Yocto nativesdk-ncurses 构建失败，因为包含路径没有以 sysroot 为前缀

Question

我正在尝试为 imx6qsabresd 板的 Yocto "dizzy" 分支构建一个 SDK。我已经按照 https://github.com/Freescale/fsl-community-bsp-platform/blob/jethro/README.adoc 上的说明进行操作，唯一的区别是我使用了 dizzy 分支而不是 jethro。

运行 bitbake meta-toolchain 现在给我以下错误：

上面的相关参数是：

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

ncurses 是最早构建的软件包之一，我想这个问题不是 ncurses 特有的。

显然，编译器试图访问绝对包含目录 /opt/poky/1.7.3/sysroots/x86_64-pokysdk-linux/usr/include，而不考虑 sysroot 前缀 /mnt/space1/yocto-dizzy-imx6/build/tmp/sysroots/x86_64-nativesdk-pokysdk-linux。两者一起 /mnt/space1/yocto-dizzy-imx6/build/tmp/sysroots/x86_64-nativesdk-pokysdk-linux/opt/poky/1.7.3/sysroots/x86_64-pokysdk-linux/usr/include 将是正确的包含路径。

现在，谁对谁错？编译器在查看 -I 包含目录时不考虑 --sysroot 参数？还是 Yocto 食谱中某处有误？也许 Yocto 的工作是为包含路径添加前缀？还有其他提示吗？

我相信你需要应用这个 patch。具体来说，这些行

#Remove ${includedir} from CPPFLAGS, need for cross compile

sed -i 's#-I${cf_includedir}##g' ${S}/configure || die "sed CPPFLAGS"

 if [ -d "${D}${includedir}/ncurses" ]; then
        for f in `find ${D}${includedir}/ncurses -name "*.h"`
        do
        f=`basename $f`
        test -e ${D}${includedir}/$f && continue
            ln -sf ncurses/$f ${D}${includedir}/$f
        done

Answer 2

LightenS 的回答让我找到了正确的地方。下面是更多详细信息：

ncurses 的 configure.in 包含对 CF_INCLUDE_DIRS 宏的调用，该宏在 aclocal.m4 中定义。该宏添加了一个包含路径，但没有在其前面加上 sysroot，这会破坏构建。

通常修复会更改 aclocal.m4 中的宏，但这是不可能的，因为 "ncurses requires a patched autoconf213 to generate the configure script. This autoconf is not available"。因此 configure 需要修补。

作为参考，这是我为 Yocto dizzy 创建的补丁：
