走进龙芯3A3000（四）安装XFCE4

我想要安装KDE

我想要qtwebengine的MIPS64实现。曾经读过千里孤坟的《KDE综览》，就深深喜欢上了KDE，当时的版本还是KDE3。后来KDE4发布，千里孤坟又写了《KDE 4.0.0构建依赖详解》。最新的（2018-08-10）KDE版本是KDE Plasma 5，分为KDE-Frameworks, KDE-Plasma和KDE-Apps，当然依赖最新的Qt5。Qt5有一个模块叫qtwebengine，是将chromium包装成一个webengine并提供面向对象的API。不幸的是，在qtwebengine-5.9.5中包含的chromium的sandbox_seccomp-bpf代码没有MIPS64实现。到了qtwebengine-5.11.1，chromium有了完全的MIPS64代码，但是qtwebengine本体还是缺乏MIPS64的实现，在mkspecs/features/platform.prf中是这样写的：

defineTest(isArchSupported) {
    contains(QT_ARCH, "i386")|contains(QT_ARCH, "x86_64"): return(true)
    contains(QT_ARCH, "arm")|contains(QT_ARCH, "arm64"): return(true)
    contains(QT_ARCH, "mips"): return(true)
#     contains(QT_ARCH, "mips64"): return(true)

    skipBuild("QtWebEngine can only be built for x86, x86-64, ARM, Aarch64, and MIPSel architectures.")
    return(false)
}

没有了qtwebengine，KDE也就搭建不起来了。百无聊赖，发现轻量的XFCE，先弄一个，慢慢等吧。
