我使用的是 RedHat Linux 环境，我没有 root 权限（我使用的是付费服务器帐户）。
每次我尝试在尝试设置和安装的新软件包上运行“./configure”时，都会遇到由于 C 编译器和/或 gcc 问题而出现的问题。
我的主要问题是尝试在本地安装 python，以便我可以安装某些 Python 工具，例如 Flask 和 Pip。这是我尝试运行 Python 的“./configure”时出现的错误消息：
checking for --with-universal-archs... 32-bit
checking MACHDEP... linux2
checking EXTRAPLATDIR...
checking machine type as reported by uname -m... x86_64
checking for --without-gcc... no
checking for gcc... gcc
checking for C compiler default output file name...
configure: error: C compiler cannot create executables
See `config.log' for more details.
以下是 config.log 文件的内容：
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by python configure 2.6, which was
generated by GNU Autoconf 2.61. Invocation command line was
$ ./configure

有人知道这里的问题是什么吗？我的 gcc 设置有问题吗？我是否在某个地方缺少所需的库？我使用的是 gcc 版本 4.4.7
答案1
日志中实际的错误行是：
gcc: error trying to exec 'as': execvp: Permission denied
问题可能是您as的 PATH 中有一个文件不是“真正的”汇编器，通常在/bin/as.更改您的 PATH，使/bin和/usr/bin位于列表中的第一个位置，位于当前顺序/usr/local/jdk/bin /usr/lib64/qt-3.3/bin /home/midgar77/perl5/bin和之前/usr/local/bin。
答案2
这个错误是由于
configure:2695: checking for C compiler default output file name
configure:2722: gcc conftest.c >&5
gcc: error trying to exec 'as': execvp: Permission denied
这是 Ubuntu 系统上的一个已知问题，请参阅下面的 AskUbuntu ussue。 （我知道OP正在使用RedHat）应该联系系统管理员来更改权限以使编译器按预期工作：
