I've been coding an Assembly operating system for 1 - 2 months, and realized it will be better if I used 32-bit and C. So I was looking into Cross Compiler stuff and such and saw that it's best to have linux. And because I have 2 drives, One 120GB SSD and a 1TB HDD, I thought I could install Ubuntu on a partition on my HDD. So I'm now running dual-boot Windows and Ubuntu, where I use Ubuntu for Linux access and OS Coding, and Windows for gaming/school/other programming stuff. I've downloaded all the stuff I need (I'm following http://wiki.osdev.org/GCC_Cross-Compiler) and I'm now trying to compile my cross compiler.

The preparation is very easy. Then we have the Binutils, which it seems I completed without errors. Then we have the GCC part, where we build our cross compiler. That's where it fails. First I check if the $TARGET-as folder exists, and it does. Then I create the build-gcc folder and enters it. I then run the which also seem to succeed. But then I run "make all-gcc". That one runs for 10 - 30 seconds, until it ends with I've searched around to fix it for 1 - 2 hours. Still can't find (I think) what I need. So I ask you, what can I do to solve it?

Where should g++ be located? I downloaded gcc-4.9.2 and assumed c++ compiler (g++) was in there, that's wrong then?

Since you are using ubuntu, you can grab it off the repo:
sudo apt-get install g++

This solved it, I forgot that when I used g++ it was on my Windows 10. I've never used g++ on my Ubuntu. Installing g++ made the trick.

What versions of binutils and gcc are you building?

What are your $TARGET and $PREFIX?

What is in the configure.log for the failed configure script? (There will probably be more than one, so you might have to dig around a bit to find the one that failed.)

I'm using Binutils 2.24 and GCC 4.9.2

$TARGET = i686-elf and $PREFIX = /home/kirdow/opt/cross

How do I get the configure.log? A bit tired today so I may need some extra help

In your build directory, run this to list all of the configure.log files.

It's also worth posting the version of GCC that you're compiling the cross-compiler with. Also check that you have C++ support (g++) installed, a quick Google suggests that if that's missing you'll get this error.

Thanks, I installed g++ like BASICFreak said, and it worked.
I've updated the post to contain the solution (with your quotes) and added a [Solved] prefix to the title.
