Question

我正在尝试为imx6qsabresd主板的Yocto“dizzy”分支构建一个SDK。我按照https://github.com/Freescale/fsl-community-bsp-platform/blob/jethro/README.adoc的说明进行操作，唯一的区别是我使用的是头晕而不是jethro。

现在运行bitbake meta-toolchain会出现以下错误：

以上相关论点是：

-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是第一个构建的软件包之一，我想这个问题并不是针对ncurses的。

显然，编译器尝试访问绝对包含目录/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，谁在这里有过错？查看--sysroot时不考虑-I参数的编译器包括目录？或者某处的Yocto食谱有错吗？也许是Yocto的工作是为包含路径添加前缀？还有其他提示吗？

我相信您需要应用此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的回答让我到了正确的地方。这里有更多细节：

的ncurses＆＃39; public class BookcaseCatalog: IMethod<Bookcase> { private ObservableCollection<Bookcase> obsCase; public string ConnectionString { get; set; } public void Add(Bookcase obj) { //Do smth } }包含对configure.in宏的调用，该调用在CF_INCLUDE_DIRS中定义。该宏添加了一个包含路径，但没有为sysroot添加前缀，这会破坏构建。

通常修复程序会更改aclocal.m4中的宏，但这是不可能的，因为＆＃34; ncurses需要修补的autoconf213来生成配置脚本。此autoconf不可用＆＃34;。因此需要修补aclocal.m4。

作为参考，这是我为Yocto dizzy创建的补丁：

configure

由于包含不带sysroot前缀的路径，Yocto nativesdk-ncurses无法构建
