在Linux上的C ++源文件上运行“gcc”给出“cc1plus：out of memory allocation ...”错误信息 [英] Running 'gcc' on C++ source file on Linux gives "cc1plus: out of memory allocating ..." error message

问题描述

在Ubuntu上使用gcc编译C ++源文件时，遇到了一个令人困惑的问题。解决了这个问题，我想在这里发布它，以节省解决它的头痛。

I encountered a puzzling problem when compiling a C++ source file using 'gcc' on Ubuntu. Having solved the problem I would like to publish it here to save others the headache of solving it.

为了本报告的目的，我们有最简单的C ++ World程序，存储在main.cpp中：

For the sake of this report we have the simplest possible C++ "Hello, World" program, stored in main.cpp:

#include <stdio.h>

int main (int argc, char *argv[])
{
    return 0;
}

当我运行命令：

gcc main.cpp

错误消息：

cc1plus: out of memory allocating 1677721600 bytes after a total of 475136 bytes

我确认我正在编译正确的位元（即32位元）。我做错了什么？

I verified I was compiling for the correct bittage (i.e., 32-bit). What was I doing wrong?

推荐答案

原来我已经将C ++源文件保存为UTF-16 Unicode编码文件，在文件开头处带有前导Unicode字节顺序标记（BOM）字节。该文件在Windows系统上保存为UTF-16，提交到版本控制系统，然后签出到Linux。 gcc支持Unicode编码为UTF-8，但不支持Unicode编码为UTF-16。

It turns out I had saved the C++ source file as a UTF-16 Unicode-encoded file, complete with leading Unicode Byte Order Mark (BOM) bytes at the beginning of the file. The file was saved as UTF-16 on a Windows system, committed to a version control system, then checked out to Linux. gcc does support Unicode encoded as UTF-8, but not Unicode encoded as UTF-16.

解决方案是将源文件转换回标准的非Unicode编码。

The solution was to convert the source file back to a standard, non-Unicode encoding.
