Question

我正在尝试在本地安装gcc-4.9.0。我给出了以下命令来配置安装

LD_LIBRARY_PATH=/home/user/gmp-6.0.0/lib:/home/user/mpfr-3.1.2/lib:/home/user/mpc-
1.0.2/lib ./configure --prefix=/home/user/gcc-4.9.0-latest --with-
gmp=/home/user/gmp-6.0.0 --with-mpfr=/home/user/mpfr-3.1.2 --with-
mpc=/home/user/mpc-1.0.2 --enable-languages=c,c++ --disable-multilib

它配置时没有给出任何错误，然后当我make install时，我收到以下错误

gcc-4.9.0> make install
make[1]: Entering directory `/home/user/softwares/gcc-4.9.0/build/gcc-
4.9.0'
/bin/sh ./mkinstalldirs /home/user/gcc-4.9.0-latest /home/user/gcc-4.9.0-latest
/bin/sh: line 0: cd: host-x86_64-unknown-linux-gnu/fixincludes: No such file or    
directory
make[1]: *** [install-fixincludes] Error 1
make[1]: Leaving directory `/home/user/software/gcc-4.9.0/build/gcc-4.9.0'
make: *** [install] Error 2

任何人都可以帮我解决这个问题吗？

机器运行RHEL 4，linux内核为2.6.9-67.ELsmp

编辑：我在config.log文件中发现了错误

configure:4970: checking whether g++ accepts -static-libstdc++ -static-libgcc
configure:4987: g++ -o conftest -g -O2   -static-libstdc++ -static-libgcc conftest.cpp

EDIT2：

我跑了make并收到以下错误

Answer 1

看起来你构建了gcc包装之外的所有依赖项。包含一个脚本，它将所有依赖项收集到gcc包中，并将它们作为gcc构建的一部分包含在内：

gcc-4.9.0/contrib/download_prerequisites

这应简化您的初始配置。

不确定用于构建4.9.0 gcc编译器的编译器和/或版本。如果你仍然在RHEL 4上，假设3.4-ish可能需要构建/安装4.2.x gcc，以便逐步获得构建4.9.x所需的支持，因为缺少对RHEL 4的预构建gcc支持。＃39;停留在较旧平台上的价格。

Answer 2

两个问题：

首先，您不应该在源目录中构建编译器。它有时似乎可行，但它不受支持且编译器开发人员不这样做，所以你不应该这样做。创建一个外部obj目录，并在那里构建：

mkdir obj
cd obj
/path/to/src/configure ...blah...blah...blah

其次，你错过了一步：

make
make install

我知道很多项目都设置了makefile，以便make install正常工作，但引导编译器比大多数项目复杂一点。
