11:56 < michael-i> Hi all. I'm playing with t2 8.0 branch and can't get something to link against libc++. The g++ is available in my cross toolchain but the c++ lib is missing. Any extra options to toggle so it's built?
11:56 < michael-i> Many thanks, different projects keep me coming back to t2 and it's been great!

13:46 < rxr> hi
13:46 < rxr> hm, the 8.0 branch is a bit aging
13:47 < rxr> personally I did not use it in a long time
13:47 < rxr> any chance you can give trunk a try?
13:47 < rxr> we shoudl really tag some 9.0 soon-ish anyway, ...
13:50 < michael-i> I'll check package differences to trunk, see if I can spot the problem. Would it most likely be in gcc or in glibc? or..
13:50 < michael-i> Can't really figure out where libc++ is defined

14:10 < rxr> libstdc++ is part of gcc
14:10 < rxr> and build in the cross 1 stage in gcc

14:30 < rxr> 14:10 < rxr> libstdc++ is part of gcc
14:30 < rxr> 14:10 < rxr> and build in the cross 1 stage in gcc
14:52 < michael-i> ah thanks :) laptop feel asleep when I was eating
14:53 < michael-i> going back to a baseline, then will examine differences between my stuff and current trunk
14:54 < rxr> maybe gcc is not included in the cross stage or so
14:54 < rxr> simple configuraiton issue
14:54 < rxr> IIRC c++ cross compiling shoudl work in 8.0 too
14:54 < rxr> cu - need to go
14:58 < michael-i> np, thanks for the pointers
15:03 < rxr> welcome, too, cu
18:26 < michael-i> updated gcc, mpfr, gmp and mpc to trunk definitions and recompiled. All smooth but libc++ is still not present. Diving back in. Other areas which can enable/disable cpp support?
18:53 < michael-i> I do have a pkgsel.sed in my target which specifies gcc, gap, mpfr and mpc only be built in stage 0. In trunk's embedded-minimal/pkgsel.sed I see the note "# if we would need C++ this would need to be build in 1 as well"
18:54 < michael-i> I'm going to try changing my definition's .sed matches to "{ s,^. [^ ]*,X 01--------,; p; d; }
22:05 < michael-i> That worked! Just have to go and trim out the extra cruft now.
