制造错误，gcc: “make[4]: gcc: 权限被拒绝” (Arch Linux)

Question

在尝试编译某些包时，我遇到了一个相当奇怪的make错误。 我正在运行 Arch Linux 5.6.7

例如，当尝试编译 R 3.6 时，我收到以下错误（最后是完整的 output）：

gcc -shared -fopenmp -L/usr/local/lib64 -o libRblas.so blas.o  cmplxblas.o -lgfortran -lm -lquadmath
make[4]: gcc: Permission denied

但是gcc是最新的，适用于其他安装，并且一切似乎都正确配置：

[cmasso6@cmasso6 R-3.6.3]$ gcc --version
gcc (Arch Linux 9.3.0-1) 9.3.0
Copyright (C) 2019 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

[cmasso6@cmasso6 R-3.6.3]$ which gcc
/usr/bin/gcc

我查看了 package 的Makeconf文件，其中包含以下行： CC=gcc 。 将其更改为CC=/usr/bin/gcc使其工作。

这是我的$PATH ：

/usr/lib/aurutils:/usr/lib:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl

同样， gcc正确运行。 我不知道发生了什么事。

需要说明的是，我通过更改Makeconf文件完成了此安装工作，而且我还可以使用pacman安装 R 4.0 没有任何问题。 但是，在尝试安装一些 R 包时，我遇到了同样的错误，比如ps 。 所以我想gcc和/或make存在一个普遍问题。

我不知道该怎么做，任何帮助将不胜感激！

在包含gcc二进制文件的目录之前，您在PATH的某个目录中的某处有一个名为gcc的目录。

这是 GNU gnulib 库中的一个模块中的一个错误，GNU 使用它来定位 PATH 上的内容。 见https://savannah.gnu.org/bugs/?57962
