推荐答案

刚遇到你的问题，因为我遇到了类似的问题 MinGW32.

Just came across your question, because I had a similar problem with MinGW32.

对我有用的是使用 -n 不要忽略前导下划线" 选项，所以我怀疑默认选项的设置有所不同:

What did work for me was using the -n "Do not ignore a leading underscore" option, so I suspect a difference in the default option's settings:

C:\MinGW\bin>c++filt -n _Z5funcAv
funcA()

C:\MinGW\bin>c++filt _Z5funcAv
_Z5funcAv

C:\MinGW\bin>c++filt __Z5funcAv
funcA()

C:\MinGW\bin>c++filt --version
