Building GCC make: *** [all] Error 2
提问by
I am trying to set up a cross-compiler for i686-elf on Ubuntufollowing the OSDev GCC Cross-Compiler Tutuorial.However, the code to set up GCC fails to build every time. I know my sources are not out of date because I sudo apt-get update'd before doing anything.
我正在尝试按照OSDev GCC 交叉编译器教程在 Ubuntu 上为 i686-elf 设置交叉编译器。但是，设置 GCC 的代码每次都无法构建。我知道我的资料来源并没有过时，因为我sudo apt-get update在做任何事情之前都会这样做。
In order to get the packages I needed, I did:
为了获得我需要的包，我做了：
sudo apt-get install g++
sudo apt-get install make
sudo apt-get install bison
sudo apt-get install flex
sudo apt-get install libgmp3-dev
sudo apt-get install libmpfr-dev libmpfr-doc libmpfr4 libmpfr4-dbg
sudo apt-get install mpc
sudo apt-get install texinfo
sudo apt-get install libcloog-isl-dev
I think there is no problem with that method?
我觉得那个方法没有问题？
Then, with gcc-5.2.0and binutils-2.25.1(in ubuntu, bintuils appears to not work with anything above that old version) I installed binutils just fine. I went to build gcc but when I typed in make, I got the following error:
然后，使用gcc-5.2.0和binutils-2.25.1（在 ubuntu 中，bintuils 似乎不适用于旧版本之上的任何东西）我安装 binutils 就好了。我去构建gcc，但是当我输入make时，出现以下错误：
Unfortunately, I can't copy+paste 30 pages in, but this all the code near the end:
不幸的是，我无法复制+粘贴 30 页，但这是接近尾声的所有代码：

And this is the part (right after that) where something really bad happens:
这是发生非常糟糕的事情的部分（紧随其后）：

make[1]: *** [configure-zlib] Error 1
make[1]: Leaving directory '/home/david/scr'

Can anyone tell me what I am doing wrong and how I would fix it?
谁能告诉我我做错了什么以及我将如何解决它？
Thanks!
谢谢！

The problem was that I wasn't installing mpc from source.
问题是我没有从源代码安装 mpc。

Unfortunately, doing this inside of an alias or bash script doesn't seem to properly launch it, so, unless this gets fixed, you might have to just store the script in a text file and copy-paste it into terminal every time you reboot.
不幸的是，在别名或 bash 脚本中执行此操作似乎无法正确启动它，因此，除非此问题得到修复，否则您可能只需将脚本存储在文本文件中，并在每次重新启动时将其复制粘贴到终端中.
To uninstall your cross-compiler, simply delete the $HOME/Documents/Cross directory.
要卸载您的交叉编译器，只需删除 $HOME/Documents/Cross directory.
As a final note, changing the installation directory or target is as easy as changing the value of $PREFIXor $TARGET, but I wouldn't recommend it, because you may run into other unexpected problems.
最后要注意的是，更改安装目录或目标与更改$PREFIX或的值一样简单$TARGET，但我不建议这样做，因为您可能会遇到其他意外问题。

In addition to --with-system-zlib, it worked for me when I use --disable-multiliboption.
此外--with-system-zlib，当我使用--disable-multilib选项时，它对我有用。
