Question

我试图将编译分解为这四个步骤，但最后一个对我来说似乎有问题。

cpp hello.cpp > hello.i
g++ -S hello.i
as -o hello.o hello.s
ld -o hello hello.o -lstdc++

我在here和here上搜索了问题，但这没有用。

以详细模式运行给了我

attempt to open hello.o succeeded
hello.o
attempt to open /usr/i686-linux-gnu/lib32/libstdc++.so failed
attempt to open /usr/i686-linux-gnu/lib32/libstdc++.a failed

attempt to open //usr/lib/libstdc++.so failed
attempt to open //usr/lib/libstdc++.a failed
ld: cannot find -lstdc++

有什么建议吗？提前谢谢。

不是直接调用链接器，而是通过gcc或g++间接调用它：

cpp hello.cpp > hello.i
g++ -S hello.i
as -o hello.o hello.s
g++ -o hello hello.o

ld：找不到-lstdc ++
