如何将编译器的所有输出捕获到文件中? [英] How do I capture all of my compiler's output to a file?
问题描述
我正在 Linux 中从源代码 (CPP) 构建一个开源项目.这是顺序:
I'm building an opensource project from source (CPP) in Linux. This is the order:
$CFLAGS="-g Wall" CXXFLAGS="-g Wall" ../trunk/configure --prefix=/somepath/ --host=i386-pc --target=i386-pc
$make
在编译时,我收到很多编译器警告.我想开始修复它们.我的问题是如何捕获文件中的所有编译器输出?
While compiling I'm getting lot of compiler warnings. I want to start fixing them. My question is how to capture all the compiler output in a file?
<代码>$make >文件 没有做这项工作.它只是保存编译器命令,如 g++ -someoptions/asdf/xyz.cpp
我想要这些命令执行的输出.
$make > file
is not doing the job. It's just saving the compiler command like g++ -someoptions /asdf/xyz.cpp
I want the output of these command executions.
推荐答案
编译器警告发生在 stderr
,而不是 stdout
,这就是你看不到它们的原因当您将 make
重定向到其他地方时.相反,如果您使用的是 Bash,请尝试以下操作:
The compiler warnings happen on stderr
, not stdout
, which is why you don't see them when you just redirect make
somewhere else. Instead, try this if you're using Bash:
$ make &> results.txt
&
的意思是将标准输出和标准错误重定向到这个位置".其他 shell 通常具有类似的构造.
The &
means "redirect stdout and stderr to this location". Other shells often have similar constructs.
