Question

我正在尝试使用sysroot进行autotools项目的交叉编译。我用于autogen脚本的选项如下。

CC=arm-linux-gnueabihf-gcc --with-sysroot=/opt/sysroot/dir \
   --host=arm-linux-gnueabihf --sysroot=/opt/sysroot/dir --prefix=/some/dir

但是在eclipse插件中，它显示--sysroot选项无法识别，但同样的命令在终端中正常工作。

ERROR:
configure: error: unrecognized option: --sysroot=/opt/sysroot/dir
configure: error: unrecognized option: --sysroot=/opt/sysroot/dir
Try ./configure --help' for more information

如果我在eclipse中删除--sysroot选项，那么autogen工作正常，但我收到以下链接器错误。

我错过了什么？

您真的不需要使用--with-sysroot因为--sysroot已经足够了。

您的配置应该是这样的

CC="arm-linux-gnueabihf-gcc" \
CFLAGS="--sysroot=/opt/sysroot/dir" ./configure \
            --prefix=/some/dir \
            --host=arm-linux-gnueabihf

arm cross compilation unrecognized --sysroot option。（Eclipse）
