gcc在i686上找不到bits / predefs.h [英] gcc cannot find bits/predefs.h on i686

问题描述

好的，所以我从Ubuntu 12.04 64位切换到32位并安装了 build-essential。

然后我编译并安装了GMP-5.0.5，MPFR-3.1.1，MPC-1.0，ISL-0.10和CLOOG-0.17.0。我检出了一份主要的gcc主干，并尝试用下面的配置行（从一个单独的目录）构建它：

  ../ svnsrc / configure --prefix = / usr / GCC / svn --enable -__ cxa_atexit --with-plugin-ld = / usr / bin / ld.gold --enable-threads = posix --enable-werror --enable-build-with-cxx --with-gmp = / usr / GCC / prereq / svn --with-mpfr = / usr / GCC / prereq / svn --with-mpc = / usr / GCC / prereq / svn --with-isl = / usr / GCC / prereq / svn --with-cloog = / usr / GCC / prereq / svn --enable-languages = c，c ++ 
  

配置运行良好，因此我运行了 make&&进行检查。这运行良好一段时间，但然后失败，出现以下错误：

  / home / matt / GCC / svnbuild /。 / gcc / xgcc -B / home / matt / GCC / svnbuild /./ gcc / -B / usr / GCC / svn / i686-pc-linux-gnu / bin / -B / usr / GCC / svn / i686-pc -linux-gnu / lib / -isystem / usr / GCC / svn / i686-pc-linux-gnu / include -isystem / usr / GCC / svn / i686-pc-linux-gnu / sys-include -g -O2  - O2 -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fpic -mlong-double-80 -g -DIN_LIBGCC2 -fbuilding-libgcc -fno-stack-protector -fpic -mlong -double -80 -I。 -一世。 -I ../.././ gcc -I ../../../ svnsrc / libgcc -I ../../../ svnsrc / libgcc /。 -I ../../../ svnsrc / libgcc /../ gcc -I ../../../ svnsrc / libgcc /../ include -I ../../../ svnsrc / libgcc / config / libbid -DENABLE_DECIMAL_BID_FORMAT -DHAVE_CC_TLS -DUSE_TLS -o _muldi3.o -MT _muldi3.o -MD -MP -MF _muldi3.dep -DL_muldi3 -c ../../../svnsrc/libgcc/libgcc2。 c -fvisibility = hidden -DHIDE_EXPORTS

我环顾四周，但我似乎发现的一切都是这个错误是由x86_64引起的， gcc-multilib ，因为Ubuntu和Debian使用mutiarch系统，将库分开。好的，没问题，但是我使用i686，那么为什么我需要64位库？任何帮助，将不胜感激。谢谢。

解决方案

尝试做一个

  sudo apt-get install gcc-multilib 
  

我不认为安装32位系统会更改计算机的体系结构，因为您的计算机始终是64位计算机。安装64位版本的Ubuntu应该只会提供更好的多核性能。由于您的计算机仍然是64位计算机，因此您可能需要一个可在64位计算机上编译的C编译器。因此gcc-multilib。我想。

Okay, so, I switched from ubuntu 12.04 64-bit to 32-bit and installed build-essential.

I then compiled and installed GMP-5.0.5, MPFR-3.1.1, MPC-1.0, ISL-0.10 and CLOOG-0.17.0. I checked out a copy of the main gcc trunk and attempted to build it with the following configure line (from a separate directory):

../svnsrc/configure --prefix=/usr/GCC/svn --enable-__cxa_atexit --with-plugin-ld=/usr/bin/ld.gold --enable-threads=posix --enable-werror --enable-build-with-cxx --with-gmp=/usr/GCC/prereq/svn --with-mpfr=/usr/GCC/prereq/svn --with-mpc=/usr/GCC/prereq/svn --with-isl=/usr/GCC/prereq/svn --with-cloog=/usr/GCC/prereq/svn --enable-languages=c,c++

Configure ran fine and so I ran make && make check. This ran fine for a while, but then it failed with the following error:

I looked around, but everything I seemed to find was that this error was caused on x86_64, by not installing gcc-multilib, because Ubuntu and Debian use the mutiarch system, separating the libraries. Okay, fine...but I'm using i686, so why would I need the 64-bit libraries? Any help would be appreciated. Thanks.

解决方案

Try doing a

sudo apt-get install gcc-multilib

I don't think that installing a 32-bit system changes the architecture of your computer, because your computer will always be a 64-bit machine. Installing the 64-bit version of Ubuntu should only give better multi-core performance. Since your computer is still a 64-bit computer, you probably need a C compiler that will compile on 64-bit machines. Hence the gcc-multilib. I think.
