[SOLVED]Stage 1 bootstrap fails in step 6: ncurses c++ error

I'm having trouble bootstrapping from a stage 1 image. The first five steps of "bootstrap.sh" work fine, but the last stage fails when trying to build ncurses. The main error is:

Thanks, but I already tried that... It gives me an error that cpp (/lib/cpp) is invalid (or failed check). I took a look, and unless I just can't find it in the normal locations, there's no g++ on my system (yet)...

Can you try (re-)emerging gcc?

Nope...still same problem. The gcc emerge completes successfully with no errors, but it still is NOT building c++/g++...

This is my first Gentoo install...did I miss some really simple step earlier in the install procedure or something? I did not set the "nocxx" USE flag... I swear - so I'm not sure why it keeps skipping c++.

I am having the exact same problem:

I'm finding quite a few people who are getting this error if they forgot their bootstrap.sh phase - they only did bootstrap.sh -f... I don't know if this applies to you (it doesn't entirely sound like it), but maybe running bootstrap.sh again might fix it?

i 'fixed' it using USE="build bootstrap" emerge ncurses

as after reading through the ebuild it seems that it doesnt use the c++ bindings if you use those tags. Not sure about implications tho!

Seems like it's a bug - reported here. From what I can tell, the bootstrap script isn't switching to a compiler with g++ support, so running this should fix it:

Thanks for all the tips. Here's what I finally found out...

First, I tried doing gcc-config as suggested by Maedhros, but no matter which gcc I select, there is still not c++ compiled for some reason. So I followed the steps listed in the bug report (using the test branch of gcc and libstdc++) and rebootstrapped, but this caused libart_lgpl to fail saying the C preprocessor (cpp) was broken. I managed to get libart_lgpl to build, but then the next package failed too.

So then I went back to the stable branch for gcc/libstdc++ and restrapped, which of course failed on ncurses again. I used exosyst's idea of setting USE to "build bootstrap", and it built ok. However, since c++ was still not built, the "emerge system" blew up in not too long. It complained about one package (I forget which) since groff was not yet built, so I did an "emerge groff"...well, that failed with some other thing missing, so I tried emerging that, then that died with missing Perl. So at that point I gave up.

I eventually went back and commented out my USE option in /etc/make.conf so it would just use all the default flags. I then rebootstrapped and it built with no problem, including the c++ compiler (g++). I then emerged system again, and aside from a few FTP MD5 checksum errors, it worked fine.

So my guess is that one of the USE options I had set is what killed it. My guess is that it's the flag that uses "hardened" mode (don't have the list of flags in front of me at the moment), although I only say that because when I did a "gcc-config -l", the only options listed were a couple of hardened modes. But that may not be related.

Anyway, it's up now, so now that I'm bootstrapped and got the system up I'll probably adjust my USE flags later. But that's after I go configure/compile the kernel, which is always fun, as I recall (although granted I haven't done it since about Slackware 97...).

Anyway, thanks for the help!

Please insert [SOLVED] into the title of your first post in this topic.

This solved a problem for me too. Just to summarize the solution for people in 3 short steps:

1) Change your USE flag to say USE="build bootstrap"
2) emerge ncurses
3) Change your USE flags back

Then continue on emerging...

Thanks,

None of the above helped me really

with the USE="build bootstrap" I'm able to build ncurses - but later, while emerge system it fails on sys-libs/db.

It seems that no c++ compiler was built!?
How do I get it? - How is it possible that gcc is build without?

That seems to be a different problem, described here: https://forums.gentoo.org/viewtopic-t-309452.html.

It seems that the toolchain eclass has recently been changed so that it only builds gcc with c, and not with c++ as well.

Thanx for your quick reply - That fixed it!

Thanks for all the help in here. Found my way here from another post that referenced this problem.
USE="build bootstrap" emerge ncurses
fixed it for me.

Every time I have a problem I find help here, usually already answered, written by some all-knowing person. Always friendly responses, well written.

As I post this from links2 while attempting my first stage 1, this just makes me smile

I've found another way functional:

I've made a search in the italian forum of "ncurses" I've have found how to solve the problem.
/* link : https://forums.gentoo.org/viewtopic-t-278722-highlight-ncurses.html */

They tells that the problem is the 1stage doesn't have g++.
So you must make this steps after emerge sync:
1) tweek your make.conf as you want
2) emerge --nodeps linux26-headers
3) USE="static"
4) emerge --nodeps gcc
5) run scripts/bootstrap.sh

It runs for a x86 subarchitecture : some problems for amd64 as said in this topic:
https://bugs.gentoo.org/show_bug.cgi?id=77718

I've tried: It works fine

The toolchain problem was a temporary mistake, and was fixed quite a while ago. Have you tried the other solutions in this thread? This seems to have worked for quite a few people:
