当我使用 make -j 并行化编译命令时，(毫不奇怪)来自并发命令的任何编译器消息(警告/错误)都会交错。我想知道是否有办法理清这些消息。
例如，使用 make -j 我可能会看到如下内容:
Scanning dependencies of target test

[ 33%] Building CXX object CMakeFiles/test.dir/B.cpp.o

}

/tmp/D.cpp:3:1: warning: control reaches end of non-void function [-Wreturn-type]
}
^
1 warning generated.

[100%] Built target test
每个 .cpp 都会触发警告，但它们以任意顺序交错。相反，如果我发出 make，那么我会得到所需的顺序输出:
make
[ 16%] Building CXX object CMakeFiles/test.dir/A.cpp.o
/tmp/A.cpp:3:1: warning: control reaches end of non-void function [-Wreturn-type]
}
^
1 warning generated.
[ 33%] Building CXX object CMakeFiles/test.dir/B.cpp.o

}
^
1 warning generated.
[ 83%] Building CXX object CMakeFiles/test.dir/main.cpp.o

[100%] Built target test
但显然我无法利用并行构建。
有什么方法可以在并行构建期间收集来自每个命令的警告/错误吗？
(我不是很喜欢 make。如果 ninja 或其他 cmake 支持的命令行(非 GUI IDE)构建系统可以做到这一点，我我听说要接受它们)。
最佳答案
你应该使用 output sync option .
