gcc:致命错误:Lims.h: macos上没有这样的文件或目录

Question

我试图在MacOS10.14.5、Python3.7和gcc 4.7上安装Python (https://pypi.org/project/python-Levenshtein/)。但以下几个方面都失败了：

/opt/local/lib/gcc47/gcc/x86_64-apple-darwin16/4.7.4/include-fixed/limits.h:169:61: fatal error: limits.h: No such file or directory

完整的日志是：

有趣的是，文件实际上存在于我的mac上，即：

felix@fxa-2:~$ ls /opt/local/lib/gcc47/gcc/x86_64-apple-darwin16/4.7.4/include-fixed
README       limits.h     math.h       stdint.h     syslimits.h

Answer 1

造成这个问题的原因是通过macport安装了gcc (4.7)，以及xcode附带的另一个。第一个是用的。通过卸载带有macport的老gcc，xcode的gcc再次被使用，而也可以被安装(并编译它的C代码)。

Answer 2

在我的机器上(不是Mac，但结果应该转换)，…include-fixed/limits.h包含以下内容

#ifdef _GCC_NEXT_LIMITS_H
#include_next <limits.h>                /* recurse down to the real one */
#endif

在我的例子中，“真实的”似乎是/usr/include/limits.h：

$ <<< '#include <limits.h>'  gcc -E -xc - |grep limits
# 1 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/limits.h" 1 3 4
# 34 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/limits.h" 3 4
# 1 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/syslimits.h" 1 3 4
# 1 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/limits.h" 1 3 4
# 194 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/limits.h" 3 4
# 1 "/usr/include/limits.h" 1 3 4
# 26 "/usr/include/limits.h" 3 4
# 27 "/usr/include/limits.h" 2 3 4
# 183 "/usr/include/limits.h" 3 4
# 1 "/usr/include/linux/limits.h" 1 3 4
# 184 "/usr/include/limits.h" 2 3 4
# 188 "/usr/include/limits.h" 2 3 4
# 195 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/limits.h" 2 3 4
# 8 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/syslimits.h" 2 3 4
# 35 "/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/include-fixed/limits.h" 2 3 4

我的包裹经理说/usr/include/limits.h is owned by glibc 2.29-1。

而且你肯定有Mac的libc (不知道它叫什么)代替了Glibc。可能问题是，您的系统上的libc比gcc配置的libc更新得多(gcc 4.7现在已经相当老了)，因此它希望在较新的版本中有被移动到另一个位置的头。

这是我的猜测。检查你的系统找出答案。此外，你也可以尝试一个较新的gcc建筑，如果这是一个选择。

Answer 3

在我的例子中，默认的gcc是在/usr/local/bin/gcc中，它是到/usr/local/bin/gcc-4.9的软链接。

我用brew install gcc重新安装了brew install gcc，并将/usr/local/bin/gcc重新链接到新的gcc，这在我的例子中是/usr/local/bin/gcc-10。

对于g++也做了同样的事情，然后问题解决了。
