编译器测试失败,gcc在redhat上

标签: c linux gcc

我试图通过lsoft.com在redhat上安装LISTSERV。该软件包附带编译器测试,此测试失败。

操作系统是:

  

红帽企业Linux服务器版本6.8(圣地亚哥)

The Arch是:

  

x86_64的

编译器是:

  

gcc(GCC)4.4.7 20120313(Red Hat 4.4.7-17)

这里是完整的" gcc -v":

  

使用内置规格。

     

目标:x86_64-redhat-linux

gcc version 4.4.7 20120313(Red Hat 4.4.7-17)(GCC)

compilertest.c:

main()
{}

编译器测试命令:

gcc -O compilertest.c

错误消息:

  

/usr/lib/gcc/x86_64-redhat-linux/4.4.7 /../../../ crt1.o:无法读取符号:文件格式错误   collect2:ld返回1退出状态

该文件作为真实文件存在(即不是符号链接):

  

-rw-r - r-- 1 root root 1240 Jan 28 2016 /usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../crt1.o

那么,我错过了什么?使用32b而不是64b编译的东西?我错过了一个图书馆或者版本错误吗?

此错误消息:

  
    

/usr/lib/gcc/x86_64-redhat-linux/4.4.7 /../../../ crt1.o:无法读取符号:文件格式错误collect2:ld返回1退出状态< / p>   

表示链接器找到了一个32位目标文件,它预期为64位,或者反之亦然。您可以通过使用file命令检查相关文件来确定哪个。为此目的readelf有点矫枉过正,但它也完成了工作。我们知道你的是一个32位ELF目标文件,因此编译器可能需要一个64位的文件。

您提出的路径规范化为/usr/lib/crt1.o。在RHEL6上,属于32位glibc-devel包(64位模拟位于/usr/lib64)。 32位ELF对象正是该文件应该是什么,因此如果编译器期望64位对象,那么它就会出现严重错误。

我最好的猜测是,从源代码或来自某个其他基于RPM的发行版(甚至是不同版本的RHEL)的软件包安装会为您创建一个无法使用的环境。如果您在/usr/bin以外的地方有GCC的源代码安装副本,那么删除它(至少从路径中)可能足以解决您的问题。命令which gcc可能有助于确定您是否获得了流氓gcc而不是RHEL的标准版。

否则,最好的办法是删除gcc和开发库的所有副本,然后从官方软件包存储库重新安装。要删除并重新安装的主要软件包是&#39; gcc&#39;和&#39; glibc-devel&#39 ;;删除这些也可能导致其他工具和开发库被删除。我建议同时删除任何&#39; compat-gcc&#39;包。不要试图删除主要的glibc&#39;但是,如果你以某种方式设法做到这一点,它会使你的系统无法运行。
