Compiler errors Yocto nativesdk ncurses无法生成，因为包含路径未以sysroot作为前缀

我正在尝试为imx6qsabresd板的Yocto“dizzy”分支构建SDK。 我已经遵循了在的说明，唯一的区别是我使用了dizzy branch而不是jethro

运行

bitbake元工具链

会出现以下错误：

上述相关论点如下：

• -I/opt/poky/1.7.3/sysroot/x86\u 64-pokysdk-linux/usr/include

• --sysroot=/mnt/space1/yocto-dizzy-imx6/build/tmp/sysroot/x86_64-nativesdk-pokysdk-linux

ncurses是首批构建的软件包之一，我想这个问题并不特定于ncurses

显然，编译器试图访问绝对include dir

/opt/poky/1.7.3/sysroot/x86_64-pokysdk-linux/usr/include

，而不考虑sysroot前缀

/mnt/space1/yocto-dizzy-imx6/build/tmp/sysroot/x86_64-nativesdk-pokysdk-linux

。两者加在一起，

/mnt/space1/yocto-dizzy-imx6/build/tmp/sysroot/x86_64-nativesdk-pokysdk-linux/opt/poky/1.7.3/sysroot/x86_64-pokysdk-linux/usr/include

，将是正确的include路径

现在，谁是这里的错？编译器在查看

-I

include dirs时没有考虑

--sysroot

参数？或者Yocto的食谱中有错误？也许Yocto的工作就是给include路径加前缀？还有其他提示吗？

我认为您需要应用这些提示。具体来说，这些线

#从cppfaglass中删除${includedir}，需要交叉编译

sed-i's#-i${cf#u includedir}##g'${s}/configure | | die“sed CPPFLAGS”

闪电的回答让我找到了正确的地方。 以下是一些更详细的信息：

ncurses的

configure.in

包含对

CF\u INCLUDE\u DIRS

宏的调用，该宏在

aclocal.m4

中定义。该宏添加了一个include路径，但没有使用sysroot作为前缀，这会破坏构建

通常情况下，修复程序会更改

aclocal.m4

中的宏，但这是不可能的，因为“ncurses需要修补的autoconf213来生成配置脚本。此autoconf不可用”。因此，需要对

configure

进行修补

作为参考，这是我为Yocto dizzy创建的补丁：

谢谢！虽然该补丁不适用于我的Yocto版本，但它向我指出了问题的根源，我设法以非常类似的方式修复了它。
