建筑GCC制造商:*** [全部]错误2

5 c ubuntu gcc makefile g++

我正在尝试OSDev GCC交叉编译器教程之后为Ubuntu上的i686-elf设置交叉编译器。但是,设置GCC的代码每次都无法生成。我知道我的消息来源并不过时,因为我sudo apt-get update在做任何事情之前就已经过时了。

为了获得我需要的软件包,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

我认为这种方法没有问题吗?

然后,使用gcc-5.2.0binutils-2.25.1(在ubuntu中,bintuils似乎不适用于该旧版本之上的任何版本),我安装binutils很好。我去构建gcc,但是当我输入make时,出现以下错误:

不幸的是,我无法复制+粘贴30页,但这几乎所有代码都快结束了:

这是发生严重错误的部分(紧随其后):

checking dynamic linker characteristics... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.
Makefile:9590: recipe for target 'configure-zlib' failed
make[1]: *** [configure-zlib] Error 1

谁能告诉我我在做什么错以及如何解决?

谢谢!

问题是我没有从源代码安装 mpc。

这是完成的文件(setup-gcc.sh):

安装后,您可以使用以下命令运行它:

export PREFIX="$HOME/Documents/Cross/Install"
export TARGET=i686-elf
$PREFIX/bin/$TARGET-gcc --version

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.

要卸载您的交叉编译器,只需删除 $HOME/Documents/Cross directory.

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。
