etc/make.conf of course.
