Sun Studio C++ “不以换行符终止”警告——如何抑制？

发布于 2024-08-15 14:04:17 字数 234 浏览 3 评论 0原文

我已经将相当多的代码从 Win 移植到 Solaris，这是我遇到的问题之一 - 我收到了一堆警告：

Warning: Last line in file is not terminated with a newline.

我喜欢警告 - 但由于警告的数量太多，我担心我可能会错过更重要的警告。

我应该指定哪个编译器 (cc) 选项来使其静音？

谢谢。

I have ported a fair bit of code from Win to Solaris, one of the issues I have -
I am getting a heaps of warnings:

Warning: Last line in file is not terminated with a newline.

I like warnings - but because of the sheer amount of those I am afraid I could miss more important one.

Which compiler (cc) option should I specify to silence it?

Thanks.

或者您可以在每个文件的末尾添加一个空行。

一个快速的 shell 脚本

find . -name "*.cpp" -exec echo "" >> {} \;

Or you could add an empty line to the end of each file.

A quick shell script

find . -name "*.cpp" -exec echo "" >> {} \;

虽然我认为马丁修复原始源文件的解决方案会更好，但如果您确实想禁用警告，那么此页介绍 -erroff 标志，您可以使用该标志来禁用特定警告。在您的情况下，添加

-erroff=E_NEWLINE_NOT_LAST

到 CC 命令行以关闭换行符警告，例如：

# Display the warning and the warning tag name.
/opt/forte/sunstudio11_patch2/SUNWspro/bin/cc -errtags=yes test.c
"test.c", line 1: warning: newline not last character in file (E_NEWLINE_NOT_LAST)

# Disable the warning.
/opt/forte/sunstudio11_patch2/SUNWspro/bin/cc -erroff=E_NEWLINE_NOT_LAST test.c

Although i think Martin's solution of fixing the original source files would be preferable, if you really want to disable the warnings then this page describes the -erroff flag which you can use to disable specific warnings. In your case add

-erroff=E_NEWLINE_NOT_LAST

to the CC command line to switch the newline warning off, e.g.:

# Display the warning and the warning tag name.
/opt/forte/sunstudio11_patch2/SUNWspro/bin/cc -errtags=yes test.c
"test.c", line 1: warning: newline not last character in file (E_NEWLINE_NOT_LAST)

# Disable the warning.
/opt/forte/sunstudio11_patch2/SUNWspro/bin/cc -erroff=E_NEWLINE_NOT_LAST test.c
