c++ - 使用 Makefile 的交叉编译使用了错误的包含

Question

我正在尝试为 MIPS 处理器编译音频文件库

这是我的配置命令:

./configure  --build i686-pc-linux-gnu --host mipsel-gcw0-linux-uclibc --prefix=/opt/gcw0-toolchain -target mipsel-gcw0-linux-uclibc

然后当我运行 Make 时，它​​有时会包含我的计算机标题，例如:

In file included from /opt/gcw0-toolchain/usr/mipsel-gcw0-linux-uclibc/sysroot/usr/include/features.h:416:0,
                 from /usr/include/i386-linux-gnu/sys/types.h:25,
                 from ./../AudioFormat.h:26,
                 from Module.h:25,
                 from ModuleState.h:25,
                 from ModuleState.cpp:23:

                                                        ^

make[2]: *** [all-recursive] Error 1

我尝试在我的配置命令中使用所有不同的文件夹，但每次都会发生同样的错误

--build configure 选项用于指示构建环境，因为你正在做交叉编译，所以你应该使用像

./configure  --build mipsel-gcw0-linux-uclibc --host mipsel-gcw0-linux-uclibc ...

顺便说一句，--target 选项在您的情况下是不必要的，因为您没有构建编译器、链接器或类似的东西。
