首要问题

我正在尝试在 Ubuntu 14.04.3 LTS 上构建linuxbrew 独立安装，但原始链接中的脚本当前已损坏。我理想的答案是一个脚本，它可以一次性正确设置。我改进了脚本以减少打嗝。

修复脚本的当前进展

crti.o通过 linuxbrew 作为独立设置的一部分构建 gcc 时，我无法克服错误。但是，我找到了一些解释问题的资源：

我搜索了该文件，它就在那里！

find -name crti.o
./.linuxbrew/lib/crti.o
./.linuxbrew/Cellar/glibc/2.19/lib/crti.o

我目前遇到以下编译器错误crtn.o：

/home/hbr/.linuxbrew/Cellar/binutils/2.25.1/x86_64-unknown-linux-gnu/bin/ld: cannot find crti.o: No such file or directory
/home/hbr/.linuxbrew/Cellar/binutils/2.25.1/x86_64-unknown-linux-gnu/bin/ld: cannot find -lc
/home/hbr/.linuxbrew/Cellar/binutils/2.25.1/x86_64-unknown-linux-gnu/bin/ld: cannot find crtn.o: No such file or directory
collect2: error: ld returned 1 exit status
make[3]: *** [libgcc_s.so] Error 1
make[3]: Leaving directory `/tmp/gcc20150929-3726-hif3of/gcc-5.2.0/build/x86_64-unknown-linux-gnu/libgcc'
make[2]: *** [all-stage1-target-libgcc] Error 2

make[1]: Leaving directory `/tmp/gcc20150929-3726-hif3of/gcc-5.2.0/build'
make: *** [bootstrap] Error 2

本质上，在这一步我需要弄清楚如何确保 brew/linuxbrew/gcc 编译命令知道在哪里可以找到它。我尝试将它添加到脚本中，PATH但LIBRARY_PATH没有任何运气。因此，必须有其他方法来确保正确设置路径并找到目标文件。有任何想法吗？LD_LIBRARY_PATH

注意：我最初在这个 github 问题上寻求帮助，但他们目前无法解决这个问题。

更新

我认为这个linuxbrew gcc 公式中可能需要一个 linuxbrew 案例，它实现了在stackoverflow crti.o file missing中找到的解决方案之一。

这是原始的自制 gcc 公式供参考。

我已经用解决方案更新了linuxbrew 独立安装说明。我还创建了一个更新的linuxbrew-standalone.shTODO ，它在 14.04 中经过测试和工作，下面在评论中列出了一些小警告。

# /bin/bash
set -e
set -u
set -x

cd $HOME

# TODO: The next ln -s line breaks cross compiling with multiarch, need an alternative!
#       source: https://stackoverflow.com/a/9004026/99379

yes | ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/linuxbrew/go/install)"

# hang on here. you will have to press return
# note that even if brew doctor is a little unhappy we want to keep going
brew doctor || true

mkdir $HOME/.linuxbrew/lib
ln -s lib $HOME/.linuxbrew/lib64

# before this, you may want to `brew edit glibc` to produce compatibility for your particular kernel, for example:
# "--enable-version=2.6.18"

#brew unlink gawk
brew install glibc
brew unlink glibc
brew install https://raw.githubusercontent.com/Homebrew/homebrew-dupes/master/zlib.rb
brew reinstall binutils
brew link glibc
brew install patchelf
brew install gcc --with-glibc --only-dependencies -v
# When tested gcc was working except for the linking step, that's why it is force-accepted with ||true
# TODO: make it so force accepting isn't necessary and errors are shown correctly
brew install gcc --with-glibc -v || true
rm -f $HOME/.linuxbrew/lib/{libstdc++.so.6,libgcc_s.so.1}
brew link gcc --overwrite
export HOMEBREW_CC=gcc

brew install bzip2 curl expat
brew install git --with-brewed-curl --with-brewed-openssl --without-tcl-tk

#ln -s libncurses.so $HOME/.linuxbrew/lib/libcurses.so
brew install ruby

brew install hello && brew test hello; brew remove hello

修复问题的主要行是sudo ln -s /usr/lib/x86_64-linux-gnu /usr/lib64，但这附带了一个我对修复感兴趣的警告，因为它破坏了与 multiarch 的交叉编译。
