配置：错误：C编译器无法创建可执行文件

41

我正在尝试将Apache 2.2.15升级到2.2.27。运行从apache2.2.15 / build取得的config.nice时，出现以下错误：

checking whether the C compiler works... no
configure: error: in `/home/vkuser/httpd-2.2.27/srclib/apr':
configure: error: C compiler cannot create executables

我尝试过在线搜索，但没有运气。我还通过运行一个小的test.c脚本测试了c编译器，它运行良好。在线解决方案很少，例如安装“ kernel-devel”软件包，但无法解决问题。我该如何工作？

以下是生成的config.log：

    This file contains any messages produced by compilers while
    running configure, to aid debugging if configure makes a mistake.

    It was created by configure, which was
    generated by GNU Autoconf 2.67.  Invocation command line was

      $ ./configure --prefix=/opt/myapp/apache2.2 --with-mpm=worker --enable-static-support --enable-ssl=static --enable-modules=most --disable-authndbd --disable-authn-dbm --disable-dbd --enable-static-logresolve --enable-static-rotatelogs --enable-proxy=static --enable-proxyconnect=static --enable-proxy-ftp=static --enable-proxy-http=static --enable-rewrite=static --enable-so=static --with-ssl=/opt/myapp/apache2.2/openssl --host=x86_32-unknown-linux-gnu host_alias=x86_32-unknown-linux-gnu CFLAGS=-m32 LDFLAGS=-m32 --with-included-apr

从给出的输出中，您正在尝试在64位系统上编译32位apache版本。这是从intput此处配置的：

--host=x86_32-unknown-linux-gnu host_alias=x86_32-unknown-linux-gnu CFLAGS=-m32 LDFLAGS=-m32

另请参见输出线确认这一点：

configure:3629: checking build system type
configure:3643: result: x86_64-unknown-linux-gnu
configure:3663: checking host system type
configure:3676: result: x86_32-unknown-linux-gnu
configure:3696: checking target system type
configure:3709: result: x86_32-unknown-linux-gnu

这里使用的是64位构建系统，但使用32位主机/目标。再往下看，我们看到：

ac_cv_env_CFLAGS_set=set
ac_cv_env_CFLAGS_value=-m32

该标志告诉gcc产生32位对象。您的C编译器无法生成可执行文件的错误很可能是由于不存在32位工具链引起的。

测试您编译32位对象的能力

您可以通过使用-m32标志编译一个小的C示例来对此进行测试。 

// Minimal C example
#include <stdio.h>
int main()
{
   printf("This works\n");
   return 0;
}

编译：

gcc -m32 -o m32test m32test.c

如果此命令失败，则说明编译器能够构建32位对象。从编译器发出的错误消息可能有助于解决此问题。

补救措施

  1. 为64位目标构建（通过删除强制执行32位构建的配置选项），或
  2. 安装32位编译器工具链

@Vishal似乎确认您没有32位构建环境设置。您需要32位的Apache吗？
— casey 2014年
显然是的。现有的Apache 2.2.15已使用m32标志进行编译。我想将其升级到2.2.27，而不是执行全新的2.2.27安装。我可以通过构建64位目标来做到这一点吗？还是应该安装32位编译器工具链才能使其正常工作。
— 维沙尔2014年
谢谢。安装glibc-devel.i386解决了我的问题。干杯!

告诉我没有设置编译器。您安装了gcc吗？

尝试：

which gcc

在Debian上，您可能需要安装带有以下内容的构建环境：

apt-get install build-essential

或者，甚至更好：

apt-get build-dep your-package-name

特别感谢 apt-get install build-essential

可能有很多原因。对我来说，最经常发生的事情是我在命令行中或在我的环境中放置了一套CFLAGS。一年两次发生在我身上，我通常必须使用Google，因为我不记得该修复程序了。“哦，那又是”

尝试一下 echo $CFLAGS 大多数情况下，那里什么也没有。如果有可能是错误的。

在另一种情况下，我向在32位Linux上工作的配置脚本添加了一行代码，但是从那以后我切换到64位，并且-march -mfpu的某些内容现在出错了。我的意思是，这是一条错误的错误消息，它意味着存在一些错误编译，而不是表明编译器无法正常工作。

当我以为我已经安装了C编译器但实际上没有安装它时，出现了此错误。

我有一个可执行脚本来加载已执行的C模块，如下所示： 

./load_modules.sh

但是运行脚本只会在该脚本的持续时间内加载模块。要使脚本保持加载模块的状态，您必须运行：

source load_modules.sh

它执行这些行，就像将它们键入终端一样。
