没有完整路径的gcc：尝试执行'cc1'时出错：execvp：没有此类文件或目录

时间：2019-06-28 16:37:18

标签： c linux gcc

我从源代码安装了gcc 8.3.0。

如果我将gcc与完整路径一起使用，则效果很好。

$ /usr/bin/gcc test.c

但是，如果我使用不带完整路径的gcc，则会导致错误：

$ gcc test.c
gcc: error trying to exec 'cc1': execvp: No such file or directory
  • 编译.cpp文件时，'cc1'更改为'cc1plus'

我可以解决此问题吗？还是此gcc特定（必须使用完整路径）？

样本来源：

//test.c or test.cpp
void main(){}

没有完整路径的跟踪（错误：1）：

  • 为什么gcc使用相对路径找到cc1 / cc1plus ...？
  • 我认为gcc应该使用绝对路径查找'/usr/libexec/gcc/i686-test-linux/8.3.0/'目录。

gcc version 8.3.0 (TEST Embedded Linux Toolchain for [i686])```

我已经测试了这些更改，但没有解决：

  • '/ usr /'到'/ usr'
  • 删除：在FLAGS中为“ -static”，--disable-bootstrap
  • '/ include'到'/ usr / include'：这将从'/ usr / usr / include'中读取包含文件。无法使用。

我的linux环境只有：

  • 内核（v4.19.34，defconfig + Hyper-V模块：[y]）
  • busybox（v1.30.1，所有小程序）
  • binutils（v2.32）
  • gcc（v8.30）
  • musl（v1.1.22）
  • libstdc ++ v3（带有musl）

注意：我的linux没有任何软件包管理器。因此不能像“ sudo apt-get install g ++”那样使用它

1 个答案:

答案 0 :(得分：0)

我用简单的解决方案解决了这个问题。

export PATH

此命令后，将使用相对路径进行编译。

找到这个的路：

  • 我测试向libexec添加PATH是否可以编译。

$ PATH=${PATH}:/usr/libexec/gcc/i686-test-linux/8.3.0/->成功

根据strace日志，我认为gcc不使用$ PATH搜索cc1 / cc1plus。为什么？

  • 我测试/ usr / bin的PATH是否可以编译。 （由于错误）

$ PATH=${PATH}:/usr/bin->成功

  • 为什么成功？我认为PATH已经包含“ / usr / bin” 
$ echo ${PATH}
/sbin:/usr/sbin:/bin:/usr/bin
  • 我测试是否简单地通过了$ PATH。

$ PATH=${PATH} gcc->成功

  • $ gcc和$ PATH=$PATH gcc之间有什么区别？
$ set
HOME='/'
HOSTNAME='TEST0'
IFS='
'
LINENO=''
OLDPWD='/'
OPTIND='1'
PATH='/sbin:/usr/sbin:/bin:/usr/bin'
PPID='2701'
PS1='\w \$ '
PS2='> '
PS4='+ '
PWD='/'
SHLVL='8'
TERM='linux'

$ export
export HOME='/'
export OLDPWD='/'
export PWD='/'
export SHLVL='8'
export TERM='linux'

哦，不将PATH作为环境变量导出。仅作为 shell 变量存在...
